Whining sound from Sl65
Guys, my SL65 has developed a pronounced and new whining sound on acceleration. This is twin turbo so some turbo spool whine is to be expected, but the whining sound is much louder than I've ever experienced.
I've had car for about 6 months. Any ideas on why the whine sound has significantly increased?
Car is going to dealer next week for scheduled maintenance
Thx in advance.

I've noticed the whine happens on deceleration also. I'm thinking it might be transmission related. Sound doesn't seem to come from rear (differential). Dealer will diagnose next week I guess.
Anybody else experience similar?

Thx for the ideas guys. I've noticed the whine occurs even when car is at rest and in neutral gear. So, I'm assuming that eliminates transmission & differential. Car goes to dealer on Wed and I'm not driving it.
I'm praying it's not main engine bearing (can you tell I'm a worrier)? :\

have the tranny fluid checked.
also, it could be something under the hood. it could be a pulley bearing, a belt, a water pump, a tandem pump, alternator, a/c compressor... etc...
best to pr1ck your ears and listen carefully

Thanks for the further suggestions guys. It definitely does sound like a gear type whine. I'm not accustomed to having such a 'turn-key' car that dissuades the owner from checking tranny fluid unless they are armed with a special tool. Does an error message post to dash when tranny fluid gets low?

Whining is a transmission issue. Dealer is swapping out entire trans with new one. I'll get details next week when I pick my car up.
CPO + extended warranty is paying off as this will not cost me a penny.
Biggest question is what caused this issue at 30k miles. I'm not rough with my cars. This is previous owned car and you never know how the prior owner may have treated it.
From what I hear, the tranny in the SL65 is supposedly rock solid. I'd expect more issues to surface with the newer 7sp tranny than this tried & true.

Definitely report back when they are done. Hopefully they are not guessing. Not that it matters anyways since you don't have to pay anything. So regardless, a new tranny is a good thing.
The reason i mentioned the pump is because i have heard a similar issue first hand with a whining sound on accel and decel which sounded tranny related. It tuned out to be the tandem pump after alot of troubleshooting.
Good luck.

Update - The dealer replaced the whole transmission and torque converter. I'm pleased that their policy is to replace transmissions rather than tear them apart and try to fix the specific issue. They leave transmission internals to the Mercedes transmission experts. When you think about it, the transmission is probably more complex than the engine internals.
They discovered some metal flashing in the pan but I'd think you might find some metal filings in any trans?
Anyways, my SL is CPO with extended warranty until 2014 so this repair costs me 0$. They also replaced a leaking rear ABC strut, bled the system and aligned my car for 0$.
