New Owner Question?

[AshR]

Hi All,

Following my first post a while back and some great advice from the members on here, I have managed to pick up my first Porsche; a 996 911 Carrera 2 Tiptronic S. It is a 98' with a brand new Engine fitted by PCT back in 2004. and FSH with invoices for work back to almost new dates. It has 70K on the clock with all the extra's including Becker Sat Nav, AC, heated seats, tracker, sunroof all working as new.

Mechanically it generally feels really sound and the body is immaculate.

I have however one concern which has come to light after owning it a couple of months. In full automatic mode, the car can on occasion seems to limit the revs for about a second when it shifts from 4th to 5th gear but then is fine through all other gears. If I apply the revs slowly it doesn't do this.

It is also fine in Tiptronic mode through all gears regardless of Revs and shifts quickly and smoothly on button push.

I am taking it to my local specialist for review but wandered if anybody has experienced this one before so I can have some kind of idea of the potential issue first of all before undoubtedly having to spend out on it.

Could it be a TC issue or hopefully my biggest fear is a gearbox/clutch problem....

Any ideas or thoughts would be appreciated.

Cheers,
Ash

Seems like this thread is similar except happening in Tip mode not full auto like mine. Seems to have drawn a blank...

I'd venture fuel or mixture issues - check the sensor from the previous thread.

Also (uncommon) a glitch in the EMU I wonder - might be worth a remap to see if it clears the problem - grasping a bit but that's what I'd try - OPC can advise, or a remap specialist.

Good luck.

...and check the MAF as we'll.

Hi,

Are you saying that your hitting the Rev limiter and the cars shutting down?.

If so that correct.

Is your car throwing a CEL? and have you read for any codes?.

 

[AshR]

Thanks for the responses so far, I'm nowhere near the rev limiter when it occurs but it seems to have the same effect as what happens when you do that in a car.

Strangely, just took it on a 20 mile round drive and it didn't do it at all today was smooth as ever...

There are no error lights displayed at all on the dash, not even temporarily when the fault occurs. I called my local OPC here in East Northants but they had no techs working weekends. Gonna book it in for a diagnostic next week to see if any error codes are logged.

I did get stuck having to put standard unleaded in it as it was all the petrol station had last time I filled up so maybe that caused some of the problem. If no errors are found, I'll get the Gearbox oil changed regardless as it is roughly 1000 miles since last oil service according to invoices etc so probably a good time to get all lubes done etc anyhow.

hopefully you mean more than 1000 since last service

REmember when you change the oil in the gearbox only about 50% is changed unless you flush

Bit expensive bt worth it

Any news on this

Did you change the gearbox oil

Maybe if yuve always run on super petrol this caused the problem

Buying from a supermarket is not always a god thing - although I understand Morrisons in Shell
