I searched and didn't see a thread on this yet so hopefully someone is savvy about the L494 diesel model. I'm receiving the following codes:
P2BAE00 - NOx exceedance
P2BAE02 - NOx exceedance
P2BAF-00 - NOx driver inducement active

So far I've taken these steps:
1. Replaced the DEF injector
2. Physically inspected/cleaned the exhaust port for the injector (no crystal buildup)
3. Checked the DEF tank, within 1.6L of full
4. Ran a dosing test successfully. Spray pattern is correct
5. Forced a DPF regen

Nothing is eliminating the codes and I'm down to 113 miles before no-start. The nearest LR dealer has no openings for a couple weeks and my other ride is a BMW 645 6 speed. With performance tires. In the upper Midwest. You guys can do that math. I'm getting a bit desperate. Mechanically I'm capable of performing whatever repair needs to be done, but I must be missing something. Anyone got tips where to turn next?

TIA
