Suspected cause

Since you've got '99 it's probably a good idea to do your fuel filter as well (just behind expansion tank and in front/over of the AOS).

Suspected cause

Replacing the hoses is probably a good idea, but I would say it would depend on the mileage.

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I�m going to tackle my water pump, coolant expansion tank and coolant hoses and so also decided to replace the AOS. I know the AOS has several hoses attached to it. Not sure if these are coolant , oil and vacuum hoses. Just want to replace everything that is attached because I�m sure these parts are also old and brittle. Does anyone know which parts to replace and would replacing these be difficult? Any parts names and or numbers along with any tips would be great. I�m feeling a bit intimidated by the AOS procedure but while I have everything apart want to replace everything that could fail later because I don�t want to do this again for a long time. Car is a 1999 C4 manual.

POST 2Original post

Since you've got '99 it's probably a good idea to do your fuel filter as well (just behind expansion tank and in front/over of the AOS). I hope you're lowering the engine a few inches at least...

POST 3Original post

Replacing the hoses is probably a good idea, but I would say it would depend on the mileage. You will need new intake runner gaskets. The AOS to Bank 2 hose is a PITA to route and replace. Only replace with a Porsche AOS because you never want to go in there again.

The intake gaskets for sure. I assume the Bank 1 hose would be much easier with the engine out or when a new clutch is being put in? So forget the vacuum hose. What about the coolant hoses?

i am beginning to be in complete agreement with you on this.

POST 8Original post

I was going to drop my motor this coming winter to tackle all these jobs at once as well. Looking forward to hearing about your process and any tips/tricks you learn along the way.
