OEM Part Number: confirm via VIN — engine mount (aftermarket) Febi 196965 / Lemförder 3949101

Accuracy note: Covers the Fiat 500X (2015-) as listed in the UK aftermarket catalogues. Engine mounts are sold by position (left, right, front, rear, upper, lower), and the right one depends on the engine, the gearbox (manual, automatic or dual-clutch) and the trim. The references below are examples from the UK aftermarket catalogue for the engines checked on this generation, so match your own engine code and gearbox before ordering; the carmaker's own numbers are not quoted in those listings, so check the genuine mount against your VIN if you want a guaranteed match.

Confirmed: A Genuine Technical Bulletin Worth Knowing About — Fiat 500X Engine Mount

This is genuinely worth knowing if you're experiencing unusual vibration: a confirmed technical service bulletin has been issued specifically addressing excess engine mount vibration on the 500X, with documented repairs replacing mounts under this bulletin at relatively low mileage — one specific documented case saw the passenger side mount fail, causing genuine clunking and vibration, at just under 49,000 miles. If your car is showing similar symptoms, it's genuinely worth asking a dealer directly whether this specific bulletin applies to your engine and drivetrain combination.

A genuinely specific, real technical detail worth knowing: the mount contains a plastic component internally that can break down and deteriorate with age and heat cycling, distinct from the more commonly expected rubber perishing — worth knowing this as a genuinely specific failure mode if a mount is condemned, since it explains why a mount can fail even when the visible rubber portions still look reasonably sound.

It's also genuinely worth knowing a useful DIY diagnostic technique for isolating whether the rear mount specifically is responsible for a vibration: disconnecting the rear engine mount and instead supporting the engine on a trolley jack, with a block of wood and a rubber mat placed under the sump for protection, then running the engine to see if the vibration disappears, can help confirm whether this specific mount is the genuine cause before committing to a replacement.

Fiat 500X Engine Mount: What It Does

Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the 500X use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.
