Hi guys, i have finally decided to throw in the towell. My car will not start now due to my ABS ECU controller i believe (cutting the immobiliser in) and i have no choice but to replace the ecu part. Now, i cant communicate with my car at all via obd port at all, except the immobiliser system. Now, the question is, how will i know what code put put in my new abs pump? Also, would the same part numbered ecu but from a VW golf 4motion fit my A3 2.0tdi quattro? Part number is 7H0-907-652-A, if anybody can get one cheaper than Â£478 then please let me know! In the meantime i am considering buying this ecu DREHRATENSENSOR - VW GOLF V (1K) 7H0907652A · 7H0907652A RAR Erzgebirge from Germany Any help would be much appreciated guys, im 19 years old on cr*p money and dont deserve this! Thanks in advance fellas!
