Hi guys,

Maybe this issue already happened to someone with gen3 TFSI in my case Audi S1

I have errors P2088, P2090 and P0445 but nothing different with my car... no noise, no power loss!!

When I erase them after I start the engine again I have same error :S

Image attached

Any help is appreciated

I have further news on this topic!

the fuse F20 was not ok... replaced and the error is gone!

Tried the car for a few KM and the same problem happened again... now I am sure something it is something electrical.

Tomorrow I will check and keep you guys posted.

Check the wiring around the EVAP valve

Finally the problem is solved!

It was the wiring that controls the exhaust electronic flap that melted and was shorted.

You can see the pictures attached.

Thanks for support!
