Hey,
I'm getting an intermittent screeching/grinding noise when trying to start my 56 plate 1.2l Fiat Punto. It starts 99% of the time, however, that 1% it doesn't and I have to wait a few minutes before it will start.
I've done some research on the forum and found a similar thread where a user had the same exact problem. It was suggested by another user that:
'If it's screeching/grinding during cranking- it'll be the starter motor not engaging. Aux belt squeal will always happen after start-up.
If it attempts to crank, stops, then cranks again before starting/making the noise, it needs the ECU software update to correct the low battery voltage issue affecting the starter motor relay. Alternatively for now, fit a new (uprated) battery. The standard 1.2 battery can suffer from a large voltage drop once it gets old, even though it will always appear ok. A larger capacity one will cope better and not suffer the same issue.
The only problem is if the fault has been occuring for a while, damage will have been done to the flywheel teeth and the issue will just get worse, even with a new battery and the ECU update.'
A new battery seemed to work for the original user with the problem.
My question is: what new (uprated) battery should I purchase? Ideally I'm looking for the cheapest option.
The forum won't allow me to link to a battery that I have in mind but I was looking at the cheapest option on eurocarparts.
Lion Battery (Battery 202 3 Year Guarantee)
Product Code: 444772021
Would this work? Is it 'uprated'? Will it fit?
Sorry if this is a simple question. It's my first car and I haven't a clue!
Thanks.
