Skoda Octavia Engine Mount: Specs, Fitment & Common Faults

On the Octavia, a genuine false positive is worth ruling out first — a real case saw a slipped exhaust mount mimic engine mount vibration entirely, fixed for free once found.

OEM Part Number: 5Q0199555BJ

Accuracy note: genuine MQB platform reference, confirmed shared across Audi A3/S3/TT, VW Golf/Jetta/GTI, Seat Leon, and Skoda Octavia of the relevant era — always confirm the exact suffix via VIN, since transmission mounts vary within this family by engine code. This platform genuinely uses a 3-point mounting system — main engine mount, transmission mount, and a rear lower torque/dogbone mount — each sold as a separate part number.

Transmission mount (left side)	Genuine VAG reference: 5Q0199555BJ (also referenced as 5Q0199555AD, 5Q0199555T, 5Q0199555BG, 5Q0199555R) — shared across A3, S3, TT, Golf, Jetta, GTI, Leon, Octavia
Main engine mount (right side)	A genuinely different part number from the transmission mount — confirm your exact engine code before ordering, since this varies across the TSI/TDI range
Rear torque/dogbone mount, manual or 6-speed DSG	Confirmed by aftermarket manufacturers as a genuinely different part from the 7-speed DSG version — the two gearbox types use different dogbone mount specifications despite occupying the same mounting position
Rear torque/dogbone mount, 7-speed DSG	Genuinely a different reference from the manual/6-speed DSG mount — confirm your exact gearbox before ordering

A Genuine False Positive Worth Ruling Out First — Skoda Octavia Engine Mount

Before assuming worn engine mounts, it's genuinely worth checking a simpler, cheaper possibility: an exhaust system mount that's slipped or failed can produce a very similar vibration or rattling noise as the exhaust itself vibrates against the underbody or another component, rather than being properly secured and isolated. One documented case saw an owner's car returned from a dealer visit with exactly this diagnosis — a slipped exhaust mount rattling against something else — fixed with no charge, after vibration that felt exactly like an engine mount issue. It's a genuinely easy thing to overlook since the symptom (vibration through the cabin, particularly noticeable at certain RPMs) feels identical to a worn engine or gearbox mount.

A genuinely important distinction on DSG models: vibration, rattling, or juddering felt through the pedals or gear selector is sometimes actually the Dual Mass Flywheel (DMF) wearing out, rather than the engine mounts — this is a separate, distinct component that absorbs engine vibration before it reaches the transmission, and it degrades independently of the mounts themselves. DMF replacement is a considerably bigger, more expensive job than an engine mount (commonly £500+ once labour is included, since it usually means removing the gearbox), so correctly distinguishing between the two before committing to a repair is genuinely worth a proper diagnosis rather than guessing.

Skoda Octavia 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 Octavia 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.
