Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi all I just see the part in red broken. This is the left one. Driver at left. On C4s from 2003 Tiptro, it is possible to change it easily ? Without moving the gearbox or the engine ? If yes, do I need to remove all the oil from the engine ? Thank you

It doesn't look broken to me ...That "overhang" is due to having been updated with 997 Scavenge pumps.... The 997 Scavenge pumps were designed so that on the M97 engines they could not be " installed incorrectly" .....They can still be used on M96 engines but have the overhang and can be installed in the incorrect orientation... \ Check that yours are installed properly , I have seen many cases in the last few years of them being done wrong because so many shops are now working on the engines... on the drivers side the numbers 1-3 should be on the crankshaft side and on the passenger side the numbers 4-6 should be on the crankshaft side...
