exhaust filter

I am new, just looking for insight or advice. I apologize if I post to the wrong place etc.

I had to take my truck in for the 4th time because of the exhaust filter 100% full and will not empty
exact same all four times...check engine light, flashing electronic throttle control light, "exhaust filter 100% full service required" message on screen

dealer is telling me:
the check engine light came on because the oil life is at 0%
when the check engine light is on the exhaust filter will not regenerate
I now have to pay for the exhaust filter cleaning

I would like to know if the oil life monitor will trigger the check engine light? I use Amsoil signature series (25,000 or 1 year) and have it tested because the monitor is always wanting me to change the oil thousands of miles too early.

Am I just going to have to bend over and take another one in my rear to get my truck back?

I hate this truck; correction; I hate this exhaust filter. I do to much stop and go city driving for it. Sure would have been nice if they sales person had told me diesel was a bad idea and would be a very expensive pain in my backside.


Thank you

Easy enough way to find out, reset the oil life monitor. Really want to go 25,000 miles then reset it, if what the dealer is telling you is correct problem solved.

Personally I wouldn't go that far, unless you are GDE tuned as it turns off the EGR, with in town driving I'm thinking you are getting a lot of sot into that engine.

I have tried resetting the oil life monitor and it will not reset. How do I reset it without changing the oil? Do you think if I can reset the oil life the check engine light will go off and allow the truck to do a regeneration / clean the exhaust filter?


I do not want to drive it 25,000 miles before an oil change I just know the oil that is in there is perfectly fine at 7,000 miles. Up until now I have been changing it about every 6K and Amsoil is telling me I am wasting my money changing it because the samples I send them are still very good oil. I am not a mechanic and know very very little; I am learning as I go because of this truck.

Just to clarify, resetting the oil life indicator going forward, it will not resolve the problem with a plugged filter, that's a dealer fix.
Believe the steps are listed in the owners manual around page 300 or so. Note For my truck, and it's not detailed in the SOP I have to make sure the driver door is closed.

Exhaust filters, is your truck stock or do you have an engine tune?

I change my oil every 10k due to the warranty, even though oil analysis tells me I can go longer.

You can reset oil life without changing the oil. There's the method of turning ignition to run and depressing accelerator 3x, or simply use the dash controls if you have the higher end EVIC.

I was raised to take every word a salesman said as a bald face lie and to verify what I wanted to know by other means. If you bought a dpf equipped diesel and thought putting around town would be great for it you only have yourself to blame.

I do not believe that a check engine light will keep it from regenerating, but I don't know, sounds like its probably your drive cycle.

Unfortunately modern emissions equipped diesels are horrible for stop and go traffic. It just doesn’t maintain enough heat in the exhaust to clean it out. If you want to keep it emissions intact then you well need to start doing a weekly highway trip. Or you can just get aftermarket tuning and remove the doc/dpf completely.

I did not know enough about diesel engines to know driving around town was going to destroy the exhaust filter and ultimately the truck. I wanted a diesel engine for reliability durability and MPG. If it did not have the filter I would not be having trouble with it. After the 3rd trip to the dealership for service I drive it roughly 60 miles every Sunday as fast as the flow of highway traffic will take me with 70 mph the minimum. I guess that is not enough. So I will have to waste more fuel and time every weekend just to (hopefully) keep it out of the shop.

My truck is all stock. Nothing extra added. I do not believe the check engine light will keep it from regenerating BUT that is what the dealer is telling me. I also do not believe the oil life monitor going to 0% will trigger the check engine light either but again that is what the dealer is telling me. The dealer says I must change the oil to have them clean the exhaust filter and I must pay for the exhaust filter cleaning because not changing the oil caused it. Technician also claims the oil viscosity DTC is low. Any ideas on what DTC is? I questioned how he determined the viscosity was low with no answer. I know resetting the oil life will not clear the filter but based on what the dealer is claiming the reason my truck is now sitting in their shop is because I did not change the oil when the life went to 0% which rippled to the dummy lights and filter getting full.

I have dash controls but I have tried resetting it without changing and it did not work. Maybe my door was open. Holy moly, never would have guessed that keep it from resetting. If I turn it to run and press the accelator do I have to push it all the way to the floor 3 times? Again I apologize, I am not a mechanic, I know nothing about vehicles and do not claim to.

Thank you everyone for your help and input. I do appreciate it.

