Installation instructions for Bailey Motorsports DV30 Diverter Valve For Audi A4 and Passat B5 1.8T
Tools required for this install:
• Medium flat blade screwdriver
• Tin snips (suggested but not required)
Install time:
• Approx. 30 minutes
Installation of the Bailey DV30 requires accessing the engine from below, and is easier done on jack stands or a lift. If installing your valve on jack stands, please make sure they are of high quality and properly placed!
This installation sheet details the install of the a Bailey DV30 on a 98 and later Audi A4 or VW Passat B5 1.8T. 97 and some early 98 A4/B5s have their diverter valves in a slightly different location, higher up in the low pressure boost hose. Install on these vehicles is similar, but requires access from above and below. Removing the passenger headlight helps, too.
The first step to accessing the diverter valve on your A4 is to place the front of the vehicle on jackstands and remove the undertray beneath the engine. Anybody who does their own oil changes will know what to do here. Find the metal slotted fasteners located around the periphery of the tray (there are 3 along the leading edge right behind the lower spoiler, and three along the trailing edge by the transmission). Simply twist counter clockwise to release. Do the same with the 2 plastic fasteners holding the tray in the wheel wells in front of each tire. Slide the tray slightly towards the back of the car and drop down. The diverter valve (DV) is located on the passenger side, in the area between the passenger front tire and the lower spoiler, just to the passenger side of the AC compressor. Download File PDF
