After a rather spirited drive this morning here in South Florida, I heard a strange noise coming from my engine.  As my 911 is a Cabriolet, I first thought it was another car around me.    When I got back to the garage I confirmed it was indeed me :(

In summary:

• The sound goes on for 30 seconds then would stop.  It would take another 2-3 minutes then it would come back on.
• Something that caught me by surprise was that I turned the car off and was going to turn it back on to see if it continued.  When I just turned the key to turn-off the engine immobilizer the sound came on even though I had not physically cranked the engine yet.
  • When I started the engine it did not come back on.   I let it run for another 5 minutes but the noise did not return
• I checked to see if it was throwing any ODB2 codes with my Durametric, however, all was clear.
• Oil levels are fine
•  
• I have enclosed two videos
  • One is with the engine running (and the sound disappearing)
  • The second is when I turned the key, but not yet cranked the engine.

Any advice/insight into what it could be would be appreciated.    Also would like to know can I drive it to my mechanic (assuming that I would need to), would I be causing any long term problems?

Thanks - Steve

Thanks Loren.   I did a quick 15-minute ride yesterday and the codes have not come back yet.

I just had my 1998 993 Cabriolet worked on by a local Porsche mechanic to fix a broken shift linkage.   The engine had some leaks as well which we had spoken about a year earlier.    I decided to have them repaired and since the engine was partly taken apart, they changed the ignition wires as they were the original wires and replaced the belts.  

After 50 miles on my first highway trip since the repair, the check engine light came on.   I hooked up my Durametric and pulled the following codes:

107 - Supply Voltage

169 - IACV Make Winding

168 - IACV Break winding

35 - Oxygen Sensing range 1 (cylinder 4-6)

I reset the codes, re-started the engine let it idle for about 5 minutes - the codes stayed off.

Is it OK to drive the car in this condition or is it a sign of some bad stuff going on?

Any insight into why these codes would pop after such a repair above?

Any help would be appreciated.

Thanks - Steve

Well they had to replace the shifter rod as one end had disintegrated (hence the disconnection of the linkage), the other end was in bad shape.  Total repair was $800.  

I decided to send the car to my mechanic to fix the ball & Socket issue as I live in a condo I don't have garage space to do the repairs.   

Thank goodness for AAA as is no cost to send the car to the mechanic via flatbed.

Does anyone want to hazard a guess what the mechanic bill will be?

Thanks for the heads up.,   I will let you know how it all turns out.

Thanks JFP - A couple of quick additional questions:

1. Is there a way to look under the car to see if indeed this is the problem, or do I need to pull/drop something?
2. Is installing the new snap on ball joint a minor job or would you recommend taking to my local mechanic
3. Is this the part that I would most likely need?

      Shift Linkage - 1998 Porsche 911 Carrera Convertible

Hi JFP - Thanks for the reply, that makes sense based on how the transmission feels.   However, upon further investigation,  I thought that the 993s had shift rods, not cables?    It is a 1998 993 if that helps?

I have a 1998 Carrera Manual Transmission Cabriolet with 22K miles that I have owned for the past year.   Been a fantastic car with no issues up until yesterday.  Just took it out for a two hour highway run on Sunday morning.   As I was reversing the car into my parking spot, I heard a metallic noise (not unusually loud, as the transmission does have a mechanical sound to it - in which I do love).   

From that moment on, it felt as if there was no connection to the transmission (cannot feel the H pattern).   The car is stuck in Neutral and I am not able to put it into or find any gears.   I turned it off and started it - but the same problem.   The transmission feels the same with the car off as it does when it is on.   The clutch feels the same as it always has.

Any ideas of what I am dealing with here?

Thanks for the update.   Will see if I can purchase on eBay, if not will just wait until the manual arrives with the 993 :)

Does anyone have access to a PDF of the official owners manual?

I just bought a 1998 Carrera Cabriolet and would like to do some studying up on it before I get it delivered in January.

Thanks - Steve

I am in the process of buying a late 993 Cabriolet to replace my current 2004 996 Cabriolet.    I love my 996 but have decided to go a bit old school :)

I have found 1998 with 46K miles based in Colorado Springs.    