Some cels well stop the truck from going into regen cycles that is true. But the oil life indicator well not cause a cel and the truck has no way of knowing what the oil viscosity is s that info is false. In order to figure out what is actually happening they need to figure out the root problem its likely you have a buildup occuring on the face of doc which causes excessive regens to occur. Whats your coolant level and color like, is it staying at the same level?
 
#11 ·
They want to blame the oil (code P1D30-00) this time because they have already blamed everything else the other three times I have had it in.

The coolant level is fine, with some in the overflow without being too full and the actual radiator is full. I do not know what color it is. I am sure I have lots of soot buildup all over the place based on what little info I have gathered from my reading. This dealer will never get to the root problem because they either do not know or do not care. Maybe it is simply my mostly city driving causing it. I was trying to hold on to the truck until 36,000 (24,000 currently) to keep from losing my tail on trade in value but it appears maybe it is just time to dump it and run.


Thank you

Here is the code, as read from ALL DATA. This is an online repair manual.
P1D30-00-OIL VISCOSITY TOO LOW
- When Monitored:
With the engine running.
- Set Condition:
The engine oil viscosity is too low.

I do not think the vehicle can actually monitor the oil viscosity. It sets when the oil life stays at 0% for an extended period of time. I agree with the other posters. Get the oil life
reset and drive the vehicle on the hwy in 6 th gear to get everything hot. Tow a heavy trailer if you have one. Best of Luck!

Sounds good. I will try resetting the oil life monitor and then driving the heck out of it. Surely 125 miles ought to be enough?

If I can't get the oil life reset I will just change the oil and drive the heck out of it then.

Wish me luck, I will sure need it to get my truck back from the dealer.

Thank you again!!!

GOOD LUCK. Keep in mind even if you change the oil you will have to manually reset the oil life monitor.

Oil Life Reset
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the EVIC after a single chime has sounded,
to indicate the next scheduled oil change interval. The
engine oil change indicator system is duty cycle based,
which means the engine oil change interval may fluctuate,
dependent upon your personal driving style.
NOTE: Use the steering wheel EVIC controls for the
following procedure(s).

Vehicles Equipped With Passive Entry
1. Without depressing the brake pedal, push the ENGINE
START/STOP button and place the ignition to
the ON/RUN position (do not start the engine).
2. Push and release the DOWN arrow button to scroll
downward through the main menu to “Vehicle Info.”
3. Push and release the RIGHT arrow button to
access the ”Vehicle Info” screen, then scroll up or
down to select “Oil Life.”
4. Push and hold the RIGHT arrow button to select
“Reset”.
5. Push and release the RIGHT arrow button to select
“NO” or “YES” to reset the Oil Life to 100%.
6. Push and release the UP arrow button to exit the
EVIC screen.

Vehicles Not Equipped With Passive Entry
1. Without depressing the brake pedal, cycle the ignition
to the ON/RUN position (do not start the engine).
2. Push and release the DOWN arrow button to scroll
downward through the main menu to “Vehicle Info.”
3. Push and release the RIGHT arrow button to
access the “Vehicle Info” screen then scroll up or down
to select “Oil Life.”
4. Push and hold the RIGHT arrow button to select
“Reset,” then select “NO” or “YES” by pushing the
RIGHT arrow then push the RIGHT arrow
button to select reset of the Oil Life to 100%.
5. Push and release the UP arrow button to exit the
EVIC screen.

NOTE: If the indicator message illuminates when you
start the vehicle, the Oil Life indicator system did not
reset. If necessary, repeat this procedure.

The dealer is "contacting their field rep" so I believe I have made a little headway. Thank you; thank you to all for giving me enough ammo to call them out on their b/s claim of the check engine code of poor oil viscosity and the oil life monitor.

I will definitely add GDE and drive the truck more to get out of this 6 - 8 month cycle of taking it in for service because of a full exhaust filter that will not empty.

Thank you,

Just to further clarify my truck just went over 10,000 Mikes on the oil life indicator and NO check engine light. So pfffffttt to you dealer.

With GDE you will go 700 to 800 miles between regens instead of 80 to 120. If I was having your issue I would pay $50 more fore the Regen message so you know when you are at 80% and a Regen is starting. Then you can plan on a ride to finish a Regen. At 80% on a GDE tune you have more miles left to drive before 100% full then on the factory tune from 8% to 100%.

