I thought I have to post a thread as GLB (X274) are my fave SUV ever .
Well, what do you think of the new GLB if you have seen any on the net ?
Would you ever consider trading your GLB for the new one ?

From my point of view, I have noticed some improvements in the interior but two things would get a red card from me

1- It looks like a general common attitude fired away by VW is that on the driver's side door panel , they removed the rear window buttons . You have to press the REAR button to roll down / up the windows . Why ? For two cents . you automotive manufacturers render the things harder to operate . You have to press the buttons twice while you would do it easily at a touch a particular rear window buttons . Only old French cars would have it lol
Mercedes-Benz also look like to follow foot steps of the VW by deleting rear window buttons on their CLA, GLB . You're Mercedes-Benz , you're premium car manufacturer . Some would comment that we have a singe button or know for the door mirrors as well. Yes, but back in pre Ford Jaguar XJ40s , there were two buttons for the door mirrors . It was something that made me feel different and leave a WOW effect when I drove one of those junks
In a nutshell, deleting a button not just a door button is something I dislike
2- Pano roof . It looks great but no longer being able to open it is definitely going backwards to me . You have a pano roof but can't open it ?

Hi everyone,
I’m looking for some insight on a recurring P0304 (Cylinder 4 Misfire) on my 2021 GLB 250 4Matic (82k miles).
Background:
The car recently started misfiring on Cylinder 4.
What I’ve replaced so far:

• 4 brand new OEM Spark Plugs
• New OEM Ignition Coil for Cylinder 4
• New Bosch Fuel Injector for Cylinder 4 (purchased as Bosch aftermarket, not MB-branded).

The Problem:
I am getting a recurring P0304 and a "System Too Rich" tendency. After clearing codes, the car runs smooth for about 30 minutes, but after a hot restart, the CEL comes back within a minute from off state then start once again
Live Data at Idle (Fully Warmed Up):

• RPM: 700 (Steady)
• MAP: 32 kPa
• O2S11: 0.000 mA
• STFT1: -3.9%
• LTFT1: -14.1%
• EQ_RAT11: 1.011

The Stuck Point:
I suspect the issue is that I have not coded the new Bosch injector. I bought a ThinkDiag, but unfortunately, the "Injector Coding" function is not accessible/supported for my specific 2021 model year in the app.
My Questions:

1. Given that my MAP is 32 kPa at idling after ran 30 mins, can I safely rule out a burned valve? (I’m worried because of the P0304, but the vacuum seems too good for a mechanical failure).
2. Since I can't access the coding menu, will the ECU eventually "self-learn" the new Bosch injector’s flow rate if I keep driving, or is manual IMA coding mandatory on the M260 engine to clear the P0304 for good?
3. Has anyone had luck coding a 2021 GLB using a tool other than Xentry?

Any advice before I give up and head to the dealership would be greatly appreciated!
