Bought this 2019 in the first quarter of last year with 17,319 miles on it.

Last Oct it was due for a oil change at 25k miles and got that done at Mercedes.

After the change in Oct, I noticed the Assy/Plus said next service was due at 20K mies or a bit over that 20K. I looked at that and told myself "that isn't right' somehow, if the oil changes are still at every one year or 10,000 miles.

Took the car by my Mercedes dealer a couple of days ago just to ask why the Assy Plus said service due in 14,500 miles. The service assistant was puzzled but also looked at the total mileage and advised service on the oil was now due because the mileage was now 35K plus a few hundred.

Took it in yesterday and got it serviced for oil and wheel alignment plus checking for bent rims The advisor told me when i picked up the car, that they had a NEW way of doing Asst Plus. I bought that idea for a while. I noticed today the Assy Plus says Service BC due in 24,700 miles. I'm thinking BC stands for Big Cash.

So, the question is: do any of you know about some New Way of setting the Assy Plus other than the next oil change at every 10K???

 

Dealers always forget to reset the service reminder. I always check that after a service and change it myself if it is not updated.

 

HMMM, it was reset, but reset to 25K plus miles, not 10K miles.

 

scroll down to Assy and reset.

 

Went for an approx 300 mile drive Sat. After I got back I noticed the Asst was now SERVICE DUE 360 DAYS. So, I thought all was just fiine and dandy.....until...... I just now went out to the car and it, ASSY says next sercive due 24,400 miles.

Not happy but not to sour about this. I just have to remember It was serciced at 35K and deak with it. Then again......there's something wrong with ASST PLUS. I notice a person over on the GLS forum has a similar 'problem'.

 

Applicable service sheet and reset.

 

I have an early built 2019 S560 with the same issue. There is a service bulletin for a software update to fix the incorrect 25K mile service interval.
Found it here. https://www.tsbsearch.com/Mercedes-Benz . Search for

TSB LI00.20-P-069865

Titled - Service data incorrect, remaining distance to service initialized at approximately 25000 miles

Thank you and KingTiger.

After I wrote my last post, showing 24,500 miles Assy Plus......a day later it said Service due 359 days. May be back to 24.500 by tomorrow.

So......I'll copy the Service bulletin and show it to the sercice advisor who said 'it's just a new way of indicating service intervals" and while there leave the car so they can find out why, when I'm making call from the car, the person on the other end of the call says i'm going in and out with my voice. Call being made thru the S560 microphone and car speakers. I hear them clearly. It's my transmission that is at fault.

Also figured it's probably a problem with the micophones. When using Voic Command to Navigate I've notice the Nav does not seem to hear me the first time or gets the city sooooo wrong it gives me four cities to pick from that are not anywhere close to where I indicated I wanted to go.
