Anyone know what could be causing this error. I am posting my timing test from VAG COM. I have no idea what the results mean.

17755 - Camshaft Position Sensor 2 (G163) / Engine Speed Sensor (G28)

I have got the same fault code but I will run VAG-COM and post the results tonight.

What are your symptoms?

I am getting some loss of power and I am exploring whether to replace the sensor only, or sensor and tensioner or timing chain which I understand is ENGINE OUT!

Any update on this? I have the same code:

17755 - Camshaft Position Sensor 2 (G163) / Engine Speed Sensor (G28): Incor. Correl.
P1347 - 002 - Lower Limit Exceeded - Intermittent

Hoping it's the cam sensor as everything else is fine, resets and then comes back on after about 2 weeks.

Thanks.

I have found out mine to be chain stretch. You can measure group 93 (I think) on VCDS and see how many degrees out each cam is to one another.

I had my chain and a couple of sprockets replaced 1 year ago but my timing values have slipped back again along with a loss in performance so I suspect it has something to do with the oil pressure as well.

If the car cranks normally and you get camshaft crankshaft codes that keep coming back more than likely the timing chain is elongated. You can replace both camshaft sensors and the crankshaft sensor but might still have the issue. Cheaper than pulling the engine to replace upper chain. You could try replacing the upper tensioner ($75) looks like a bolt maybe 25mm on passenger side below and slightly behind the throttle body on the block. The plunger piston on mine was sticking and not fully extending. also was slightly out of plumb.

If measurements are less than -8.0 KW (-9.0 to -14.0KW). Chain is elongated. Field 3 display group 208 and 209 are within the range of +8.0 deg KW to -8.0 deg KW chain is OK.

VW has a tech bulletin 15 07 January 31, 2007 2010614 related to this issue.

Not certain how long you can drive with an elongated chain, but have done so for over a year. Chain rattle is only prominent in the winter and dissipates once oil temp gets around 100 deg. My CEL is always on and the codes are camshaft and crankshaft correlation. The sensors are fine. Car still performs idles fine. Can't hardly hear it at idle. Is a little more throaty exhaust wise. Am replacing chain in the spring. In the interim I keep clean oil with changes every few months and oil and filter every 6 months. Clean oil helps the hydraulic tensioners.

Just curious..,what does Kw stand for as far as the chain stretch measurement goes?

Not real certain generally stands for kilowatts. May be a reading from the electrical solenoids that operate the camshaft adjusters on the back of the block. The ECM sends a signal to the solenoids that retard or advance the timing. If the chain is stretched the solenoids probably give a different range reading than when chain is normal. Best guess.

Torque output (measured in Kilowatts) will change with cam timing.

 

[G6mdxvct]

Torque output (measured in Kilowatts) will change with cam timing.

Makes sense as kw is a measure of power as opposed to kwh kilowatts hours of electricity. What is the output device that provides the reading in block 208 and 209. Is it coming from the ECM, or camshaft adjusters?

 

[Treg Man]

Just thought it was odd because I thought measuring blocks 208 and 209 were a measure of how many degrees the cam shafts were off.

 

[G6mdxvct]

Just thought it was odd because I thought measuring blocks 208 and 209 were a measure of how many degrees the cam shafts were off.

The camshaft adjusters can increase power and torque. Think maximum adjustment of the intake is 52 deg of crankshaft angle and exhaust 42 deg. If the measurement were degrees why use kw? Think it is a measure of power as can't imagine the angles being off that much and car running right?
