Are these pretty straightforward once charge piping is out of the way? Any special things to know? Luckily the easiest one to get to is leaking a small amount. Figured to do them as needed. Caught this during an oil change.

Where was it leaking? Into the harness or externally?

Just below the part externally

Is there a trick to removing the connector plugs? I pulled back the white tab and it easily pops right back, but the connector head barely moves when firmly pulled. Tried on another solenoid and had the same problem.





Replaced the four CP sensors yesterday no problem, but that connector is not the same as the solenoids.

Thanks

Gotta use a dental pick like instrument - I actually use a dental pick - to sneak under the cuff of the plug to depress a redundant little clip and then it pops off nicely

Rehabguy

Wouldn't depressing in there do the trick?

PeterUbers

it hasn't for me. I can try that again next time I'm around the engine

Rehabguy

Thanks, buddy.

Thanks Peter, that worked, all four connectors popped off with the help of an angled pick tool.

Two of the solenoid connectors had a tiny spec of oil visible and the other two were bone dry. Added the sacrificial harnesses to all four and will keep an eye on them for any sign of leakage.... The four camshaft position sensors I replaced yesterday were drenched in oil. Next job is to check the ECU pins and connectors.

No leak into harness but were leaking under the sensor itself?

how about other ones?

Saw your reply but hadn't got around to checking the harness at the time - have since checked and yes there was oil evident on the ECU plug (the larger of the two) and pins. Removed oil with contact cleaner and compressed air etc.

I just checked one of the solenoid connectors (connected via sacrificial harness) and it was bone dry after 1000 miles since installation.

Still haven't figured out the trick to easily removing the connectors, lifting up that small black tab underneath with an angled pick is not enough to get the plug off, I spent 20 minutes getting the first one off but am clueless what I actually did to get it to pop off. Spent another 20 minutes attempting the second one but no luck, black tab all the way up but still won't budge, will try again another day.

Pull the grey tab out to its first click then use it as the lever pushing down. The connector will pull right off.

PeterUbers

no *****!!!! It was that easy!??? Ima try this right now

I had been using a dental pick

PeterUbers

Worked like a charm!! Once I depressed the gray tab I did have to wiggle it all a bit then popped off
thank you

Will the sacrificial harness be safe to use on 2016 Mercedes GL63 AMG?

yes any m157 engine. I have on mine as well.
