Hi Guys,
In my Audi A6 (2.7 TDI) i am getting the yellow engine warning light. i was able to read the fault code and the OBD shows P2020 (no other additional codes). But i don't see any difference in the car performance. I checked with the local dealer and he quoted 1500 Euros (mainly to replaces the left and right suction valves). I have to anyway check with Audi Workshop to reconfirm the problem.

My question is if ignore this warning light and drive, will it make any safety issues or will it create more repair costs in future.

Why i am asking is i have also other inspection and one more repair of axel correction is pending. Altogether it will cost 3000 Euros for me. But the current vehicle value i guess is only 7000 Euros. So thinking whether is it worth to do these repairs.


Thanks for your advice.
