I have 1.8 Toyota Avensis Vermont.
Both engine block light and ABS light on constant 
Engine block light went off after being diagnosed via computer but came on again a couple of hours later.
The ABS light on and cannot detect exact fault - showing defective ABS Pump now thats an expensive job.
Would disconnecting battery for period give temporary solution ? Want to get this through NCT Irish equivilant of MOT on this Thurs.
