    So I had the engine warning light come on a couple times last week and so I bought an ODB2 scanner (Carista). It's giving me the above error code.

    Before I book it in at the garage, does anybody have any suggestions of things I could check that might be doable at home?

    The Carista app is quite good, I've enable the needle sweep and offside mirror dip on reverse functions.

    I've taken it to my local garage and he's said that he can't see anything obvious and to leave it until it gets worse. Well now the engine light as well the flashing glow plug light is on. It's come up with a code (05171) that I can't find anywhere is that even an error code or just an engine id? I'm not sure what to do next.

    OBD2 - confirmed:

    P0299 - Turbocharger/Supercharger "A" Underboost Condition



    OBD2 - pending:

    P0299 - Turbocharger/Supercharger "A" Underboost Condition



    Engine:

    05171



    Ignition authorization:

    02823 - Requirements for Locking the Steering Column Lock not met

    Local Garage couldn't find the issue so I've taken it to an Audi dealer, hoping they can find the fault at least...

    60 or 80 quid (I don't remember which) for them to tell me it's Underboost on the Turbo, "yes I told you that was the code already"
    plus another 140-280 to investigate further.. I hope to f*** it's just some faulty electronics when they call me tomorrow.

    Any ideas on how I can navigate this with price negotiation?

    With audi they are a law of their own. If the car is under 4 years old with full service history then they may help with costs.

    Update on this.. I've got the car back.. They spent 5 hours investigating but have charged me for 2 and waived the initial inspection fee and cdw on the loan car they gave me. They suggested further investigation around the turbo and actuator which they said felt a bit loose. Not sure what to do next, looking at VAGManchester as their hourly rate is cheaper but they'll want to start again from scratch.

    It’s bad news, they’ve identified what the problem might be but needs further investigation and they can’t do it. I didn’t quite understand what I was told on the phone but some some equipment which is needed is only available to Audi so it needs to go back to the dealers. The problem area is to do with the thing that switches between the two turbos. Sigh.

    Any idea how much it cost them to fix? I've just got off the phone with the dealer and they want to book it in for 5 hours to investigate, reduced hourly rate to 104 quid though.... I don't really have much option from what I can see.

    The dealer just called me... They say it needs both turbos replacing because it's a single unit cost - £5800

    Warranty? If not try the "WTF I've only done xxxii number of miles & the cars only xxx years old....shed a tear...etc..." to the head of whatever dealership you bought the car from &/or are trying to get the repair done by. They might chip in for good will if it's FASH and only just out of the 100k/5yr bracket. Maybe. Certainly worth a try. Lay it on thick. What have you got to loose?

    Otherwise - pucker up & bend over - no lube in the world is going to ease the pain, but at least you'll have two new turbos to play with!

    I'd heard the repair costs on the turbos was brutal, shame your having to experience it first hand. Good luck.

    ring around turbo specialists and see if any of them refurb them. i imagine plenty do, the problem and maybe the expensive part would be getting them took off the car by the same people, some are a walk in service only. for sure, this wouldn't be the route audi takes, they just replace

    Bit of an update. The dealer has offered to reduce the cost by 40% so 3400, which I appreciate but I still think it's ridculous that the turbo has gone due to wear and tear at this mileage with a FASH. I've also asked that guy on piston heads who had a similar situation what his amount was reduced to, so hopefully he can give me a bit more ammunition. My brother in law (Senior JLR engineer) says he thinks I should fight harder as it shouldn't need replacing due to wear and tear at that age. I've opened a case with Audi UK, and I'll see where it gets me. I've got a fairly nice Q3 as a courtesy car still so I'm happy to ride this out for a while.

    Push the dealer to get as close to 2k as you can then bite their hands off. Remember, FASH & the warranty on the parts & labour for such a potentially expensive part will certainly recoup any monies when it comes to resale. Should you choose to keep the car you don't have to worry about turbo failure like the rest of us :)

    Buy cheap. But twice.

    Just an update on this.. Car is back with me and has a new turbo installed. Total cost ~£3500, waiting to see if I can get my next service free and a discount on a new warranty from Audi Customer Service rep. I'm considering writing a letter to Audi about the whole thing but to be fair to the dealer I think they've done what they can. On my next car I will definitely make sure it has a long warranty, kia stinger?

    Unbelievable. Just taken the car for a dr Be on the motorway and limp mode comes on. Carista says it’s the same error code. Fuming
