034Motorsport Density Line Street Density Engine & Transmission Mount Pair for Audi A3 TDI, Volkswagen Golf TDI & Jetta TDI (2005–2016)

The 034Motorsport Density Line Street Density Engine Mount Pair replaces the factory engine mount and transmission mount on 2.0 TDI versions of the Audi A3, Volkswagen Golf, and Volkswagen Jetta with solid, fluid-free performance mounts. Each mount is molded from 60 durometer rubber, about 35% stiffer than stock. Because the mounts are also void-free and solid-filled, the finished mount comes out about 60% stiffer than stock. 034Motorsport redesigned the cast aluminum mount bodies so they can handle the extra stress of spirited driving. The result is less drivetrain slop, crisper shifting, and minimal wheel hop, without a significant increase in cabin noise, vibration, or harshness. Both mounts are made in the United States.

This mount pair carries a 24-month warranty.

034Motorsport developed this pair for the MkV and MkVI Golf and Jetta and the 8P A3 with the 2.0 TDI. Factory mounts use voids and fluid, and the movement they allow is the slop these mounts are built to remove. The engine stays more settled under load, and power reaches the wheels more directly. These are completely re-engineered mounts. They are not inserts that press into worn factory mounts, so the old mounts come out entirely. In any transverse drivetrain, the engine mount carries the engine's weight and resists torque reaction at one end, and the transmission mount does the same job at the gearbox end. 034Motorsport was founded by Javad Shadzi in 2005. It designs, tests, and builds its Audi and Volkswagen parts in-house at its Fremont, California, facility.

Installation & Tuning Notes

The new engine mount has no provisions for the TDI fuel filter or the auxiliary fuel pump. Plan to fabricate or adapt mounting for both components during the swap, because they cannot be bolted back to the mount the way they were on the factory part.

Common Questions

Will stiffer mounts make the cabin noisy?
034Motorsport says the Street Density pair cuts drivetrain slop and wheel hop without any significant increase in noise, vibration, or harshness inside the cabin.

Do I get both mounts in one order?
Yes. The set is sold as a pair, with one engine mount and one transmission mount.

PMB sells 034Motorsport mounts for owners who want a tighter TDI drivetrain without moving to a race-only setup.

Fitment & Compatibility

Check the fitment table below for the exact model years and trims this mount pair fits. The transmission mount will not fit cars with the 6-speed manual, the 6-speed DSG, or 4motion, so confirm your gearbox and drivetrain before ordering. Send us your VIN and PMB will confirm fit for your car.
