Vauxhall Tigra abs

Best to get the codes checked ,and alternator checked that it,s charging ok,There is a specific code that,s generated if the alternator is the cause.

If the ABS light was on previously , changing the battery wont cure it , more likely to be faulty sensor.You will have to supply more info i.e is the car turning over ?What do you mean exactly by "car failed on me" What engine is in car?

The car wasnt turning over before i put the new battery in, now its doing it again

If alternator not charging it will knacker/drain new battery .Simple two min job to check alternator output with a meter .

Agree ,best way forward is to check charging,and earth.

as above check battery connections and engine earth lead abs will probobley be a sensor or abs ring need to visualy check rings for damage or contamination ie cv boot split if all looks ok scan and replace sensor

just another point if engine not turning over have you checked starter motor
