Thanks for the comments, both of you. I shall have a closer look at the headlight.

I've run the VCDS diagnostics and get the following for afs system ------------------------------------------------------------------------------- Address 55: Headlight Range (J745) Labels:. 5M0-907-357-V3.clb Part No SW: 5M0 907 357 F HW: 7L6 907 357 C Component: AFS-ECU H04 0111 Revision: -------- Serial number: -------------- Coding: 01C600003F000000 Shop #: WSC 33361 790 00999 ASAM Dataset: EV_HeadlRegulVWAFSPt 002016 ROD: EV_HeadlRegulVWAFSPt_VW46.rod VCID: 372B20CE6FCE78E3829-8062 Subsystem 1 - Part No SW: 8U0 941 329 HW: 8U0 941 329 Labels: 3D0-941-329.CLB Component: LeiMo links H01 0005 Coding: 8E0000 Subsystem 2 - Part No SW: 8U0 941 329 HW: 8U0 941 329 Labels: 3D0-941-329.CLB Component: LeiMo rechts H01 0005 Coding: 8E0000 1 Fault Found: 5279249 - Signal Line for Position Sensor for Right Swivel Module C108E 11 [008] - Short to Ground Intermittent - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 27 Reset counter: 143 Mileage: 124071 km Date: 2020.11.26 Time: 11:49:22 Can anyone advise me which part is at fault? Is it 7L6 907 357 C, which seems to be a control module? Is this easy to replace?

Thanks langers2k. I seem to have plugged the dab into the gps then. I'll have to get a dab adaptor.

I've now fitted the replacement PbA VW8128V unit. Everything seems to be working ok. Only one slight problem I've met. There were 3 cables connected to the columbus plus the quad lock, one with a white double connector, one with a black connector and one with a blue connector. I've connected the white one to the double space and the black one to the gps using an adaptor and the gps seems to work. I haven't connected the blue one as it didn't fit where I thought it would. What is the blue one for and is there an adaptor for it?

Thanks. I'll carry on and get one then, to replace my temperamental satnav.

I'm considering replacing my columbus with a PbA VW8128V, which seems to be the replacement for the VW8028V. From what you have written above, the installation process looks reasonably straightforward if you have all the necessary equipment to hand. One question I have is that the Columbus is programmed in to work with the car's VIN, do these replacement units need to be programmed in the same way, or do they just work automatically?