Prior to purchasing, I would like to have an independent Porsche mechanic take a detailed look at it to see if there are any issues/drama with the car.   

Does anyone have any recommendations for such a person/garage in the  Colorado Springs?  

Any help would be appreciated.

I have found a 1998 with 46K miles that is currently being driven from SF to LA this week.     I have attached the CarFax and the factory option packs as attachments below (Thanks to Loren for sending to me!!)

We have an '04 C4S cab with factory installed PSE.  I modified the relay (using the instructions another forum member posted years ago) so that PSE is default on.  I rarely turn it off (top down or top up) unless I'm leaving the house super early in the morning so as not to disturb the neighbors.

 

Just love that sweet music coming from behind us, especially above 3000 rpm, and especially with the top down.

 

Is it too loud?  I would say 98% of the time, no.  I'm under the impression most of the aftermarket systems are louder.  I've been asked many times by other 911 owners what aftermarket system I have as they seem to like what they are hearing and don't realize it's an OEM system.

 

Thanks for the reply!!   I am heavily leaning to getting it done (assuming I can find someone local who I trust to do it).

My brother (who is the mechanic in the family)  sent me the following video of a person in the UK who converted his 996 stock exhaust with a bypass from the inlet to the outlet pipes.    It claims that it is what Porsche has done with the sports exhaust option that was available on the 996 (though with the Porsche option you can turn it off/on)

https://www.yahoo.com/news/simple-exhaust-modification-gives-996-212015583.html

I have a 2004 911 Cabriolet and was thinking of doing the mod to my car, though I am a bit concerned that it may be a bit too loud.   As I live in Florida, I try to drive with the top down as much as possible.

Two quick questions to the forum:

1. Does anyone have any personal experience with the sports exhaust option on their cabriolet?   Specifically do you keep it turned on/off most of the time and does it depend on whether you have drive with the top up/down?
2. Anyone done the hack in the video and are there any gotchas I need to be aware of?

I appreciate any feedback.

I just got my book from Amazon on Wednesday of this week. Since I am Amazon Prime I get shipments in two days, so if you are not prime expect yours to arrive any day now.

Just looked at it briefly and am very impressed with what I have read so far!!

Thanks for all the advice, I dropped the car off at my local mechanic (along with a printout of all your suggestions). pugs2bb you were correct, upon further testing on the ABS unit he found another broken booster line.

Not sure why they are going bad, maybe the hot weather here in Miami or perhaps my coolant pipes blew about a year ago so not sure if that may have done any damage to the hoses or not.

Any suggestions besides old age - I just turned 53 last week so I guess the joke is on me :)

Will work on the other codes later but at least it got my ex of my back for the next 72 hours :)

Was away for the holidays and when I got back to MIami, the Ex told me that her 2004 CTT with 84K miles on it had a number of warning lights on the dash. So I got out my trusty Durametric kit, attached it to the PC and pulled the codes. For some background, we are looking to keep it for probably another year or two unless it starts getting crazy expensive with the repairs (we have had it for six years). So really just concerned about issues that will cause short/medium term problems and or safety related issues.

It is her daily driver which is mostly just city driving with 1-2 road trips a year. I just installed a new battery (many thanks for whoever posted the information on how to change it) so am pretty sure not a battery issue causing the rash of codes.

Any help with what the codes below would be greatly appreciated.

P0441
Evaporative Emission System
Incorrect Purge Flow

P0234
Turbo/Super Charger Overboost
Condition

P1914

Brake booster pressure sensor

P2189
System at Idle Bank 2

P2187
System at Idle Bank 1

1276

PSM - Hydraulic pump

Thanks for posting the details of the upgrade!

roadsession - Thanks so much for the advice. Just got back from my road trip on the 25th to NYC and back. A couple of observations on my trip:

