Hello guys, An acquaintance has problems with his Phaeton 3D 3.0 TDI. Doesn’t know exactly which year of construction that was 2006 or 2008. Everything works as far as normal only some things are not available: – Navi, DSP, phone and further are described as not available when you press the button on the Navi. -Navi CD can not be removed from the drive but can also be a broken eject button. -Radio runs but no sound. The following errors according to VCDS available: Address 19: Diagnosis interface: 01305 Databus Infotainment -> 014 Defect 01044 Control unit incorrectly coded -> 000 – – – 00470 Group Databus Comfort in single wire -> 011 Interruption The same errors are also shown under the address 17: Control panel insert. ————————————————————— Address 08: Climate/Heating plate. 00462 Control unit for seat adjustment with memory, rear. No signal/communication However, he has no seat adjustment in the back? dio, Navi etc appear under VCDS as not reachable. He bought the car with the problem..
