Time for a new Alternator

[Nognar]

Well it seems to be the warm weather has upset the S8 a little.

Went to drive it today and it had a little trouble! Jumped it OK (Anker Jump Pack highly recommended as it starts a 4.2!) and drove from that point fine over a 20 mile test route.

Started OK after that and seemed to be back to normal. Looking at VAGCOM I am only getting 12.5v when running on the measuring blocks (The 2.8 A8 gets 13.7v as a comparison), confirmed this also with the good old multimeter.

It seems the S8 has lost a couple of vital volts when running.

Battery is good (tested) and is in fact a reasonably new Yuasa Silver, so do not expect that to be the cause. Therefore it looks like a new alternator is needed to me. Now the old one has done nearly 199,000 miles so its best years are behind it and provided good service.

What's the Alternator of choice?

Euro Car Parts have a Lucas (150A Model - 401441231) one for £335 using there daily magic codes or CarParts4Less for £287.

Though Gloucester does have a specialist that reconditions starters and alternators so may try that instead.
