Seem to have load of electrical problems with the families Punto's at the moment.

My niece has a 53 Punto which has been flattening the battery recently, and throwing up spurious warning lamps on the dash. Also she swears that she has seen the courtesy light and sidelights on when they shouldn't have. She put it into her local garage, who got a auto electrician to have a look...his diagnosis was that the body electrics computer was faulty and a new one is required and to be programmed. Which would cost within the region of £600.

I've never heard of this...but I belong to the analogue world!

Does anyone know about this type fault, is it plausible, and is there a cheaper fix? as this could be the death of a perfectly good running car.
 
HIGHLY unlikely to be the computer to be honest. They are just saying that its the computer just so you scrap the car as obviously you're not going to spend £600 on a 10 yr old car.

I don't know this fault personally but it sounds as if you are getting an electrical feed through a chaffed wire or a "Short" for those who like laymens terms. The good thing about the punto's is that all the electrics pretty much all congregate just to the right of the steering column (Actually where the aforementioned ECU is located).
 
Thanks guys...what's the function of this electrical body control module? Is it a switching unit for all the electrical services and does it incorporate the Immobiliser?

Bad earths...where the most likely location? engine bay and boot?
 
The plot thickens...the car had been stolen and the standard radio nicked. An aftermarket radio and a Toad alarm were fitted with a central locking interface.
It transpires that this is about the time she started having spurious warning lamps lit and a flattened battery, the alarm would "false alarm" from time to time, and was changed for a new unit but the false alarms continued.
Would it be wise to disconnect the radio and alarm system to see if the problem persists.

Yup, i'd take it from there.

I know from the cinq that when the stereo wiring isn't quite right, everything dash related goes a bit odd, wouldn't shock me if the punto was the same.
