I posted several messages ago that I changed the solenoid (and the bracket). Didn't help.

 

did you pressure test the car correctly?
does it have a tune?
sorry I dont remember your details above...

 

multiple pressure tests, all good

car was tuned by Wendland back in 2002: K16 hybrids, exhaust + ecu tune @1.2bar

wastegates are stock and in good condition. Checked those as well.

 

that makes sense, on paper. but again, if the 02's are even suspect, i'd replace em as they parts that need changing periodically anyway, and as these age..?

i'm still stuck on the '02's,..sorry i don't know enough to know more. but I've had bad 02's, cracked coils, old plugs, and failing cam position sensors. every time, just replacing one or more of them cured my issues. but you've got umw kevin on your other thread, and markski helping here! so listen to them! and GL!

 

The O2 sensor was swapped side to side but the error indicates the wiring is swapped. I recall you having said you traced it but perhaps swap it just to see? These are secondary O2 for catalytic efficiency measurements, wear shouldn't be as big a deal I'd think...

 

If its one bank then you need to check the cam bracket and sensor if its broken on that bank.
