Battery/ Alternator nightmare!!

Hello,
I've been browsing the forums for a while so decided it was time to sign up!

I have had an issue with my battery/ Alternator I'm after some help with. It's a 320d lci 2011

So on the drive to work the other morning the red battery symbol came on (intermittently at first then solid on) it had been particularly cold this morning. Left work and car wouldn't start (dash lights on and would lock and unlock etc).

Day after I hooked car up to charger to see if it would charge and start. The battery charger was showing error tested on my mates battery and charger worked. From that I assumed I needed a new battery.


I usually do most of the work on the car myself however as the battery needed registering I decided to go with local specialist. So I hooked the car up to the works van via jump leads, at first I was just getting a clicking noise, nipped to the toilet and tried again and car cranked but slow. Started donor vehicle and then my car fired up, put radio and heaters on etc (to avoid power surge) and disconnected jump leads. I then drove the car 15 miles to the garage no issues other than the red battery light.

So after the specialist got the right battery they fitted it and tried to start... The car was then making clicking noise again. They then were messing around with it and the car started (possibly with booster pack). The mechanic then said it's the alternator that's gone and it needs a new one.

I decided not to leave car and drove it the 5miles home (no red battery symbol on dash anymore). When I arrived home I turned car off and tried to start again and it made the clicking noise and no life.

Dies it sounds one the alternator has gone? I'm going to run a multimeter over the battery tomorrow and when the car is running too but im interested to see what everyone's opinion is.

Sorry for such a long post and I appreciate any help!

The red battery warning usually means there is a problem with you battery charging system not that the is a problem with the battery. I would assume the alternator is most likely the issue. Easiest way to test it is to start the car and measure the voltage at the battery... it shoudl be at least 13.6Volts+ with the engine running. If its anything lower the alternator is not working properly.
