Hi
I have a 2005 BMW 120d M-Sport with a very annoying random prob.
When driving at a constant throttle and coming up against a hill or over take the car seems to hesitate for a split second then it's ok.
I'm losing the love for my car and have spent £350 so far on trying to solve it.
Has anyone got any good ideas on where to look next
I've eliminated....
MAF, MAP sensor, IAT sensor, EGR solenoid, Injector leak back.
All OK.
It's not putting fault light on dash and only fault code stored is 4B90 which relates to fuel pressure at start up.
HELP ME !!
thanks
Ian
