Maybe vw sensors are that sensitive ? Also this car has a poor idle in park only and fuel trims look great in park or in gear so maybe a balance issue with poor idle ? This is a timing belt engine with a single coil and wires with only a MAP sensor. The sensor has a jumper harness soldered to it from factory so don’t believe at all it’s connector 6 inches away from sensor. Now I can tap on and new sensor is causing a stall. I do recall tapping on sensor after replacing And it did not stall with new crank sensor. I had replaced crank sensor on last visit with oem part because I could tap on it with extension and would stall. Moserwa: Comments: I was driving my Jetta 4 on a dirty road,in the village,relay 443 937 105 a fell ,I dont know where I must fit it and what purpose does it serve because the car seems to be operating well,any idea please help J: Followup from the Pelican Staff: What is the year and model of vehicleI can see if I have that info. IF it hasn’t been changed since new, replace it now. Since the MK4 1.8T has a vacuum reservoir mounted on top of the valve cover weve also included a simple relocation kit to move it out of the way. This stage 2 kit includes a wrinkle red conversion plate, black 2.0T coil packs, and anodized silver coil pack hold downs.

#Jetta 2.0 coolpack code
Found fuel pressure was 25 psi too high causing rich off idle code which has not returned in many months ( I replaced fuel filter / regulator because it had the turbo motor filter on it and this is non turbo ) and hundreds of miles but still has a no start randomly that I only witmessed recently in a parking lot but by the time I pulled codes ( none ) and proceeded to pull plug wire to check spark it fired up. Answer (1 of 2): Code P0036 refers to heated oxygen sensor(HO2S) 2bank 1heater control circuit malfunctioncauseswiringHO2SECM The HO2S sensor is the one in the exhaust manifold before the cat converter. ECS Tuning offers a 2.0T coil pack conversion for you 1.8T. It had never acted up as far as no start or stall. No check engine light but code is pending and theres still a misfire. Originally it had a check engine light for rich off idle and no start. Depending on which Vr6 engine your vehicle has, you could be looking at coil packs (12v) or 6 individual coils (24v). So I have a vw 2.0 that Stalls or no starts after several trips about once a month.
