After exactly 1 week my bone stock 07 6.7 showed the check engine light. The odometer showed 2 codes, P2000 and P0516. The dealer tech said his diagnostic system indicated the P2000 was not really a problem (not sure how he could tell) and reset both codes.

One day later (today) I get the CEL again and again 2 codes are shown - the P2000 again and P0128 (cooling system rationality). A different tech, supposedly the best one in the shop looked at the truck and like the first tech, said his system wasn't really showing the P2000 code even though it displayed in the odometer and he has a new fan clutch on order for the P0128 code. The temp gauge reads perfect and the AC works so I'm not sure if there is really anything wrong with the fan.

So my questions are, does anybody know about the P2000 code being ignored by diagnostic system and secondly does it seem reasonable to have so many seemingly unrelated codes?

The truck was built on June 27 and did not receive the AU flash before it was delivered to me. I talked with the sales manager about that and he knows there are software issues but says Dodge won't pay him to update the software before delivery. I requested the AU flash both times when I took it in but they say no since the trouble codes are not related to the issues addressed in the AU update.

I think the technicians are on a wild goose chase responding to the CELs and possibly there is something more fundamentally wrong (wiring harness? computer?) that is creating non-repeatable problems that mimic erroneous data and thereby cause the CELs.

I'm not a tech so I could be totally wrong but this is sure frustrating with a brand new vehicle. Thanks for listening.
