contorted fungus 0 Posted September 7, 2009 Report Share Posted September 7, 2009 right here we go. got a 97 vr6 with an abs fault it reads as hydraulic pump not in parameters have changed pump unit for a known good complete unit but it has a different letter at the end of the part number now the bloody thing keeps the handbrake light permanently on. (argh its making my head hurt) is there a relay for firing the unit that i need to change coz i couldn't find any control boxes under the dash (its all apart at the mo) does anyone near me have vag.com to help fix/clear fault codes help please i miss driving it ;( Link to post Share on other sites

craggsy 91 Posted September 10, 2009 Report Share Posted September 10, 2009 Ross tech will supply a genuine lead that unlocks the full version of VAGCOM. You cannot get a full version and use an ebay lead Link to post Share on other sites
contorted fungus 0 Posted September 10, 2009 Author Report Share Posted September 10, 2009 how come it won't work with an ebay lead Link to post Share on other sites
craggsy 91 Posted September 10, 2009 Report Share Posted September 10, 2009 it needs to be a registered lead to work full version, can use it still with an ebay lead just not fully Link to post Share on other sites
Rikki 2 Posted September 10, 2009 Report Share Posted September 10, 2009 It doesnt work because the part number is different! What part num came off your old and what is the new one? Link to post Share on other sites
contorted fungus 0 Posted September 21, 2009 Author Report Share Posted September 21, 2009 they both had the same numbers apart from the last letter however i took it to the dealership and it should have a unit with 3A0907375A on it and my two end with 379 both for sale if anyone needs one Link to post Share on other sites
Rikki 2 Posted September 22, 2009 Report Share Posted September 22, 2009 So its a different part number then. Vw usually superceed part numbers with a later letter but on mk3 abs pumps. 3A0 907 379 A has changed to 3A0 907 379 C and is for cars up to chassis wvwzzz1HzVW123000 (approx 07/96 production).3A0 907 379 E has changed to 3A0 907 375 A and is for cars from chassis number wvwzzz1HzVW123001.
