2017 GLS 450 Service b
I have always went with either Mobile 1/Motul/Liqui Moly depending on which car I'm changing. For my GLS450 I went with this kit for oil and filter https://www.fcpeuro.com/products/mer...61800009-7l-ml
You can get OEM brand Kengst or Mahle for air filter. https://www.fcpeuro.com/products/mer...gst-2760940504
For you cabin filters you can get Kengst or Genuine Mercedes which provides you with all 3 filters for cabin filters. https://www.fcpeuro.com/products/mer...des-2928300000
I recently purchased a 2017 GLS 450 as well and it has 70k miles. I need a service B and my local dealer is charging me $800 for this service. Given that the car has had service up to 64k miles at MB dealer throughout its life should I just bite the bullet?
Replace oil with liqui moly leichtlauf 5w40
Add Liqui moly MoS2 Anti Friction Engine treatment 2 cans
Add liqui moly Pro Line Fuel System Clener to gas tank
Next Fill up add DI Jectron Fuel Injector Cleaner
In addition B service calls for brake fluid flush which I did. (I bought a machine)
My car was also due for engine air filters so those were included in the cost above along with cabin air filters




After I press the start stop button once with foot off the brake
On the old odometer screen
I’m pressing the answer phone button for one second
Then, within a second, I am pressing and holding the OK button for five seconds
The screen t changes to reset trip odometer and nothing but nothing else.
Any thoughts or experiences with this issue?
