Edgeyboy 3 Posted November 28, 2013 Report Share Posted November 28, 2013 Ive changed all the sensors on my abs system, yet my abs light is still on! Upon further inspection, i discovered that controller on the side of the pump, was unplugged. But when i have plugged it back in, it still doesnt give me any response to my vag.com. Any ideas?

shawy 3 Posted November 28, 2013 Report Share Posted November 28, 2013 Sounds like pump is faulty .. or no power to the abs pump.. If its disconnected I would go with the pump being goosed.Mk 3 or 4 Link to post Share on other sites
paceo 22 Posted November 28, 2013 Report Share Posted November 28, 2013 (edited) is it a mk3? i have a abs pump buddy thats fully working. or it could be the abs ecu thats buggered! is your ecu under the passenger rear seat? Edited November 28, 2013 by paceo Link to post Share on other sites
ssaunders 199 Posted December 2, 2013 Report Share Posted December 2, 2013 hi, there are hundreds of threads regarding the ABS light issues. it seems that a lot of VW/Audi's from about '93-'04 have the same problem with the actual controller (sits on top of the pump) i had the same and got my controller remanufactured by BBA reman (google it) about 2 years ago and no more problems. if you use another unit i believe you need to have it coded to your car.good lucksteve Edgeyboy 1 Link to post Share on other sites
Edgeyboy 3 Posted December 5, 2013 Author Report Share Posted December 5, 2013 Its a mk3 and not sure about the location of the ecu as im not really that hands on with this car( used to be a vauxhall person but fell in love wi the mk3 vr6 golf) erm well ive been eyeing up a replacement pump and controller on ebay...the part number matches apart from the last letter.... Mines A an the one on ebay is B. will this make a difference? Im totally at a loss here an not sure what to do.Any help would be great guys thanx Link to post Share on other sites
shawy 3 Posted December 5, 2013 Report Share Posted December 5, 2013 Normally the abs ecu is incorparated in the pump. U can tell by the plug on the pump .. how many wires.. Not clued on mk3 golfs but its very rare its seperate.. Link to post Share on other sites
VR6Pete 1,455 Posted December 5, 2013 Report Share Posted December 5, 2013 Another thing to check is that there is a separate wire that runs from the obd2 socket to the ABS ECU. I had an issue on my mk3 where the ECU was not communicating with vag com and it just ended up as the wire had snapped, however as the ECU plug has been unplugged, would suggest that there could be a fault with the unit. As mentioned, you'll need to get your hands on an ECU and ABS pump as they are "matched" so get looking at some breakers Club Chairman Link to post Share on other sites

Mine has the same problem & as it's going in for the MOT at the start of February I need to sort this.... Did the come back with a price & would you mind telling us? I have a replacement ABS pump/ecu but it hasn't been tested so I think it would be safer to send the original away for remanufacture. Cheers Jamie Link to post Share on other sites

Surreyvr6 199 Posted January 3, 2014 Report Share Posted January 3, 2014 I'd be keen on knowing the price too, hoping new sensors will sort out my light though but would be good to known a price if not Sent from my iPhone using Tapatalk Link to post Share on other sites

If it's just the orange one then it's most likely the sensors but if it's both then it's probably the pump/ecu that's gone Link to post Share on other sites
Surreyvr6 199 Posted January 3, 2014 Report Share Posted January 3, 2014 Only the abs light, that's good to here, thought it's more than likely a sensor issue, last time I changed them it solved it for a while. Was typical my light hadn't come on for ages to then decided to come on when I was getting it mot'd lol Sent from my iPhone using Tapatalk Link to post Share on other sites
ssaunders 199 Posted January 7, 2014 Report Share Posted January 7, 2014 Hi, it was a couple of years ago but i believe it was about £160'ish (mine only lit the ABS light) easy way to check the rears is VAG com, check which side is error'ing clear the fault and lift the rear seat, both the sensors connect here swap the left for right (and vice versa) recheck vag com and if the same side still errors its the controller, if the fault changes sides then likely the sensor.Give BBA a call for pricing 01634 687222 their website says they keep some in stock (would need coding though). i would VAG com it first to get the correct part no. as wellgood lucksteve Surreyvr6 1 Link to post Share on other sites
Edgeyboy 3 Posted January 14, 2014 Author Report Share Posted January 14, 2014 hiright i had both lights come on on my vr so ive sent the pump/ecu to bba reman, which may i add were fantastic, and they got back to me in a matter of days [ 4 including weekend] and they have tested it and have said its fine, so am now stuck as to where to turn next.....price for a test was £35 and £20 to have it returned next day which i think is fantastic value and service....if anyone has any ideas as to what the problem could be, then please im in turmoil...thanx guys Link to post Share on other sites

Edgeyboy 3 Posted January 15, 2014 Author Report Share Posted January 15, 2014 this will prob sound dumb but if i do need anythin off ya will it be the same as a vr loom?#clueless Link to post Share on other sites
Marneus 78 Posted January 15, 2014 Report Share Posted January 15, 2014 When you vagcom it does it show "Terminal 30 low voltage"?It didn't show any ABS faults for mine when we ran a check but it did show Terminal 30 low voltage, with a bit of interweb surfing this comes back as a fault in the ABS ECU..... I suppose BBA will have checked that though?It was so much easier when you could rip the whole ABS system out & still get an MOT! Link to post Share on other sites
Edgeyboy 3 Posted January 15, 2014 Author Report Share Posted January 15, 2014 hahahah ye i know...well the fact that it failed coz the light stayed on an nothin mentioned about the ABS not workin at all is a piss take really??!! Link to post Share on other sites
