Does Softechpro Solutions disable P229E cleanly without breaking other diagnostics?
Yes. Softechpro Solutions v2.0.6 parses the exact manufacturer fault-code and switch tables inside your 100% virgin binary so only P229E / AdBlue / SCR Off + NOx Inducement Off is deactivated while all other engine protections remain active.
