Limp mode caused by vanos bolts?

Hey guys since my car is out of storage, it's been throwing some codes (getting in limp mode)randomnly... Vanos bolts recall is being done in 2 days and I wonder if those are related:

2C70 Boost pressure sensor, electrical: Short circuit to earth
2C58 Boost pressure control, deactivation: Boost pressure build-up blocked
281B Absolute pressure sensor, intake pipe, electrical:Short circuit to earth

Taken from in-dash code reading and http://www.n54tech.com/flash_files/N55_codes.pdf

Also JB4 went crazy a couple of time by not activating at the start of the car and by gauge hijacking not returning to normal use.

So are the two issues related or the JB4 connections may be the trouble?

Thanks

Edit: Forgot to mention that codes only show when I start the car, doesn't mather hot or cold, and just a restart clears the limp mode.
