I discovered a leak on the power steering reservoir of my 996tt. It was caused by a broken grommet.  I need help to find a grommet like in the picture below. Can anybody give the part number of this red grommet or where can I get a replacement.  Thank you.

I also had P1109 input variables charge measurement on my 996TT. A few days ago, I erased the fault codes with my Durametric and the CEL was gone. Then, I went out for a short drive this Christmas morning and suddenly the CEL lit up after about a mile from my home. I went back home, plugged the Durametric and erased the code. Now, there is no CEL, but Im afraid it will come back again unless I find the cause.

I just replaced my TB and plenum with an Agency Power Plenum and throttle body from Vivid Racing. It was fine after installing the TB for several weeks until one morning the CEL lit up and the P1109 came out in my Durametric. Can anyone give any information on what to do?

I replaced my 996TT stock throttle body with an Agency Power TB and plenum from Vivid Racing. It gave my 996TT great throttle response. However, after a few days, I got a CEL and by using a Duramteric and I found the code P1109. I erased the fault code and the CEL was gone.

After a few days, I decided to move the 996TT to another spot in my garage and the CEL lit up again. I used the Durametric again to erase the fault code.

I read a blog at reentech (cant remember which one) where it said to turn on the ignition on for 30 seconds and wait for clicking sound at the engine. It meant that the TB has reset. So, thats what I did after erasing the fault code with the Durametric. So far, the CEL hasn't lit up.

Can anyone tell me what to do next time if the P1109 fault code crops up again? Thanks.

I reflashed my 997tt with a softronic. You'll realize the difference after you download the reflash. It will be a different car when you drive it and step on the gas. Its worth the $1500+ price tag. Together with an exhaust and free flowing air filters, you'll love your 997tt more. :king:

Thanks. I pulled down the starter. The solenoid needs cleaning. Cleaned it over the weekend. Hopefully, ill install the starter tonite and hope it now cranks and start the car.

Im having problems getting my 07 997tt engine started. I have to turn the ignition switch several times to get the engine started. But on my last 10 attempts to start the car, I coulnt start the engine. All I hear is "click".. My battery is new at 12.72 volts. I tried to use a jumper and still couldnt start the car. I now believe the problem is the starter solenoid. Can someone help me find the replacement solenoid in the internet? Please send me a link. Thanks

Tried it last night. Wont fit. Rear tires hit the inner wall of the wheel well. :(

Thanks PhilippJ, Kabayan ba tayo? :)

Yes, In fact, I ordered this morning a Softronic ECU from Billy of Vividracing. Ill just wait for the cables. The 997-1 is already quick in its stock set-up, what more with the Softronic reflash. 555hp will not be a problem to achieve. Best regards :cheers:

Has anyone have any experience on a Softronic ECU reflash from Vividracing? I want to know how the car felt after the reflash.

Hello Porsche 996TT enthusiasts,

A friend of mine gave me a set of 19" 997 1st gen GT3 rims. I was wondering if this would fit into my 996tt. Can anyone give an advise or experience on this?

Thanks.

You really need it to be calibrated with a PIWIS. Happened to me already. The durametrics has no calibration features. Only diagnostics and to erase fault codes.

I have a friend who has a piwis. I just followed the same instructions from Loren on this blog and my gas guage is now OK.

Calibrating fuel level sensor system

Note:

- Calibration is necessary after replacement of the fuel tank, fuel level sensor or instrument cluster.

- The fuel level sensor system need not be calibrated if the battery was disconnected or a plug connection on the instrument cluster or fuel level sensor was removed. The values remain stored in the instrument cluster.

- A range on remaining fuel of less than 15 km is not displayed in the instrument cluster.

1. Disconnect the battery and cover terminal or battery.

2. Remove cap over the fuel level sensor system.

3. Remove fuel level sensor.

4. Safely -- Using a fuel extractor, completely drain the fuel tank through the fuel level sensor opening.

5. Make sure that the two recesses on the left and right−hand sides of the tank are emptied completely.

6. Reinstall the fuel level sensor and, with "ignition off", fill the tank with 28 liters of fuel.

7. Perform tank calibration with the Porsche System Tester 2 (or PIWIS tester) :

- Select vehicle type (911 Carrera)

- Select control modules

- Select instrument cluster

- Select menu item "Tank calibration"

- Confirm calibration

8. The fuel level sensor system has now been calibrated.

Thank you Loren,

In item 7, are we going to turn on the ignition to perform the tank calibration?

We're goin to do the PIWIS calibration tomorrow.

Hi Guys,

Can anyone send me a proceduaral instruction or a link on how to calibrate the fuel guage of myn996TT using a PIWIS?

Thanks. Would appreciate your help.

Hi guys,

has anybody had a ecu remap on a 996tt? thinking of having it done from revo in the uk, is it worth it and can you feel the the results?

