1.8T Audi TT, VW Golf/Jetta/New Beetle A.W.E. Tuning DV1 Diverter Valve

Installation Instructions 

For A.W.E. Tuning DV1 Diverter Valve

For 1.8T Audi TT, VW Golf/Jetta/New Beetle

Step 1:

Here’s an overview picture of the transverse 1.8T engine found in the Audi TT, VW Golf/Jetta/New Beetle 1.8T. The 225hp TT engine looks a little different, but the install of the A.W.E. Tuning valve is the same procedure. 

For picture clarity, and ease of install, the decorative engine cover has been removed. Removing the cover is easily done by twisting the “+” shaped fasteners on the cover 90 degrees. They’ll pop up when free, allowing you to grab the cover and lift it up and out of the engine bay. (New Beetle requires removing 2 10mm nuts hidden under trim caps, and then sliding forward and out) We’ve also removed the PCV damper in the following pictures for clarity. You won’t need to remove this item to install the valve.

Step 2:

On some New Beetles, the stock diverter valve is held in the boost tubes by squeeze clamps. Squeeze the clamp tabs together with a pair of pliers to release the tension on these clamps, while at the same time sliding them down the hose, away from the valve.

On the TT, Golf, Jetta and some New Beetles, the stock diverter valve is held in the boost hoses by one “crimp” clamp and one reusable screw clamp (pictured). Some vehicles actually have crimp clamps at both locations.Removing the crimp clamp is probably the toughest part of the valve install! You can either try to pop this clamp apart where it overlaps with a thin flat head screwdriver, or you can simply cut it with a nice pair of tin snips. Have patience! Download File PDF
