Audi TCM Up for sale is a Working, in excellent condition Audi V8 TCM. 441927156Q Bosch part number 0260002199 ZF part number 0501004142 / 441 927 156 Q Bosch part number 0 260 002 199 / ZF part number 0501 004 142 TCM TCU ECU BOSCH COMPUTER Unit comes with a 30 day functionality warranty! This Control unit came out of a 94 Audi V8 Quattro, which is the 4.2 liter motor (the big one) . At this price buy it and throw it on the shelf if you plan to drive one of these fine cars for a while. As always your best bet is to match the part numbers with the part on your original unit. These are located under the driver side knee bolster.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 BOSCH TCU controlled cars. The price of a NEW Bosch TCU usually ranges between $1000 and $3000. Buy this from me for a small fraction of the new part price.
