Accuracy note: Covers the Mercedes-Benz GLA (X156 2014-2020) 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.

Mercedes-Benz GLA 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 GLA 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.

A Genuinely Useful, Technical Distinction Worth Knowing — Mercedes-Benz GLA Engine Mount

If you're trying to work out whether a vibration is genuinely coming from an engine mount or a transmission mount, this is genuinely worth knowing: a failing engine mount typically causes vibration felt mainly through the steering wheel, especially at idle. A failing transmission mount usually causes vibration felt more through the seat, floor, or centre console instead, most noticeable when the car is stopped but still in gear.

A genuinely useful diagnostic technique worth trying: with the bonnet open, having someone gently blip the throttle while you watch the engine is a simple way to visually confirm a badly worn mount, since the engine will visibly lift or rock if it's genuinely failing.

It's also genuinely worth knowing that a clunk when shifting into Drive or Reverse points more strongly toward the transmission mount specifically, rather than the engine mounts.
