Some warning lights have started appearing - specifically the tyre pressure warning, ABS, Park assist. Also the start-stop system does not function either. A local garage diagnosed a faulty tyre pressure sensor and changed it which appeared to initially sort the problem.
But now after driving some distance (so far this happend between 8 - 20 miles from cold) the same lights come on again - and after some further miles more serious warning lights come on - EPC, engine symbol (emissions), power steering, brakes, plus the speedo and gear display stops working. At low revs the engine feels noticably different though does not fail. Also brakes and power steering seem ok. The local garage say I should get a full diagnostics at a main dealer.
As stated above it always seems ok when first started from cold - very odd. Any suggestions before I go down the main dealer route. Model is Fabia III Monte Carlo estate - registered Jan 2018.
