Morning trix5. So far the cel has not returned. Truck is driving fine from what I can tell though I have not monitored any smoothness data. I-drive shut down randomly yesterday, has done this once or twice before, which supports the failing battery theory I think. E70 I-drive would do that too when it needed a battery. Going to pick one up today hopefully. Install after it stops raining (don't want to take the garage queen e53 out

) sometime in the next few days.
Will keep everyone updated.
