What percentage of cars with this engine have tre problem. I just bought the 2019 b220 4matic with 70k km. For now it runs wo problems.
Great video lot of learning. Also recently mercedese covered the head of all those 2.0 engines produced in 2021 and 2022 check with your dealer you might qualify for an extended 15 y/150k miles warranty on those heads. I also had the same issue which they covered 100%
Doing my first one this week, just waiting for the cylinder head. Nice video!
Thank you and good luck 👍
I have a GLB 250 (2021 model and 22k km). The engine check light has turned on. Service said it is because of fuel system. But no exact reason. Then I made them turned the check light off 3 days later it came back on Then 1 week after it turned off by itself.
I used the for 200km and full the tank. After 2 weeks light came back again.
The average consumption is 17liter / 100 km. Isn’t it too much? What could be the issue?
Hello, and yeah it could be related to the valves but without knowing codes and actual values it's hard to say exactly
Antifreeze boils at speeds of 80 miles and above.
What kind of breakdowns can there be?
can you tell me the reasons for overheating of this engine?
Thermostat! The original Thermostat has a wire filter which gets a lot of dirt collected and don't let coolant pass through. You have to replace the Thermostat. The new Thermostat doesn't have that filter in it. So make sure it's off when you get the old one out.
Thank you so much for the answer! Be sure to recommend your CZcams channel in your blog.
is this a frequent problem?
what elements need to be dismantled to replace the thermostat?
Yes, if the Thermostat hasn't been replace. But once the new one is in, it will last more than the original, due to the elimination of that dirt collector filter
where did you buy what you used to support the engine?
@@aswoopingjezus6044 I just use flat metal plates between the lower engine and the aluminum bumper frame. Some people just use a jack and leave there or a jack stand
thanks bro
Doing my first 260 head tomorrow this video helped forsure
Good luck
what is the manifestation of this breakdown in the car?
This cylinder head issue turned me away from mercedes. I just cant take out a 50 k loan for this crap
Yeah I hear you. This happen mostly within 10k miles to 40k miles which would still be cover under the warranty. Once is done you don't have to worry about it. They made the parts better. This is why you don't buy the 1st or 2nd year of that model. Wait at least for the 3rd year.
So its a 1 time fix?
Any word on if the 2023's have fixed the issue?

Unfortunately I just limped back to the Mercedes dealership this morning for my 2020 GLB 250's second head replacement @ 40,367 miles on it. The first failure happened at just over 15,000 miles on it. 😳
How much did it cost
This job at the dealer roughly $7k
Hey there whats the tightening torque for the camshaft sprocket center bolts ?
For the camshaft adjuster control valve center bolt is 18nm and a 45 degrees turn.
Thanks so it's a replaceable item ?
@moonkef well yeah, anything in the engine is replaceable
How do i make sure the timeing is correct before takeing it apart?
Crank pulley at OT and cam sensors remove you can see through the holes on 1 side an u shape on other side a line metal mark.
great work
Thank you!
Is this issue on the M264 as well?
Yes same problems
Did the new head come with the new valves installed or did you have to install them?
This one came with the valves. The only thing you have to swapped are the rocker arms.
Was the oil change a part of warranty replacement? Starting from what MY cylinder heads were changed?
No unless you bought a service package.
@@nelynel83 thanks! Are my23 cylinder head fault free right now?
No
My brother has a 2021 GLB 250 4Matic ... does this car have this type of issue? If so, how many miles will it take to start showing this problem? Will this issue be still under warranty? Thanks.
Yes, this vehicle will eventually have this problem. As long as the car is under the warranty, which is 4 years, 50,000 miles, which ever comes 1st. It will be 100% cover.
@@nelynel83 Believe it or not, he has only 10K miles on it. One more year for the factory warranty. When will this type of issue start happening? Please advise. Some comments below say the warranty is extended to 15 years/150k miles to cover this issue. True?
Yeah, sorry, there's no telling when this will occur.
They just told me that extension warranty does not cover this only exhaust valves not the head
Hey boss, great job. I have a 2021 GLB 250, 31k. Check engine light, took it to the dealership. Burned valve. Asked me for proof of receipts that I changed oil. I am assuming this is the same issue? This is what the dealership will need to do?
