Unit returned for testing and as they expected found to be faulty with
all the usual faults they have. Kept informed by several texts of the
progress and unit very quickly returned with a bill for £145 plus VAT.
Refitted unit, cured the problem completely and car now back in service
and should be OK for sometime yet.

Seems this is the new way that older cars die off now with "electronic
problems" this one still mechanically fine at 150K miles not bit a bit
of rust anywhere, so good result all around.

No connection apart from being a very satisfied customer etc...

Interesting.

My Audi currently has a problem with the Airbag ECU which leads to the
airbag light being permanently on. We got it diagnosed and it turns out
that it's a fairly well known fault: in cold temperatures the EEPROM in
the unit can randomly flip bits and then it fails a checksum test when
it tries to power on. Theoretically a re-flash would cure it.

The problem is I'd need to dismantle the entire centre console to get at
it and then drive around with the car like that whilst it was being
repaired:
