Hi All. Just after a bit of advice..... My 2ltr TDCI battery light came on last night along with a whining noise from the engine. Thought Alternator straight away. Checked battery charge from alternator via diagnostic page and it was only at 11.8V. Compared it with a mates this morning who's is at 14.4V. Car got to work ok but when it was time to come home......it struggled to start with central warning light flashing. ABS and ESP lights came on and no front screen heating. Got caught in a bit of traffic and lights switched off then on again. Radio went off and then came on again. Fun, Fun, Fun. So my thinking is that the whining is th brushes in the alternator worn so not charging and supplying juice to me motor!! Just wondered if anybody has had anything similar or if you are a car techie kow if my diagnosis it close. Cheers.... Newbie Jonny.
