Afternoon guys, Looking for some help really some of you may have been following other forums with this issue listed but though id try directly on here and having limited or no success. Were to start car specs: 2007 Z4M Imola Red interior Black Exterior 19" alloys 15,000 miles The issues: Car accelerates fine under soft touch of the throttle, however when planting your foot it hesitates fluffs and dumps engine into limp mode ish like 1200 rpm hunting, turn off and restart and clears all faults and is fine again!! I have had it on a rolling road and all emissions are fine, fuel mixtures, injectors oxygen probes, MAF fuel filter, fuel pressure etc etc etc. It has been in MAD and BMW now for three weeks and three weeks and no one can find anything wrong with the car besides they know that the fault is there and dangerous. The car apparently has had a small accident at some time in its life which is not unusual for most cars nowadays, but they have spent 23hrs and cannot find the issue and as they suspect the car may have had a repair at some point they will not uphold the warranty even though the car has been fine previously so it has just developed this issue. And now want me to pay for there time before they will go any further even though they do not know if it is warranty or not!!! Some one please help I am not made of money and love to car but need help. Thanks Nick