That is interesting. I have asked the dealer to reset / clear the check engine light and the electronic throttle control flashing light. I am sure they will refuse or want to charge me. I also asked them to reset the oil life monitor so I can drive it home without the check engine light coming back on throwing me right back to square one.

The oil life monitor is extremely frustrating because there is absolutely nothing wrong with my oil. I started having it tested after the 3rd oil change when the monitor was at 0% around 5K. I use Amsoil and they kept claiming the oil was still good and the monitor was wrong. I trust nobody anymore and since it is Amsoil brand I was afraid they would tell me it was good even if it was not. Now, I have my oil tested at 3 different places around 50% and again at 15% on the oil monitor with all three places so far having nearly the exact same readings. As a result, I am confident knowing my oil is good and the monitor is just a way to get people into the service department for more revenue with the bonus for Ram being whatever they do not want to warranty they can whip out the P1D30-00 viscosity code and blame lots of problems that should be free to the customer under their warranty on the oil.

The B2B,
Please let me know what brand and all particulars of oil you are using. If I could get the monitor to 10K I would be very satisfied with that.

Thank you

All, new to forum and first off, unsure if the site is working properly as I'm clicking on "Reply to thread" but nothing happens,,, guess I'm supposed to use the "Quick Reply" noticed just below the "Reply to thread".....?

Anyway, read entire thread and couldn't agree with Capt.Pete more, why would Dodge sell a truck knowing they may attract or make sales to those in or near a city (traffic, stop lights, on and off cycles of the motor etc.) without clarifying this during the sale or even on dealer sticker. I mean, my opinion is, they should at least list "For Highway use only" if the truck will constantly be in and out of the shop if it is not...right?

I'm commenting because I too am currently experiencing and not happy with. The result of a happy or pleased client is (in this case Ram owner) would be an issue free experience. The engineer who came up with DPF warning, timing and results should be fired in my opinion. Why isn't there a better warning or definition for this issue? So here is my story:

Bought this truck used. Planned on getting a full size but couldn't justify being the 1500 could do everything I needed, not to mention, the price I finally got the dealer down to made me feel like I was getting a good deal. It had 42,000 miles on it and I use it as a company truck running all over the US on sales trips and providing service. I have been happy with this truck (Average 24mph on the highway and 14 pulling my camper trailer) until a trip to Mexico for the holidays where I received a "Exhaust Filter at 90%/ Drive at highway speeds to remedy" (56,000 miles). Had never seen nor heard of this but was assured that the very little City driving I needed to complete (few trips back and forth to local stores/15 minutes round trip) during my last days here would not interfere as I would leave soon for a 650 mile trip. WRONG! Remote started the truck (As I always do with any vehicle to get the oils flowing at idle) only to find that it canceled on me very quickly. Jumped in the truck to find "Exhaust Filter Full/ See Dealer" along with something about the electronic throttle body. I decided to try to drive it to the nearest highway (Not close as, again, in the middle of a city) where i found that I'm stuck in one gear and can only get up to about 45Mph. Really? What a bunch of horse s###! I then realized that had I been in a traffic jam on the interstate because a crash, bad weather etc. This would have happened as I read this happens from not doing enough highway driving. What if I were hunting way back in the woods and a highway was 50 miles of putting back to..? What if you were stuck in this limp mode and needed to quickly avoid an accident by needing the response of the throttle..? So, here I am stuck in Mexico after driving my truck to the convenience store twice with this error present. Dodge locally here in Mexico can't see me today and am scheduled for tomorrow morning, but how much do you want to bet that they will have no idea how to reset the computer so that I can drive my 650 miles hopefully regenerating the DPF? I hope I'm wrong and this Mexico Dealership will quickly get me on the road again. However, I can't help but think this all could have been avoided if the error would have stated the situation outcome better. If it would stated that it was an emergency to find a highway and drive for many miles and I was going to be trying to explain to a Mexican Dealership how to fix my Diesel truck which may very well be their first time seeing one, I wouldn't have assumed that this could wait until my long trip scheduled soon.

Anyway, done venting I guess. If anyone knows a way to reset this regen so I can get home, please respond fore if not, I will trading this truck in if and when I can get it home as I can not deal with a truck that goes into limp mode if you drive in a city.

Welcome to the Forum.

If I'm understanding you correctly, you failed to drive on the highway when the truck directed you to and somehow it's the truck's and FCA's fault?

The dealership will likely force a Regen and you'll be set for your trip home. Don't ignore any more dash messages, they're there for a reason.
