Genuine downpipe to turbo clamp

Genuine Downpipe to Turbo Clamp – 5Q0253725G

This is the genuine factory clamp that secures the downpipe to the turbocharger outlet on a wide range of VW Group vehicles. While it may look like a small part, it plays a critical role in keeping your exhaust system sealed, secure, and performing as it should.

If you are fitting an aftermarket downpipe, replacing a worn or seized original, or carrying out turbo work, this clamp is one of those items you simply do not want to reuse. A fresh, factory-spec clamp ensures a proper seal between the turbo and downpipe, preventing exhaust leaks that can affect performance, sound, and emissions readings.

Why replace the clamp?

Downpipe clamps are exposed to extreme heat cycles every time the engine runs. Over time, the metal fatigues, the threads can seize, and the clamping force weakens. Once removed, an old clamp rarely tightens back to its original specification.

• Maintains a leak-free seal between the turbo and downpipe
• Prevents loss of boost pressure and exhaust gas escape before the catalytic converter
• Avoids the ticking or hissing sounds typical of a failing clamp
• Ensures correct fit and torque retention under heat

Fitment

This genuine VW Group clamp (part number 5Q0253725G) is used across many popular 2.0 TSI and TFSI applications, including various Volkswagen, Audi, SEAT, and Skoda models built on the MQB platform. As fitment varies by engine code and production year, please use the vehicle lookup on the Racingline Shop or check the Vehicle Fitment tab to confirm compatibility with your car before ordering.

Installation note

This clamp is a single-use item. Once tightened to the manufacturer’s torque specification, it should not be reused if removed. Always fit a new clamp when separating the downpipe from the turbocharger to guarantee a reliable seal and avoid future leaks.

As an authorised retailer, we supply only genuine VW Group parts, so you can be confident this clamp meets full factory specification and quality.

Applications

Please note, customers are wholly responsible for checking fitment for their vehicle.
