    oil seperator tsb be aware

    There is a lengthy diy around replacing your oil separator on the forum. If you have had the experience of this malfunction it is unreal the engine sucking air in through the oil cap and sound is disturbing. Especially when you have the apr tune and don't want the engine to be damaged and reflashed before getting to the dealer. After taking it to a local shop they knew exactly what was going on and it was a known issue. Nobody could tell me if the car would be damaged by continuing to drive. Couldn't get into my apr dealer for a week for the flash and audi gave me almost a week and a half out. Needless to say I rented a car and left the 7 in the garage.

    I just have had my vehicle returned from the dealer with this being replaced under my cpo warranty, yet Audi of America originally wasn't going to pay for it. It was covered and I noticed looking at the paperwork that there is a tsb 2040644/10 for replacement of the oil separator so try that with the dealer and see what they say. It is bullshit that this isn't covered with this tsb out there.

    Unfortunately the TSB 2040644/1 May 13, 2015, lists 2013-2016 models, so even some of the newer cars may have this issue.

    Model(s) S6, S7, RS 7, A8, S8
    Year: 2013 - 2016
    VIN Range All
    Vehicle-Specific Equipment 4.0T

    "Condition
    A metallic whistling or grinding sound is heard from the engine compartment when the vehicle is at idle speed.
    The sound usually only occurs when the engine is warm.
    The MIL is sporadically on.
    The following DTCs are stored in the engine control module (ECM), J623 (address word 01):
    DTC P2279 (Intake air system leak)
    DTC P0507 (Idle control system RPM higher than expected)
    Technical Background
    A leak in the crankcase breather module (pressure regulating valve) can cause this condition."

    Anyone know what this would cost via an independent shop? May just do it as preventative maintenance.

    You can order the part for $254 (with free shipping) from audiusaparts.com. You will want part number 079-103-542-E .

    You can then take it to an independent shop (depends on their hourly rate), but I'd expect roughly 8 hrs of labor.

    Or you can follow WhiteWhiteS7's DIY thread here on AZ and do it yourself for free!

    audi told me it is a 3K to do this service. I heard through another source they have been reimbursing people who have paid it themselves. They did replace a few hoses as well for a charge.

    Would recommend finding an independent reputable shop and source the part(s) yourself. It will cost you less than half what your dealership will charge. To be fair, it is labor intensive, but if I can do it in less than a day, a professional mechanic working at a deliberate pace should cost you no more than about $1000-$1200 in labor.

    Although I did my own oil separator swap as well as my own turbo upgrade, the DIY for the oil separator swap here on AZ was written by WhiteWhiteS7. I'm not sure I would have had the courage to do it had he not taken the time to do that write-up. I was simply commenting that if a total amateur like me can do it in a day following WhiteWhiteS7's thread, pretty much anybody can do it.
