Hello in the forum! As already mentioned above, I have had a new start problem when the vehicle has been standing for several weeks – he never had that in the last 7 years. Vehicle: G280CDI, WDB 461.3341X181642, engine 642.975 (OM642 DE 30 LA), LL = 186700 Km. I have the impression that the engine does not get a diesel at the beginning. After a longer start sometimes a cylinder ignites and at some point it starts and runs normally. If the vehicle is only standing overnight, it does not have the problem. I don’t know this engine and its fuel system yet and therefore the question about some tips where to start looking – error reading with the diamex shows me P 0123 – throttle valves – position sensor switch P 0030 – Lambdasondenheizung – control circuit P 1955 – he always had this error With best thanks in advance, Heinz.
