Engine fault S6 2015

    Hello,

    My 2015 S6 developed an engine fault yesterday and limited the revs to 4000. I have a basic code reader which gave P0021 and P0018 which I believe are related to the crankshaft sensor. The car has done 51k and is standard.

    The car drives totally fine except for the warning lights and lower rev limit.

    My usual mechanic had a look at it today and took it to an Audi diagnostic specialist who said it's actually a correlation error between the camshaft sensor and the crankshaft sensor. I think he said Bank 2 sensor A but I could be wrong, but it's definitely just one bank.

    My mechanic recommended I try an Audi specialist for a repair so my first question is can anyone recommend anyone in the northwest? Particularly in the Manchester or south Lancashire area?

    I have phoned Volkmaster in Bury as they are probably the closest. Without seeing the car they were talking about potentially replacing all 4 cam chains and a bill of between £2.5k and £4k and engine out.

    I've got a list of other garages to phone tomorrow but I'd like to get some recommendations if I can.

    I did find this post where someone in the US had the same issue but seemed to get a cheaper fix?

    Any help gratefully appreciated.

    Thanks

    That’s doesn’t sound too good tbh mate, it does sound like if there’s a differential angle between the 2 it’s chain related, or sensors are buggered.
    Fingers crossed bud!

    Cheers. I'm booked in with awesome for a diagnostic on Monday and they seemed to know their stuff.

    So fingers crossed this doesn't cost me a fortune!

    Cheers,

    Well it's not good news, it looks like it's the tensioner or the chains so I'm booked in to have the engine and gearbox out next Monday. And as you can imagine it's not going to be cheap!

    The swapped the cam adjusters over from one bank to the other and the fault didn't move with them, so that's ruled them out.

    Does anyone know, are the cam adjusters and actuators the same thing?

    Cheers

    Well that sucks! Defo a big bill. Have they quoted you for the cost of the work and given you a breakdown of what will be replaced etc?
    Have you had your oil screen done as yet?

    No oil screen yet.

    They've quoted to replace the cam tensioner and the list of parts being replaced is a page and half long. They've gone for the tensioner as they think that's most likely but they can't really say until the engine is out.

    Just short of £3500. Ouch

    Sorry to hear that mate, it sucks.

    Regarding the oil screen, is this to upgrade it to the rev G or something else?

    Cheers.

    I'm coming to terms with it, I was gutted at first but I've never had a major issue with my previous cars so I guess I was due one.

    Not much I can do about it other than get it fixed.

    Oil screen failure is a common fault on the S6 engines and some rare RS models. Its not if its when it will fail and then its big bill for turbos and possibly engine rebuild depending on how bad they detonated.

    G is the latest revision for the oil screen. there is also an oil screen relocation kit available

    Just thought I'd post an update. It was a tensioner which had failed and damaged one of the guides, which i think are only made of plastic.

    All fixed now and seems to drive perfectly. Just done a 1000 miles in a week on holiday in Scotland.

    Not sure if I'm going to keep the car though, much as i love it i couldn't cope with another bill like that so it may have to go for something newer.

    £3500 for the timing chain work including oil service and air con re-gas, plus a fuel pump needed replacing so came to just under 4k. The car was due an oil service soon anyway.

    Thankfully the garage I used offer 0% finance which helped a little.

    I know. Apparently I've been unlucky but you also read stories about gearbox and turbo failures but I don't think my wife will forgive me if I keep it and something else big goes.
