Could I put a 120Amp voltage regulator on a 90 A alternator

[goranero]

I needed to replace my old voltage regulator ( ref: F00 M 145 225) and I couldn't find the same anywhere after a long research .

Finally, on the website Auto Parts Warehouse | Car Parts, Truck Parts & Auto Body Parts Online - Free Shipping on most Auto Accessories & Performance Parts – AutoPartsWarehouse I find a voltage regulator for which they say that that model (Manufacturer number: W0133-1613555) fits perfectly for my New Beetle.

But my alternator is a 14 V 90A model (028 903 028 D) and the voltage regulator that they propose and on live chat confirm me is a 120Amp model.

How they could say that is secure to put a 120Amp voltage regulator on a 90amp alternator.

Any advice will be appreciated.

Does somebody had any experience with similar issues ?

Thanks.

It is quite possible that the base altenator is capable of producing 120Amp but is regulated down to 90 on your model. I'm not sure how you would independently confirm that though....

go to vw to confirm you question, then you will know what part to buy

i know on the old style bosch alternators, that the voltage regulator didn't account for the amperage, but you COULD place a 110amp regulator in a 90amp body with no issue. not sure on the newer valeo units.

just get one off a 1.8t from the junkyard, they're 120amp.
