Hi everyone, I was the unfortunate winner of getting my diesel Qubo, filled with petrol.
The tank was relatively empty, then filled with about 5 litres of petrol. Drove home, everything was fine, started the next morning and felt it didn't idle right, something has to be wrong. So I backed it out the driveway to get my other car out. When I got home that afternoon, I saw on the slip that my suspicion was correct - petrol in the diesel.

So long story short. What is the easiest, cheapest way to:
1. Draining the tank.
2. Flush the filter.
3. Check for other potential issues.

I am not in the position to afford taking the car to a mechanic, luckily I am capable and a quick learner.

Basically as you say, empty tank completely with a suction pump ideally through the fuel sender unit/low pressure pump in tank then refill tank with correct fuel, remove fuel filter outlet pipe and turn ignition on to pump /flush clean good fuel through system, ideally then I would replace with new fuel filter, once clean fuel is coming out of fuel filter and going to the high pressure injection pump, most modern diesels will self bleed from there on.
Then I would start the engine , but just let it idle with no load until diesel has got all through the system again, before gently trying it on the road till you feel it is back to normal.
All this is if you are lucky and fingers crossed no damage done to the high pressure pump and injectors, the reason being petrol is a spirit where as diesel is an oil, the diesel is a lubricant for all those extremely high pressure injection parts with very close tolerances. Petrol injection systems are designed to run without that lubricant side.:)
