D3 Telephone ECU

[Tinman]

Hi Guys, The telephone system in my 09 D3 has started to drop out when on a call. You can call back everything is ok for a while. Checked for faults and I am getting in the Telephone ECU a fault code U3003 Battery voltage. I was getting this fault before I changed my alternator and I thought it might go away with the new alternator installed pumping out more volts. Not sure whether it is a bad connection to the ECU or something else. Does any one know where this ECU would be located so I could have a look and see.
Cheers

From memory, it's behind the right hand (driver's side) trim panel in the boot.

Hi Dave, pulled the jack out but the only wiring I can see is for speakers and entertainment system and tail lights. Do I need to pull anything apart to get in there

Up the front end of that panel

And you need to pull that whole trim off to get to it.
