moin, need some help, where I should start troubleshooting… The Volvo (see signature) has stood for about 10 days. Wet, damp weather, strong ground fog. When starting it ran a little rough, ABS and Tracs lights did not go out! After a kilometer stopped (put in a letter), then started again, ABS errors still there… After about 2km the engine went off! On restart he jumped briefly, but died immediately. After several further attempts and some waiting time e ADAC was there, tapped for errors in the ABS control unit. So plugs were pulled off, engine was running, no speed fluctuations, no speed fluctuations… Sound good, disconnected plug isolated, goes also provisional without ABS to home, so ADAC away… After about half an hour I also wanted to go… and came out 100m far! Engine! He died immediately after an immediate start attempt, after a little break he ran only slightly longer. So ADAC Called back… Started in the waiting time for a try…, he jumped immediately and ran impeccable in idle! Just let him run and wait a while, without touching the accelerator! He ran unreservedly warm, until the fan switched on… zack… engine off! So I have the impression, as soon as a (stronger?) consumer is switched on or gas is given, the error appears. ADAC then dragged me the short way home.. I cleared out the station wagon once in the back and the Re Then you can also hear the petrol pump running at “Züdung an” . Petrol pump relay 103 I actually had brand new in reserve , the exchange however also did not change anything … So where should I start with the troubleshooting?
