I'm looking at 'simplfying' the AUM engine in my 2001 A3 such as removing the unnecessary parts. Please add to this list if anything else can be removed and the stages needed to remove it all; - Secondary Air Intake (SAI) - N249 Bypass Whilst doing this, I'm wanting to carry out the following; - Samco Coolant Hose Kit [possibly] - Turbo Intake Pipe - Boost Hoses - Replacement Air-Ducting (AirBox) - Fuel Filter - Hockey-Puck Valve Clean - Readdaptation - Fuel Pressure Regulator (FPR) Clean - Brake Fluid [possible] - Ultrasonic Clean During this is their any advice I would need and anything else that is worth carrying out during this process. I'd like to remove the AirCon system aswell but that will come if necessary. I have quite a fair few parts already collected ready to be fitted. But a list of any replacment seals/clips would be greatly helpful. Cheers!
