DD15 ENGINE common problems OM 472 MERCEDES BENZ

[@luashelton9320]

I'm going to spend my day off watching, and re-watching these videos. We are so fortunate to have these videos. This is pure brilliance! Thanks Francisco...(I'm a company driver)

[@lukasallen846]

Well I think that you have talked about all the problems that I have had with my 2012 freightliner cascadia with the dd15 engine. I purchased my truck new and just after the 500,000 warranty expired (514,000 miles) my cylinder sleeve cracked. 90% of the problems you discussed I have experienced. Excellent video and very accurate. If you plan to own one you better budget at least $30,000 per year into future maintenance. Trust me you will need it

I bet those that didn’t like the video is because the own a truck with that engine. I guess that I keep using my 12.7 another million miles. Thanks for all your informative videos. Keep then coming

[@EncouragingBuildingInspiring]

Your videos are super helpful, we appreciate part 2 DD15.

[@headfirst6227]

It's been a rough year for me. At 830k miles my coolant turned black and they replaced the egr cooler. That was $8k. At 910k miles there was fuel in the coolant. The shop said they pressure tested the cups and they were fine and the cylinder head was cracked. That repair was $15k. I can't wait till the cylinder liners need replaced.

[@joaquinmartinez9269]

Buenos dias don Francisco amaya grasias por ayudarnos con sus conocimientos en sus vídeos

[@661jaxx]

I’d like to say that you are correct about the common oil leaks on the DD15/13/16 engines. But other failures such as fuel pump failures are cause by customers or other repair facilities not properly priming the fuel system. Also simple maintenance can definitely lessen the problems drivers have with these engines, and with the after treatment system. I am an expert certified Detroit trained technician from California. I always do my best to try to inform customers about these engines.

[@whskypete33]

The DD15 is not a bad engine, most people still think the engines are pre EGR or pre emissions like the Detroit Series 60 (12 liter), N14, CAT. Those things ran forever, new engines require more maintenance. The things Francisco is mentioning, do not all happen at once but over time these are things you will encounter. Injectors will be your most expensive repair.

[@johnnysmith4514]

Yeahhh :) very good video. Man after watching this one oh man too many common problems with dd15 bro. Thanks for sharing

[@prevost8686]

Tell me one modern emissions engine that doesn’t have plenty of common “problems “. They all suck. You could take a Detroit , a Cummins, a Paccar, and a Volvo and delete the crap off of them and they’ll all give great service with good fuel economy.

[@doctordiesel5467]

No more than any other engine on the road as I have already stated elsewhere I rebuild more Cummins isx engine with significant lower miles than compared to the Detroit dd15

[@raulduran9204]

I have 2010 freight liner Cascadia. DD15. Overall it didn’t give me any problemas. I replaced the coolant container because it got cracked. I paid 135 dollars for it aftermarket. It didn’t fit completely I had to make some adjustment. I see the second inyector had a little leak. I will replace it ASAP. Thanks for the information.

[@yamanawrooz5132]

I love your videos buddy. Keep up the good work.

[@fixiu272003]

You are the man Francisco! Thank you.

[@keyboard101101]

A lot of these problems are leaking oil which is not a big deal. The Cummins ISX seems to have catastrophic problems that will destroy the engine. You pick.

[@doctordiesel5467]

You said it spot on I diagnose repair and rebuild all these engines and I'm in the middle of build on a isx 550 with the valve face half of it broke off and down in the cylinder 105k on engine the isx is known for broken valve stems valve faces worn out cam lobes spun cam bearings broken cranks dancing cylinder liners and the brass captive ahs in the newer antipolishing liners that erode and desinigrate I rebuild way more isx engines than driptroits and the Cummins have far less miles on them as to compare to the detroits aka(driptroits) last good Cummins with out all the major engine Hardline problems was the n14 series I work on them all for 10 plus hours a day and in those hours 6 days a week sometimes 7 these are my conclusions based on repetitive repair and issues seen

[@mahmoudyasin2494]

Had almost all the issues you mentioned in the first year, i bought the truck with 600k miles, its all started with fuel pump that destroyed injectors, dealer estimated 17k to fix, then oil pump, then injector cups that mixed fuel and coolant, then water pump, and a lot to mention, i worked on most of that my self and yet spent over $30k so far.

[@Канадскаприча]

Mahmoud Yasin The truck had 600 k miles or km?

[@arionnecoleman5867]

what year was the truck and yeah....600k or 600km?

[@satbir371]

if change feul pump before these all happened.then i can safe myself?

