Tack, Tack and my trouble sends greetings

Hello dear Volvo friends, it’s enough for me now! Now I have only 3,700 km on the speedometer and come for the 4th time not from the spot!!! I was 3 times in the workshop because of the well-known “tack” problem when starting. Starters have been changed, cables have been checked, electronics checked. And now I’m standing again and I don’t get the engine to run!!! In my opinion this is pretty slowly unacceptable, I’ve been about all 3 weeks in the factory and the problem comes up again and again. a car is still there to drive, or am I wrong?! I don’t want to say here that the S40 is a bad car, by no means, but MEIN S40 has clearly serious problems! Does jmd have an idea what I could have left of my still changing so that I can finally start my car without worry in the early morning and can also make a quiet trip abroad? lg dominik
