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.

Hi Just picked up my new car today, and after a long journey back home left it ticking over on my drive for a while.
I noticed that i could hear a rattle comming from the centre.
Turns out it's the intermediate shaft rumbling.
The dealer informed me it's normal on turbo models.
Can anyone shed any light or am i facing a HUGE repair bill :sad:
Might be normal for porsche but doesn,t sound normal to the rest of us!Got to admit mine purrs on tickover ,that usual 3.6 groan.Anyway like the man said,don,t worry
Hi There
Recently the Intermediate Drive failed on my 996 C4S Cab - 2004 & 47k.
New engine fitted £13,800 so get it checked out very carefully and make sure you have a warranty that covers you for this...... :sad:
I thought the TT engine bottom end is based on the original 3.6 as is the GT3 and is relatively indestructable, especially compared with the time bomb in my 3.4!!
Even rebuilt engines with new bearings can still rattle - so IMHO it is not a sign of impending failure and can be ingnored especially as it will cost no more to rebuild if it did fail than doing it beforehand only to find it is still noisy.

Thanks all...Put my mind at rest...It is not a bad rattle and i have been told NOT to use the 0W-30 oil. Best to put in a 10W-40..
What oil do you run in your cars and does the 10-40 oil muffle the noise a bit.
Thanks
Hi Mate try 15w 50 next time your oil is due a change does, quieten things down a bit, have sent you a PM with a thread on another forum thats worth a read...as I said previously don't worry.
Sorry to hear, hope you are enjoying the car now you've had it fixed
but different engine on a Turbo, and they have a tendancy to sound a bit rattly on tickover
Not too well up on turbos but I thought the bottom end was based on the old air cooled GT2 (or was it GT1) engine and as such didnt have an intermediate shaft in the way ordinary 996 owners know and love (to hate) Intermediate gear shaft rumble I can understand and is present in lots of cars at idle.
Anyone know for sure...just interested.
