Cabin vibrations at idle while in drive

Hi

E320 CDI - 137,000 miles with FSH.

I've just replaced the 2 motor mounts and the transmission mount as one of the motor mounts was leaking fluid so figured I'd do them all while I was there. The car felt so much smoother and quieter for a couple of weeks.

Now I'm getting a load of cabin vibrations at idle - only when the car is in drive, not park or reverse. This goes away once the engine has warmed up.

Could one of the new mounts be bad and have failed or might this suggest a bad injector or whatever?

Thanks

sounds like poorly made mounts to me. Parts warranty!!!!!

And or find out who makes the mounts that the stealership gets and see if you can find them from a wholesaler...

I would try husker and see how much the mercedes motor mounts are, a lot of times their prices are close to aftermarket or not much more

I agree that you probably have installed poorly made parts. I've received good service from AutohausAZ
https://www.autohausaz.com/index.html
Cost $166 for both engine mounts with free shipping

Or Mercedes Parts Center if you want dealer parts at a reasonable cost markdown
