Diverter Valve Failure - Audi B9 S4

Is your B9 S4, S5 or SQ5 experiencing a ton of compressor surge? It may be your recirculation valve failing. This has been a common issue across VW, Audi and related products over the years. There are always new revisions coming out and today I'm going to replace my diverter valve with a new one. I started getting horrible surging recently and traced it down to the original diverter valve which is an older revision than the most current. My car is right around 23,000 miles at the time of the video.

ECS Tuning Intercooler & Charge Pipes

Heat kills performance. Today we will upgrade my 2018 Audi S4 (B9 3.0L V6 TFSI) with a shiny new Front Mount Intercooler from ECS Tuning. Intercoolers are essentially heat exchangers for compressed air generated by a turbo or supercharger. Our S4s are turbocharged from the factory and make lots of heat. Combined with tunes, hybrid turbo upgrades and full frame builds the amount of heat created can be astounding. The factory FMIC was just too small to deal with these heat levels, especially in hot climates.

Audi S4 Active Exhaust Rattle Fix

Many B9 S4s are experiencing an annoying exhaust rattle related to the active exhaust system. Some S4s, like mine, even throw fault codes including P0477, P0475, and P049F showing there is a problem with the valves. This is often caused by a weak or broken spring inside the exhaust door control unit. Interestingly Dodge Charger and Challenger models have the same Küster brand actuators flaps/valves inside their exhaust too. Facing the same issues a newer spring has been made available by Mopar that eliminates the rattle.
