Accuracy note: Covers the Audi A3 (8V 2012-2020) 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.

Audi A3 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 A3 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 Alarming, Honest Real Account Worth Knowing — Audi A3 Engine Mount

If you've recently had a timing belt or chain job done, this is genuinely worth knowing: one documented case saw the bolts securing an engine mount shear off entirely while driving, just 5,000 miles after a cambelt replacement, with the theory being that the mount, which needed to be removed to carry out that job, wasn't properly resecured to the correct torque afterward. It's genuinely worth having the mount bolts specifically checked if a clunk develops within the months following any engine work that would have required removing a mount, since a bolt that shears off entirely can cause a sudden, dramatic loss of drive rather than a gradual worsening.

A genuinely honest, real account worth knowing before paying for a full replacement: one documented case saw a persistent clunk traced not to a worn or failed mount at all, but simply to a mounting bolt that had come loose. Re-tightening the bolt resolved the clunk entirely, at no cost and in about thirty minutes, compared with a dealer quote of several hundred pounds for a full mount replacement. It's genuinely worth checking whether the mount's bolts are simply loose before assuming the mount itself needs replacing.

It's also genuinely worth knowing that these mounts typically contain a silicone fluid that acts as a damper between the two rubber sections — if this fluid leaks out over time, the two halves can move more freely and eventually make contact with each other, and if left unaddressed, the mount can fully separate. Worth having a visibly deteriorating or leaking mount replaced before it reaches this point.
