Is it easy to install a voltage regulator? (Valeo Alternator)

[structure]

I have an 89 325ix with a Valeo alternator that needs a new voltage regulator. I was wondering if it was an easy job to install a voltage regulator in an alternator that's still installed on the car?

Reason I'm asking, the Valeo alternator looks like it has a cover on it that covers the voltage regulator. On the Bosch alternator, the voltage regulator is in plain sight and can easily be removed.

I guess what I'm really asking is, if there is enough room to remove the old voltage regulator and install the new one once the air intake is taken out.

Structure is da man. My lights were flickering and I lost power a few times on the highway (with all my cluster warning lights lit like a x-mas tree). Alternator voltage tested low (12v). Unfortunately, my alternator is a Valeo and the voltage regulator is semi-internal (part #10 in the diagram above) which is harder to replace than the Bosch voltage regulator. Having said that, the VR can be replaced in 30 minutes without removing the alternator.

Here are the steps I followed:

1) Disconnect battery
2) Remove airbox and AFM in one piece (2 nuts)
3) Disconnect two wires on back of alternator (2 nuts)
4) Remove plastic wire housing on back of alternator (2 more nuts)
5) Remove noise filter on the back cover of the alternator (1 bolt)
6) Remove alternator back cover (4 bolts). This is tricky but can be done in place. You may need to unplug the harness that sits next to the alternator. Pivot the cover to get it past the tight area between the alternator and the engine.
7) Unbolt the old voltage regulator (2 bolts) and pull straight out.
8.) Assembly is pretty much the reverse.
9) Reconnect battery, reset clock, enter radio code :alright

BTW, this is the VR I replaced. Pelican had it for $44.25, about the same as a Bosch replacement. As far as I can tell, the alternator and VR were original (165k miles). Not bad, so I just went for the OEM replacement.

Thank you for this.
My car doesn't charge when I'm in heavy traffic (idling), and I have to jump start it.
