Help - I've done something really stupid....

"Bald eagle" gurgled happily, sounding much like they were saying:

Google for "misfuel common rail diesel".

Then ring the AA to come and drain the tank.

Quite possibly not, drain the tank, drain the fuel filter, flush the pipes with diesel, & fill it up again.

Having googled a bit decision has been made. RAC coming to drain and flush tank. Had hoped that dilution would have been sufficient but doesn't look like it.

Once they've done that, punt it on quickly, as it may well still have caused you some problems.

And this, children, is why you don't want to buy a used common-rail diesel.

Ever.

Did you just call me common. Shakes tic tacs at you!

Your likely to damage the fuel system

Bit late ennit? Unless he's posting from the petrol station.

Twas what I was thinking...

Some common rail cars with keyless entry run the pump as the car unlocks, in order to minimise startup time. Mis-fuelling one of those is a really bad idea!

Is that really enough to damage a new type diesel system? Bloody Hell!

The jury is out on that. It would be if the tank was full of petrol, but with 2/3 diesel as the OP suggests, there should be enough lubricity to avoid damage. Of course, no-one in the trade is going to cut their own throat by telling you that less than an entire new system is necessary.

Yes , desiel pumps rely on the lubricating qualities of the fuel , petrols a solvent .

Even just switching on the ignition without starting the engine can wreck the low pressure pump as it pumps fuel around .

Its not unkown to have to replace the low pressure pump , filters , common rail unit

Start the engine and its likely the high pressure pump , injectors and on some vehicles even the fuel tank .

Not unkown for bills running at £3000.00

But not running the whole tank through's still sensible.

Even running for a brief period can cause the case hardened rollers in the pump to lose their hardening. This won't necessarily cause instant failure, but will shorten the system's life dramatically.

Chris

On some keyless entry vehicles, you don't even have to do that to wreck the pump...

Chris

Yeah but, is this * actually* true? My brother in law filled his Berlingo with petrol and drove it until it died. After a drain and refill with diesel, it ran for thousands more miles. It did need a new injection pump this year though but considering that he drove it to a grinding halt, I'm surprised it ran at all.

Where "new type" is heading rapidly for a decade and a half old...

Even "Old" types don't like detergent oils.

You answered your own question , the fuel pump needed replacing .
