Alternator warning light
Hi guys, I'm hoping someone can help.
I've got a 2006 1.9JTDm 159SW. A few weeks ago the alternator gave up the ghost, fortunately it's under warranty from the dealer so it got changed FOC, when I picked it back up the alternator warning light still came on, if you turn off the car them start it again it goes off and stays off. Dealer said he'd seen it before and it was a starter motor issue. I can't see how but I let him have the car back to fix it (under warranty).
It's had a new starter motor but the same thing keeps happening and they've had it for nearly a week now.
The alternator is putting out around 14V and the battery was brand new just before the alternator was replaced.
I'm stuck and so are the garage.
Has anyone had this before or know what's causing it?
