Rather than disturbing everything removing the tank, would have been easier to purge the in tank pump via VCDS, yes you won’t get 100% of the petrol out, but if you brim it with diesel won’t do any harm, save all the hassle

That was a lot of unnecessary work. Pull the fuel out through the filter, once empty replace the filter and then put a few gallons of diesel in and prime it with new fuel. Then fill it fully with diesel and you’ll be ok. Did it last week and it works a treat.

I had a miss-fuel on my A3 p8. Drove it home, took the back seats out and siphoned the fuel out from the pump access. Brimmed it with diesel and never had a problem other than having 40 litres of petro/diesel mix to get rid of and all the fuel I spilt when removing the pump.

hopefully the life of the hp pump and injectors haven't been shortened, otherwise score.

FYI vw sell a fuel adative get some of that in it to help lube the HPP and injectors !  May stop them from failing in the future

You probably covered this off camera but with all of that unburned petrol in the oil, a change of oil and filter may be considered.

I filled an ASDA home delivery sprinter van to the top full of petrol after an 8 hour shift.  Never owned a diesel and just picked up the wrong nozzle.  Managed to drive it the store before it began to stutter, and then it dawned on me what I had done. It was repaired within a few days, but my reputation lived on for several months.

The petrol you drained works brilliantly in a chainsaw.

Give it a few hundreds miles and if the high pressure pump will be ok, you get lucky. Petrol could make a serious wear on hpp and it could shows up lately. I hope that it will be good.

DEAN this is 100% true  i drove manchester to glasgow in a transit years ago then deliverd and then fueld up at 3AM with petrol full tank .   and it was a  diesel van  i started it and sat there eating a pastie  and crisps then it died  ,So i cut the pipe off the jet wash machine stuck it in the tank and sucked and i swear it started coming out all over the grid and grass ,Then i   ree  filled it with diesel ,it started but  it wouldnt do over 50mph in 3rd untill  i got to preston then boom it went normal ,i parked it in our yard at 9am and went home never heard again .

I have a T6 and the forums say the engine I have is prone to leave the chat early, so with all your VAG experience I thought it might be cool if you replaced it with a petrol TSFI engine of some sort. It would make great content, receive loads of views and give me one impressively quick Kombi.

When I had this petrol put in a Diesel car, the RAC just connected a vacuum pump to the fuel line into the engine leaving the fuel cap open of course, changed the filter. Job done.

Usually petrol will severely damage a diesel pump because the diesel pump relies on the diesel as a lubricant as well, petrol has no lubricating qualities so the pump runs dry.

As a cab driver for many years, when it got really cold. I use to put half a gallon of petrol in to stop the diesel freezing

Dean, you can run the fuel pump using VCDS to purge the fuel system.

Half filled my 2.2 transit with petrol before i realised. Toppes it up with diesel and apart from smoking it ran lovely.

You’re a braver man, than me Tonto. I’m not sure I would’ve pumped petrol with that oil evacuation pump. But hey, you’ve shown us it didn’t burst into flames 😂😂

I bought a 2003 Polo PD TDi brand new & mis-fuelled it when it was about 2 weeks old, had it drained down & refilled with diesel & ran fine, this car is still my daily driver & now at 20+ years old & with 226,000 miles coverereed since I guess the mis-fueling didnt cause it any long term issues 🤣

Man I love your channel! Quality repairs and content, no bulls*** straight to the point being a mechanic myself something I would consider doing when I have the money
