Here, some real issues from an owner of 10 years here.
1. Sunroof will leak. It's not IF, it's when. And when it does, you can either replace the seal yourself like I did (it does require tools but I'm an engineer so..) or pay thousands of euros to have the whole thing replaced by the Mercedes
2. Starters fail since they're the most exposed component at the bottom of the car and will likely get soaked everytime you drive on wet roads
3. Doors rust (factory recall and warranty issued back in the day) and they rust so hard it almost doesn't make sense to repair them
4. Boot springs get tired and won't lift the door properly after 10 years
5. headlights are very inefficient and visibility is poor - LED upgrade recommended
6. Brake booster is weak from the factory so when it gets older, it makes sense to replace it before it gets even weaker
7. All major suspension components will need to be replaced at 200k kilometers intervals. Broken springs are a thing, as well as balljoints, shocks, arms etc.
8. window motors are weak, won't lift glass at satisfactory speed after a while - it's also an indication that the alternator is giving up.
9. car is very low in the middle due to DPF filer system so you WILL bottom out if you're not careful
10. Silencer tends to rust because it's not protected. I had mine changed and the old one basically fell apart as they were removing it from the car.
11. LCD screen will die after 15 years or so. You can replace it yourself by dissembling the instrument cluster, it's pretty plug and play. Replacement costs about 50€
12. Handbrake is shit by design, when you feel like it's giving up - replace the whole assembly. It's not worth replacing part by part.
Advice - change oil every 10k kilometers, change filters MORE OFTEN than the interval, delete ERG valve and flaps and change engine map to sth more efficient.
Also - preventative care. If you hear sth's off, address it. The car will give back to you. It's a great machine. The engine is bulletproof.
I've also heard that the CVT models are shit because the transmission is very weak, only 250nm max. The manual models can handle much more, 400nm.
For the Handbrake. I rejusted it after it becomes Worn. Its a bit complicated but you can do it alone. (Behind the Back Wheel on Driver Side) You can tight the Belt there with two screws. Its a bit Complicated, but Mercedes give an Instruction for that in the Internet. Other than that, i never had Problems.
B150 gasoline here with 160000km on the clock and zero issues.
Starter motor only fails if you have the "rimenstarter" generator on later models, facelift, my tiny starter sits on the engine above any water...its the alternater and then air compressor that goes boom if you sink it like a boat which never happened to me.
The gasoline takes 7,2L/100km measured with 50%50% mix town and highway use over 7years..
If you drive softly it can run as low as 5,5L/100km on cruise control with 90km/h to 100km/h on long distances.
Oil change very 10k with Rowe 5W40
@@kitecattestecke2303 Confirm. i run 5W40 Total Oil, and i drive most time 100km/h with 5,8l/100km with a B200 (Nonturbo) from 2006. Its a Perfect Car. High Quality, Silent, Smooth. I even would go with B150 or B180, i only dont like Diesel, i always go Gasoline on all cars in my life. I would switch to Electric in the Future, but not to diesel.
No real reliability issues then…
This is extremely accurate 😁
I have a 170, with 220k. I never have a problem. I love this car
I'm probably too Dutch to understand, but this video, that is supposed to be about the problems and weak points of the B Class, is almost completely about the good quality of the car.
The first time in this video a problem is mentioned is at 2:36, and even then only very briefly and kind of sugarcoated.
There is nothing wrong with mentioning the good points of a model, but when the title of the video states that the video is about the week points and common problems of the B Class, why not immediately start mentioning these things?
Again: maybe I am too Dutch too understand. We are very direct and we don't dance around things nore sugarcoat things. We believe that nobody benefits from saying A, while meaning B. In many cultures this Dutch way of communicating is seen as rude and inconsiderate (e.g. look at how Brits react to Max Verstappen's press conferences), and I understand that when I try to put myself in the position of someone who is from a very indirect culture. However, although I wouldn't want to go as far as stating that not being direct in communication is just as rude and inconsiderate, it's always good to try to see things from an other person's perspective.
Or maybe I will have to acknowledge that East is East, and West is West, and never the twain shall meet.
My Experience on this car B180 year 2006 since I bought it in 2019 it was only problem of leaking oil.since it was repaired I have no problem and the km is 230,000 I bought it with km 172000 I think it is reliable my cvt gear oil was changed once and it is shifting nice
10 years and counting, I use it daily to get to work ~20 kilometers one way, it literally never died on me, not once.
Bro, amazing video. Thank you so much for complete summary of b200. I am wondering have you heard any issues for reliability? I am considering this car for my winter car here in Canada. Thank you friend.
I have one 2007 B 180 cdi and is an ok car but negativ is turning and the low gap under the car, on winter road it is ok with ok winter tyers good luck from Norway
My speed display stoped working on my b180, 2018. Does annybody else has that problem?
Automatic transsmition is good, one of the best CVT. The car is comfortable and practic
Until you start having problems with TCU.
@@BenaliBoukadir please tell me about this, and what can possibly cause it, on how much kilometers usually happens, thanks
@dhani pianist sorry for the late reply. It's starts from 100k kilomètres. Both class A and B are known for their CVT problems. Expensive repairs.
@@BenaliBoukadir even if we change the oil before 100k it keep break?
