Mot insurance and tax

[Terpe]

I had the dreaded sensor problem-Abs light on and off,nearly had to but £600 ecu unit but luckily was traced back to faulty wiring (a common fault) cost about £60
You are all lucky as I have to have 2 compliance mot tests a year and my insurance is £1000

I've changed my rear off-side sensor twice but still it's happening.
I can't continue 'ad infinitum' at £300 a pop.....

Like everything in life .....timing.
Hope I'll be lucky.

I've tried plenty of non-dealerships but it seems there are always issues with diagnostics.
Had the wiring checked but no luck.
