"The amazing thing - the car ran two 45 minute races without going into 'limp home' mode!!! "
Has "limp home mode" been an issue under any circumstances? (i.e. more time on the track, hotter days, etc.)
My understanding is a stock 135i with its extra oil cooler is doing fine being pushed hard at the track unlike its predecessor the 335i?
I think I have read a couple of threads where a 135i has had some issue once software was added though.
To all readers, is this conclusion correct?
