Oh dear, I finally made the fatal mistake of putting petrol in my ML270CDi - anyone got any ideas as to what I can expect to have to pay to repair the car - I drove it for a short while until it just cut out.
I have seen this many times and this engine is usually okay. The best advice that I can give is to empty the tank ( not the easiest tank to empty ) Put new Diesel in then change the fuel filter and prime/fill the fuel lines. If it then starts I very much doubt there will be any long term problems. If it fails to start then it would be a first for me but you would have to find the cause of low fuel pressure.
To qualify my advice I used to repair Ambulances with this engine in, and believe it or not they used to wrong fuel at least one a week.
there are specialists who will come to your house and empty the tank etc- usually they leave cards at petrol stations for just such instances (I guess it happens a LOT)
Merc say it's repairable... so just have to bite the bullet and remember never to do it again. Shall be ringing Tesco to find out what colour their Momentum 99 fillers are too. As I'm pretty sure it was black....