Yep. Got a softronic with launch control. Big, big difference. Worth all the money. After I downloaded the remap, the idle became more stable and the rev was more responsive. I shifted the 996tt on first gear and rev to 5200rpm. Then released the clutch and the 996tt launched like a bullet. A remap is worth it.

I have a stock 2001 996 TT

I had the CEL come on over the weekend and the codes were P1411 and P0410. I'm familiar with this issue as I fixed a secondary air problem with my prior car that was a Boxster. In doing some research on the TT I found that replacing the diverter valves (called shut-off valves in PET) have fixed this problem for some people. The fan does run at startup so I decided to do a quick check on the diverter valves - suck on a hose attached to the hose connector on top of the valves. One of the valves could hold the vacuum, but the other could not - of course the bad one is the one toward the front of the car. I have the following questions / request for comment.

Do I need to replace both diverter valves or can I just replace the bad one?

It looks like the diverter valves vacuum hose is related to the secondary air vacuum lines and wondered if anyone had any comments on whether a bad diverter valve could cause the codes listed above.

If you cam get a new diverter valve, just replace the bad one and see what happens. If it still doesnt hold the vaccum, then get another one. I replaced mine with Agency Power DVs and I didnt have any problem. It cost around $260+.

A 996TT "S" model has yellow brake calipers. Standard 996TT has red colored calipers. Appearance are the same except the X50 kit.

Hi everyone.

Well all I can say OMFG this map is very very good. It transforms the car into a beast. Throttle response is far better than stock by miles. The engine comes on boost much sooner and goes to 1-1.2 bar of boost depending on how and when you mash the throttle. it just seams to rev better and run smoother to be honest. by far better than the 6 grand X50 turbo s pack and its not 6 grand either and it'll give you 490 BHP instead of 450. Of coarse as it is a loaded up map I have no idea of my final BHP but all I know is that its far smoother and faster now! well worth the money I would say.

Install

well sending the files took 10 mins I waited about a day and half to come back. I got my maps today, unziped them to the desktop as it says, setup my battery charger as you dont want the batery going flat half way through that would be bad! plugged in the cable to the lap top, drivers come with the software for this. disabled the antivirus and plugged into the car. turned the car on, not started but on, all lights light up on the dash. nothing scary at this stage.

double clicked the map tuned file and it opens the software. it says do you want to install this!. yes I do! hit yes. then it took me from 6pm till 11pm to get the thing working!

dont worry it was not the Softronic files or software. Every time it got to connecting after the cable check step it stopped with no error message apart from "file uploaded turn key off then on" hmmm what to do know I thought, has it upload! I didnt think it had as the progress bar was only 5 blocks through and I started to worry. I could see the light on the cable was green and it goes red when writing the file or reading anything from the ecu. I decided to turn off the car, turned it back on, nothing the same message and the program did not continue.. hmmmm getting more worried now! turned off the car unplugged the cable and tried to start the car! it started so i knew i was ok. tried it again and again with no joy the same thing every time for about 3 hours! I put the battery on charge at the start but it was still going flat so I stopped and waited for it to charge and had a think about it. while doing this I then saw a log file on the desktop and opened it. It said cable cannot be registered connection closed. I knew from that file and that it hangs just at the connecting stage in the software that something was stopping it from connecting either to the web or the car. I tried to open all my ports in Norton on my computer but still no joy and we tried a few things even leaving norton turned on. So I got my house mate get his laptop and download all the stuff to his computer he opened all his ports (not in Norton as he doesnt use it) and hay presto it worked first time! we had tried it on his before we opened the ports and it did the same thing as on my laptop. the file took around 5 mins to upload. turn off the car, unplugged the cable then started the car. It worked the smile on my face was soooo big. stopped the car and my neibour came out and complained about me starting my car so late. I muttered some rude words back that sent them inside!! bloody old people!! got in the car and made as much noise I could while i went to test her out.. all I can say is get one, get one now. :D but make sure all your ports are open. I havent worked out whats stopping it from working on my PC but ill speak to softronic and see what they say as they need to put an error message up when this happens so people know waht the hell is happening as it is scary messing around with this stuff.. now my car is scary fast well worth it.

I'm in the Uk too, UK 996 turbo readers, you need one of these re-maps. sod the 3 grand exhaust buy this!! Darran at Vividracing is very nice and I paid allot less money for my DV's and this tuneup than whatI would have paid for them from the UK. I'll be using Vivid racing from now on..

O I got my DV'd fitted too managed to get thos stupid clips off after allot of help from my mate. the refitment of the new ones was easy with jubilee clips. I the cleaned my engine bay and it looks great now. took around 3 hours to it all and the cleaning.

thanks guys any questions about it just shout.

Atomicveilside:

Just downloaded my softronic to my 996TT. You are absolutely right its OMFG fast....Thanks

good luck!

after the flash you will not believe that is the same car!

