So last month I had misfire on Cylinder 5. I replaced all plugs and the coil pack for cylinder 5. Now all Cylinders are misfiring 5 is still intermittent.
Also I have a Load Calculation Cross Check and Engine Speed Sensor code. Could the coil packs be causing all this?

Misfire is a symptom of a problem. You're showing "no signal" on the Engine Speed Sensor. I'm pretty sure getting that fixed will fix your misfires as that's kind of an important sensor.

I've ordered the ignition coils for the all the cylinders except for number 5. That one had been replaced last month and it's the only one without a constant misfire code.
I'll clear the codes and try again and see if the other codes come back. My thinking is that if it is misfiring on 5 of the cylinders it will cause all sorts of codes.
My understanding is if the crank position sensor fails the car will be hard to start or will not run. Not sure but the coils are original and when I replaced the plugs last month they were rusty may caused the coils to fail. The last owner did not take care of the car.

I'll let you know how it turns out.

But, cyl 5 *is* misfiring, at least according to that list. You have an engine speed sensor that's dead, unplugged, or the harness was damaged somehow. Why don't you replace that first, clear the codes, and see what happens? It's really really rare that you get a whole engine misfiring and logging codes like that with the issue being *all* the coil packs.

Not sure on that motor. I would replace that before doing the coils. You might need to do the coils anyway, but there is a good chance you'll replace that speed sensor and your misfiring goes away.

I'll replace the sensor as well since it's so cheap. Where is located?

If the speed sensor or crankshaft positioning sensor really has a " no signal" the car won't crank at all according to vw literature. the sensor in coordination with the camshaft sensors are used to detect which cylinder is a TDC at engine start up. If the camshaft sensors fail the speed sensor takes over and the car takes a little longer than usual to crank.

The sensor is located on the drivers side of the engine bottom near the firewall close to the tranny. It is held in place by one small Allen bolt 4.5 mm or 5 mm. The long connection wire runs behind the oil cooler to a bracket connected to the dipstick (left side). Easy to unplug and push off the bracket, hard to put back on bracket unless you have small hands or long fingers.

Drop the front pan and look to the right of the oil cooler against the block. Unscrew the sensor and twist to loosen. I used a Flat head screwdriver to pry out. Pull on the wire after unplugged. Put in the new sensor and feed wire on the backside of oil cooler towards front of car. It should feed right through without hanging up. Top side you should see the plug. Found it easier to plug into connector then slide it back into the bracket on the dipstick. I put a little Vaseline on the bracket to ease slipping it back on the bracket. If you can't get back on bracket not the end of the world, sensor will still work.

Did you change the gap on the spark plugs? Some minor deviations in gap can be compensated for, however if the gap is wrong you will get misfires like crazy. What plugs did you use?

Assuming your car is a V6 3.2L would use the exact plugs that came with the car. They will be pre-gapped, just install. If you get from the dealer they will be about $4 more ($16.85 ea). The vw part number is 101-905-606-A. Plugs are NKG. You can get similar Bosch plugs for about $12, pre-gapped. Do't mess with them. Just install, and take care not to bang end even a little.

I had a short in my R5's engine speed sensor's connector (not the sensor itself)

My sensor sits on the crank.

When it shorts or when unplugged the engine doesn't fire at all.

My 2004 V6 3.2L Died while idling in "Park" last night.

It will crank for a long, long time, sounds good, and has plenty of Voltage, However, It will not "turn over". I scanned VCDS, and got the following codes for address 01.


Address 01: Engine Labels: 022-906-032-BMX.lbl

5 Faults Found:
18104 - Powertrain Data Bus
P1696 - 002 - Implausible Message from Steering Column Controller - Intermittent

P1914 - 008 - Implausible Signal - Intermittent
18033 - Powertrain Data Bus
P1625 - 008 - Implausible Message from TCU - Intermittent
16706 - Engine Speed Sensor (G28 )

17887 - Brake Boost Vacuum System
P1479 - 008 - Mechanical Failure

  • I know what the "Brake Boost Vacuum" System's Mechanical failure is about, and should not effect the engine starting. (Its a small leak in the hose on cold starts only). It's had that for months. This makes sense too: "18322 - Pressure Sensor for Brake Boost (G294) ".
  • "P1479 - 008 - Mechanical Failure" does not sound good, and I'm not sure where to start with this one.
  • The "No Signal" from 16706 - Engine Speed Sensor (G28 ) seems suspicious, but i could just be biased, as I wish this problem to be cheap and easily fixed.
Am I reading this correctly? I'm not sure what the other issues have to do with or what they mean. I am hoping they all stem from one easy-to-fix problem. Other than the Brake Boost Vacuum codes, the rest are all new.
Does anyone else have experience with this or know how to approach this problem?

Does a V6 3.2Liter Gas powered Touareg require TWO "Engine Speed Sensors" (Camshaft position Sensors)?

These are Double Overhead Cams (DOHC), right?

There are two camshafts on the engine referenced. One is for intake the other exhaust. Each camshaft has a position sensor at the back of the block close to the top just below the cyclone oil separator. Due to the very compact V angle (10.6 degrees) the VR6 engine is practically an inline 6. Not really a DOHC as each bank of cylinders does not have both intake and exhaust. There is just one of each.

If your car died while idling and would not restart I would replace the crankshaft sensor. Car will never start if the crankshaft sensor goes out and will die while driving it there is no signal. Car will take a very long time to crank if a camshaft sensor is bad. Would ignore the other codes and replace the crankshaft sensor. The sensor is not expensive. Would not worry about the camshaft sensors as you would get a code if one or both had no signal or intermittent.

Thank you so much!!!!!! I have confidence in starting by replacing the crankshaft position sensor, then going from there.


What does VW call the Crankshaft position sensor? I found it on Autozone's website but not on a Volkswagen parts website. Does it go by another name?

VW calls it a speed sensor. The one you want has a pretty long connector wire as it runs from the sensor behind the oil cooler to a mounting bracket on the left side of the oil dipstick. The sensor is located on the bottom of the block on drivers side close to the transmission. Held in place by one bolt. Kind of a tight location and sometimes is tough to twist out. May have to pry. Goes in easily may take a little work to get the bolt in but once started screws in easily. I would unplug the connector first than underneath pull the wire through and then unbolt the sensor. Feed the new wire towards the front behind the oil cooler. Should feed through without snagging . Get topside and you should be able to see wire and reconnect
