Attention: TDR Forum Junkies I have in front of me a copy of "SERVICE BULLETIN 18-033-07 REV. A", announced on 6/12/'07.
[This bulletin SUPERCEDES the UN-REVISED "TSB 18-033-07", which should be removed from service-dept. files. ]
I can/will not post quotes, other than the immediately-following one, because of what it says:" No part of this publication may be reproduced,(... ..... )in any form, by any means, (... ... . )without written permission of DaimlerChrysler Corporation. "
Therefore I will attempt to paraphrase most of what follows:
The subject has to do with the accumulation of soot, difficulty reprogramming PCM(Power Control Module), and the enhancements of other engine systems.
Very specific instructions are included regarding steps to be taken to correctly accomplish this "flash".
The bulletin is intended for 2007 models of the 2500 and 3500 series Ram trucks, having the 6. 7L diesel, and built on-or-before 6/11/'07.
The bulletin allots. 7 hours labor time, with possibly an additional 1. 2 hours, up to a total of 1. 9 hours(for both), depending on requirements of the particular vehicle. ["Labor operations" which are/may be involved, are 18-129-04-34, and 11-50-02-90. "StarSCAN" must be used to perform the procedure. ]
8(!) symptoms or conditions are addressed, INCLUDING technicians having difficulty/failing to be able to accomplish the flash(s). ( A special, different reprogramming procedure is required. )
The 8 symptoms have up to 6-or-so subdivisions (as in 1A, 1B, 1C,... , etc. )
THIS FLASH DESCRIPTION IS EXTENSIVE!! 8 printed pages!
It requires an intelligent, careful technician who is a GOOD reader. ( Step X, items A thru E, followed by Step Y items A thru I,... etc. , etc. , etc. )
If/when the procedure is completed, the service dept. is instructed to place an "Authorized Modification Label" on the vehicle. The modification "part number" is shown as 55351105 AT on the AML on my truck(which has the 6-speed auto).
This label has been placed above the radiator, about 8 inches to the right of the hood-latch on my truck (YOUR right, as you face the rig).
I have no way of knowing whether the flash was/was-not accomplished correctly on my rig,... but here is one possible indicator; I have driven the truck 750 miles with no EVIC "alerts", and no noticed indications[unusually high temps on the EGT gauge(pre-turbo installation)] of "active regen".
To contrast this with an "un-flashed" ( I believe) rig, delivered to Brad the day before the flash became available; he reports a high-temp indication ( on a similarly-mounted EGT gauge)about once an hour for approximately 1 min per incident. I do not believe 10 such occurrences would have escaped my notice on the 754 miles I have driven. I did not see the gauge read over 1200 deg. (usually much less), at any time, regardless of the varied driving I did (45-75) with occasional attempts to "load" the engine by accelerating uphill, etc. (once or twice, unintentionally, to 80-or-so,... it is very easy and very quick with these trucks when empty!)
The literature describes the "passive regen" as "transparent" to the operator. If any regen was going on during my drive, it was certainly transparent to me.
We need to understand more about this process, as I don't see how "passive regen" is likely when the pre-turbo temp stays below 1100-1200 deg. at normal highway speeds, and temps further-down the exhaust path(at the DPF) should be even lower, by 300 deg +/-.
Please do not expect me to answer the many questions this post will (understandably) raise about the specific contents of this bulletin. .
I would very much want to know more, if I were reading this, and I suggest that you address this issue with your dealer, and BE INSISTENT!
If any service manager gives indications of dis-interest, ignorance, or denial as to the need/availabilty of this "flash" , supply him with the numbers I have given you in this post, and if there is no change in attitude, go elsewhere!
This procedure is "reimbursable" under warranty.
In order to respect confidentiality, I will not reveal/answer questions about my source of this material. Please do not ask.
I post this-much here in the interest of helping other owners get needed service for these trucks, which will no doubt be terrific, once the bug-ironing is finished.
I hope all meet with the cooperative service I have received. There are dealers, ... and then there are dealers.
I bought from Adam Macomber at Dishman Dodge, Spokane, Washington.
Drove +/- 750 miles round trip for the "privilege".
I think that is the correct word!
