Alright, so your 2.0 TDI needs some turbo love?
Here's the heart of the matter: a brand-new turbocharger cartridge, or CHRA (Center Housing Rotating Assembly).

This is the core internal part that does all the work.

It's designed specifically for the 2.0 TDI engines with 135kw, like the CUNA and CUPA codes.

You'll find these engines in a bunch of VAG cars: Audi A3, Q3, VW Golf 7, Golf Alltrack, Passat, Tiguan, Seat Leon, and Skoda Octavia, to name a few.

This isn't just a basic cartridge either; it's got a variable geometry setup and a billet compressor wheel for better response and performance.

It comes with a new O-ring and features an electronic actuator, making it a more complete replacement core.

It's a direct replacement for a heap of part numbers, most notably 04L253010H.

Just a heads-up, this is the 'guts' of the turbo, so you'll be swapping this into your existing housing or using it to rebuild your current turbo.
It's a performance part, silver in color, and it's backed by a solid 2-year warranty.

If your TDI is blowing smoke or lacking power, this might just be the ticket.
