Your dashboard says service B overdue or
0:02
service A due and that little wrench
0:05
light just will not go away. I am Tom
0:07
from Car justify and today I am going to
0:10
show you how to reset the service light
0:11
on a Mercedes E350 in just a few minutes
0:14
right in your own driveway. A lot of
0:17
people get intimidated when they see
0:18
that service message. But you do not
0:20
need a fancy scanner or a trip to the
0:22
dealer to clear it. All you need is your
0:24
car key, your instrument cluster, and a
0:26
little patience. First, get in and close
0:29
the doors. Put your key in, but do not
0:32
start the engine. Turn it to position
0:34
one, which is the first click. You
0:37
should see your dashboard come alive,
0:39
but the engine stays off. That is your
0:41
starting point for the reset. Now, on
0:43
many E350s, especially models around
0:46
2010 to 2016, you will use the steering
0:49
wheel buttons to navigate. Look for the
0:51
little phone and okay buttons on the
0:53
left side of your steering wheel. We are
0:55
going to use those. While you are on
0:57
position one, press and hold the call
0:59
button and the okay button at the same
1:01
time for a few seconds. You should see a
1:03
special service menu pop up on the
1:04
cluster. If you do not get it right
1:06
away, do not worry. Sometimes it takes a
1:08
couple of tries. Just turn the key off,
1:11
then back to position one and try again.
1:13
When the menu pops up, use the arrows to
1:15
scroll down to assist plus. That is the
1:18
service menu Mercedes uses. Press okay.
1:21
You might see service data or full
1:22
service. Choose full service and confirm
1:25
with okay. You will see an option that
1:27
says confirm service. Select it and it
1:29
will ask for confirmation. Pick the oil
1:32
grade if it asks, then confirm again.
1:34
After you confirm, you should see a
1:36
message that says service confirmed or
1:38
something similar. At this point, turn
1:41
the key off. When you start the car
1:43
normally, the service message should be
1:45
gone. No more warning. It really is that
1:48
simple. If your model is newer, say post
1:51
2017, the procedure is a little
1:53
different. You often have a touchpad on
1:55
the steering wheel. You will still get
1:57
into the service menu, but you might
1:59
swipe instead of using hard buttons. The
2:01
idea is the same. Get into the hidden
2:04
menu, confirm the service, and you are
2:06
done. Now, if you try all this and
2:08
nothing happens, it could be your
2:10
software is different or there is a
2:12
fault stored that cannot be cleared
2:14
manually. In that case, you might need
2:15
an OBD scanner to see if there is an
2:17
actual issue triggering the light. Also,
2:20
if the car was recently serviced, but
2:21
they forgot to reset it, this will clear
2:24
that message. But if you have not
2:25
changed your oil yet, please do not just
2:27
reset it to hide the warning. It is
2:29
there for a reason. Do your service
2:32
first, then reset. To recap, key in,
2:35
turn to position one, hold the call and
2:38
okay buttons together. Navigate to
2:40
assist plus, confirm service, and you
2:42
are all set. A little patience goes a
2:44
long way here, and you save yourself the
2:46
dealer visit. If you found this helpful,
