@PeterUbers - nope it’s never thrown a code and MB dealer for 2 years (while still under warranty) said it’s normal and they couldn’t recreate the issue.
I’m gonna pull my cam sensors and see if there’s oil on those as I was getting the sputtering start about every third or fourth time before changing the sensors, and it went away for about six months and just started again.
wonder if there is oil on the sensors if that likely is the cause of the sputtering start.

They only fit the magnets which are less likely to be a big leaker (it seems like the sensors on top are more problematic), but I installed them on both of my M157s because the magnets are much more annoying to replace vs the one bolt per sensor on the others. Cheap insurance!

Only MBs - the best or nothing
Are there any initial steps required BEFORE camshaft position sensors harness is disconnected? Like "putting" car's electronics to "sleep" via locking the car (with hood already raised) then observe some wait time period or disconnecting battery's negative cable? Or is it just as simple as an oil change with just the engine off and nothing else is required? TIA

Getting ready to check and replace any sensors and solenoids that need replacing. Cam sensors at FCP Euro ( genuine - $51 ) vs Bosch (OEM - $24) so is it worth paying for life time replacement for twice the amount?
Is Bosch brand OK if I do decide to go that way where I only put 3-4K miles/year?
Thanks

I changed out my 4 cam sensors and 4 pucks after finding oil in 2 cam sensor connectors, after a few thousand miles I inspected and found oil again in the 2 cam sensor connectors that had been leaking previously. I used dealer parts and cleaned thoroughly at the time. I am now wondering if my new sensors are leaking or is the oil that had wicked up the harness previously flowing back down now that the source of new oil has been stopped...I am wondering if any other members have experienced the same thing?

I had this on mine for over 18 months and it's working perfectly. Redneck, but I doubt there's a better fix out there.

Unfortunately found oil in the connector on my15 E63 . This is the cam magnet sensor behind the oil filter housing of course , read through quite a bit . Sorry if I missed anything , was the verdict it can be done filing a little off the back of the filter housing ? Also will order that long 8mm wrench ..