Yes most likely, with 31,000 miles. That's crazy right.
@@nelynel83 crazy indeed, made me very disappointed in MB. I purchased this make because of their durability especially with engines. I read that you said once it is changed it is all good, so that’s a relief.
What causes this problem? Which part is defective?
Also, y r the GLB so jerky when stopping and driving?
Thanks mate!
Mainly the valves, intake /exhaust valves. But meecedes so far is changing the complete cylinder head. And about the jerking, if you're talking about while braking, that would be the brake rotors been warped/ burn causes pulsation. If your talking about talking off and while driving that could be the rear differential, we been changing them for this issue also.
@@nelynel83 Nope not while breaking. Like when coming to a slow "almost" stop and then pressing on gas, it like jerks instead of a smooth acceleration. Is that rear differentials as well?
@Daiiisssy yes sounds like rear differential, you will hear a thunp as it gets worse,
Does Mercedes have a bulletin number for this defect? Did they replace your head free of charge?
You have to take it to the Mercedes-Benz dealer and they will diagnose the vehicle and if they verify that this is your issue. They will give you an estimate if your car is out of warranty, but if it's still under 5 years or 40,000 miles or additional CPO warranty they will repair at no charge.
Did Mercedes correct this problem for the 2023 model year vehicles?
No
What is the bolt tightening sequence on the m260? I’m in the middle of doing the head on my a35. I’ve seen alot of diagrams online for 4 cyls that show to start from middle of head and work your way outwards. Is this correct for this engine??
Thanks
Also is timing tool needed?
Yes, start from the middle and work your way towards the outside left and right
No timing tool needed. Just set the crank to OT and take cam sensors out to see that intake has a the timing mark facing up, the exhaust will have mark looking like a U
Is it 80nm
@@anees7988 no 1st stage 10nm, 2nd 40nm, 3rd 90 degree turn, 4th 90 degree turn, 5th another 90 degree turn.
What is the new part number for the updated M260 cylinder head? My car is out of warranty, 68000 miles and has a leaky cylinder head . MB is charging me 9000$ to fix it.
You should be covered
warranty is exteneded 15yrs/150k miles to cover this issue. they should fix it under warranty
@@tman984
Correct. I just got the same letter from Mercedes informing the warranty has been extended to what you stated
@@robsan9017when did yall get this letter I had to replace my cylinder head and pay out of pocket.
@@tman984how did you know this I have not received any info on this
New cylinder head include Head Gasket ?
Yes, the new cylinder head comes with the gasket inside the box.
@@nelynel83 only gasket or include other parts ?
Well, sometimes the cylinder head comes with the intake, exhaust valves and valve stem seals in it and head gasket. But sometimes the cylinder head comes naked just the block. I guess it depends on the model. Ask before you order it.
Why you didn’t send to workshop ?
It’s not possible for this head to be fixed in workshop?
I have this problem in my car in cylinder 4 also m260 engine, shall I?
I am the workshop! I am the Mercedes-Benz technician! If you have the same problem, yes, you should!
I mean , the same head I have can’t be fixed without replacing?
Can it be fixed?
@mohamadismail9142 you can try replacing all the valves.
Please one more quick question
How did you remove the tensioner holders ?
The two parts that holds the tensioner
How do you remember which bolt goes where?
Experience lol
Mercedes-Benz requires high experience as stated above! Or just put baggies and label with sharpie lol
Give me 60's or 70's full size chevy american car over this garbage any day of the week.
Lol I hear you
Lol first day having one of these and it prob needs this. pos.
M260/M264 are plagued with cylinder head problems.
Yes they been bad! And I thought the M271 was the worst. But at least the M271 lasted about 90,000 miles until they bent intake and exhaust valve and gears.
@@nelynel83 How many have you replaced?
I'm done 6 on the M260.
@@nelynel83 My aunt had hers replaced last month right outside of warranty on a 2020 GLB250.
No way....how much she pay for that if you know....she should contact and complain with Mercedes-Benz
