Hello, would like to start a new thread again, following on from the existing one: https://www.motor-talk.de/…/…est-not-complete-t6901261.html?… Could be interesting and helpful for some others with similar problems, regarding diagnostics of the friendly. Was now with the friendly one today, among other things, the problem that the tailgate of my SL500 R230 does not pull itself completely (up to about 1 cm). He said that it was no problem, is probably somewhere leaking in the Vak uumsystem. After some time he called me and said directly that the vacuum pump was broken, replacement necessary for 1000€ net. Had I absolutely not expected, for the following reasons: – All other mechanisms controlled by the vacuum pump (ZV locking and locking of all lockers inside) work perfectly. – The well-known “trick”, battery to/from and/or fuse out/pure works, then the tailgate closes completely, but only for 1-2 times) – One Hissing/air noise can be heard when opening/closing the tailgate in the tailgate lock. Therefore, hold a broken vacuum pump for excluded, instead rather a leak somewhere in the pipes or even directly in the lock. I also told the friendly one, whereupon he became somewhat unfriendly. How do you see this?
