Kept Driving With Petrol in a Diesel Peugeot 407?
The motor wants switching off and keeping off as soon as you can pull over somewhere safe, if you've travelled with petrol in a diesel Peugeot 407. We can still sort it out wherever you have stopped, and if it's caught early, lasting harm is very rare.
Your Peugeot 407 can remain wherever it has ended up, as Petrol in Diesel comes out to it, drains its fuel tank on the spot and clears its fuel system of petrol. By the time we go, your vehicle is back on fresh diesel.
Warning signs of petrol in a diesel 407
To begin with, petrol inside the tank frequently makes little difference to how a diesel 407 drives, and the symptoms show up a couple of miles further on. Drivers normally spot the following if there's petrol or AdBlue in the fuel tank:
- the engine lacks power, especially when you ask it to accelerate
- it idles unevenly, or it runs rough
- the tailpipe puts out more smoke than usual
- warning lights show
- it stalls and may not restart
Look at the receipt if one of these began after you filled up, as it shows which fuel was put in.
Wrong fuel in your Peugeot 407 and the result of driving on it
Driving is what takes wrong fuel in your Peugeot 407 from your tank and on through the filter, your high-pressure pump and your fuel injectors. Until the engine pulls it out, it stays there. The mixture reaches more of the system the longer the 407 is driven, because petrol weakens the diesel fuel that protects your fuel pump and the fuel injectors as it passes through them.
Stopping as soon as you can is better than finishing the trip for that reason. A vehicle that is stopped early usually needs nothing more than a drain and a clean. What can do harm is covering a long way on contaminated fuel.
Yours being the 407 HDi FAP 205 Bi-Turbo rather than any other version of the 407 makes no difference.
Where you have pulled up
The 407 does not need moving anywhere. No tow has to be organised and there's no reason to start it, because we come to it at the side of the road or outside your house.
On a main road, turn on the hazard lights, then choose somewhere safe to wait away from the traffic.
Call 0333 366 0103 and tell us where you are, what 407 it is and roughly how far it has been driven. Knowing the version from the badge, like the 407 SW HDi 205 Bi-Turbo, helps too.
Fuel drain on your Peugeot 407 after it was driven
There is a step more to a fuel drain on your Peugeot 407 after it was driven than to one at the forecourt. Draining your tank comes first. After that we open your fuel lines and rinse them through with the filter, until there is no petrol left between your tank and the motor. Before our technicians go, the motor is started to check it is running smoothly on clean diesel, once your system has been primed.
AdBlue in a diesel Peugeot 407 after it has run
Rough running, smoke and warning lights are the usual symptoms after you've driven on AdBlue in a diesel Peugeot 407, and your car might then stall. The fuel pump picks up fuel from the bottom of your fuel tank, which is where AdBlue sinks, and so it reaches the fuel line quickly. It also doesn't burn or lubricate. The urea crystallises in your filter and your fuel lines as its water dries.
AdBlue removal from a diesel Peugeot 407
AdBlue removal from a diesel Peugeot 407 that has been run means emptying your fuel tank and then flushing the crystals from the lines and your filter, and we replace your fuel filter if it needs it.
Just your diesel tank is worked on here. If your 407 has an AdBlue tank of its own, it's left alone, and nothing here involves taking out or disabling the AdBlue system.

Fuel drain on the Peugeot 407 after driving: what it costs
The price of a fuel drain on the Peugeot 407 after it's been driven hinges mostly on how far it went and where it has ended up, and whether it was petrol or AdBlue makes a difference as well. Call with those details and we can tell you what the job will need.
Common queries about petrol in a diesel Peugeot 407 after driving
Is the 407 done for now?
It's very unlikely. Permanent damage is uncommon when the vehicle is stopped early and your fuel system is emptied and cleaned, and that's what we do wherever you've stopped.
Is it OK to drive it home first?
We would ask you not to. Each mile on contaminated fuel pushes it further through your fuel system, and we're able to empty the 407 where it is, which means there's no reason to shift the car.
It won't restart after stalling. What now?
Please don't try once more. Leave it as it is, since every attempt draws more of the mixture through. We start it for you after draining and flushing it, putting fresh diesel in and priming your fuel system.
Do you need to know which 407 I have?
It's useful when you call if we know which of the 15 diesel versions of the 407 you have, and the boot badge shows it.
Wrong fuel in my Peugeot 407: does insurance cover it?
We come out whatever your policy says, and some do offer misfuelling cover, which means checking yours once the car is sorted out is worthwhile.
