Well I tried allsorts of manouvres - took me a few places to find a car park big enough!!
Brake pedal pushed hard until ESP and ABS light flash alternate
Drive at 13mph

then a steady 10mph whilst trying to do between quarter/half turn without hitting anything!
So if you saw some silly bu99er driving slowly around Morrison's car park doing silly turns, stopping then doing it again, that was me!!

For the first time since about October, my dash has no warnign lights showing

Thanks for your help Mike - helped me sort it and I've learnt a few things along the way
