has the following problem: when the car is still relatively cold it often happens, which in the first and second course between 2000 and 3000It suddenly opens the popoff and is blown off charging pressure. at the moment before it feels as if it is building too much pressure, means: although only minimal gas is given, it seems to build up quite a lot of pressure and blow off this abruptly.. what can it be about? N75, n249, Wastegate? don’t know exactly where I am with the troubleshooting a The Lmm has a light hood.
