1 / 63.0 TDI Gen 1 EGR Delete & Primary + Secondary Cooler Delete Kit (2009-2012)
Audi Q7 TDI · VW Touareg TDI
A complete EGR delete and coolant-system upgrade package for 2009–2012 3.0 TDI Gen 1 applications. This kit removes and bypasses the CATA Auxiliary EGR Cooler, p/n 059-131-512-Q, 059-131-512-AC, and 059-131-512-AR, while maintaining coolant flow through the heater core so cabin heat continues to function normally. It also replaces failure-prone factory components with purpose-built billet aluminum hardware, new seals, and upgraded coolant connections, providing a cleaner and more durable all-in-one solution.

Overview
The Gen 1 3.0 TDI has a lot going on under the hood. Apparently one EGR cooler wasn't enough, so VW added an auxiliary cooler, more coolant connections, more seals, and a few extra opportunities for something buried underneath the intake to eventually leak.
This kit cleans all of that up.
Designed for the 2009–2012 3.0 TDI Gen 1, this package removes and bypasses the primary and auxiliary EGR cooler while maintaining the coolant routing required for normal heater-core operation. No improvised hose loops, unnecessary adapters, or mystery plumbing required.
This kit also blocks off the EGR from the turbo and from the intake.
The billet coolant bypass is designed around the factory connection points, allowing it to interface with the original coolant pipes much like the OEM cooler did. Internal passages connect the coolant ports without adding external fittings or additional sealing points.
In other words: fewer parts, fewer joints, and fewer things hiding waiting to ruin your weekend.
Kit Features
- Deletes the factory primary & auxiliary EGR cooler
- Maintains proper coolant circulation to the heater core
- Direct-fit connection to the factory coolant pipes
- CNC-machined billet aluminum components
- Black anodized finish for long-term corrosion resistance
- Replacement mounting hardware
- Removes unnecessary factory coolant and EGR components
- Simplifies the engine and makes future servicing easier
- Block off the EGR completely
- Designed specifically for the 2009–2012 3.0 TDI Gen 1
The result is a much cleaner installation with substantially fewer components packed into the engine.
VW gave the Gen 1 TDI a cooler for the cooler. We figured less cooling systems inside the cooling system probably wouldn't hurt.
A Tune will be required to software disable the EGR, or else you will get some codes.
