Ya, am sorry all German cars have similar issues. To check continuity to ground on the harness side of the camshaft valve which is on the timing chain cover, I would check it via multi-meter to see if there is continuity between one of the pins and any ground, what will the multi-meter show if there is continuity? Ya, I have lots of cars and I always try to challenge my self to fix them and better understand wiring and testing. Appreciate your help.

Okay, let me start one at a time. When checking the camshaft valve adjustment solenoid on the timing chain cover, resistance between the pins if the solenoid itself is 6.7 ohms. With the harness disconnected checking it with a test light there is power in one of the wires with ignition on. If I use the multi-meter and check voltage across the 2 pins of the harness I get 9.75v. Battery voltage is 12v. If I use the multi-meter and touch one aide to the negative battery terminal and the other to one of the pins I get 2.19v if I touch the other pin I get battery voltage.

Also when I touch one if the probes if the multi-meter to the negative battery terminal and the other to one of the pins to check continuity I get value of 1550.

Now for the camshaft sensor on the bottom of the cylinder head. Checked continuity and resistance between it and the camshaft sensor and all were good around.3 or.4.

Okay, so I removed the valve adjuster and it looks good. I believe someone has removed it and the sensor either to look , clean it, or replaced it. Also forgot to mention that the first time uou start it when cold it will make this chain noise attached.

Yes, there is oil.

Reminds me of the phasers on Benz when they went bad, but they still drove excellent.

But sludge would cause it not to have any power? Maybe due to sludge in the valve cover and the sensors not able to read?

So I removed the rubber cover on lower timing chain cover and the tensioner is about reaching its limit. So I put it inside my garage and I would need to do a chain job on it before it's too late, I guess the chain has stretched. I know it needs special tools but I always invest in tools. Doing a job like this and since timing is off, would you start by removing the chain where it is now and then time everything then put in the new chain? Or would you put it in time first then move on? My thing is how will I put a car in time if the chain has already stretched? It would not sign up.

I appreciate it a lot. But how you address it? If it's stretched and cannot be aligned. How would I go about beginning? I ordered the kit for all these tools. Or it doesn't matter right now since its out of timing.

What am asking is, I cannot align it first before removing the chain, because the chain is stretched. So would you leave it like it is, remove the chain, realign and install?
