Hi. We have got a 2000, 1.4 Seat Ibiza in at the moment, We have replaced the ecu, instrument panel and key from another vehicle, we have had to repair the second ecu as the customer had blown both up with charging the battery on 24v or connecting the jump leads up the wrong way, It now communicates with the snapon scanner, and KTS 650. and we have worked on several before and had no communication problems.
