Hi there , I have a 2000 Audi all road Diesel that keeps just stopping, when driving my Allroad just stops ! it appears to just die , there seems to be no commonality with the issue. The car drives perfectly and then it appears fuel just stops getting to the engine , the aa have rescued me twice and my garage have had it for 2 weeks, the issue is that there are no fault codes displayed, thus far we have changed the crank sensor but its has made no difference, any help would be greatly appreciated.