@@BenaliBoukadirwell first of the oil change is 60.000km for cvt gearbox. Then atleast in germany if you are smart you send your electronic valve block to a firm that refurbishes only those, its cheaper and you wont need Mercedes coding in the same electronics
7g tronic will give problems with transimssion pacage so you have to fix it or replace it which will cost 1000$+ i had mine repaired i have 240k km and it was repaired before i did repair it again
Cvt gearbox boxes need attention at 100,000 miles seems to be a common thing
I don’t know what’s wrong with my b class after I got better problem now I can’t even switch it on
Maybe its too late but i will give my recommentedion.
I have b200 cdi 2005. 670.000km and its still good. There is problem with injectors and u need to check them if you hear any unusual sound. Also problem with LCD when engine get 60 degree C LCD DIES, when engine get cooler it will come back. In my country they say here is bad diesel and it take my 11/12l on 100km in busy town and 6l on 100km on highway. I will say that its good car (i didnt say good things because everything except this is good) but you need to be careful what you buying. Also if you dont care for car u can have problem with window electric if u press button to hard, and because of speed bumpers and holes u can have problem…
I just found 2006 b200 cdi automatik avantgarde 140 hp diesel 160k km, 4k euros. Do you think it is worth it. few times a year I do 900km trip in one sit. Is it comfortable enough for that, what is the sound isolation at 150kmh ?
Good car diesel engine
b200 turbo= 193HP
Good car manual gearbox
1,5l 95hp (B150 B160)
TCU problems on CVT, are not good.
CVT automatic gearbox always gives speed sensor fault. Not good.😢
On what kilometers?
Manual is not for mercedes, not comfortable...
I never had problemes with that CVT.
@@mart11000😂 manual only doesn't shift as smooth on BMW but is still build like traktor tank and if you drive more outside dense city the manual is a true hero
Lower fuel consumption as conversion efficiency is higher (shift efficiency on autobox might be higher for dumb drivers 😂) and it very reliable if you make oil changes every 100k Km for it . takes around 1,6L of gear oil GL3+ for 36€ done 😂
@@kitecattestecke2303 if you think about every penny and you are ready to lose driving comfort in order to save these pennies, then a mechanic gearbox is for you - I understand.
@@mart11000 In Europe almost everyone knows how to drive manuals in their sleep. There is no loss of comfort if you know how to drive
I owned the 180 CDI from 2006 to 2008, awful CVT gearbox, unreliable, did not work properly, and Mercedes had been waiting 2 years before telling me that I had to change the defect CVT!!!! so I bought a E87 118d BMW in manual shift!
Would you have to pay for the change?
@@alphadiallo6215 I refused to pay for any further expenses and I sold it at a very good resale price!
lol I had the same exact problem, except in reverse. My automatic e87 was terrible, always broken, and BMW was just hiding the problems every time it popped out. Bought b180 cdi (manual tho, my trust in automatics was broken beyond repair...) 10 years ago and it works perfectly till now.
Biggest problem with the B class is a bad mechanic.
I would say stupid and lazy mechanic...
It is not easy to make money on these and the work is harder because of construction but is not very hard 😂
Problem is called "unicorn"
If you not recognise or understand the sandwich concept you won't wrench on these
You are so right. I took my car in for a cold start-up noise, and they told me that I needed a new starter motor I then had the starter motor repaired.
The noise did not go away then I googled and bought a tensioner. This was fitted noise was stil there, so I was getting a ticking noise, drove my car, the machanic and asked him to listen so now they told me I needed a. Belt and a tensioner I sourced one the day I took the car in to have the goods fitted the Machanic had an emergency.
Thereafter, I took my car in to 2 garages, and both said it wad my timing belt my car has 100500 kilos on the vlock. Although it's a 2007, it's in very good condition.the cost between the to garages was R26. 000 I opted for the more expensive quote as this Company only work on Mercedes cars
@@marjoryferreira8089 Are you sure about timing belt or is it just the way the mechanic said to you. As far as I know the B Class W245 uses timing chain not belt.
Мне на такую машину никогда денег не заработать
You don’t know what you’re talking about.
TCU in gearbox breaks on all these models
On which kilometers?
@@toplespecah666 i dont know.
Its a thing that i have heard and read from many different.
Our did this at 190000 km
@@hunkenpunken then how much to fix, anyway thanks for your reply buddy!
@@dhanipianisttake out TCM send away inside Germany for refurbish unofficially which is below 300€ for sure
Or go to stealershit and get rekt with 2500€ ℅bill on all new gear coded to the car while it was only the speed sensors
So many BS information in this video I stopped watching mid video.
same here. I can't over the comments that say this is a good video!
Very poor transmission
On what kilometers happening?
@@toplespecah666 160k to 250k
it will give problems with shitfing , slipping gears etc
Some cvt gearbox have issue at 130 k others go further over 300k.So we wonder why? After I made some research to have long live cvt gearbox must change oil and oil filter at 50 K, gearbox and coupling converter use 7 liters of oil, check the level at 80 degrees after change it,ckeck the level of oil at the gearbox at 10 km when do the Service B maintenace, do not force the transmision until the motor is not warmed at least 60- 70 degrees, not make the kickdown accelerate pedal when start to drive, and not at last have a skilled good tehnician mecanic to make a corect diagnose when apear some issue. I drive an automatic B 170 ,whith alternative fuel LPG, have 210k , no cvt isue until now.
