VW / Audi TCU (Transmission control unit) Up for sale is a Working, in excellent condition VW / Audi TCM TCU ECU COMPUTER UNIT IS A - 096 927 731 AA TCM TCU ECU COMPUTER Unit comes with a 30 day functionality warranty! ---Always verify your original part number before buying, as there are several variants you may have!This Control unit came out of a recent crash damaged car, At this price buy it and throw it on the shelf if you plan to drive one of these fine cars for a while, or if you are in need now you probably won't beat this price. As always your best bet is to match the part numbers with the part on your original unit. These are located under the dash, near the center of the car, UNDER THE COWL (where the wipers sprout out of).Often times a fault with the TCU can mimic the symptoms of a faulty transmission. Don't replace that transmission when it might just be the electronic transmission controller. A faulty TCU can potentially cause a host of shifting & gear-change issues that may appear as though it's a transmission issue, however it's just as likely that there is a computer issue with TCU controlled cars. The price of a NEW TCU usually ranges between $1000 and $3000. Buy this from me for a small fraction of the new part price.