[@-J-C]

The biggest issue with fuel pump failure is drivers letting the fuel get less than 1/4 tank. NEVER let your truck go under 1/4 fuel level. You can tell if your fuel pump is bad you will hear a ticking noise from the pump or you will see bits of metal inside your fuel filter housing.

[@JZ-ek4tu]

At 4:20, the oil housing. I have buildup around some of the bolts of something like acid from a battery. Best way I can describe it. It's white substance with some color from what I think is from the coolant which is red. Is that something that be looked at? I also do have low oil pressure warnings that comes and goes when I start the engine. I push the accelerator and it stabilizes before it shuts off. Thanks for your help!

[@garyhoyer5689]

My 2009 DD15 had the turbo replaced and a reman DPF filter installed by Freightliner 14 weeks ago.I had no issues for 12 weeks. Then another problem started happening. The regen cycle going down the road changes noise levels - quieter during the cycle and noticebley louder when the regen cycle is complete. This is normal. What is not normal is that now, at the end of the regen cycle going down the road, right when the noise level changes I get a check engne light. The light will remain on until I shut the engine off. When I restart the engine the check engine light is out and stays out until the end of the next regen cycle is complete and then I get the check engine light again. This doesn't happen every time but more often than not. I was able to get to my regular mechanics garage once with the check engine light still on. There had been 15 instances of a high temp on something. Sorry I don't recall the entire error message. They used a computer to force a regen and all temperatures remained in the normal range. I ah no issues for a week, then it started acting up again. I think that the regen cycle is not being completed as it should. I've driven this truck over 300,000 miles and have never changed or cleaned the dozer injector that you did in one of your videos. The truck has 907,000 miles on it now. With what I've written here do you think it might be the dozer injector or am I off track?

[@nelsonmendez7893]

Honestly after watching this video don't want to buy a truck with dd15 engine

[@Thorsrival]

Do you have any ideas as to how to hookup bypass's oil filter on DD 15 filter maker hookup on turbo supply line and I didn't like that

[@prevost8686]

Those are not oil leaks. It a DD marking its territory.

[@doctordiesel5467]

Aka driptroit

[@pera6356]

Hi Brother thank you for all helpful videos , 2014 Cascadia DD15 , I have leak in oil return line ( the one you mention at time 6:55 ) , is there seal or what? can I fix it by my self or it complicated process? last question what cost fixing it ? thank you

[@franciscoamayaYT]

Yes, it is easy. Use 13 mm socket to remove the pipe bolts (3 bolts in total) and replace the seals

[@red66chevy]

common dd oil leaks, DD13 cam housing cracks and leaks oil, DD15 cam housing leaks oil, coolant module, oil pressure sensor, oil pan gasket, crankcase breather, depending on year fuel pump, air compressor. DD is just like every other detroit they leak oil. later year front crank seal housing are aluminum and errode causing oil leak at front of oil pan. model year 13 and older replace your oil pick up tube O rings it will save your engine.

[@dwilburn1928]

Holy shit...you named every problems I've had with my truck. Smh

[@jddiesel7409]

Demetrius Wilburn Cause that's what we see with them all the time. I'll throw injector cup seals and air compressor coolant lines in there too. let alone the emissions problems.

[@350buickregal]

My mother drives a 2017 Cascadia believe its the DD15 engine. Would love the learn how to PM these big boys. Worked on gas all my life tho.

[@luashelton9320]

If your Mom is an owner operator , and you learn to PM her truck you will be an absolute godsend. Drivers are exhausted, stressed out like you can't imagine, and most are in a lot of back and hip pain after age 40, which makes them ripe for injury doing own PM on their one day off that's also laundry and Walmart day. On modern trucks we need DPF system wizards, bigtime. Love your enthusiasm Rice Man!

Gracias paco :)

[@zena0002]

Thanks for this Video I've learned a lot about what to expect from my 2015 DD15 engine (525000miles) . My question is if the cylinder liner is broken, will the check engine light come on??? I have white smoke coming out of the breather and penskee is replacing the turbo (MIL on chk engine not on) didn't see bubbles on deepstic. Heard a popping noise before the smoke started

[@kingtruffelz]

This is a EPA 10 DD15, 90% of these oil leaks and o-rings getting hard, etc have been fixed with updated gaskets with the 2014 engine year. (2 fuel filters instead of 3)

[@JosephArata]

EPA2010 was the first generation and almost all of the new production issues they found with it, were fixed as you said in EPA2014. They sell most of the update kits that fix EPA2010 engines still from the dealer. They sell a retrofit for 3 filter to two filter housing, changing it to the new 2 filter housing extends service life of the fuel filter.

