What’s the problem with my Volvo V70 TDI Bj. 98 with automatic gearboxes occurred some time ago: When the engine is running, the engine suddenly dies off. After that, it can start again without problems, sometimes it only goes out once or twice, but lately the problem repeats itself during the whole drive. It is striking that the engine does not produce the problem after the cold start during the first 10 minutes, but only when it is really warm. Also, the whole thing announces itself shortly before, when the rotary zalometer starts to spin, i.e. the needle goes quite whirling up and down. After the death of the engine also the control light remains on. Then I went to the Volvo workshop. After reading out of the fault memory had been found there that the speed sensor was defective. The part was replaced, however, at the result nothing changed: 10 minutes after the workshop left the engine, then all the engine went out again. After a further workshop visit, I then analyzed the cable tree, but without any result. In short, I then found a Volvo that was less connected to the engine, gear and related to the engine and the engine. In the engine, but then the engine was again.
