The abs light in my 2012 1.2 litre i10 is staying on . The battery , fluid level and fuses are ok. The car has been sat on the drive for several months in rain etc and hardly driven for 12 months . The car has only done 7,000 miles in total Is it worth getting repaired as I assume it’s a sensor or main unit fault or should I trade it in ? Part ex value is only around £2,000 . Any thoughts please ?
