Help with fault codes - System too Rich

Zascar

Hi all, 2008 Porsche Cayenne, S 120km. 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/p0172-obd-ii-trouble-code-system-too-rich-bank-1-by-blake-griffin - just wondering if anyone has any specific Cayenne advice here? Is there anything I can try to clean first?

Thanks.

See can you check the coolant temperature or sensor, car could overfuel if it thinks it is cold.. is car reaching full temperature? Thermostat could be open all time

Yeah car temp is normal, right in the middle like it always is...
