W124 engine harness replacement - stuck!

[multigrade]

Yes, it's that bio harness problem. I'm almost done removing it prior to sending it to Simon at Sileck for rewiring. (Hope I can remember where everything goes when I get the new one).

But there's one cable that snakes down at back of the engine and goes behind the oil filter.

I can't see where it terminates and couldn't get to it anyway. Does anyone have a suggestion as to how to get it out, please?

Thank you.

Could it be the oil presure sensor or might be a solonoid for the transmition 5th gear or overload protection switch.

Thanks - but Simon says it's the crankshaft sensor. I've also stumbled across someone who said he just gave it a good yank and out it came! Putting the new one back won't be as much fun, I suspect...

The CPS will be held in with a securing screw so dont yank it https://charm.li/Mercedes%20Benz/ click on Mercedes in the index at the top

Although I'm not looking to replace the sensor, just unplug the cable - which will come out with a tug?

So you can see the CPS is held in with a set screw http://www.w124performance.com/service/w124CD1/Program/Engine/LHIS/15-0020.pd -- L5 CPS, going ro N 1/3 EZL

This is what I was talking about. And a quick tug did in fact free the CPS cable: crank sensor cable. Not sure how I'm going to get it back in again...

Well post a picture i recon half of cps is still in there unless it a plug type and not held in with a screw

 

[DREAMER NO2]

Looks like you have the other type that got a plug and socket, and all you hace done is unpluged it

Correct: I'm removing the biodegradable harness (see the OP) for it to be rewired.

So, just to wrap up, the harness was replaced on 23 May and the car is now fully operational...

Excellent news. Out of interest if you don't mind what was the cost of the refurbed harness?

 

[multigrade]

It was around £600.

Plus the cost of my dignity, on my hands and knees on top of the engine, in order to plug in the crankshaft position sensor cable...

I had Sileck do my R129 harness a few years back. Wasn't as expensive as yours as I think it's a smaller harness. Also had the throttle body harness done too.

They did a great job but I rewired the throttle body myself. The worst part was the damage resulting from getting the wires out of the really tight exit from the body.

At £45 to do the throttle body I wasn't going to mess around!
