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%
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?
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.
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?
@@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?
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.
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
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
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?
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.
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
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.
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.
@@nelynel83 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. 😳
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?
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.
