VW T6.1 recommended electrical specialist

[BlakeyG]

Hi, I'm getting a few errors on my van T6.1, amber triangle and says leave in position P when opening doors or put lights on, basically waking up the communication, everything is working fine!

• identified a real antenna circuit fault (B110311) digital arial ground (GND) I've taken the mirrors off and cleaned both grounds.
• isolated a communication interruption fault (U111000)
• control module fautly B20004

Can anyone recommend a garage or someone who knows about electrics not too far from Dudley, West Mids !

Cheers
