Petrol in my golf - glow plug light ??

[Lauren123]

Ok cut a long story short £20 worth of petrol was put in my 59 plate gold 1.6tdi. Realised after like 2 min of driving and revs going funny cut the car out, drained the petrol, and refilled with diesel. Took it on a little run and all of a sudden glow plug light started flashing and it lost power.. i cut it out tryed restarting and didnt start. Waited five mins tryed again and it worked power was back. What do i do? Could it cause serious damage??

Yes i was driving it was driven for literally 2 minutes if that. And no dont think he drained the pipes

in my experience, petrol in a diesel just stops it from working till you drain it and refill with diesel

Maybe it depends on the system or the proportion of petrol and diesel left in the system. It's notorious for causing accelerated wear in the pump and then feeding metal debris from the pump through the rest of the fuel system, effective trashing the whole lot. Given the likely cost of that repair and the potential for making it much worse by driving it, I'd play safe if that was me. Of course it's always easy to be brave with somebody else's money.

What do i do then lol??

You may well also have stored fault codes too now even if the MIL as gone out this particlaur engine has an 02 sensor and 3 EGT sensors IIRC and if any of them are reading anything abnormal it will throw DTC's (fault codes) try not do it (petrol fill) again otherwise you may damage the DPF permanently

Please help changed fuel filter and now wont start gna go to garage
