Personally, it's your car, do what you want, but I've personally screwed up before and didn't listen to the advice of people on the forums and installed an inferior part only to have it fail with a short period of time.

Just to update everybody - I raised a stink and the shop installed a Porsche AOS.

It's your car - i'd run far away from a shop that doesn't listen to what the owner wants (within reason of course) but in this instance they should have done what you asked without making you kick up a stink IMO.

I'm hoping to get some reports of actual use from folks here.

Why are you so reluctant to use a Genuine Porsche AOS?
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Has anybody used a Vaico AOS? Comments on quality?
Please don't tell me to get genuine Porsche, as that is not an option at this point. I just want to know if these are decent units or not.
Thanks.
You might do some Google or duck duck go searching.
BMW/VW guys have issues.
Personally I think the AOS is not something I'd want to tackle much less more than once for a cheap replacement part. I didn't see where they are a OEM supplier to Porsche, though I might be wrong
I have been googling like mad. I'm hoping to get some reports of actual use from folks here.
It appears they are not OEM, although that information is hard to come by.
Considering what a pain in the behind it is to change one of these things I'd definitely second using a Porsche genuine part for this one. Plenty of places on the car where aftermarket are reasonable alternatives but my two shiny pennies would say not this one, friend.
Hope you're enjoying your new car, man!
OP specifically said that for whatever reason he is not getting an genuine unit (cost / availability / whatever), and is simply looking for experiences with the Vaico unit.
This thread: everybody urging for him to go get a genuine unit anyway...
I'd say he either has already bought it, or Indy has already installed it.
either way I'd discuss it with whomever bought it and rethink it.
Not that I'm a huge fan of P parts and their cost, but usually buy OEM Parts or P parts if reasonable.
Nope - it's a fact! I had a Vaico unit fail, so in my experience they fail 100% of the time - by extension they suck, because they fail 100% of the time...
Misleading? Maybe, but that's what you get when you come to a place like this and ask a question like the OP...
Well that's what he asked for.
not that I care but OP might want to know how long did it last ?
< 30 min.
> 1 day
>1 month
> 1 year
Just so he has an idea on longevity
PS I liked the Matter of Fact opinion
I understand what you're going through. You're doing a lot of work on the car and it all adds up to more than what you were expecting; therefore, you look for ways to save money. In this case, by going with an aftermarket version of the genuine OEM part. I've personally had my AOS changed out recently and the shop refused to install a non-factory AOS because of problems that fall back on the shop when they fail quickly. There are quite a few parts on the Porsche 996 where the only quality replacement option is a genuine factory OEM part (e.g. expansion tank). I would say the AOS is definitely one of them. Personally, it's your car, do what you want, but I've personally screwed up before and didn't listen to the advice of people on the forums and installed an inferior part only to have it fail with a short period of time. Just ask 808Bill what a failing AOS can do to the car. It's not something to cut corners on. Just my 2 cents.
Peace!
Just to update everybody - I raised a stink and the shop installed a Porsche AOS.
The tech said he usually installs Vaico. He even sent me a picture of the original AOS next to the Vaico, and they looked identical: same stampings and manufacturing numbers. Of course, that does not mean it isn't just a Chinese copycat with different internals.
I tried to find out who the OEM was and couldn't. So, the question remains for others - if you want an OEM AOS but don't want to pay for the word "porsche" on the box, what would you buy?
I believe the consensus here is that the Porsche tax is worth it in the case of the AOS, primarily because the labor far exceeds the cost of the part and you want to avoid repeating the procedure when possible.
It's your car - i'd run far away from a shop that doesn't listen to what the owner wants (within reason of course) but in this instance they should have done what you asked without making you kick up a stink IMO.
