Battery Change = reboot?

Hi again!

Just before I picked the car up last week it spent a few days with an auto-electrican as the wipers didn't work.

They advised that they had to reboot the car and as it had been on the forecourt for a few weeks that the battery wash't charged enough to handle the reboot. Furthermore they said I may have some warning lights appear if the battery didn't fully charge.

Once i picked the car up I had a 'motor control system failure' warning and the orange engine warning light was on. The next day they disappeared and all was well, unfortunately today they reappeared.

I can take it back to the garage and they will fix it but it's 60 miles away and a bit of a ball ache . Just wanted to know if fitting a new battery is straightforward or if i will need to do more reboots/resets etc?

Cheers again, Jiggalc

There is no such thing as a reboot/reset, appart from disconnecting the battery.....

Sounds more like you have a bad battery. And yes, it's a simple procedure to replace it. Just make sure you get the correct capacity & size.

A duff battery can indeed cause all sorts of problems however I wouldn't change it as a matter of course, the engine management light can come on for a whole host of reasons.

Providing the car is starting and running OK I recommend you either invest in a cheap OBD reader or software to read the codes. You may well find the problem is nothing to do with the battery.

MultiECUScan (google it) is a fine piece of software and the free version is good enough for what you want, you need a special cable to connect to the car's ECU, which is a socket behind the panel by your right knee.

You can also buy Bluetooth bits of kit that plug into the socket and you use an app on your mobile.

Good luck


Loose - not close, compact, or tight in structure or arrangement
Lose - to part with or come to be without, as through theft, accident, negligence, etc.

Have just ordered an OBD reader for 11 quid on ebay so hopefully will get to the bottom of the problem.
