Later, upon reflection I was a little more concerned as we had experienced(along with many parts of the country) much heavy rainfall. Next day I started the car, and my attention diverted by operating a powered roof that was 'playing up' and operating sluggishly, when I looked at the dashboard it was to my horror still lit up like a Christmas tree of warning lights.
So, even though the floor and seats in the car were bone-dry, rainwater had clearly got into/under the dashboard and some damage the result. The ECU, ABS lights were just 2 of the warning lights that warned me to stop the car and get to a garage or auto electrician asap. Last week was abysmal in terms of weather and this caused me to abandon all thoughts of attempting to limp to a garage, my rationale was that a damp atmosphere would exacerbate the situation.
As happens in Beard life, my thoughts turned to potentially swapping the car, but fortunately this came to nought, the car in question is relatively worthless, but a gem (27k miles 2010 Audi TT convertible, Autotrader value < £6k)
To end this tedious tale ... GOOD NEWS...
Exactly 1 week after last trying to use the car I had to move it a few yards, lo and behold NO warning lights were on the car, and after using it on a short journey stopping and starting it a few times the problem seems to have gone away.
Trivial stuff I know, nothing profound, but a very timely warning of what could have been a major expense , fuses,relays,ECU ....£Hundreds even Thousands and lingering doubts about future reliability.
