    2013 Audi Q5 Hybrid - P2681 P2682

    Check engine light came on. Scanned 2 codes.

    P2681 Control Circuit for Coolant Bypass Valve(Open Circuit)
    P2682 Control Circuit for Coolant Bypass Valve (Short to GND)

    Vehicle otherwise runs fine.
    Cabin heating operates fine.
    No noticeable coolant loss.

    I read that it could be related to solenoid valve N82. I found 2 identical solenoid valves at the back of the engine, mounted back to back. One on top of a plate, the other below the plate.
    I replaced the top one. Some documentation suggests it is N82, other documentation suggests it another valve identified simply as '3' on a cooling system diagram.
    Appreciate any suggestions on how to troubleshoot this further.

    I just had the same (P2681) code on my Q5 Hybrid. Did your solenoid change fix the problem?

    I've been searching thru my copy of the shop manual, and it is the lower solenoid valve N82 that is the culprit for P2681. Damn thing is virtually impossible to see from the top - one can see the hoses going in and out, and I think I put a finger on the connector toward the back but I can't actually see the connector or the wires. Draining the engine coolant is the first step in the replacement process according to the manual. The R&R instructions seem to be very simple, a page or so and a few lines, but access there is really difficult. I'm going to try finding the actual part on-line to see how its shaped and whether or not I did touch its connector.

    I changed the top valve (N422) originally thinking that was actually N82. It made no difference.
    Changing that top one is real awkward. Very hard to access the back of the engine. But I was able to do it.

    Then I realized that N82 is underneath that one. I tried to get to that, but access is almost impossible. It seems simple enough per the manual, but actually accessing it in the real world is a nightmare.
    I couldn't even get the N82 connector off to troubleshoot any further.

    So it is in at the dealer right now.....

    Okay back from the dealer.

    The N82 coolant solenoid valve was leaking into the electrical connector and through the wiring harness towards the ECU.

    New valve, new connector, 6 inches of wiring harness replaced.

    Moral of the story: It is disappointing how much damage these dumb valves can potentially do. Pro-actively checking the connectors on these valves for leakage is probably a wise move.
    Unfortunately, some of them are very difficult to access.
    If you get a MIL code and suspect one of these solenoid valves I'd suggest getting on it right away to limit the damage.
