Wolfy, my truck will not accept that TSB, it will not clear the overhead code and check engine light. What now? New cat/dpf? As a side note, the first time it was tried, at the dealer where I bought it, the tech told me that it was not regenerating before the 45 min drive and after it was still not regenerating. He just said to take truck and drive it. It was not showing a cat full service required at that point. Shortly thereafter it was, now it won't clear. The second dealer worked on it all day yesterday with no luck, said to give them until 10:30 this morning and then call. Any suggestions? I'm out of work.
Hi EB,
I feel for your situation, and wish I could offer more help. I am not an expert by any means, just an owner trying to gain some knowledge about these things. Unfortunately the main difficulty seems to be getting access to information.
Here are some thoughts, though:
If the problem is really one of "accepting"the flash, ... and not one of the mechanical parts failing to do-as-directed by the newly-flashed computer, ... then It is not "your truck" that won't accept the re-flash. It is the COMPUTER on your truck. The tires are fine, the injectors are fine, the seats are fine, ... AND the DPF/DOC/Pressure-sensors, etc. , etc. , etc. , ... may all be fine. (If your desktop computer wont start, you don't look at the desk or the rollers on the desk legs, etc. )
A defective computer, like any other defective part can be replaced.
Determining where the problem is(and fixing it) is THE business of a service department. After trying several service departments, NONE OF THEM being able to remedy things under warranty, I believe you will have a serious reason to consider replacement of the unuseable/unservicable vehicle, and the manufacturer/dealer should be obligated to replace it, perhaps under a "Lemon Law".
Remember that I am not a lawyer,... but common sense should play at least SOME part in this . You bought a truck, with the reasonable expectation that it would perform as-advertised, . . and with the further reasonable expectation that if it did not, ... then the manufacturer's/seller's agents would be able to make effective repairs.
If they prove, by non-performance, that they are incapable of restoring your truck to normal, dependable function, it should be their obligation to replace it.
Putting a man out of work is serious business. ( ... and a violation of a contractual implication ... "We will sell you a truck THAT WORKS. ")
I would stress this point to the dealer, and request a "loaner" truck, suitable for your job needs, while they find a way to resolve the difficulties with yours.
It seems likely to me, after having read the TSB myself, that some service tech is glancing at it, ... saying to himself, "Oh yeah, been there, done these things before", and merrily proceeding to NOT DO IT RIGHT, as the very explicit instructions would have told him to do it, if he had read/followed them.
Sadly, there is a careless-or-inept person behind every bush, no matter what their job-description. ("president" for example)
These "modern" hi-tech combinations of mechanisms and electronics are not forgiving of such carelessness.
I suggest being FIRM,... and don't be afraid to become loud,... just see that what you say loudly is justified, reasonable, and accurate (no names, profanity, etc. , ... but let them know you expect and are determined to GET, satisfaction. ) [The Eastern cultures are correct in recognizing the impact of embarrassment,... their social and business codes make it a serious offense to embarrass anyone. This supports the notion that embarrassment is a powerful threat or tool, if its use becomes neccesary. Few things will motivate anyone more strongly than seeking to avoid it. (except, perhaps in our society, money

. ]
If "loud" is not to your taste,... then calmly but in very clear words, at least make them aware that you are ANGRY,... not just inconvenienced.
Back to the symptoms; If the computer "won't clear" a warning light, for example, then there is either a real mechanical problem, or a bad sensor, or a defective electrical connection/electronic function somewhere in the path from the supposed "problem" location to the computer screen.
Dealing with this sort of thing is the reason service departments exist. It is very troubling, to say the least, when they won't/can't, in any case "don't" do their job!
I sincerely wish you a quick solution and acceptable outcome!
