    '09 Touareg 3.0 TDI sudden limp mode, man code. Help please.

    Hi everyone, I'm currently verified but for some reason unable to post in the Car Repair forum. I was hoping to get some help ASAP before I pull my hair out and end up taking this beast into the Stealership.


    Some context, I was driving to work last week....my Touareg started fine, drove fine, etc until about 5 mins into my drive it just lost all power and got a flashing check engine and a flashing glow plug light and it said "Workshop Fault"

    I limped it home and scanned it, but I only scanned the 01 Engine module and came up with these codes...

    Code:

    I was reasonably certain it was the pressure sensor on the AdBlue pump that died so I replaced that but it did not solve the problem. After clearing all the codes in the engine module and they came back, I decided to do an AutoScan and this is the result.

    So I think there is something SERIOUSLY wrong here and has to do with the electrical system. Electrical gremlins are not my area of expertise so I was hoping someone on here with more knowledge and experience could help me out. I'm really hoping to get to the bottom of this myself so I don't have to take it to the dealership and have them bend me over the counter...

    I've never seen this many "Malfunction" codes on modules before. Could this be an indication of a wiring issue or perhaps the ECU dying? or a problem with the CAN system?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    I've just sent in my verification form on the VCDS site, so hopefully I'll be verified soon. Really hoping someone can help me out with this issue...

    So iet's have a look what the G686 Pressure sender for reducing agent metering system and the reference voltage have in common. Absolutely nothing

    First DTC
    G686 itself could be broken. I have no idea where to find it, probably on the AdBlue system, somewhere.
    The wiring could be broken (check the wires from ECU to the sensor, T94/11 T94/17 and T60/38 to the sensor). Verify all wires end to end with a multimeter.

    Second DTC
    Reference voltage B is something thats calculated inside the ECU itself. From what I can read, it's not dependent on any wiring.
    A fault inside the ECU would be the first suspect, but fuses are easier to check:
    S9
    S15

    Also verify the earth points and wiring (on bulkhead, Earth Point 1). Maybe they are corroded or dirty.

    Same issues, less DTCs: http://forums.tdiclub.com/showthread.php?t=345887

    Hello OP and welcome to the VCDS forum.

    I have bad news ...........been here a few times.

    You will need to immediately test the reductant circuit & MAP sensor using WD. Please verify the harness is not damaged first or contaminated with urea or oil causing a bridge that damages the control module or from a shared track.

    When this happens it can cause the limp mode by damaging the EPC circuit within the controller as a result.

    It is possible the sensors are faulty and shorted causing this damage too or the FOD part #!

    Fuse installed inline added to the reductant & MAP sensor for each track will stop this from a future catastrophe.

    First off, THANK YOU so much for chiming in here so quickly. I really appreciate it.

    The G686 is located right on the AdBlue pump. I bought a new pump and swapped it, but the issue was not solved.......so I'm learning toward a wiring or controller fault. There was no warning or intermittent issues, this happened out of nowhere which seemed very strange to me.

    Unfortunately I don't have access to any wiring diagrams, so it's difficult for me to actually track this down myself. There is VERY little information on Touaregs floating around out there, do you by chance have a wiring diagram I could follow?

    I'll have a look at the fuses you mentioned when I get home from work this evening. Also going to try and check the grounds and battery cables.


    The first night I found these faults I went through an output test on the engine module and everything seemed to be functioning properly. After I went through all of this and cleared the codes on 01-Engine, none of them came back while the vehicle was starting and running for 5 minutes and then all of the sudden the check engine lights started flashing again and I got the same 2 codes for p204a and p0651. Since then I haven't been able to make the codes go away again following my same steps.

    Have you seen this exact issue? Or a similar one?

    I have ever seen so many "Malfunction 0010" codes in a scan before and I've owned VWs and Audis for 12 years now.

    Yeah when it comes to WD, I do have acces to them via the official VW ElsaWIN program. Sharing them publicly is a bit of a grey area. They are probably copyrighted but there is such a thing as fair use as well.

    For consumers and workshops, there is the ERWIN for WD: http://wiki.ross-tech.com/wiki/index...ir_Information

    YUP!


    Well my notes indicate you can also have an issue with the shared turbo charger module tracks on J724

    My money was on the Z102 which is the heater in that POS causing a back feed to the J623 from the sensor doing an internal short.

    I can understand it's a bit of a grey area, I wasn't sure what the policy was so I thought I'd ask. There is so little information available on forums and google for the Touareg I was hoping I would be able to get something to help.

    This MIGHT actually be the case Jack. So when I run through the output tests on the 01-Engine module, the only output that doesn't seem to respond is the turbocharger control actuator (can't recall the actual name for it in VCDS). So how would one go about checking this? I know when I pulled the engine cover off the engine last week I had some oil residue on the turbocharger and I noticed some soot on the turbocharger from a small exhaust leak I've been delaying fixing. Do you think this could be what's shorting things out and causing the issues??

    Also I felt I should mention that the very first time that I ran the output test after my limp-mode issues, the actuator worked. Now when I run it, nothing happens and it seems stuck in the wrong orientation because when I start the vehicle and it idles, it sounds different than it always has.
