Hello all

Just become owner of a gorgeous facelift M5 2001

93k miles and vanos replaced this year with bill to prove

Car drives great and have run the secret test to check mafs - all ok

I have the feeling though that carnie slightly lumpy below 2500 rpm. On full throttle it is a beast but seems a little unhappy at part throttle and low revs. Could be my imagination. Seems to be better if in sport mode

Does this sound like an 02 sensor or cps? I have read lots about these on the forums

Under hard acceleration it is a beast and pulls cleanly. It maybe I am just not used to the power delivery at low revs?

Why is it better with sport button pressed? Any views as to whether there is a problem or am I imagining it?!

Thank you!
