CEL with a DME code 105201 on JB4 (S55)

[BMW_M4_333]

Hello!
Maybe someone can help me
I use JB4 on map 1. From other mods only BMC intake filters. All worked perfect for me. But from 2 weeks ago I start get CEL with a DME code 105201 / Ambient Pressure Sensor (pressure too high). What can be wrong?
After dell all DME failure codes it can come again after 1 or 2 cold starts.
Thank you for help!

P.S. And no so important question. Can JB4 remember valves exhaust position if i use map 0 (all pass thru). My JB4 remember it only when I use Map 1. Or I have to use Map 4 for stoke performance and valves open?

I received the same code a few weeks after I installed my JB4. It did go away after a few drive cycles. It hasn't returned since. I didn't investigate it further since it went away the same day.

Thank you for your answer. I will try to investigate. Maybe I will find out the issue.

Do you have any other mod? Map 1?

My only mod is the JB4 and I was on Map 1 when the CEL was triggered. I'm still on Map 1.

One more question. I continue to try resolved the issue. After get cel it's go away by itself after driving a little with CEL and no cel on dashboard? Or you erase error codes?

Thank you.
