VR6Pete 1,455 Posted May 8, 2011 Report Share Posted May 8, 2011 Final stretch with my corrado, but come across an MOT show stopper..The ABS light doesn't come on at all, I've checked the voltage to the light which is 12v, I've also obtained a new light to ensure that it wasn't the actual light at fault...I've also got problems communicating with the ABS ECU via VCDS, and intermittently get 'too many communication' errors, I can hear the pump 'clicking' when VCDS attempts to interrogate the system, ive also obtained another ECU as my old one had badly corroded terminals from water ingress, the ECU is also getting a good 12v supply using multimeter on the ECU's plug..Are there any fuses / relays I should be checking? Or any other diagnostics I can try? Any help would be appreciated as I really want to get the car in for MOT soon Link to post Share on other sites
Gazbarber1982 3 Posted May 8, 2011 Report Share Posted May 8, 2011 What about a bad earth to the bulb? That would also stop it lighting. Link to post Share on other sites
VR6Pete 1,455 Posted May 8, 2011 Author Report Share Posted May 8, 2011 I've actually been unlucky, it just ended up being a blown bulb in the ABS light unit, unfortunately I did buy another one, but that had a blown bulb too! I'm going to try and find a new bulb and solder it onto the PCB...Also the comms issue appears to be VCDS, I tried vag-com 709.x and that was fine... It just freaks out when using VCDS, any idea where I can find a bulb from? Link to post Share on other sites
Gazbarber1982 3 Posted May 9, 2011 Report Share Posted May 9, 2011 Either maplins or rs components for the bulb. I've had it on mine before now where the bulb was ok but the circuit board had a break in the pcb. Just a drop of solder on the contacts fixed it. Link to post Share on other sites
VR6Pete 1,455 Posted May 9, 2011 Author Report Share Posted May 9, 2011 I've seen the bulbs on RS Components, cant see them on Maplins...will be ordering some later (min order 10) so will buy these, fix up my spair ABS lamp and sell it on + aditional spaire bulbs// I imagine they are fairly common across the VW range.Pete Link to post Share on other sites
VR6Pete 1,455 Posted May 9, 2011 Author Report Share Posted May 9, 2011 bulbs ordered... will have a spare ABS module once they have arrived and soldered to the PCB, will also have some spare bulbs too.. Link to post Share on other sites
