So I just got my car back from service (03 A4 1.8T APR93).
There was a failed o2 sensor , and some misfires.
On my way home , I notcied the car is not pulling as hard as usual. Im not sure if its because its hot out or what.
The sound of the turbo spooling doesnt seem to be as loud as I am use to.
what could this be ? Is it in my head or what ..

how hot out are we talking?

 

like 30 CELSIUS
Not 100% sure what the is in F ..

 

what really bothers me is that the turbo is not spooling loud at all, with APR on.

 

Better give the dealer a call then?

 

yea I guess so.. I really dont know what to think.
It still spools up , but not till 3500-4k rpm..
