Hi
I have a 05 punto with 25000 miles, intermittently on startup there would be a steering failure, after restarting the engine it would go away for several weeks, ive since been on holiday for 2 weeks and trying it when i got back the steering fault would not go away after several restarts of the engine. I purchased a a second hand pump from the breakers same model (1077), fitted it all but now i have hillstart failre and ESP failure lights, tried driving it but the breaks keep applying and it wont rev, i dissconnected the battery due to taking the airbag off but cant see why it would cause ESp and hillstart failures the steering failure has now dissappeared though

any ideas guys??

The old power steering was quite probably ok.

Most likely it's a faulty battery (clue is in the post start faults and holiday lay-off).

All of these systems need a healthy power supply with no dips in voltage. Get the battery properly stress tested but 10:1 a good quality new one will solve the problems. Also remove clean contacts and refit the main engine/battery earth cable.

Junk the small cube battery case (if it has one) and fit one of these. You could save £30 and fit a lower spec but I think the extra is great insurance. Halfords also sell them for a bit more money.

The battery wont need the (small) case but do make sure you strap it down properly.
