car running rough pretty sure petrol in it

[Leemus]

got a 306 hdi estate, fuel light was on so went and put £20 in. After about 800m the car started to drive lumpy, so i though maybe shit in the fuel so put my foot down and it cut out. engine light is on and just nursed it home about 2miles away. When i turn the key the fuel pump (think its that) is making a loudish humming sound if that helps. Although I'm fairly confident i didn't there is a possibility i put petrol in... but it wouldn't run would it? pretty sure i didn't as i haven't had a petrol car for about 8 years now. any help would be appreciated 



EDIT took some fuel out of the fuel filter put a match to it and it set alight.... so guessing i put petrol in it.... how can i see how much damage it done....

Drain what's left in the tank, fill her up with diesel and hope for the best

Didn't you get a receipt? It says what fuel you bought.

This. Had a 3 series in the other day with petrol in it, new fuel filter and a drain, can of diesel in and it seems fine.

Also this?

Isn't £20 worth of petrol 17 litres?
That might be in the territory of brim the tank with diesel and keep doing that asap.

Change the filter first though, and change it after the a tank has gone through it.

Drain the tank first, modern diesels can't cope with it the same way the older stuff does, destroys the fuel systems.

I'm not so sure... Probably said this before but I'll never forget it lol. On work experience we had a 3 year old (2008) transit TDCi in with poor starting. Ran fine just took ages to start, had been playing up for about a month according to the owner. Did a few tests and then checked the fuel - strong smell of petrol. The owner was adamant he hadn't put petrol in, but admitted to filling up about a month earlier the same time it started. He had tonnes of fuel receipts in the glovebox so I checked them all eventually finding one for about half a tank of petrol lol. So it'd done a few hundred miles including an Ipswich to London trip with no ill effects apart from the poor starts!

We drained off what was left, changed the filter and nipped to the petrol station for a jerry can of diesel. Worked fine after lol. It's a very distinctive van and I've seen it about several times since so can't have done any major damage!


I also had to drain off 2 when I was at Honda in 2007, but both of those had realised immediately and not driven them, couldn't believe how common it was though. Then one of my mates at the time topped up his PD Golf with petrol from near empty and it cut out 5 miles down the road. Just drained it off, changed the filter and was fine after.

I'm really not sure modern diesels are quite so allergic to petrol as people make out... I've seen veg cause more damage than petrol tbh lol.

The vectra dti (dreaded vp44 pump) has been filled up 4 times in a year with petrol (20 quid) simply topped up with diesel and been fine.. Didnt even change the filter once! Lol
