Law6on Posted December 18, 2019 Share Posted December 18, 2019 Hi all, new to this so give me a chance... Just brought a 2014 Audi A3 1.8TFSI. It’s got 57k miles on it and is cat n. It’s also running big power - bigger turbo intercooler turbo back exhaust etc etc (360bhp ((180bhp standard)) ) Found out that the gearbox has been replaced with a 7 speed 2016 gearbox code RRF (car should have PYV). According to TPS either box is fine for the car but apparently the mechatronics is not meant for the car (Need to get part number and code for this) The gear box fitted has a sensor zip tied to it which is the gearbox speed sensor. They have done this as the gearbox has no cutout for the sensor to be placed in... I have no warning lights on the dash but a lot of fault codes come up when it’s plugged in (will post codes below) and when driving normally the gearbox is fine however when you put your foot down it often won’t change gear, usually revs to around 4k and then it’s as if you are hitting a rev limiter it just won’t shift up until you completely let off. Then when you put your foot down again it will rev out shift up and then tend to do the same in the next gear however strangely sometimes it shifts with no issues at all. My garage is telling me to change the mechatronics unit to correct one however the part alone is £1400 and I didn’t even bother to ask for a labour quote. I have no idea what the best way of going about this is or how to fix the issue hence coming here for advice. I was wondering if maybe there is a way of mapping the sensor out as if they make the gearbox without the sensor hole they must run fine without one? Any advice or pointers in the right direction is massively appreciated!
