Audi Cabriolet B4 (1997) - Key Fob

Hi all, key fob has stopped working for central locking at the same time as I was fault finding central locking issues with boot lid interlock and roof NOT opening beyond the first 50mm ish!

What I know:
1 the tailgate servo-motor interlock moves but is not sending correct signal so roof does not open. Have shorted out 2 wires and roof now opens 100%. Searching for a used part at circa £80.

Vacuum pump sounds ok is working and on my car does have an integral remote module.

Note also that ignition key can be pulled out with engine running, Not ideal and may have corrupted alignment with central-locking????

QUESTION - how do I confirm if fob is working or if I need to source a replacement vacuum pump? A new vacuum unit is available from AUDI at a cost of £660!

It may be that I need to focus on a replacement steering lock and 2 keys before looking elsewhere? So many questions, I need help please.
