Strange Occurence During Regen Cycle

[JohnnyR]

Whenever my 2012 3500HD Duramax undergoes an emission regeneration cycle, my compass reads 180 degrees different than real direction I am headed. I can't think of a good reason for this, other than perhaps a bad ground somewhere. Has anyone got any guesses or perhaps experienced this weird happening?

Hey JohnnyR,

I just came from another thread http://www.dieselplace.com/forum/63-gm-diesel-engines/365-duramax-fifth-generation-2011-lml/485858-strange-regen-issues.html#post4851706 with similar compass concerns.

I offered to run his VIN to check for compass updates. Private message me your VIN and reference this concern. Thanks,
