  1. B5: Climatronic: how to fix or replace evaporator sensor?

    Volkswagen Passat B5 Discussion
    I have problems with Climatronic HVAC (A/C) system in B5 Passat.

  2. Upstream O2 sensor diagnostic?

    Volkswagen Passat B5 Discussion
    I recently replaced the front pipe (also called an "intermediate" pipe or flex pipe) on my 1.8T exhaust. To do that I had to remove the catalytic converter. While I had it out I thought it would be a good time to recoat the o2 sensors with antiseize since they're the original sensors 15+ years...

  7. EPC light and Crank Position Sensor Change

    Volkswagen Passat B5 Discussion
    Yesterday I was caught by surprise when tried to start the car (1.8T 2002). It took several attempts to crank the engine but then instantly got the EPC light and high idle. Based on what I read in the forum, the culprit should be a bad crank position sensor. Is that a right assumption? Or should...
