BMW Engine Mount Failure: Symptoms and Cost

Vibration at idle in Drive, a clunk shifting into gear and an engine that moves a lot when revved point to engine mounts on the E90 and E92. The 335i mounts are fluid-filled and wear sooner. Get a second opinion before paying, and add mounts to an oil pan gasket job because the subframe is down anyway.

The symptoms

The engine mount page lists idle vibration in Drive, a clunk when shifting and heavy engine movement. It covers the E90 and E92 328i and 335i. See Engine Mounts and BMW E90 repair costs.

A second opinion

In the cited thread an independent shop confirmed that mounts a dealer flagged were still fine years later. Ask what test showed the mount was bad.

Do it with the oil pan gasket

The oil pan job removes the mounts, so owners add new mounts while the subframe is down. See Oil Pan Gasket. Rough idle also has other causes; see the BMW Rough Idle and Misfire: Causes and Repair Costs.

Vibration elsewhere

A shake under braking or at highway speed is a different list: the BMW Vibration and Steering Shimmy: Brakes, Mounts and Driveshaft.
