Porsche Warranty OPC Woes and Advice - Page 1 - Porsche General - PistonHeads UK

Any advice from the sage old heads on how to approach this conundrum would be great... I have a Panamera 971 4S. It is seven years old, and extremely cherished, with a full Porsche service history and ongoing extended Porsche warranty and not a mark on the body work. I have had an amber engine warning light on the car appearing for the last 18 months. It has been with my local OPC THREE times now over the last 18 months, and they have done various bits and pieces, but the engine light keeps returning within a few days of receiving it back; they have changed various sensors, I have had a full service, and I have just had the car in with OPC under warranty for the last five weeks as and they changed the cooling fan and felt they'd got to the bottom of the problem... until three days later the light returns. I have asked whether the timing chain needs changing as I can possibly hear a slight rattle, but they felt this would not explain the amber engine warning light. The light doesn't seem to impact driving, but I would like to sell the car and understandably no-one wants to buy the car with this light flashing. What would you do? I'm at a loss at how to approach this moving forwards so they can get to the bottom of it.

Perhaps try anonther OPC, this one seems out of their depth. Surely they must have a clue based upon the error code(s). Have thy ever told what the 'suspected' cause is each time or is it the same issue they are chasing time ant time again. Get a code reader and post here. Perhaps others have experienced similar and the fix is know here or in the Internet. Edited by churchie2856 on Friday 11th July 16:56

My Cayenne V8 S diesel (late 2016 reg) had similar issues - in and out of OPC after an initial issue with an issue with adblue and then 2 faulty injectors-an engine drop out job to replace. I was in loan cars for about 5-6 months in total after repeated “fixes” which then failed after a week or so. The engine light would come on but car was drivable. Car must have been in >6 separate times. Each time another part/sensor replaced under warranty. Eventually after much involvement and tech queries referred to Porsche the OPC did get a resolution and car is now A-ok. I got the feeling that it eventually became a matter of embarrassment for them and they went out of their way to make sure eventually it was resolved. It was very frustrating and I certainly did consider selling or using another OPC but I definitely got the impression that they were working to get it resolved with pressure perhaps from Porsche UK and from extended warranty. (Which I will definitely extend!)

What fuel are you using? My old man had this with his, he stopped using Sainsburys fuel and the EML went out. One tank of Sainsburys and it came back on again. It is fine driving around town, but the minute you get out of town and put your foot down the light would come on. Probably not that, but thought I would mention it, just in case.

If you don’t know what the associated diagnostic trouble codes (DTC) are, you’ll continue to be in the dark and waste your time at the dealers. Shops do not have the time to trouble shoot cars with finicky issues - they’ll throw parts at it in order to get it off the ramp for a car needing an oil service at £400 a pop. Get a code reader and investigate yourself and guide the shop, saving both you and them time.

With knowledge of manufacturer warranty procedures, firing the random parts cannon at a car is precisely not what they do. If a car returns within a certain timeframe with the same fault, the previous claim is scrutinised and potentially rejected, and another specific process has to be followed (usually raising a case with the manufacturer technical department). (Granted some dealers aren t great at problem solving!)

Mine was caused by a perished rubber seal on the fuel cap. Though this should show up on the reader. Worth checking yours. A simple, cheap fix. Probably no help but...

Edited by churchie2856 on Friday 11th July 16:56 That is what I did with my Macan when my closest OPC failed to fix it after 5 breakdowns. The original supplying OPC took it and fixed it.
