Arnott MR-3856 Suspension Strut - Front

Arnott MR-3856 Front Magnetic Strut

The Arnott MR-3856 is a front magnetic suspension strut for Audi TT and Audi TTS applications with electronic damping control. It uses a monotube damper filled with magnetorheological fluid to respond to the vehicle’s control system and maintain the adaptive ride behavior expected from the original equipment setup.

Compatible With 2009-2015 Audi TTS Quattro, front and 2011-2014 Audi TT RS Quattro, front with electronic suspension. The Arnott Magnetic Strut line is built for OE-style magnetic ride applications and is engineered to connect to the vehicle ECU without modification.

Key Features

• Front magnetic strut for Audi TT and TTS platforms
• Universal left or right side fitment for the front position
• Monotube construction for consistent damping response
• Magnetorheological fluid changes viscosity through electromagnetic control
• Adjustable damping function through the vehicle’s electronic system
• New replacement part with standard-grade construction
• Upper stud mount and lower loop/eyelet mount
• Spring seat included; springs, boot, and mounting hardware not included

Product Details

Arnott MR-3856 is part of the Magnetic Strut product line, which focuses on electronically controlled suspension replacement for vehicles equipped with magnetic ride systems. This front strut is engineered for the 2008-2015 Audi TT and the 2011 TTS (8J) platform, with confirmed fitment for 2009-2015 Audi TTS Quattro, front, and 2011-2014 Audi TT RS Quattro, front with electronic suspension. The design uses internal electromagnetic coils to alter damping characteristics in real time, helping preserve the factory-style adaptive ride behavior on Audi TT and Audi TTS models.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues Addressed

• Front suspension noise or harsh ride from a worn magnetic strut
• Loss of adaptive damping response in the front suspension
• Uneven front-end control during braking, cornering, or road transitions
• Electronic suspension fault conditions tied to a failing OE-style strut
• Ride quality degradation on Audi TT and Audi TTS magnetic suspension systems

Installation Notes

Install on the front left or front right side as required by the vehicle. This strut connects to the ECU without modification, but the vehicle should be inspected for related suspension wear before installation. Because mounting hardware is not included, reuse or source the correct fasteners as needed. A professional alignment is recommended after front suspension service.

Quality Assurance

Arnott supplies this new magnetic strut as an OE-style replacement for electronically controlled Audi suspension systems. The MR-3856 is built with monotube construction and magnetic damping control to match the function expected from the factory magnetic ride setup.
