Desperately trying to identify a common denominator which links performance of engine, exhaust sound, smoothness of power steering, braking performance.
I get varying levels of performance from my TFSI quattro (BWE engine). At times it feels quite lethargic where the engine struggles to breath, exhaust note is louder, power steering is heavy and braking performance lacks. At other times I get fantastic performance from all the above and it feels like car completely different car to drive.
The performance seems to improve after the car is driven and then left idle for 5 or so mins or if switched off and left standing and then re-started.
A lot has been spent on the car as I plan to keep hold of it for a while - please see signature for mods etc.
Just wondering if the issue is related to a sensor i.e. map sensor or 02 sensor etc. Would a fault display in the dash if these were on the way out etc?
Any help or some pointers in the right direction will be appreciated.
Thanks
