The Dreaded Drivetrain Malfunction Warning

Ran low on gas and before I could fill up the tank received the caution message to drive moderately and call service as soon as possible.

After I filled up with gas the warning went away. However, before I got home it came back on. Before I take the car into the dealer I did my obligatory Google search and discovered it could be one of many issues.

Here's what I did:
- Bypassed the Dinan Elite V2 Piggy-back
- Read error codes P10F3. Cleared both stored and pending
- Drove for about a half hour in bypass mode and no issues
- Reconnected Dinan Piggy-back and drove for another half hour; stopping at the store, brief run on the highway, etc. with no issues.

This is the second day and no faults. Must have been running the car so low on fuel even though I still had over a gallon left some gunk got caught up in the injectors.

If the warning comes back on, then probably a Dealer visit. I'm sure they'll blame it on the Dinan harness even in bypass mode. Ahhhh, the trials and tribulations of tuning your car.
