Hello people hette so far often the start problem known from the v40 and wanted to have some new spark plugs installed. so I bought from volvo and had them installed in ner werkstat, there the noticed that a lot of oil was missing and filled me right away 2.5 liters, jaaaa 2.5 liters, after, so now the mechanic changed 2 candles and then felt him 2 down, but well he made normal wetter and also built this one. then I started the dare and well he still starts Laughs only with much more exposure than before and he is so loud and runs very irregularly. on the way home I noticed that I can not drive faster than 40km/h because otherwise my car disintegrates. because something at the hech vibrated and ratterte so strong and so loud that I was afraid to give gas, whereby he also did not want to take my gas properly. so was not only a light rat, but I was really afraid to drive with the car and in between he went also 3- 4 times just so time out and really drove like a tracktor ( 30 -40 km/h) and besides it stank in the garage when I arrived extremely burned (after oil or gasoline). can someone tell me what to amuse me now?
