Hi all, I recently bought a gt tdi 140 off my sister and I must say, I love it. But we are having one issue. 1st thing in the morning it starts fine but then after that it seems to crank over for a while before it will fire and the battery starts to sound lazy and die. Now I know what you are thinking, dodgy battery! But I've but the tester on it at work a few times now and always shows as good. A lad next door is having the same trouble with his a3 140 tdi. He's been told about problems with starters, but i'd like to find the problem before chucking parts at it!
Any ideas?
maybe heater plugs? but would of thought it wouldn't start in the mornings then?!
Many thanks
Ben.
