According to this Telegraph article if you unlocked the car door after misfilling with petrol it creates a rush of petrol into the injection system. No need to start the engine to cause damage.
Ive never heard of this one before, is it factual?.

I read the piece in the paper on Saturday, slightly over dramatised though the message is clear.

Although it's a petrol, my daughters Seat Ibiza does that - but I think it's only when you actually open the door, not by unlocking it. It's quite an alarmingly loud, 'urgent' noise too.
As it's a VAG group car, which share a lot of engineering, then I imagine many VAG models do the same thing.
In a similar vein, don't some VAG cars energise their glow-plugs when the door's opened?

What I was really asking was whether there is any truth or facts to substantiate this story. If it were true even if the driver realised his error afterwards the car would be virtually unmoveable.
unlocking diesel car door ruins engine - Aprilia
Basically it is true, yes. The costs to replace the fuel system are a bit inflated though. Opening a car door can result in quite a few things happening these days (like having your fingers chopped off if you're working on late E-class front brakes at the time!).

Energising a lift pump for a few seconds will not "DESTROY an engine" and will NOT in "most cases result in a £7,000 bill".
The article is rediculous and uses chains of extreme events to illustrate outcomes which probably have lottery jackpot likelyhood in real life.

I agree he is exaggerating rather, but the article is a timely warning. The engine won't be destroyed. However circulating petrol into an HP Diesel system means the the engine should not be run at all. The car should be trailered away and the entire fuel system cleaned out.
If the engine is started then there is likelihood of severe damage to the fuelling system. This IS likely to entail a bill of £1000's for a repair. Mercedes, for example, advise dealers that if one of their HP Diesels is run for even a couple of miles with petrol in the fuel, then the fuel system components should be replaced.

I have filled up with diesel just once, with our Xantia about 8 years ago, The car ran perfectly normally for about 2 miles and then came to a sudden stop.

But....

if you can't open the door, what **should** you do that wouldn't also involve opening the door?
unlocking diesel car door ruins engine - trancer
I am thinking, brick through the window, climb through, unlatch the bonnet and disconnect the battery. You can then climb out and explain the whole situation to the nice policeman who has now arrived on scene to investigate an attempted theft of a car. Sorry...cars don't get stolen in the UK...I meant TWOC.

Technology gone bonkers.

I'd rather go back to my Capri than put up with some of this over-complicated junk. Modern designers have far too much time on their hands, they should be sent to clean the toilets when there is no real work for them to do.

Just get someone out to drain the tank, I would imagine. If the engine hasn't been run, I can't see how it is going to be damaged. It never did any harm to the our Xantia's engine after having driven for over two miles without realising that there was petrol and not diesel in the tank.

I don't think a Xantia from 8 years ago had the diesel technology to which this scare story relates!

I wouldn't imagine it did for one moment but how is any diesel engine going to be ruined simply by injecting a little petrol into it?
unlocking diesel car door ruins engine - machika
My point is that the XUD engine may be an example of old technology but I was actually driving the car before I realised what had happened, so a good deal of petrol would have been injected into the engine. It didn't do any harm to the injectors or engine, even though it was left standing with petrol in it for some time.
unlocking diesel car door ruins engine - Aprilia
Its not the engine that gets damaged, its the injection system (pump and injectors). In a common rail system when the pump runs it continuously pushes fuel through the system at very high pressure (20-30,000 PSI). If petrol gets into the fuel then pump lubrication swiftly starts to break down, hardened metal surface starts to break up, swarf gets into the system etc etc. Once the system is contaminated with petrol it is quite difficult to get it 'clean' again. That's way many manufacturers (eg Mercedes) will not warrant a misfuelling repair unless the systems components are replaced with new items. Cost is £XXXX (insert your own numbers for X).

8-year-old XUD is simply not relevant.

At various times on this forum, BRers have suggested adding a small quantity of petrol to a diesel tank during winter driving, to prevent waxing.

In view of all the above, should we now not add petrol to our diesel tanks durimng below freezing temperatures?

OK: So what do we think to running cars like this on rape seed oil? I understand that the method is to add what? 10%? of white spirit? I guess that white spirit is slightly more "oily" than petrol, and maybe RSO is "oilier" than diesel?
It seems like sacrelige to put cooking fat in a Merc, but with the price of diesel these days, you could pay for a new injection system within a couple of years.
If it ran for that long.........?

You shouldn't run Common Rail or other very high pressure diesels on vegetable oil, however some have with modifications, but longevity results are not available.

If I had a car still in warranty, and some cock-up of my own making made it break down, the last people I'd call would be the dealer. I'd have it sucked dry and refuel, and if there was still a problem, then go to the dealer.

I'll be happy to run my 302d on vegetable oil, any time that the oil supplier and BMW both say it's fine to use. (And if it's cheaper).

Slight change of topic, but on similar lines: I once put a pint of windscreen wash fluid in the engine oil filler when I was distracted while doing a general underbonnet check. Didn't have any short term effect - I can't tell you about any long term one though.

As HJ and others say, flush it out and hope the pump wasn't damaged. I'd add that I bet many would then sell the car immediately. Which thens raises the question, what's the best way to buy a second hand common-rail or PD diesel? If you go to a dealer, you don't know the history, but will have some warranty, or buy privately, so you can quiz the seller, but have no come-back if it the fuel system distructs prematurely some time later?

If someone misfuels an expensive Mercedes or BMW diesel, and the fuel gets through, as Aprilia writes, they face a huge bill

(usually £3k - £4.5k)
If the system still gives out (which it might) then they
have to fork out the money. But if it doesn't they
have saved big money. HJ

But If you really do a BIG job of mis-fueling.

The report on Abramovich's yacht reminds me of the time my Father was collecting a new yacht from a Dutch yard. In the rush of final preparations someone managed to put water in the diesel tank. Draining out the tank and removing the last of the water from the fuel system took a considerable time. Thank god it was not the other way round with diesel in the water tank as the complete water system would have had to be stipped out and replaced.

Might not be so as some diesel would be left in the fuel pipe and be used up first.
