Febi Engine Mounts e320 Input
Hey guys!!
A few days ago I replaced my engine mounts on my w211 e320cdi with 185k second set of them BTW! originals were replaced at 123k with lemforder brand mounts which lasted about 60k.
Upon replacing the lemforder ones with febi/bilstein mounts I have vibration in the car still does not matter if the car is in N or D however the vibration is more noticeable when in D.
My question to the forum members is, have you guys had any issues with using FEBI engine mounts ? I think its strange that they are this bad out of the box I have over 1400 miles on them and they are terrible compared to OEM/LEMS.
any input greatly appreciated. Thanks & happy labor day weekend everyone!

I did exactly what you did - same result. Ended up swapping them out to Lemforder. No more vibration. In my case - it was when I did the balance shaft. Made me panic thinking I mis-timed the balance shaft - since I didn't think the mounts would be that bad. Luckily I had pictures of every step that I could refer to - confirmed balance shaft was done correctly. And then swapped the mounts.

Good to know ! I will tackle the issue here this coming week ! how long have the LEMS lasted you? one of the shops told me that to get 60k out of them was pretty good, and the parts adviser where i get them from said that they failed early. So I am a bit confused. I am most certainly disappointed with the quality of FEBI mounts!

I am not sure but are engine mounts different for diesel and gasoline engines. My understanding is that it should be since deisel engines are more heavier and vibrate more as compared to gasoline engines in w211?
Could it be that the Febi/bilstein engine mounts are for w211 chassis but made for gasoline engine, I am just thinking out loud here but please confirm if this is the case.

they may be different for gasoline and diesel, the part numbers that I have are 2112403017 & FB-2112400417, those were ordered from autohausAZ btw they have great customers service and good warranty on parts in my opinion.

Hmm...my W211 has 145K on it (it's a CDI). That means that at some point it will need motor mounts, too; right now, they seem to still be in fine shape.
From what I'm reading of your posts, the Genuine-MB mounts last well in excess of 100,000 miles. Even the Lemfoerder ones only last about 60K. I'm wondering, therefore, if it may actually be worth it to go Genuine-MB for this particular part.

in my case the OEM lasted to 123k thats when I installed LEMS those lasted me 60k, today I replaced the febi (TOTAL JUNK) DO NOT BUY THEM IMO, ones with lems again and so far its super quiet and how it should be. I hope that it lasts for at least another 60k plus which I'm okay with for the price and the job being easy to do, took me about 45 min to hr with breaks 110 degrees out today.

I agree from all the shops and mechanics that I spoke with they all say 60k is the max one gets from the mounts, however my OEM MB mounts did last me till about 123k, and cowboyt is still on his OEM at 145k, which makes me think that OEM may last double of what LEMS can.

If I had to guess, I would bet they failed well before that point. They may have taken that long to completely lose all of the hydraulic fluid maybe? IDK, but that would be the longest I've ever heard of on a set of OEM mounts that were still truly good. 60K is a pretty universal number it seems. Ill be surprised if mine last that long being 4matic and that I drive the car very "spirited"

It’s very possible, however the symptoms of them failing are quite significant lots of vibrations in the cabin in my case I felt almost every gear shift vibration changed when I moved the gear selector from drive to park and to reverse. When driving I would feel vibration that changed with rpm of engine and very annoying drone sound that filled the cab when idle. It sounds like you have deep base stuck on one note. When my oem failed the first time they were ripped apart my engine was loose the cabin was like a tank everything was vibrating and it was very bad. I thought my car was done that’s how bad they were. Second time around I was asking on forums and the guys were right engine mounts fixed all of my vibration issues for now. I’ll update in a few weeks to let you guys know how the lems are holding up.

yea could have been designed slightly better but the job is easy enough, mounts are warrantied for 3 years i think so im sure i will be changing them out again within that time.
