Chronic P24A5 - Exhaust Gas Recirculation (EGR) Cooler Bypass Bank 1 Control Stuck

[hlconwayjr]

This truck has been at the service center for the check engine light (CEL) over a dozen times, first visit to the dealer on June 22, 2016 approximately 6000 miles. The only diagnosis code is P24A5 - Exhaust Gas Recirculation (EGR) Cooler Bypass Bank 1 Control Stuck. During the multiple visits to the servicing dealer attempting to correct this issue first by flashing TSB 18-053-14 REV. B, then replacing the EGR valve, PCM, engine-wiring harness, cleaning the EGR system and replacing several other components along with several CEL light resets, still no success in correcting the problem. The light comes on after sitting overnight cranking engine wait a few seconds, 30-60, for the oil pressure to get to operational pressure. Take off in first gear not using the accelerator pedal, change to second gear again not using the accelerator pedal and within 1200 to 1300 feet driving down a slight downhill grade the light trips. This is very predictable and repeatable. Now over a year later the latest attempt was installing a data logger provided by RAM and Cummins monitoring the operation of the truck. Well this was also to no avail. First, instructions were to operate the truck as I usually do, then after the CEL tripped, the new instructions were to crank the engine, let it idle for 3 – 5 min for the computer to synchronize with the download computer via satellite. None of this has been unsuccessful in correcting the problem. Returned the last time on July 20, 2017 and they removed the data logger and said a software update is forthcoming. My question is are any other RAM owners having this issue, and if so what the corrective action was? If this is a fluke with just this truck, I would also like to get some ideas from this forum in hopes to find and correct the issue.

A 2016 Ram does not come with a 5.9 or am I missing something?

 

[hlconwayjr]

Not seen this one......subbed. Hang in there brother....it sounds like the dealer is at least making an effort.

 

[hlconwayjr]

oh well i suppose i am the only one with this issue. hmmmmmmmmmmmmmmm

Were they able to down load any data from the recorder ? Have they been working with the Star center?

 

[hlconwayjr]

Yes, the servicing dealer was working with RAM and Cummins engineers, I am not sure if they were able to download the data from the logger. I was told that the engineers "have what they needed". I am not exactly sure what that is, I was never able to get a straight answer to this question and others. I was told by the service advisor that a new software update is expected to be released later on this year to correct this issue. It is hard for me to believe a new software update is being developed for all RAM Cummins trucks and I am the only one with this problem. Yes it still has the problem, I have verified the code is the same and reset the light multiple times since the truck was at the dealer.

Have you discussed the lemon law with your dealer?

 

[hlconwayjr]

Yes the lemon law has been discussed with the dealer and FCA warranty and the offer was a slap in my face.

 

[jhenderson]

You spoke directly with FCA?

 

[hlconwayjr]

The warranty department.

 

[jhenderson]

So why haven't you started the process?

 

[Bob4x4]

lemon law requires you to pay for the time and miles that have been used-in many cases this amounts to a trade in deal

 

[jhenderson]

I would assume the time of the first repair attempt comes into play. Being strung along to reduce the truck value is evidence of bad faith.
