Volkswagen Passat Oil in Fuel

    Hi Guys,

    Im wondering if anybody can help me. I have a 2006 2ltr Diesel Volkswagen Passat. Just got a service yesterday and was told there was oil in the fuel filter.:eek:

    The Mechanic said he thinks it could be the seal on the tandem pump. He said i would need the pump to be replaced. He quoted €300 for the part and €350 for the labour which includes cleaning out the fuel tank and €40 worth of Diesel - does this sound right?

    Any other ideas of what could be causing it?

    The car was subject to two recalls, the injectors were replaced by volkwagen in feb 2012 and the fuel pump was replaced in 2007.

    Any help/advice wold be greatly appreciated!:)

    Id be thinking about selling it and moving to a lower tax 08 2.0tdi from the North. Most of the May onwards UK 08's are without DPFs that cause trouble yet have the newer common rail unit which is quiter and more reliable. The cost to change isnt alot more and you will have much higher residuals if you sell in a year .

    Otherwise Im sure of the regular mechanic posters will chip in with a current solution.

    They all leak a certain amount of oil into the fuel via the tandem pump on the end of the cylinder head. So the fuel filters are always black when being changed. As long as there are no running issues I wouldn't worry about it at all.

    Thats it! the tandem pump, that's what he called it, i couldn't remember the name!
    He said it wasnt urgent but would definitely need to be looked at as its only going to get worse...

    With regard to running issues it has been a bit smokey and the oil needs to be topped up more often, but thats all really....

    I wonder does anyone know if you can just replace the seal or does the whole pump need to be replaced?

    Also does €650 seem like a reasonable price to have the tandem pump replaced?

    You can change the seal on its own. It is unlikely that there is anything wrong with the tandem pump itself so there isn't any point in changing it.

    €650 is way too much anyway even if the tandem pump did need changing. There is no need for cleaning out the fuel tank or anything like that.

    The only reason for changing the seal would be in the case of really bad fuel contamination, as I posted above a certain amount of oil (enough to turn the filter black without turning the fuel itself black) is completely normal.

    I would say even if you do spend €650 getting the pump and seal changed plus everything cleaned out that by the time the fuel filter is due to be changed it will be black with engine oil again to be honest.
