Does anyone know, please, the reasonably precise location under the left side floor of the Telephone ECU?

It's been a bad month for the A8! The variable life service needs doing, the thermostat's playing up and now the phone ECU has packed up after working fine for 11 years. [A VCDS ECU scan shows 77 Telephone "Cannot be reached" and shows the optical bus and electrical bus statuses are "Error" - MMI comes up "Telephone not installed"].

It's a bit of a kerfuffle to get the seat up, the trim off, carpet folded back etc., so as I'm almost certainly the last owner of the car, I'm thinking of just cutting a flap in the carpet.

So, if anyone's replaced this ECU before, can you confirm:

a) Where the unit is [I guess it's a box about 10" by 8"] in the floorspace
b) That there's no connectling cables lurking inder the carpet that I could cut

Thanks - Julian
