E70 3.0D cutting out

Post by Leslie » Tue Jun 17, 2025 8:23 pm

Well got a similar issue today in my SD, round the roundabout and mine went with a bump into neutral and glided to a half luckily there was a little space on the dual carriagaeway to pull in . Pushed the start button it spun over but didn't fire , left it a minute and took key out and back in and we are away again. :rofl:
Got home and put foxwell 530 scantool on and we have many codes ( a lot of which I know off but care not for :rofl: ) but injector 5 activation stands out . To make matters worse I remembered I had millars diesel sport fuel additive in the boot so threw 50 ml in but guess what . It wasn't :fuelfire: It was Millars vspe ethanol lead fuel treatment for classic cars which has an identical bottle that I brought back for my xr2 :headbang: I then went and got £20 of diesel and drove it on , did 130 miles and its been fine so far but I suspect the cat wont be keen on it .
One of those days in too big a hurry .
I was able to check the injector smooth running after and they are all mint all close to zero so its more an electrical issue possible due to it sitting a month on a steep sloping drive nose up and water has been getting in the injectors which they are famous for . After only just paying £430 in ved I feel a bit miffed as I only put it back on the road as the Passat failed mot :rofl:

Ooops, Seems familiar just like the problem I had earlier this year, if it is then the cutout will get more frequent as the injector piezo fails when it does no start at all. Replacement injector time
