Hi all,

2008 Cayenne, S 120km/75k miles.

It has been quite lumpy at startup lately, usually fine after a while but always the first few mins. I had the Coils done recently as the car was kind of 'skipping a beat' in the revs - so replaced all coils. Soon after it started getting lumpy at startup.

I used a very basic OBD2 scanner and Torque Pro to find the below fault codes. Could anyone shed some light on what this might be?



A quick google finds this: https://www.yourmechanic.com/article...-blake-griffin - just wondering if anyone has any specific Cayenne advice here? Is there anything I can try to clean first?

Also, while I'm here... Most days I get a loud beep with "Chasis System Faulty" error, I previously replaced two of the air shocks, but I'm still getting the error. However, no error codes on the OBD2 - and nothing from the garage on the last service either. Any ideas?

Thanks.

Just had this problem and it was a cracked crankcase breather hose. The crack was in the T joint at the rear of the engine so not visible. Made it so the computer could not adjust the mixture and it ran rich both sides.

Good luck!

Wow thanks. OK good to know. I'm sure that could have been easily missed and you could be replacing many sensors to no avail. Was it an easy/cheap fix?

The P2181 Cooling System Performance code is usually related to a thermostat stuck in the open position. A sign of a failing thermostat is that the temperature needle rarely hits mid mark on the temperature gauge.

I had this code over the winter months and replaced the thermostat and water pump this spring.
