Hi all,

My mum has a 67 plate Tiguan DSG 1.4TSI (2WD), had a code today and it effectively stopped driving. U0103 "Lost communication with gear shift control module A".
AA came out and it started driving again, however on the way home (AA van followed), it stopped driving again. AA had to tow her home.

It now drives again, with EML and this code. Bit reluctant to clear the code and drive again, as if it stops we're stuck (AA won't come out for a repeat incident). I am hoping it isn't mechantronics unit, but has anyone had a similar issue with DSG and any ideas?

Some ideas I have seen online are a new battery, which it had last year already, and mechatronics, or the module itself.

Only other thing to note is it had a sunroof leak earlier this year, which completely soaked the carpets. This lit the airbag warning light (passenger side), however a thorough drying out etc and clear of the code sorted this issue. Struggling to find information where this module actually is located though...

Any help would be appreciated, thanks
