The Red battery light of Joy

[Nognar]

Driving the S8 this evening and having a great drive in a wonderful car.

On the way home the red battery light came on that is on the rev counter. Most odd I thought as the car is going well and its got a new battery in the back.

Stayed on and I was thinking hello is this an Alternator problem....

Driving through Cheltenham and more warning lights came on, dash dimming, battery light on the DIS, gearbox goes into limp and yes the poor old battery was clearly being drained and not charged. Luckily got it just to a friends house and parked it up and I can worry about it tomorrow. So its either going to be an alternator failing (was working fine) or its thrown the belt due to a grumpy tensioner.

I mean I cannot be too hard on the old girl it is 18 years old and done over 200k so the occasional old part is allowed to wear out!
