2017 GLE Clunks on Hwy then won't go past 2,000 RPM. Works fine after restart.


Code: P0455 Evaporative Emission System Leak Detected (Large Leak)
Code: P2617 Crank Position Signal Output Circuit / Open
Googling them there codes next.
I would only put OEM Mercedes CKP. I have seen aftermarket ones are hit or miss.

Your engine is trying to save itself from itself. This is a critical thing that you need to get figured out ASAP, as in before you blow up the engine and it ends up on the "I do cars" channel on youtube.
The Best of Mercedes & AMG

I should of mention earlier in the post. Your vehicle is running in limp mode. The RPMs are typically restricted to a low range., often around 2k-3k RPM, and the vehicle may also be locked into a low gear, limiting speed to around 30-50mph, as the car's computer (EDM/ECU) enters a safety mode to protect the engine and transmission.

You need to put the car in a state of known and repeatable condition. You haven't done that yet.
You can buy a 2017 GLE with 150k miles for ~$12k. Buying a comparable newer vehicle with fewer miles will cost at least $12k. So what do you want to do with that information?

4. Replace coolant level sensor - Error went away with new batteries
5. Change the transmission oil - No need per records
6. Change the transfer case oil - Not needed.
7. Check cam position sensor and cam magnet sensor connectors for signs of oil - This last time at the shop I replaced the crank shaft position sensor
8. Clear codes Done

What do insides of the cam position sensor and cam magnet connectors look like?

I will report back.
