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.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi all, Intermittently, on start-up, the Cayman (987.1 S) is making a squealing noise. This happens on cold and warm starts and probably occurs on in 15 starts. Hopefully the attached video captures it clearly enough on here… anyone know what this is and what I should do!?

POST 2 / ORIGINAL POSTEROriginal post

It doesn’t look like the audio works in my video. I’ve subsequently found out it’s the starter motor. The link below (at 40 seconds in) is the exact noise I’m experiencing. So now my question is, bearing in mind the car is 6 weeks old (to me) and is still within the 6 month warranty - what should I be expecting/asking from the specialist I purchased it from? https://youtu.be/c14V824Q2jo

POST 6Original post

I would be happy with a fix. Starters are not very complicated (sorry to misunderstand the question), but it depends a little on what's bust. I wouldn't sweat it and let them decide how to do it

POST 8Original post

I expect it might just need some graphite lubrication. I think it is the bearing spinning after the engine starts and the flywheel spins faster than the starter…vag stuff on the 20v 1.8t seem to get the same.

POST 9Original post

The serpentine belt can squeal horribly when its worn, or the tensioners not working. It's not a big job to change it.

POST 10Original post

I’m a little late to the party here. I got my Boxster S last week and it was making the same noise. There’s two mind sets here, as either way the starter has to come out. Replacing it would give you a nice new starter, but they’re expensive. Or, strip and lube. I chose option 2. Took it out, stripes it down, lubed her up and back in. Cost £0.00
