Had the same in reverse. Bosch factory, Valeo worked fine though.
Remember the old Bosch and Valeo alternators where the brushes were built into the regulator, which cost $15 and came off the back with two screws? Pepperidge Farm remembers.
Bought a used Valeo alternator, and sure enough, the charging problems went away, and it starts charging as soon as I start the car.
Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.
+1 for Valeo. This job wasn\u2019t fun.
I had Valeo in my other car, very common for Bosche to overcharge.
Alternator stopped charging while driving and it slung grease all over the engine bay and hood.
4 aftermarket alternators in a Volkswagen Vanagon… after the last shit the bed i insisted on a factory one. That solved the charging system issue.
When I finally bought another car and started preparing the Bora for sale, the alternator failed. The only real issue it ever gave me.
Mesmo um Valeo novo está caríssimo, pede mais orçamentos.
