It's just the wet belt slipping imo. Mine did it before and after a new alternator but only after rain or washing the car. It has done exactly the same thing for the last five years so it doesn't me me a jot.

Mine also did this before and after a new alternator was fitted.
I hadn't yet made the connection with rain or water.
I'll try and be more observant.
What I do know is it wasn't the alternator that needed changing :sad:

wasz, mine does it with a new belt or an old one. 100% only happens when the car has been washed or stood in heavy rain, on most occasions I can hear a squeel as the belt grips and starts charging.
It is worse after washing due to the car shampoo I use, I think. It is slippery stuff!
Turbos are more prone to belt slipping when wet than non turbos .. trust me ive been asked to stop this many times before on Turbos .. i dont have an answer there im afraid
Best guess would be a new tensioner but not a cheap solution and not one ive been able to try .
Not so bad I guess as I now have a new 150A alternator which will be good for some years to come but I wish I'd seen this thread before deciding it needed changing.
Live and learn eh :roll:
This is what's currently laying my 996 up. New battery, new alternator, 13.6 at the posts when running but showing sub 12v on the instrument cluster. Disco warning lights and flickering gauges, and stalls on occasion as soon as the brake lights are illuminated, at which point it won't restart despite it having 12v+ at battery.
May not be related to yours. Mine was solved by changing the ignition switch. It started out very much as an intermittent drop in voltage on initial start up so there's similarities but like everything electrical it's a dark art full of guesswork half the time.
