    The last few weeks, when driving hard and exiting a corner the message "Indicator Failure" lights on the OBC and the oil pressure indicator goes to "0". After 1-2 secs the oil pressure returns to normal. I have checked the oil level and is ok. Searching in the manual the message on the OBC corresponds to failure to the oil pressure sensor. I am convinced that the problem I have been having is not related to an actual lubrication problem but rather to a problem to the sensor itself. May be a loose electrical connection on the sensor ? Can someone please advise me the whereabouts of this sensor ? Thanks Mat 911 40year Anniv.

    Yeah, the European flash ignores many of the sensors (as far as emission faults are concerned), where here in the US, we have all the bells and whistles. However, the US chips can be reflashed with the European program if you don't mind not being able to pass emission testing and can find someone willing to break federal law. I had P1123 and P1125 for quite a while, and since I switched my MAF it hasn't re-occurred. The fault was stored in the fault memory of the DME, and it showed the number of occurrences. You could read the faults with a PST2, but they did not show up on a scan tool. Because the "fault" was intermittent (it showed as something like 10 events per month) it wouldn't fail an annual UK emissions test. I suspect that Porsche consider that such faults would show up on a service visit, and could be rectified at that time. Mathew - where are you located? - you didn't say if it was a US or RoW car. I am located in Greece, that means my car is in the RoW category. Are the attachments you posted taken from PST2 ? Can I buy a scan tool to read the error codes P1123 & P1125 to do the job myself ?

    Thanks for the info guys, so in order to recapitulate, at least for Europian Porsches, CEL shall no be triggered if the MAF is "partly" deteriorated and not doing its job properly.... I think that's bad news, and is exactly what had happend with my TT... I can assure you I never had such problems with my Scooby.... Anyway how can I determine the health status of the MAF by using a diagnostic OBD software ? Can you tell by reading the g/s value of the MAF at idle at normal operating temp ? What should it read in order to ascertain the MAF is 100% OK ? Thanks

    rear tires are 285/30 18 (standard), that means I can you the figures you posted to determine actual speed (km/h per 1,000rpm) ? Are you sure 1st gear gives only 8km/h per 1,000rpm ? That means at redline (7,300) still can not reach 60km/h... I am sure 1st gear tops at around 65 km/h

    Anyone has the gear rations for the 40th Anniversary? specifically how many km/h per 1,000rpm for each gear ? Last night I hit 263km/h with 6th gear, tach reading arnd 6,100rpm. Wondering what was the actual speed ... Thanks Mathew

    Just wondering, is it possible to have a bad MAF without triggering CEL? My previous car was an AUDI TT and although the MAF wasn't working properly there was not any CEL triggered. The MAF wasnt totally busted but on the other hand it miscalculated the air mass going in the engine, the only way you could tell something was wrong was only by comparison to how the car used to fell before (stronger accelaration etc). As soon as a new MAF was fitted the car felt totally different again. The problem is that a MAF gradually deteriorates and there is any objective way to know for sure if it doing the job properly or not. Can I rest assure that in my Carrera if the MAF isn't 100% ok a cel light shall notify me and will save me from engine failure ? I think not since both Audi's and Prosche MAFs are made by Bosch...The CEL shall only warn you when the MAF has gone really bad. In simple words how can anyone verify that the MAF is 100% ?

    The one touch up or down function at passenger side window doesn't work. The window operates ok when you continuously press the button, but the one touch feature simple is not there.... Any suggestions ? Thanks Carrera 40th Anniversary

    Hi, I've read that X51 powerkit for the 996 in additional to many other parts, also includes a third radiator for uprated engine cooling... However my 40th Anniversary Carrera which has X51 as standard, does not have a third radiator. I would appreciate your comments ... Thanks
