weslangdon Posted September 24, 2017 Report Share Posted September 24, 2017 my son has put about 12 litres of petrol into his tdi Arosa, leaving it about half full, realising his mistake he returned to the petrol station and filled it to the brim with taxi fuel, should he have it drained or might he get away with it Quote Link to comment Share on other sites More sharing options...
Pete Posted September 24, 2017 Report Share Posted September 24, 2017 He should’ve drained it. Has he driven it since? Quote Link to comment Share on other sites More sharing options...
weslangdon Posted September 24, 2017 Author Report Share Posted September 24, 2017 Yes, had trouble starting it after filling it up with diesel but since then he's driven home, I'd guesstimate the tank has 2/3-3/4 diesel in it which is way above the 5% that the rescue companies indicate to be manageable. He says once started it was running normally with no misfires but from what I've read the risk is to the diesel pump rather than the engine as such, anyone else done this and got away with it?

Sausage Posted September 24, 2017 Report Share Posted September 24, 2017 i think i'd be looking at siphoning at least half that mix back out and brimming it with diesel again to get the dilution to better levels. The mix you take out can then be used next tank full. TDI have PD injectors so i'd be trying not to **** with them if poss. Quote Link to comment Share on other sites More sharing options...
