2010 C30 2.0d alternator - 120A or 150A?
Does anyone know which alternator is likely fitted to a 2010 C30 2.0d?
Pretty sure it's on the way out and wouldn't mind trying to replace it myself, but I've heard that: a) If it has a 120A alternator, it should be upgraded to 150A b) This would require a software update to the car's ECU That means that I probably won't be able to do this job myself if it is a 120A. Thanks for any help |

Thanks for your input.
The first symptom which made me check the alternator was a whining noise at low revs. Then checked the battery with a multimeter: 12.2V when engine off and cold (not driven for 5 days), and slowly climbed up to 14V when idling. I then put all of the lights and cabin electronics on and it struggled to get above 12V. Alternator was also too hot to touch after a couple of minutes of idling. Do you think that could still be one of the other things you mentioned? |

That what happened to mine, very hot and making a noise on start up. Vida indicated 150 amp unit and you could also read the label on the old one.

Thanks for your advice guys.
Replaced the battery today and the situation didn't improve. On the plus side, I managed to spy a label on the alternator which said '12V 150A'. Looks like I should be able to replace it myself. Any tips? |

if the bolts look corroded, soak em in penetrating fluid day before. Also, check pretensioner or aux belt. If doing alternator, maybe do that at same time.

Check prices from a few places before buying.
I saves around £50 buying the exact same part from carparts4less as opposed to ecp
