Mercedes A200 2.1 Engine issues
Discussion
Hi,
I have a 2015 A200D 2.1 Mercedes and it started to become sluggish including a misfire and struggled to idle but once warm seemed better but not perfect. After a few weeks it seemed to be getting worse and it would often stall at junctions. It eventually gave an engine light P0272 Cylinder 4 Contribution/Balance.
It went into a garage and they replaced Injector 4 and coded it, from the second I picked it up it wouldn't rev over 2500 then once I restarted the car it drove up the road but very lethargic. The garage said it would need a regen before things settled down and take it on a long run. I have since done several very long spirited runs and constant and when I got home the exhaust was pinging and was roasting hot which I though would be a good indication of a re-gen.
The light has come back on again now same fault code exactly, annoying after spending out what seems for nothing.
Any ideas or known issues that could cause this or I could check related to the fault P0272. I have a cheapo code reader than can get some engine data off and pretty handy with some spanners back in the day
Thanks
Neal

At a loss with this one now..Garage has done the following
Compression ok...
Injectors / seats replaced
Inlet manifold replaced flaps were blocked and not working with carbon, EGR cooler / Valve all cleaned up.
Still the same.....start the car you can not use the paddles, restart it again and then it runs rough at idle and throws an engine management light. Same code as before cylinder 4 inbalance. If you take it up the dual carriage way it has full power and runs fine.
Any one got any other idea I can try?
Kind Regards
