You reset the ASSYST correctly.My ASSYST is set tot he 10,000 mile oil change interval. I must have reset it incorrectly as it used to analyze the oil and go ~15,000 miles between oil changes. How do I revert the system to the NON-10,000 mile standard?
You can take to the bank that my advice and input isn't 100%. In this case... you should believe me.OK, I hope so.
I mostly don't need to add oil between changes. For some reason at one time I did need to add maybe 3/4 quart before an ASSYST change was indicated. I too was happy to see the miles to change indicated by the ASSYST go up a bit. It really does monitor oil quality and not just engine speed, hours of operation, etc.I was able to top off my oil level and the miles to oil change would change too. Pretty slick monitoring in my Barney Rubble opinion.
For those who may be interested, this is what MB says about ASSYST.... It takes one measurement and extrapolates on all the other factors which affect your oil's ability to protect the engine. ...
In my early days of the cycle the key, push the buttons, cycle the key, countdown, pound the steering wheel, slam the windshield, repeat... dance learning curve I screwed up on many occasions. My ASSYST is still working fine.Old thread, but I have a question.
When I first bought my '05 Sprinter, the ASSYST went to 14,000mi before requesting an oil change.
I changed the oil/filter, and followed the reset procedure, but It didn't "take" the first time (I probably screwed up the procedure), and the second it did, but took 12 seconds for the procedure, and showed "10,000m" in the window. I just read that the limit is 10sec for the reset. The paper said that if you screw up the reset twice, you're screwed....
Yesterday I added 1 quart of Mobil 1 with the ASSYST countdown verified at 3400 miles. Today the countdown indicates 3900 miles. The new oil caused the ASSYST to notice and add 500 miles to the OCI countdown....
On a recent drive to Florida the oil level went low enough to allow a quart of oil to be added. I added 1 quart of MB228.3 spec oil with the ASSYST miles verified at 4750. After driving some time I again re-checked the ASSYST countdown. It rose to 5250 miles. My opinion is that it noticed the new oil quality and extended the OCI by 500 miles accordingly.
Use ASSYST or not. It doesn't matter to me.

3.12 ASSYST Active Service System
With a production breakpoint of February 1997, the
previous maintenance system for passenger cars with rigid
intervals was superseded by an Active Service System
known as "ASSYST".
Beginning with the W 210 4>Matic in 02/97 and phased in on
the remaining model series as of 06/97 (except G 463, 09/97)
the introduction followed.

> WIS (microfiche) overall system description,
"ASSYST" makes it possible for the first time for Mercedes>
Benz to have service intervals of up to 40,000 km or 2 years
(min. 15,000 km or 1 year). The system takes into account
individually the driving style of the customer by evaluating
engine speed, engine temperature, engine load and time. The timing
of the service required is calculated
and the due date is displayed to the customer in the instrument cluster.
There is also a sensor which monitors certain oil parameters.
