    Ask yourself "where did the additional oil come from", leaking injectors raise the level and dilute the oil.

    You beat me to it, a raised (thinned) oil level is the confirmation symptom of injector wear diagnosis in addition to white smoke

    Quick update on this. Brought the car for service. They found double the correct amount of oil in the car. They drained it and put in the right amount as well as adding a turbo cleaner to the fuel tank. Car ran great for 2 weeks since. Today started with the white smoke again after the engine had been turning over for a while. Tested the oil and again too much, so it's clearly diesel getting into the oil. Guy at the garage reckons it's a leaking pump (I guess fuel injector pump?). Does that sound reasonable? Any idea what that's going to cost to replace?

    Denial is not a river in Egypt… If you mechanic thinks it is the remotely mounted belt driven totally sealed from the crankcase high pressure fuel pump I suggest you take it to someone who knows what they are talking about and get them to change the injectors! The injectors are £538.42 each from Audi and there are recon exchange units from Bosch which I have seen from around £220 but bear in mind you have to return the old ones. If you need conformation, get someone who knows what they are doing to carry out the diagnostic procedure as outlined in the VAG Technical Product Information notice I posted earlier.

    "get someone who knows what they are doing" - apparently this is easier said than done. I asked the guy who runs the local kwik-fit type place (who did the service) what he thought and he immediately said injector fuel pump. He sent me to another garage to get their opinion (a well known local place which has been around for years) and the guy also immediately said the same thing (they hadn't consulted). Yet you're telling me it's the injectors and can't be anything else - how could a senior mechanic at a well known garage be so wrong? My only alternative to this place is the local audi place which in my experience tend to pick the most expensive possible option and hope that works. And if it can be anything other than a €3k solution that isn't totally absurd I'm happy to try it.

    I guess this is PD engine and there is no HP fuel pump.
    Each injector works as fuel pump driven by camshafts.
    Its clearly injector fault you can call them Unit injectors, pump injectors, whatever you want

    You say this is a 2005 3 litre and you have posted in the 4F section so it would most likely be an BMK or BNG code engine as the ASB came along a year later. These are Common Rail injection engines that use an in tank lift pump to deliver the fuel to a belt driven high pressure fuel pump externally mounted in the middle of the engine V and it is simply not possible for this to leak fuel into the crankcase.

    The only way the fuel pump is leaking fuel into the engine is if someone has drilled a hole in the pump and the engine block so the fuel runs into the the engine. It's your money but I would never waste hundreds of pounds when the known issue are leaking injectors. But if you have deep pockets and don't mind wasting money replace all the pumps, pipes, sensors etc then once all the has been discounted go for the known issue.

    The thing to bear in mind here is that you are conversing with an expert when Crasher is part of the conversation. He is not just an interested amateur - he runs a VW/Audi specialist independent workshop and spends every waking hour working on these cars (apart from when he's drinking wine, but that's another story ) I have spent many years as a member of this forum, and I can attest to the fact that he knows his stuff. It's your car, your money and your decision on how to proceed, but don't discount his advice lightly.

    Good luck - whatever you decide!

    Cheers!
