Title: 2000 Audi A6 quattro 4.2l Post by: shawn1978 on July 20, 2016, 09:18:24 AM Ok hello everyone I'm a new register but have been here for months just decided to register, O.k I have a 2000 Audi a6 quattro 4.2l and I did the 6 speed swap did the clutch wiring, finally got my ECU back after 3 months Put the ECU in that I got back from Vagautowerks and the car just turns over and want start but starts with my Automatic ECU ? the ECU that I got back wasn't the one that I sent? But I on the sticker it says S6 Conversion, now my question is do I need to get rid of the 2000 harness and get a 2001 harness are keep the 2000 harness in? can someone plz help me out it would be greatly appreciated..

Behind the cluster you need to make sure. No matter what I do I'm getting injections 2 & 7 open circuit?? but there working fine Verify that Pin 54 of the ecu goes to connector a180. From there it goes to the blue 32 pin plug on the cluster, and connects to pin 3 which is white and blue. Verify continuity between these two pins to ensure the ecu receives the proper VSS signal! The on the ecu plug on the ecu side, large plug remove the wires from pins 30, 47, 48, 81. These are the non CAN wires to talk to the ic. If you don't remove these, the car will not start and if it does it will run like crap The wire in pin 23 needs to be moved to 19. That is cyl 2 injector which is different on 01 ecus You must supply power to pin 21 on the large ECU plug. The 2000 ecu has no wire here, as it didn't have an immobilizer. Now, the small plug on the 2000 ecu. pin 115 has a large wire going into it. Follow it down till it splits. Those are cam adjusters - ground signal trigger. Bank 1 (passenger side) has to go to pin 115 and bank 2 (driver side) goes to 120. Basically the 2000 runs both cam adjuster grounds from one pin, we want to split them to both pins like the 2001 ecu has. If you don't want to do this, I can remove diagnosis in the flash, there are no drawbacks to doing this. Pin 104 ecu side, small plug needs to go to 48 on the large ecu plug. Intake manifold changeover valve. Title: Re: 2000 Audi A6 quattro 4.2l Post by: nyet on July 26, 2016, 10:50:02 AM I have fixed your post.
Please work on being more detail oriented, or you'll never have any success tuning :P |
