Hi all I have an annoying on-going issue with my 2003 ML320 petrol. 50K miles. FSH. Cossetted. Symptons: Cold starting. Starts on the button (key) but when pulling off loses 50% power. If I let warm up for two minutes it runs perfectly. Warm starting. Sometimes cuts out totally needing 1/2/3 restarts. Can be hesitant for first 50 yards. In both cases, within 200 yards OK for rest of journey, be it long or short. Whats been done: Has been two three garages; firstly my local, then a specialist MB alternative garage staffed by ex MB employess and finally MB dealership. Each outlet voices the same opinions, mostly based on a computer but also their expereince. I kid you not when I say I have had the following items changes three times ... Plugs - they all have their own chosen "one" Leads - see above Coils - running out of ideas Lamda sensor - see above TDC sensor - see above. There is some considerable cost to these items. I've had enough. The fault is there 50% of the time. It was there when I visited the garagtes in question. I have no problems with these garages I just want the car engine resolved. Ideas please.
