Hello all,

i have a 2004 996 TT Cabriolet and the convertible top can't be opened or closed while the car is moving. 

I know that all late 996 cabrios (C4S cab and Turbo Cab included) had a setup tht allowed the driver to open and shut the top while moving up to 50 klm/h

Any idea as to why it doesn't work on my car ?

It works only with the car standing and the handbrake up as per the earlier models

Could it be that the previous owner had changed a relay or a top controller to an earlier version ?

Any ideas or suggestions are greatly aprreciated

on the other hand I believe that M97 engines as well as 997 3,6 engines are more durable than 996 engines due to their revised design

Hesitation - Stumble problem. UPDATE

As many many here and in other forums, we are experiencing the famous hesitation problem on two cars

Car 1) 997 carrera 2 6 speed no sport chrono

Stock except from cat by pass pipes

72.000klms 2005MY

Symptom:Hesitation in 2nd gear light throttle up to 2000rpm. Above that works great

Car 2) 997 carrera S 2007 MY 6speed

Sports catalysts

Headers

PSE

Symptom:Hesitation in 2nd gear light throttle up to 2000rpm. Above that works great

Car only has 34.000 klm

On the 997S we have tried the following

New coils, plugs, MAF, Throttle body. Tested with fuel cap open, as well as drove without MAF. Same issue everytime

Anyone has solved this ? Any updates or ideas ?

Thanks

Do you have the stock cats and headers to replace and test with? This would be my first troubleshooting step. If the stock system still hesitates you know it's not your add-ons.

Has the ECU been remapped? Is the behavior recent or chronic?

This may sound ridiculously simple, but every few months I begin to detect a slight hesitation in my 997, and I simply add a bottle of Techron fuel system cleaner and by the next tankful it is usually gone or significantly reduced. I suspect these vehciles are quite sensitive to any type of fuel system build up. Aside from that, you may also consider the possibility they have both been fed some poor or contaminated gas. Just a thought. Good luck.

I have tried and tested many types of super plus unleaded fuel. The problem is only at very low revs, above that (2000 rpm) the car is very fast

Just to complicate things more I'll also contribute to this thread.

I have installed the Cargraphic headers catalysts and rear silencers with amazing results

Excellent quality and clear performance gains

There is really only the oil level sender and the two wires that go to the cluster.

So, I would check the continuity of the two wires from the sender to the cluster.

Do these wires go directly to the instrument cluster ?

Could it be the instrument cluster ?

.

I have changed the oil level sender, but still no working...

I can't see how much oil s inside the engine.

Anyone faced this before ?

Any ideas of what is should look at ?

What does usually go wrong with these ?

Anyone has directions of procedure ? I think that there is more than current that needs to be wired.

Please suggest and advise

It was the contacts on the tip lever that were bad. We tightend them up a bit, and all is ok now. Strange thing is that the switch unit is made from Delphi. Weird if find this on a Porsche.

thanks for your help

Hello,

The reverse lights and park assist don't work suddenly on my 04 C4S TIPTRONIC.

Where is the sensor located ? Is it on the gearbox, or on the tiptronic lever ?

I checked the fuses and all seem well. Is there a relay I should check somewhere ?

What else should I check ?

PLEASE HELP URGENTLY

Well just to finish this thread off, I had the 24mm front and 19.6mm rear sway bars installed as per recommendation and I must admit the handling and lack of lean in corners is astonishing. Stock springs & shocks and still on 17" wheels and the ride quality has not been compromised. I highly recommend it.

Are the 986S M030 bars a direct bolt-on on all 986s ? (2.5, 2.7, and 3.2)

Hello all,

My 02 986S has some problem with the gearbox since yesterday. I get some grinding from 1st to 2nd, or 3rd to 2nd, especially when car is cold. I can't get second gear most of the times. The problem goes away when engine gets hot.

Is it a synchro issue ? Can this be repaired, or I need a new box ???

Hello,

we measured the gases on the coolant tank and these indicated a blown head gasket. Symptoms are that the car overheats after 20 minutes in hot weather. No leak anywhere.

So the question is do we change one or both head gskets ? Anyone done that before ?

Any tips ?

Hello all,

I am experiencing a problem with a mobile phone SIM card on a 03 CYN S PCM.

You install the card, an it displays the message "Synchronizing address book".

This can take ages, and in the end nothing happens. It doesn't read the names and numbers as it used to. The SIM card works perfectly on my mobile. What is wrong with it ?

TIA
