Probably. It's the same as any other similar Bosch alternator with a
28mm slip ring uses, and that covers like forty-odd different car
models from BMW, Volvo, VW, etc.
Personally, I went for the "fancy" solution and bought an adjustable
regulator from:

...and bagged up the old working regulator and put it in the parts
box. My batteries seem happier with a little more voltage than the
stock regulator put out.
