The engine check light on my Cayenne came on a couple of weeks ago and is now continuously on when I am driving the car. I have booked my car into a Porsche Indy for an OBD check this week to see what the fault code is and hopefully they will resolve the problem. When I contacted the OPD and the Porsche Indy both explained it was most likely to be an emissions issue, probably the DPF and that I should go on a long drive in manual gear change mode and to keep the revs over 2,500 rpm. I have since been on a few long drives, no change in performance or mpg and the car drives as it had done previously before the engine check light came on. My question really, is if it had been the DPF then the warning light specific to this would have appeared also ? if anyone has had similar issues I would appreciate to hear what the problem was and approximate costs to resolve the matter.

Hi
I have owned two Cayennes one from 2013 to 2019 a 3.0 litre diesel covering 85k miles never had a engine warning light come on.
My Second Cayenne from 2019 till present a 4.2 Cayenne S diesel and after about a year had the DPF warning light come on tried the driving for 10 minutes with revs above 2000rpm But car went to limp mode and had to be recovered. My OPC done a regeneration of the DPF free as car was under warranty.
Since then I drive the car mainly in Sport mode and every week do the 10/15 minute drive in manual with revs above 2000rpm and have had an occasional DPF light come but disappears after the manual drive
I agree with you , a DPF warning light should have come on rather than the Engine warning light. When I got the DPF warning light there was no Engine warning light followed. I believe aDPF regeneration outside of warranty would cost in excess of £1000.
My second Cayenne has had several problems, Transfer Case failure, DPF problems and lately Adblue problems leaving me very unimpressed.
I think you need to get a fault code as driving with Engine warning light on in not ideal .

Hi, Interesting to read your comments about the issues you have had with your Cayennes, especially your current 4.2S diesel. I took my Cayenne in to Ninemeister (Porsche Indy)today for them to do an engine management light diagnostic test, fit a new rear door lock and an MOT. The diagnostic fault was caused by the wiring from the catalytic converter to the connecting block which was caked in mud. After they cleaned the connections they reset and cleared the engine management light, did a test drive and the light stayed off. Needless to say it passed its MOT with no advisories. I now think it’s a case of hoping the engine light doesn’t come back on.
Hi, The engine management light has come back on again, so I did an OBD check yesterday with an iCarsoft POR V2.0 and the fault codes P2201 and P20EE appeared on the screen. These relate to a NOx Sensor Circuit Range/Performance Bank 1 sensor 1.
I was wondering if any Cayenne Diesel owners have had the same problem and would appreciate any comments on whether this is a case of just replacing the relevant sensor, approx cost etc…
The car has done 68k miles, is running fine, no difference in mpg
Thanks for any comments please.

Prior to a two month trip to Europe I had the 2009 V6 GTS Caynne serviced. Shortly after the car went in to limp mode with the engine warning light on permanently and the glow plug light flashing. I popped in some Dpf cleaner and did a re-gen and took it back to the Porsche independent in Trowbridge.
I was told they would have done the same and if there was a problem with the car it would produce a fault code.
In Italy the car got worse and we limped to Greece. Everything pointed to a blocked DPF FILTER but with 4 on the car the cost to remove them and have them flushed was high. I decided to investigate this is what I found:
An old water leak from the temp sensor had corroded a connector
the Turbo inlet was barely secured by one screw and was caked in oil and dirt. This was cleaned and refitted.
The left hand intake linkage was hanging loose from part number number 710131.010 (£150)
I got a local garage to order this part along with the DPF pressure sensor Bosch 0281 006 005 (£45)
These were fitted in a few hours at a cost of £80 and touch wood the car has performed exceptionally for 5 days now. By the end the car was in limp home mode every day so I think we may have solved it.
The DPF warning is activated by sensors and often it points to another component failing. Provided you use decent fuel and do a decent run now and then it should re-gen with out you knowing.
Hope this helps
