24V valve cover gasket DIY? Cam Position Sensor?
« on: May 20, 2016, 04:41:15 am »
I'm quite new to wrenching on cars - any existing DIYs for the T4 (AXK)?

I have the Bentley manual on DVD but I can't find the section where this would be mentioned.

So I have the valve cover gasket, cam position sensor, and the engine filter. Not sure where I should look in the Bentley manual or otherwise for advice.

Did you have a code for the cps? Isn't there 2 (b1-cyl 1, 3, 5 bank2-cyl 2, 4, 6) sensors on the 24v? Sometimes a cam sensor code can be an indication of a chain problem. Test the sensor first and do the valve cover gasket.

I didn't realize there were two sensors for the 24V. I just asked the ECS Tuning live support what I should get.

I have these codes:

Address 01: Engine        Labels: 022-906-032-AXK.lbl
   Part No: 022 906 032 F
   Component:  MOTRONIC ME7.1 G   0004 
   Coding: 00013
   Shop #: WSC 02743 
   VCID: 0E13FF1D4A8BAA4EF3-5124

7 Faults Found:
17748 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28)
            P1340 - 35-00 - Incor. Correlation
17755 - Camshaft Position Sensor 2 (G163) / Engine Speed Sensor (G28)
            P1347 - 35-00 - Incor. Correl.
16839 - EVAP System
            P0455 - 35-00 - Large Leak Detected
16825 - EVAP Emission Control Sys
            P0441 - 35-10 - Incorrect Flow - Intermittent
17704 - Error in Mapped Cooling System (check Temp-Sensor and Thermostat)
            P1296 - 35-10 -  - Intermittent
16730 - Camshaft Position Sensor (G163)
            P0346 - 35-10 - Implausible Signal - Intermittent
17559 - Long Term Fuel Trim Additive Air; Bank 1; Range 1
            P1151 - 35-10 - System too Lean - Intermittent
Readiness: 0000 0000

I found one of the hoses with "fixed" with electrical tape. Given that my dad only gets the car serviced at the local dealership, it was somewhat surprising to find.

Is it running, making chain noise, was other work done recently, when was the last oil change? Hopefully you have a vagcom, and a voltmeter. You have codes for both sensors (g163 and g28) thats not a good sign. If you ignore the evap codes for now the common thread for the other codes would be the 220 ground and the intermittent codes could indicate a bad connection or failing sensor.  The 220 ground is the brown wire right next to the ecu but that would most likely throw knock sensor codes as well. Start by using your volt meter checking the 1 and 3 pins on the cam sensor/s for a voltage in the range of 11 to 12 volts (switch on engine off). I think the g163 and the g40 cam sensors are the same. If the voltage is ok then probe from the sensors to the J220 on the  ecu. To  the right side of the battery. If you look close at the connector you will see indicator numbers on the connector. The number one pin on the g40 and the g163 both go to the number 98 pin on the 220 connector, so using your continuity tester test both #1 pins to 98. Then test the #2 on the g40 to the 87 on the J220, and the #2 on the g163 to the 86 on the J220. If the voltage and continuity test okay then just replace them both. If you have a vag com check you timing and post some engine data so we can look at it. Timing, load, temp, fuel trim, rpm...  With out some data we are just guessing :)

1. The van was running (I say was because I have it semi taken apart)
2. I looked up some VR6 chain noise videos on YouTube but the van doesn't sound like that
3. No other work has been done.
4. Last oil change was about 2500 miles ago earlier this year. Oil is whatever the dealer uses.
5. Luckily I do have a VAG-COM and multimeter.

Once I finish with the dash I'll post the engine data. Thanks for the help!

The big issue is that the oil screen breaks and gets stuck in the cam adjusters. Not actually a chain issue.



It would be VERY odd for both sensors to fail, especially since they rarely fail at all.

Yes it is unlikely to be a cam sensor.

Hey I just noticed your readiness is zeroed out. Is the mil on? Have you cleared the codes to see if they all return? If you clear your codes log the scan first for reference.

hey guys, I'm getting P0343 from time to time, what will you recommend to check?
