R52 Falling in love all over again...

Falling in love all over again...
Finally decided it was time to bite the bullet and take care of some nagging issues with my '07 R52. There wasn't anything "wrong" with the car but there were a few things that just weren't right.
Well, I'm so glad I got that done. It wasn't exactly cheap but one trip to the shop made me wonder why I took so long. A new motor mount cleared up some vibration and harshness. New rear brakes really made a difference too and a flushed system improved petal feel. Other tune-up items just brought things back to where they should be.
Bottom line - it was 18 degrees this morning and I still couldn't wait to take the old guy for a spin.
I admit this level of a enthusiasm from a repair visit is kinda odd...but I'm sure some of you understand.

- strong vibration at idle, especially when the car was in gear
- lurching during 1-2 and 2-3 shift under light to mid throttle
Nothing in the back of the car like you described. When coasting, the car was always smooth.

Once the mount was replaced with a real OEM, the ride is silky smooth again.

I can appreciate your new found love. The upper motor mount when failed is quite insidious. The car just ride crap, but very hard to put the finger on the cause. When it happened to me, I immediately thought it was driveline or wheel/tire related. I just happened to spot the brown stains by the mount when I was checking other things under the bonnet. When it failed the hydraulic mount still have a thin layer of rubber as the vibration shock absorber of last resort.

I'll second that. Before I authorized the repair of the mount, my mechanic sent me a picture of the mount with visible dark dripping down the side.

Don't think it is antifreeze but rather hydraulic oil with rubber suspended within it.
Not 18 here today but did have my top down as well as last week on my trip to the Back of the Dragon and the Snake. Not to much better than the top down on a MINI (that has been modded just a little) on some great twisties.

I wanted to cut one open to see what make it tick but the stainless steel housing proved to be too much trouble than I care to undertake. It will require a metal abrasive cutting disc, risking going to the emergency room for the heroic act in the name of automotive discovery.

motor mount
Hydraulic simply means contain liquid. It just happens oil is predominantly used in the applications because of many properties more suitable.
Here is a Mercedes mount cut open and the brave soul said it contain a smelly brown liquid that is water soluble. It would not surprise me the Mini one is very similar in design from the same OEM suppliers.

abc of hydraulic motor mount
I've been reading up on the principles of hydraulic motor mounts. There are many variants of similar design. They mainly consist of two elements - a rubber spring, and a rubber bladder chamber that functions as hydraulic damper. Similar to suspension dampers the fluid is constricted when it passes back and forth between two chambers. Sure enough antifreeze is used.
Here is one excerpt:
Hydromounts from Vibracoustic offer the highest possible driving comfort. They combine the acoustic isolation function of a conventional rubber mount with balanced damping performance. In a hydromount, the main rubber spring has an upper and lower chamber. The chambers are connected by a series of canals and separated by a rubber valve. The mainspring is filled with hydraulic fluid which acts as secondary damping. On excitation or shock input, the rubber valve opens and closes the bypass channel redirecting glycol flow between the two chambers and changing the stiffness of the mount. To optimize the functioning of the grid, complex hole patterns are developed in painstaking test series to meet customers’ requirements.

I could not get mine all off, so I just used a factory paint pen and touched it up. That stuff is hard to get off and makes a mess.