• I took Florida Turnpike/75/85 and just a bit of 95 from outside of Richmond to NYC. Stayed off of 95 as much as possible which was easy since I broke up the trip by staying in Atlanta with friends.
• The time of day/night you travel makes all the difference. TIming so you stay away from rush hour while going through major cities is key.
• Florida as the best public rest areas.
• When I was in college, you had to make sure when driving at night that gas stations were open. That is not the case anymore, you can always find gas and places to eat no matter the time of day..
• Cops were only bad on the last segment of my trip from Atlanta to Orlando to Miami. The rest of the way was smooth sailing.
• Typically drove around 85-100mph. Gas mileage was about 23 mpg
• Wow was it cold this trip. Especially in NYC the week after New Years.
• Parking a 911 cabriolet on the streets of NYC overnight is no problem. I parked my car there for almost three weeks (alternate side of the street was suspended half the time due to snow/cold) and no issue.
• Maryland is the worse state for people not getting out of the left lane. Florida is a close second. Lots of people get pissed when you pass them going 100 mph after giving them a quick flick of the high beams while approaching. I figured it was like a European vacation for them as it was like they were driving the Autobahn/Autostrata :)
• Gas is super cheap in South Carolina.
• Waffle House in the deep south is a cultural experience that one has to partake on a semi-annual basis. Plus they all have internet juke boxes so you can make friends with the locals by playing a Tom Petty song and the TLC song "Creep".
• You see very few high end cars on the highway. I can count on one hand the number of Porsche's I saw while driving the entire trip.
• My Valentine unit was throwing a ton of false positives. I guess that it is due to the traffic sensors that are getting installed on most major interstates. I really need to upgrade my unit
• Spotify is fantastic for long trips. I bought the new Bose i20 in the ear noise reducing headphones and used them on my ipad while also running Waze in the background along with Google maps. Saved my *** a number of times with traffic and cops shooting radar.
• I used my summer Continental tires for the trip which was probably not a smart idea, however I missed all the snow/ice while driving. I ended up having to put about 5-6 psi in all the tires after the first half of the trip. I guess I attribute it to the cold.
• There are some serious pot holes in the northeast, fortunately I missed the vast majority of them :)
• My dogs were amazing the entire trip. They slept in the passenger footwell the entire time when driving and were a big hit no matter where I took them.

In summary, I would do the trip again. Was a blast driving at night listening to music all in the comfort/performance of the best engineered car in the world.

I decided to make a road trip from MIami to NYC with stops along the way this holiday season in my 2004 Cabriolet (BLack/BLack with 43K miles). Going to pack my cold weather clothes, put the two English Staffys in the passenger footwell (see enclosed picture), fire up the Valentine along with Google maps and head north on Boxing Day then back down again in mid January.

Are there any cold weather pre-trip maintenance that I should be thinking of? I am going to be visiting my brother in Baltimore where we are going to put on new brake pads and change the oil (having an brother with practical mechanical instincts is a blessing when one owns older German cars), so we can do some of the stuff there, otherwise I can have my mechanic do it for me prior to my trip.

Any advice/insight would be appreciated.

I will send some pictures along the way. The two Staffys have service dog tags so I am sure that there will be some memorable moments along the way.

Hope you all have a great holiday!!

Tim- I went to my mechanic today to put the new hose in, he started taking apart the hose and then told me to wait a minute. He came back wtih some hose from the back, he cut it to length and installed it. Brake Booster problem went away.

I asked him what I owed him, he shook my hand and said that it was on the house.

I am thinking it was either good karma and/or the holiday, either way I am taking it :)

Thanks for the post. I had the same brake booster alert with my 2004 CTT with 85K miles. Low and behold the same hose was cracked at the lower base, I just ordered one from Sunset Motors for $85 (love those guys).

I am looking forward to not seeing that warning alert anymore as well as my ex-wife no longer threatening to take the car to the local Porsche dealership to fix it :)

No, thank you very much!!!

I just got a brake booster failure waring on my 2004CTT.

Has anyone every gotten that warning before?

seeing as it's a tradiational vacuum booster the only falure I can think of is vacuum leaking or a diaphram failure. braking BTW seems fine no issue with power brakes.

any ideas and thoughts are welcome, thanks
