Apologies for my first post being a request for help but I have been a lurker for a while and an A8 parts customer
I have a 2005 A8 4.2 TDI, circa 125K miles on the clock and it has just started showing an amber engine warning light, I have checked with VCDS and the following error is showing. Clear the code, the light goes out for a day or so and then returns.

Google suggests that I need to replace G450 or possibly G451 sensor? Has anyone come across this before or can you give me any tips? Is the part something that is best from a dealer or elsewhere and where will I find the sensor on an 8?
Thanks in advance
