    Case Study: 2011 A8 with P1926 and P1927 codes

    ST?ID=78452

    Joe calls up today, working on a 2011 A8 with a 4.2L CDRA engine, MIL on. 2 fault codes in the ECM:

    4661 - Relay for Aux Coolant Pump (J496)
    P1927 00 [104] - Open Circuit

    4663 - Relay for Aux Coolant Pump (J496)
    P1926 00 [104] - Short to Ground


    Normally any "Open Circuit" or "Short to Ground" type fault codes are simple, check the electrical paths for the item in question... fuses, terminals, wiring, the part itself. However, what caused some confusion here... the CDRA engine does not have a J496.

    So here the meat of this Case Study... slow smoked tender tasty meat..... you will may come across fault codes that have a Component Location that isn't relevant to the actual car you are working on. The more common example one might run into on V6, V8 and V10 FSI and TFSI engines are these codes:

    18726/P2294/008852 - Fuel Pressure Regulator Valve (N276): Open Circuit
    18728/P2296/008854 - Fuel Pressure Regulator Valve (N276): Short to Plus

    The V6, V8 and V10 FSI and TFSI engines most likely won't have a N276, but rather the factory repair manuals and wiring diagrams will refer to it as the N290.

    So what does one do when they run into something like this? Use the grey noodle is the starting point. With Joe's vehicle, J496 isn't referenced, but we are given a clue in the "Aux Coolant Pump", so something to do with an electrical coolant pump. Looking at the wiring diagram for the CDRA engine, I do find listed a V51 After-run coolant pump, so this is a strong candidate for the source of the fault codes.

    I can also look at other engine wiring diagrams and find one that does actually have the J496 relay and from there, I see these will power a V51 Aux Coolant Pump, so we can start connecting more dots now. Dr Peter was also able to find a test plan linking the P1926 DTC directly to the V51 on the CDRA engine, thus confirm what we suspected.

    Now this next part is my "educated" guess, but on the CDRA engine, the V51 coolant pump has 3 wires on it and I suspect that inside this unit is a relay. I'm not aware of any control module that directly operates an electrical motor, it is always a relay (mechanical or solid state) of some sort. If the J496 is built into the V51 unit, then the factory repair manual doesn't need to mentioning the J496. But from a diagnostic stand point, the ECM is saying "that relay I pull ground for has some sort of electrical path issue" and thus the P1926 and P1927 codes get flagged. I guess years ago when DTCs were being written, the J496 relay would always be a stand alone part. And when it was integrated, the wasn't a way to rewrite DTCs, so this was the best option the engineers had to explain what the problem was.

    Anyway, now the next person who runs into this issue has a Google chance of figuring it out quickly.

    Regards.

    A "Aux coolant pump" is normally fitted on cars with the aux heater, but sometimes not, depending on MY. I have coded some aux heaters on the 3,0 and 4,2 TDI ROW engines (Audi A6, A8, Q7) and there is a coding option in #8 or #18 for this valve to be activated or not. With this valve open the warm cooling fluid produced by the heater can circulate in the engine.

    Don´t know if this helps, but maybe a coding is messed up somewhere.

    Got a 2011 A8L 4.2 a couple weeks ago and ran into this same code. Got a new V51 pump off Amazon and since I'm an idiot, I tested it by hooking it straight to 12V battery to make sure it works before installing. It did work like a second and then not a peep. So to see what's going on and to my horror, I actually found a PCB inside the old pump. Anyhoo, just in case anyone's interested, here's a picture of what the insides of this pump looks like.
    And a link in case the embedded pic doesn't show: https://imgur.com/a/pc19v9j

    I would like to add to this that most MQB EU cars with upgraded climatronic get a residual heating function automatically. Which is in no means an auxilary heater, but every single car that has a residual heating function will have an auxilary coolant pump.
