Hello Opelaner, my beloved Omi needs attention again. The “problem” that I have had for a long time (actually always) sporadically is that with the mangelden performance. It lacks from the very bottom extreme of performance, the pronounced approaching weakness is more or less normal. If it runs “normal” then comes from about 1700 rpm slowly what and from about 2000 on it goes well. So again, it comes first gaarnix, starting like an ocean steamer. Also at 1700 and 20 00 is nothing. So at 2200 I have the feeling that the Turbo it langsaaam sometimes takes into consideration to build up pressure. Above it is actually possible. So 190 speedometers are easily inside on the level. (Until the temp rises however this is another topic and has got it so far in the grasp. Durable gas is still not in it but …. bla back to the topic!) In addition, I have been hearing vibrations between approx. 2500 and 3500 for a few weeks, only when accelerating. I would like to close out the turbo because it depends absolutely on the engine speed and thus also changes synchronously. Then I thought that it could come from the exhaust, I did not exclude it. Just on the ride came to me the frightening idea that it might be the control chain. So then also the power loss!? However, I have the noise already several weeks and the missing power only since yesterday, because he ran ever about half a year like ne 1! Oh yes, in summer 05 there was a new ESP, in spring last year 3 candles and now in December oil change. Hmm….., does someone come to know this ? For your help already in advance thank you!
