  • Wanted. Electrical genius.. Help with a V10 TDI Phaeton please...

    Chaps. Is anyone in the Worcestershire area a wizz with vehicle electrics.
    I have taken delivery of an non starting VW Phaeton V10 tdi.
    In short the car is an 05 plate with a genuine 59k on the clock.
    The previous owner used it very infrequently covering about 1k between Mots. However he left it standing in his dry garage for a while and it wouldbt start so it stood doing nowt for ages.
    I learned about the car so bought it cheap and had it recovered to my house.
    Having read up I purchased 2 varta agm batteries and rigged them up in the correct sequence.
    I got all electrics working but when I go to ignition the dash asks me to press the brake pedal. But on ignition there is nothing. If the lights are on they go off with ignition, suggesting the x relief relay is working.
    If I rig the jump cables up under the bonnet she turns over. But will not start.
    I've plugged VCDS in and got multiple codes as expected. However the common one is 01314 no comms with ecu.

    ​​​Most modules in car eg gearbox instruments etc say no comms with engine control 01314 also.

    I suspect this lack of comms is preventing the engine from starting/ cranking.

    Part of me just thought I'd scrap it/sell it spares or repairs.

    However the stubborn side of me wants to figure out what's wrong. I'd love to get it motd.. And have a go..

    So far I've checked all fuses. They are intact. I've got good 12.6 volts on both batteries.
    I've managed to get both engine ecus out (one for each bank) and pins etc look fine.

    I've checked the kessy in footwell, this seems to be fine. Eg no water or corrosion.

    In shirt I'm fine with oily bits of cars but electrics just confuse me most of the time. Especially on this thing.

    Is there anyone local to me who would be prepared to lend a helping hand with the electrics?
    I've got a few self study packs but if I'm honest it means little to me.

    Brake pedal switch?? (Newbie stab in the dark) Sounds more fundamental than that though!

    Good luck!

      Brake lights are coming on. However I bet there 4 wires to the switch. 2 for brake light circuit and 2 for ecu. I'll try bridging them..

        Quite a lot of info on the VW vortex.com site. Might be worth spending an evening reading up on issues other owners have had. My 10p worth - if it's been left for a while with a flat battery, the keys need 're coding with the car?

            Is it CAN or not? That age was around the crossover. If it’s CAN, I’d try some CAN sniffing software and see if you can see which module(s) are not transmitting data and go from there.
            Have you checked for rodent or moisture damage? Most common causes of issues during/after storage

              It is Can, there are a number of faults for Can.. But most of these appear to be due to missing the engine ecu. I was wondering if it was rodents although can't see anything.
              However everything comes on she just doesn't crank.
              I was wondering if it was the pyrotechnic fuse on the starter loom.?
              Tbh I was considering splitting the car for parts but seems a shame.
              Johne I'm in Redditch so don't want to put people out. Just need someone with a greater understanding than I..

                Tractor Dave. I have read loads. Lots of people have issues with the kessy system although on ignition the system tells me it recognises the key and allows me to remove it and select gears etc.
                My understanding is if kessy is goosed it won't aloow me to do any of this. I've physically checked it and connections and it's all fine.

                  Well good luck with her then. It would be a shame to break, sounds quite nice
