The transmission saga comes to an end (hopefully). Wow, after the 4th removal I think I have the DCT sorted! To recap, the first time, which started this thread was after I got the 5A41 Pressure Sensor, Clutch 1 DCT fault. This occurred back in May, I pulled the tranz and replaced the Mechatronics with one from a guy on Ebay who offered used ones coded to your car. Put it in and the pressure Sensor fault was gone but now I had several new faults (12 to be precise). The Ebay guy offered me another Mechatronics so out she comes again (#2). After the second replacement Mach, I am down to 3 faults, 5A73 , 5A58 and 5A76. The Ebay guy goes dark, but I’m starting to think the twin sensor behind the clutch could be the culprit since 2 of the faults are directly tied to it. I bite the bullet, and order a brand new sensor and the trans comes out again (#3). I carefully replace the sensor and inspect the wiring harness for faults. At this time I also replaced the Transmission to engine wiring harness for good measure. Everything goes back together and I’m left with the exact same 3 faults. Ok, so I feel I’ve eliminated about 90% of potential issues so I just start looking for a good low mile (relatively) replacement DCT. Oddly I find one somewhat local for a good price and a 30 day warranty. Picked it up week before last and installed with fresh filters and oil (#4) . It was from the exact same year and model car as mine so didn’t bother with coding. Fired her us and bam! No more transmission codes and shifts perfectly!
On the plus side, I’ve gotten very good at removing and replacing the transmission, and feel I understand the internals very well. On the negative, I purchased a butt load of filters and DCT fluid, not to mention the sensor and used transmission. Anyway, I always hate when a thread starts but often is not resolved, so I thought I would close this one off on a successful resolution. Thanks to everyone who helped and offered advice! |
