Hi, wife has just got a 2012 2.2td and alternator is not charging battery, only had the car about a month so very irritating as just out of warranty. Bought a new battery as well and it has discharged that. Both batteries recharge fully on the home battery charger so looking to replace alternator this weekend. Did you have to remove the air box to get to the aux belt and alternator? I can't see it from top down but can see the belt running the AC pump...
