Hi to all Turbo-Profischrauber colleagues, have problems with my turbocharger at the moment and want to change the Wastegate valve setting.Unfortunately you can’t get there so easily.Can someone tell me if I come to it or if it is long when I unscrew the exhaust manifold at the block ???? I describe my problem sometimes, maybe one has already had this problem already. Car is not very powerful and only reaches the V-Max of 220 km/h (with a long start, straight distance, without wind).In addition, I have only a maximum charging pressure of 0.5bar. According to VW I should have max. 0.8bar. Have now renewed the LMM and the N75 valve. Result:Car pulls a little better, but still 0.5bar charging pressure. Did then the wastegate can with air pressure checked, full function. Then unfortunately, to see if the turbocharger is possibly defective,the wastegate can be cooled.Turbolader does not bring up to 1.5bar,so the problem has not been solved.
