Hey Folks,

Got a tricky ques regards whether or not I need to do the service C -
I didn't drive that much on my 17' GLE350 (traveled a lot for work) - he only has 1000 miles but it's exactly one year since I purchased the car. The service C light is on now, do you suggest to reset it or bring to dealer to really perform the service?

thanks

John

It can be reset - and each time it is reset - it moves to the next service.

If you want to reset yourself - this link instructions might get that done on your GLE - it's late and I am have fuzzy thinking..

Oil should be changed after a year, it still has additives break down and accumulates moisture and contaminants, especially if you don't drive the car much or make frequent short trips.

I'd suggest just getting the oil and filter changed, rather than paying full pop at the dealer for a "service" which is largely just an oil change.

I tried this for my GLE, and it didn't work fabbrisd1. It asked me to reset the trip odometer, and I didn't get the ASSYST menu to pop up. Maybe I did something wrong.

Thanks ! The video tutorial was great.

Can you tell me how? I followed the video but it keeps asking reset trip ..I can't get to the assyst menu

Hi JohnBest,
When "TRIP' is highlighted use the "right side arrow," and tab over to "SERV." From there scroll down to "Assyst Plus", and you should be able to reset from there , if you are getting the warning message.

Thanks but didn't work. I was able to select Assyst Plus but it keeps came up message of "Service C due in 30 days" ..

Wow, you are right. Let's keep looking. Maybe there are service techs that could help us out.

Hi JohnBest,
​​​​​​​ Try these instructions for the w166 which is what we have.

Thanks but still doesn't work. I long pressed hold call and within 1 sec hits ok. Still it doesnt bring up the Assyst menu. Anyone else having this problem?

ItalianJoe1

That's the way it works, are you sure you're on the basic odometer screen? Doors and hood closed? Position 1 on the ignition, not fully on?

JOHNBEST2017GLE

Yes, basic trip od screen. Position 1 not fully on. Just it keeps reading that.

ItalianJoe1

I reset them every day, you're missing something. It's hard to know without actually seeing you do it.

You are pressing and holding the call and then also pressing and holding the OK within a second, and holding both until the menu pops up right?

Hey guys Thanks a lot! Finally got it!
I think how I did was I switched to 2 instead of 1. very important! and now it's done.

ItalianJoe1

Glad you got it, what was it that was giving you the problem?

JOHNBEST2017GLE

I figure out the problem is I switch on to "1" instead of "2"
