Well, skoda ocktavia 2008, diesel. A combination of borrowing a petrol car for a few weeks and an early morning blurry eyed start meant i put petrol in. Tank was a quarter full, put petrol in the three quarters. Drove approx 1km before realising . Car died and i’ve pulled over. Am i f * cked?

You need the tank draining and a professional look at the fuel pump and fuel injectors.

3/4s a tank of petrol and then driving it is potentially pretty disastrous, yes.

It’s likely died as petrol doesn’t burn properly in a diesel. You’ve burned the diesel in the fuel line and it’s stopped once it got to the mixed fuel. Best case is drain, clean and refill after recovery. Very worst is new engine. In between is filter, fuel pump, injectors and lines. You’ll probably be fine with the first one. It sounds like it stopped pretty quick.

Probably a lot maybe only a little. Sorry for your loss.

If it’s the PD engine you may be ok after flushing the fuel system.

If it’s the common rail diesel almost certainly destroyed the high pressure fuel pump and therefore entire fuel system. The pump is lubricated by the diesel. Any petrol in it and it munches its self sending metal flakes around the entire fuel system. Can’t be cleaned so you have to replace anything that has touched fuel eg. tank, lines, pumps, filter, injectors…….

Yeah, OH did that to her Scirocco. New fuel system needed. Thankfully she had misfueling cover on her insurance as it was a hefty bill.

It’s a 2,0TDI 4X4

Dang what a start to the weekend

Conversely my mother did that to her 2004 Rover 75 2.0 diesel (BMW engine?) Got five or six miles with it and then it stopped.
Drained and cleaned and it was fine for years afterwards.
.
I’ve only done it the other way, diesel in two petrol lawnmowers, cleaned up and they were fine. Easier job than a car though….

I did this to a 2.0ltr passat with the PD engine, fuel tank was drained and fuel filter changed and it was fine for the years after that I still had it. I think the petrol I put in cost more that the fix!

Call the AA/RAC, get them to drain it – be worth buying containers to put the petrol in as it’ll be fine for a petrol car – put a gallon of ‘waster’ per tank of fresh.

Then drive the Skoda and see how it goes.

Did it years ago with my wifes’ Freelander – no problems with that or my petrol BMW that got the ‘waste’.

I think whatever happens repair will most likely exceed the value of the vehicle. I had to have a new fuel system on my 2011 2.0 TDI CR VRS and it cost me nearly £2k (car was worth about £6 at the time). I think the PD engines are a little more resilient but can’t be sure. Also not sure what year they changed over from the PD to CR.
I guess if you’re handy on the spanners etc. then you may save some money on that.

I also once put petrol in a deisel Octavia while on holiday.
I then drove it about 10 miles back to the camp site where it stopped.

Had it towed to a garage who drained it and changed the fuel filter.
Did another 100000 miles in it after that without problems.
This was around 2012 and the car was only a couple of months old. Can’t remember what engine was in it.

This kicks my broken spoke nipple into touch.
I’ve only misfuelled once, in a Passat TDi. Luckily I realised while I was filling up so no damage done, apart from in my wallet.
More embarrassing was/still is, is that I owned a petrol station for 25 years.
Good luck OP.

Did this in a 2013 Alhambra, new fuel pump, filter and lines and all was good. Cost about £400

You *might* be ok. The 2008 was still being fitted with the PD engine, which suffers this kind of thing more gracefully/with less damage. CR engines came in a bit later, and as said above, need full-fat diesel for lubricating the fuel pump internals.

If its PD, full tank draining and flushing and a new fuel filter and proper priming would be the minimum needed. See if you can find a local VAG specialist and get it towed there.

Update, got it towed to a specialist garage. Draining, flushing etc plus a tank of fuel , so around 600 quid all in. I’m in sweden so everything is more expensive. They were super helpful and pretty sure of a happy outcome.  Hopefully i’ve got away with it. Feel like a right tool!

If it’s the PD engine you may be ok after flushing the fuel system.

I did similar with a 1.9 PD engine in a Transporter, but the other way around – quarter tank petrol, realised, swore, topped it up with three quarters diesel. I just kept driving it and topping it up. For the first few days it would overrun when I switched off the ignition, but that soon stopped. This was ten years and about 80,000 miles ago, it’s still fine.

Did same in 2.0l mondeo, except was nearly a tank full of petrol & pulled over as soon as it didn’t quite feel right – RAC drained and refuelled, right as rain with no further issues.
