  1. DIY: Touareg 2.5 TDI R5 valve cover PCV valve repair / diaphragm replacement

    General Maintenance & Repair
    This tutorial is marginally related to my other tutorial just posted about valve cover gasket replacement. It makes sense to carry out this one (or at least check the valve) if you're doing the former, but can also be done separately. What is a PCV valve? The valve cover of the BPD/BPE engines...
  2. DYI EGR cooler bypass valve actuator repair

    General Maintenance & Repair
    This is just another tutorial for a repair I’ve recently done on my car, to save others time with the research on how to do this. This repair is related to my other topic about the tricky vacuum actuator leak that causes the engine to run roughly right after start and whenever launching from...
  3. 04 / 05 Valve Bodies bad all along ???

    Gas/Electric/Hybrid/Powertrain | V6, V8, W12, FSI
    I was continuing my never-ending search for closure on why so many 04 and 05 Touaregs and Cayennes are valve body nightmares.

  7. Engine / Valve Train ? Other ?

    General Maintenance & Repair
    2004 V6 70,000 mi. Tonight I drove 30 + miles for shopping. Vehicle was warmed for 10 - 15 min before highway speeds. After 30 mi arrived where I was going and it sounded like I just traded for a V10 TDI. Guessed it was starved for oil but at max. Definately sounds like top end noise. Added some...
