On going issue, have ran out of ideas
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.

Are there any codes and check engine light showing up with these symptoms?
It sounds like you are not getting enough fuel pressure into fuel injector rail, if there are no codes present.
Did anyone check the fuel pressure for you.
Are all the plugs, leads, coils and oxygen sensors oem Bosch?
