I just had to swap my alternator today on my MK7. Mine was Valeo but I could only find a Bosch locally, I decided to give it a shot and it worked just fine. Just a PSA for anyone in the same situation, they are both the same barring a slightly different orientation of the plug on the back.

Pros: worked just fine, compatible

In place of the Valeo alternator I installed a Bosch VR6 120 amp alternator with a Bosch ABA alternator pulley (its 5 ribs versus 6 ribs of the VR6).

Pros: increased amperage

I just went over 195,000 miles while I've driven it over 26,000 miles this year with the only failures being the original 15 year old Bosch alternator and the spark plugs needing to be replaced.

Pros: motor itself is reliable
Cons: alternator needed replacement
Mileage: 313821 km

Agree with the other guy to have someone else take a look but if it does turn out to need an alternator £553 really is taking the piss. A quick search on PartsInMotion for your car and I see that a replacement alternator can be had for £108 and if you want branded then a Febi one weighs in at £162 and a Bosch one for less than £200

Pros: alternator can be had cheap
Cons: £553 really is taking the piss

I have one with 44k miles sitting in the garage right now with a bad TPS and an oil leak. 

The last drive down the street saw me with a dead alternator and blown alternator fuse. Replacing those two resulted in the above surprises afterwards. 

Even replacing the alternator is a half day knuckle busting job assuming you know what you are doing.

Cons: bad TPS, oil leak

Literally just put a FCP Bosch remanufactured 2 pin alternator in our 530 last week--it doesn't work at all. Communicating with FCP currently to send it back and get a replacement, but I'm not happy about it. I was told that Bosch was the one to go with for best quality, but now I'm skeptical.

Cons: doesn't work at all
