Rattling at D

[Varero]

Recently I found the car sort of like rattling at D but when the gear at N is very quiet. Previously even at D u don't feel the rattling or trembling. Is it normal for Merc after some time? Or what could be the problem?

[thaiedwin]

Your mileage?  Might be low on ATF. Just my guess.

[Bullterrier]

Maybe Engine Mounting

[Varero]

Mileage only 16k. Wats ATF? Pardon my ignorance...

[Odessus]

Automatic Transmission Fluid.

[thaiedwin]

send it back to workshop to get it check. You car seems to have too many issue which is not norm for a 16k car.

My ride had the same problem during my second year.  Car vibrated even at N and P and rattle sound from the engine bay.  RPM looks normal though..

 

Send back to CnC to check but couldn't find the problem. And after 2 days of trial and error, they finally found out that my supercharger having problem.

 

Order a new supercharger from Germany and waited for 2 -3 weeks and finally get it replaced.

 

Now all problem solved!

 

Better send it back to the workshop to get a thorough check before your warranty over.

[Varero]

Workshop say the sound could be due to the part that cause the leakage of coolant...

[Varero]

Got the coolant pump change n no more leakage. Change the gear box mounting but still rattling at D. Sigh...

Could it be the supercharger as what Bro Jon say?

[Anle]

Your car should be running on turbo charger, not super charger

[Varero]

Yes my car has turbo so its called turbo charger. So it could be the turbo charger faulty that is causing the rattling or trembling?

[Anle]

Not sure bro.. Our car have the same engine.. Mine is the E250 coupe..bought in Oct 2013, now 16k mileage too.. Have not experience the vibration so far

[Varero]

Mine is July 2014 with facelift n now 19k mileage.Less than a year and many these minor problems...

[Arshavin]

Mine rattling at low rpm. Next week going into c&c for checkup.

Hope problem will be solved soon

[sayaret]

Mine having much much more vibrations.... 55k mileage liao....suspect engine mounting.... sending in for check next week..... expecting to change few stuff like engine mountings n gear box mountings... wonder if its under warranty or classified as wear n tear.

[Varero]

Bro Arshavin & Sayaret, once your problem rectify, pls kindly update to advise what's the cause. Ty

[Arshavin]

Just send me car this morning.

Same old story by See&See

First time hear this problem. Not ATF problem. Not engine mount issue. Not gearbox mount cause too.

Need to park car overnight at their workshop and they will call me back

Haha.

[Varero]

PI change my gear box mounting n still same problem. Next week send in to check again. Dont think they know the problem.

Would like to know if see&see has solve this problem.

[Arshavin]

Collected the car

They just change the idle pulley. The SA told me they change the water pump too but it was not stated inside the paper.

Engine vibration is within normal range.

Just hope is not something serious as warranty period coming to an end soon

[Varero]

The critical thing is does it still rattle afterchanging.

[Etsk22]

Bros, what are your rides? My FL w204 2013 have the same problem too. Left car overnight. CnC check n told Me probably gear box mounting. Not covered under warranty n told me est $180. WenT ahead with the Repair. However, problem still exist. In the end, they told me it's normal as the engine is vibrating n slightly brushing against the bonnet. Ask me to monitor. As it was near CNY period,. I just let it go since I have time for warranty.

[Arshavin]

Mine is FL c204 1.6L.

This is the second time for this problem. The first time See&See change the pulley too. Then the noise return back.

The noise only occur when I start car during the morning or end of the day. And the squeak noise is very loud during the low RPM. Once the RPM is stable the noise go away or the engine noise cover this squeak noise

Mine also approaching the end of 3 years warranty. Maybe we just belong to the small percentage that have this problem

See&See checked the engine and said no problem with engine.

[Arshavin]

Now See&See very strict with the mod that we did on our ride. They took photos of my rides and advise me that the system related to the mod I made may void the warrenty.

Lucky my ride only have this squeaky noise problem. The memory seat problem was resolved after they change both the seat ecu

and I plan to do my 60k servicing outside See&See

[sayaret]

Mine is 2012 W204 (C180)

Will ask C & C to check.... if it is engine mounting and gear bix mounting issue and they dont cover then i go elsewhere to do

[Etsk22]

Hmm. Seems to be a common problem for FL c180. Actually quite disappointed with the level of service provided by CnC. They can't seem to find the fault nn rectify the problem. It's more like trial n error.

Surprisingly,My other close to 10yr Honda doesn't rattle like my less than 2yr Merc. :-(
