The altenator is a pretty easy change unless going from a 120amp to a 150amp as you should have a software update done (by Volvo) to tell the car it now has a 150 attached.
A good search will get a Genuine Volvo/Ford altenator for approx £150 and then any garage can fit for 30min labour = <£200 and certainly no more than £250 should be paid. A couple of Links for those looking 1.8 Petrol S40/V50/C30 1.6 / 2.0 Diesel |

2005 Volvo S40 T5 Problem
My daughter has a 2005 S40 T5. The alternator went out and the "Power System Service Urgent" warning appeared on the dash. I had the alternator checked at a local alternator repair shop and the diodes and regulator were shot. I replaced the alternator (Denso 150 amp) with another one of the same type and amperage. They were identical units. The battery showed as good and the car has been running fine for about four months. The Power System Service Urgent warning on the dash never went away and the battery icon is illuminated. I had the battery checked at Autozone by a friend and it showed a little weak so I replaced it too. The warning on the dash is still there as well as the battery icon. I had the alternator checked and it showed as good too. With the car running, I checked the voltage at the alternator B+ and ground and it read 14.6 volts. At the battery + Post and ground the reading is 13.99 volts. The old battery had leaked some and there is a lot of corrosion under the battery housing. I am going to check the ground connection at the engine block to make sure it is clean. Could the .6 -.7 volt drop on the Alternator B+ to Battery + Post cause the warning light. Could I temporarily add an extra wire from the Alternator to the battery to see if the voltage would increase at the battery? What is the minimum gauge wire that should be used? I want to see if the warning would go away by raising the voltage. I have read the codes with a scanner and there are none. Any assistance with this irritating problem would be greatly appreciated !!!

Just reading a few of these posts, would i be right in thinking that any swap over of the part....especially an upgrade to a 150amp part, fails to remove the warning light. Forgive my ignorance but would this be due to this software upgrade, which i can only assume has to be carried out by Volvo or have i got that wrong. Needless to say, i am none the wiser on which pattern part my vehicle requires, as my car is the other side of the county and i've got no hope of my better half risking her nails and hair, looking for what part i require.

If you ring a Volvo dealer with your Reg or VIN then they should be able to tell you what your car left the factory with (120 or 150A). OEM part would be a Denso unit.
If your in doubt then opt for the 150 then at the very most you'll just require a software update once you've got the car running again. If you have the message and fix the broken part then the message should disappear. HTH. |

He was very cagey about giving me a part number as they supoosedly change to regularly to be accurate.......surely everything points to the Denso unit on Europarts for £136.00....once the surcharge is taken care of http://www.eurocarparts.com/ecp/c/Vo...a68aec6&000012 |
