I have 2021 Wrangler Unlimited Rubicon with 3.0 eco-diesel. Stock, no after market toys added yet. I went through a stream that was deeper than I thought and water got into the engine compartment, probably pretty high up. Made it thru the stream then the diesel just backed off to idle. Couldn't move forward or in reverse, couldn't advance throttle even in neutral. Figured some sensor got wet. Buddy started towing back to civilization. After about an hour, I could increase idle to about 1500 in neutral, but not in forward or reverse. About two hours later it ran normal with a few icons lite up on the dash board. Figured one or more sensors finally dried out. Error code from dealer said "exhaust gas recirculator". So, what sensor in the eco-diesel would stop the vehicle from moving when it got wet? Why should you not be able to go forward or reverse, even a low speed? Can this sensor be sealed so water does not stop the vehicle from being operated? Not being able to take a jeep through water seems a little limiting to me.
