Hi, everybody, I always had the problem with my V70 (>40Tkm) that the car runs out very briefly during the ride. All lamps from the speedometer go on briefly, the ZV closes up and closes briefly and the car cracks very strongly. The car is usually warm in operation, drives on CNG and the accelerator pedal is only slightly operated (e.g. after gear change or after thrust operation). So I give as good as no gas. Radio runs on. Previously it was about 2 times a year and I found it no further Tragic. Had found something in a gas forum at that time that this affects many CNG vehicles. But there was no solution and the forum is offline. Meanwhile, however, it occurs every two days (approx. 200km) and becomes annoying and dangerous. Error code is not removed. Spark plugs are changed all 15-20Tkm, ignition coils are still the first ones. I cleaned thrush flap last year, but it was very clean. Could of course a cold soldering point on the cable or a Steue but have no idea where the cables of the CNG system are located. Or are there still hidden mass cables? I would be grateful for any idea. Such sporadic errors are annoying.