Alex_55,

Yes, its definitely a different car now. I cant believe it. Thanks

gpt817,

What type of mods do have on your 996TT?

I have a stock 996TT and would like to, initially, get an ECU flash as my first mod.

aquinto

Hi aquinto,

I have a K24 turbo and headers from an X50, Agency Power Diverter valves, EVOMS wastegate, Samco F and intercooler hose and K&N panel filter. I also have a Sach Motorsports clutch. I still have the stock 996TT exhaust but I wil remove the cat to make a free-flowing exhaust. The after market exhaust are too noisy for me. The car came with at Tubi exhaust when I got it but I took it out and sold it. It was too noisy and deafening.

For me, the Softronic is a good investment. You can add the other mods after you reflash the ECU. They will send you back your old original file which you can install back if you're going to sell the car or don't like the reflash. The torque of my 996TT after the reflash gave me an andrenalin rush. It accelerates like no other cars. I have an EVO8 and a moded Nissan Skyline GTR TT, but my Softronic-reflashed 996TT is definitely stronger and accelerate faster.

I finally intalled the Softronic reflash to my 02 996TT.

I followed all of Scott's instruction to the letter: plug to the car a battery charger set at 10 amperes; extracted the file from my email account to the desktop; checked if there's an internet connection by going to the softronic website, www.softronic.us; disabled all virus scan, windows auto-update, windows messenger etc. plugged in the cable to the laptop and the OBDII port of the 996TT; and switched on ignition.

Then, I double clicked the zip file.When the softronic window appeared, I clicked "Yes" to proceed to download to the ECU. I looked at the status green bars and timed it. It took only 3mins 56 seconds for the "finished" box to appear.

Instead of using a wi-fi or aircard, I wired and plugged in my laptop direct to my DSL connection. In that way, the internet speed would be faster. Probably, thats the reason why it just took me under 4 minutes to install the softronic reflashed file to the ECU. I strongly recommend softronic buyers to go this way to connect to the internet.

When the "finished" button appeared, I clicked it right away, switched off the ignition, removed the cables and the laptop from the car.

Then, I started the car. Revedd it and I notice a big difference in throttle response. It was very responsive and aggressive, just like a race car. I Took the car for a test drive and WOWWWW. OMG, its a different car now!!!!! The torque was incredible. The 996TT virtually flies. Your back will stick to the car seat.

It was worth the wait for Softronic to send back my file... Again thanks to BJ of Vivid Racing and of course, conratulations to Scott for a wonderful product, more power to you!!!!.

I strongly recommend the Softronic reflash to all 996TT owners. :thumbup:

Finally, I received the email containing the softronic file and my original file for my 996TT reflash.

I will download the reflashed file tomorrow. Wish me luck so that no snafu will happen. Read and re-read the instructions to the letter.

Thanks to BJ of Vivid Racing and to Scott of Softronic.

Ill keep you posted after the reflash.

Got an email from Vivid racing and said softronic wasn't able to get my files or was corrupted. So, I was told to redo the entire process of extracting and uploading the files again this morning. It took only 19 seconds to upload and get the "upload completed" message.

Will just have to wait for the zip files to be emailed back.

I cant wait to get the reflash. The Police here don't ticket you for speeding. Practically, there is no speed limit here thats why they call our place "Paradise". :beer:

Its been more than 48 hours since I uploaded my ecu map to softronic. I havent received my reflashed zip file. I've filled up my name, email address, year, model etc.. before uploading the file.

Will wait for another 24 hours before I call vivid racing.

GPT 817

I noticed on the Vivid site they have several flash's avaiable for 996TT. Which on did you go with? Have you experienced any problems since install? Any issues with codes etc?

thanks

I got the flash for 996TT with launch control. I got the softronic cable from Vivid racing several weeks ago but I was so busy at work that I just worked on it this morning.

I've just extracted by 996TT ecu file and uploaded it to Softronic. Im just waiting for them to email me back the reflashed zip file.

It just took me less than 5 minutes to extract the ECU map from my car and 20 seconds to upload it back to them. Its important to read the instructions and disabled the virus scan and windows update.

Ill let you know when they email back my reflashed zip file and install it to my 996TT.

My 2002 996TT ran out of gas when the fuel guage was at 1/2. I filled her up and used it for a while and tried to checked the fuel tank. The guage showed 3/4 gas. I removed the gasoline in the tank and I got 33 liters out. Then, I checked on the hoses inside and see if it obstructed the fuel float. Then, I Tie wrapped one of the hose towards the firewall, as suggested in one of the renntech.org topics to avoid obstructing the float.

Then, I placed back the 33 liters, which should be at least 1/2 of the 64-liter fuel tank. However, the fuel guage reading is still at 3/4? I also cleaned the fuel float switch with WD40 to remove possible fuel gums. No change.

Is there any other way to fix this problem? :thankyou:
