Gtv starting problem
I've got a starting problem with my 2.0 GTV, and any advice would be very welcome.
Ususally the starter turns the engine over fine and it starts immediately. But occasionally the starter will struggle to turn the engine over, in the same way it would with a flat battery, and it just manages to start. But then the next time I start it it's fine again. There seems to be no pattern to it, but it does seem to happen more often when the engine is warm.
The battery tested out ok, as did charging. The battery leads are securely attached.
Could it be a poor earth connection somewhere, starter going bad, or a battery just not up to the job maybe? Battery is about 3 months old Bosch S3005 56Ah, rated at 480A
Thanks in advance
