So, the day after sailing through it's MOT, my alternator packed in.

Driving along, muted the radio as it sounded like a mix between either stuck viscous fan/knackered supercharger/bearings in Alternator/belt tensioner.

Pulled over and turned the engine off, opened the bonnet and got the "hot" smell.

After some time i restarted it, same noise... BONG BONG BONG... Transmission Fail, HDC Not available, Gearshift Position Limited Gears....

Got a multi-meter, Battery on 10v, with engine running, 7v.... Ah...

New Alternator on the way then Might as well do the belt tensioner at the same time I guess!

I'd say it must have been on the fritz for a while as the battery was only put on last year. Fortunately I had the old battery at home that had been on the CTEK so I stuck that on and drove somewhere safe it will stay there until I swap the parts.

As soon as I put the old (new) battery on it the IID tool was able to clear all the faults.

Suppose it serves me right for being smug about the MOT!

These things happen. After the 2 new air bags and rear suspension arms for last year's MOT this is a bit cheaper

All part of the joys of the green oval,

It's a cautionary tale to show just HOW fast and how far south all the systems can go, probably a reminder to check battery in time for winter  Formerly happymadison1978