[@CaliforniaCareerSchoolAnaheim]

It has DEF But I think it has two diesel particulate filters under the steps.

Ok, do you have the DDDL software?

I’m in the process of buying a 2014 freightliner with DD15 and this video is scaring me.

[@doctordiesel5467]

Its scarier to have a Cummins isx or x15 engine with its abundant engine failure issues like broken valve faces or broken valve stems and their brass cylinder lines which erode away and the line drops down blowing head gasket crankshaft snapping at balancer and in-between cylinder 4-5 and carbon polishing issue that's where newer engines and rebuilds now put in the anti polishing lines with the captive brass shit shims and their cam lobes wearing out injector side most often I'm in the middle of a isx 550 rebuild now valve face broke and it ended up tearing up the line piston and took out the turbo with the debris only 105 k on it is much rather have a Detroit I rebuild far more Cummins at lower mileage than I do Detroit's where I work

I am driving a 2012 Freightliner Cascadia dd15 , we by used and we fix everything, but i will be driving or parked and it may randomly cutt off!!! I mean total power loss, if I am rolling with a load 40,000+ lbs and I am rolling on the highway it cuts off bad, like 3 or 5 times, sometimes it gets bad, but if I am rolling it will try to power 3 times or 6 times and then it will come back on, all while I am rolling on the highway... I am now at Stoops Freightliner, but they couldnt find the cause, but these guys never test drive it to duplicate the problem!!! One of the owners, the $$$ guy said close it out after diagnosis, I think to save money, cause they want to give me another truck in a week or two, but I think they can fix it... Do you have any idea what could be cause of it cutting off? I did like already subscribed and shared on FB... Let me know what you think papa ?? Gracias Amigo!!! Peace and Love!!!

@@foxbodyguyeightyeight3672 well as I stated elsewhere I rebuild many low miles as in under 250k Cummins isx qsx and their latest pos x15 engine most of the Detroit's I rebuild in the 750k and up usually close or around a million miles occasionally a 500k line splits but its not as abundant as the Cummins in the middle of a isx 550 rebuild now valve face broke off down in cylinder 6 had the piston for appetizer then the liner for entree and for desert sent shrapnel through the turbo 105k on engine and this is not uncommon and their captive brass liners shim that don't last long in the anti polishing liners and blow head gaskets broken cranks worn out cam lobes pounded out liner mid stops from cylinder liner movent not overly impressed neither is paccar that why they had daf engineers a company they bought come in and design engine for them and build it themselves to start to get away from Cummins engines like ford to international on the power strokes I work diagnose and build them all I would take a driptroit any day even our big wreckers with the Cummins kenworth are nowhere as reliable as the western stars we have with driptroit power plants

@@doctordiesel5467 maybe I'm just lucky but while I was with that fleet the Cummins was fine and the Detroits were constantly having emissions issues but also these trucks were vocational low mileage high hours all pto work so I guess it depends on what you use them for?? Can't explain it I'm just stating my personal findings

Has anyone Experienced main bearing or connecting rod bearing failures within 24 hours after an oil change on the OM 471 or OM 473 engines? Is there a special procedure after the oil and filter change to prime the oil pump or the engine lubrication system ?

[@gilgil9342]

Hey Francisco am having this check engine on my dd15 say engine high code 128s155 00. What would be the problem.

[@jasvirsinghshergarh]

Hey Francisco.....my crankcase breather is dripping oil....Is this the time that need to change and if i need to change that is there any filter that need to change or i have to replace all assembly??????

[@franciscoamayaYT]

You have to replace the whole assembly, Freightliner dealer or Detroit Diesel dealer don't sell a service kit.

[@jasvirsinghshergarh]

Francisco thanks a lot

[@InstantAdviser]

I've had half of this problems

[@imadahmmad1965]

Good thanks

[@CaliforniaCareerSchoolAnaheim]

We used this procedure on this truck and one other that had the same problem. The other truck was fixed but this truck continues to have this problem. We also cleared any blockages. Any other suggestions?

[@franciscoamayaYT]

Does the DD15 has DEF?

[@gilmerdeleom1136]

En cuanto sale la bomba para echarle discel la los filtros disculpe?

Why is changing those injector line seals very expensive?

[@franciscoamayaYT]

No, the injector line seal is not a expensive job. Maybe line $500 maximum. No more than that.
