Audi A3 DSG 6 speed gearbox

[car2tref]

Went into limp mode so had mechatronic ecu checked, no fault found, changed gearbox including mechatronic box and now it works fine, apart from Manual side of gearbox and the paddle controls no longer work, both gearboxes are HLE so dont know what to do to get the paddles/manual working again, anyone got any ideas?

Problem with the paddle switch? I would have thought when it went into limp mode it would have given an error code to almost pin point what the problem is. If the transmission is shifting automatically, it would indicate that it is mechanically sound and you have en electrical problem. Probably check things like connectors, plugs etc. It might be something daft and seemingly unconnected like a duff alternator

When you say not working, what actually happens when you shove the lever across to the left? Does the dash display the gear or a D?

The paddles might just need coding, I'm not sure if the coding to say it has paddles is in the mech unit or somewhere else.

Does sound like a coding issue if they were working before. Into a dealer or specialist for base settings and adaption.

Go back to whoever fitted the box and get them to deal with it.

Saying that, it's not clear rom your post. Was the box sourced second hand?

Ok, hmm, when i select the manual gearshift, it shows the gaears going up and down but it doesnt actually change but if I use the paddles it doesnt show it going up or down. Coding sounds interesting, how though?!

It does not go into limp mode now, since i changed the gearbox but it wont allow the paddles to change gear and when I use the manual gearbox lever selector, it shows the gears going up and down but it doesnt actually do it!!

second hand box, yes but it works really well in auto mode, no more limp mode after driving for 200 miles!!

You guys are great, thanks for the help, I have no idea how to reset the electronics to enable paddle shift and as the car has been in a garage for 6 months now, I just want to get it out and drive it, spent a total of £1500 trying to sort it so far!!

coding issue, sounds like a Main Dealer ripoff time to me Aaaarrrgh!

Spoke to a specialist who says this cannot be recoded, have to reinstall my original mechatronic box and hope that cures it?
