Where is my tcu located please?

[Lhmort]

Afternoon all, It would appear that my tcu has started to fail (no Bluetooth/sos/aux in and speakers popping) I’m trying to find it to get the part number and order a new one but I can’t find it. The only instructions I can find online are for an e86 or a 3 series, can anyone advise please? I have the boot lining in bits and am about to give up and take it to the stealers…..

As you look at the boot from the back..LH rear bulkhead behind trim…you’ll need to disconnect a bit of trim and fasteners to get to it..

Thank you - I found a link to the manual that someone had helpfully posted in the problems section and I’ve got all of the trim off and ordered a replacement
