Fault just popped up on instrument panel

[Gozoman]

My car is a W204 C180 Blue Efficiency.

Was just out running a few errands and got something up on the panel stating that the Pre-safe system had a malfunction.

I have an iCarsoft MB11 so I ran a full diagnostic and the following fault codes appeared.

C221500
B005013
520908
990915
U041600
P063500
B210F00
C155

Now obviously I could go to my Mercedes dealership and let them sort it but I had a bad experience before where it turned out to be a very simple problem that ended up costing me around £600 that I could have fixed myself for £15! On that occasion every light on the display came on so obviously I was worried. I was out at the time and not far from the dealership so I drove there and got it fast tracked. It turned out to be a faulty speed sensor on the passenger side wheel so I told them to replace both sides. The charge was just over £600 and when I checked that evening I discovered that I could buy a new German made sensor for £15 and it would take me about 15 minutes to fit! So I'm just a bit concerned that I could end up being charged hundreds for replacing a fuse or something! Any advice would be appreciated.

I've had pre-safe show on my car. It went away by itself, I'd not worry about it unless it continues to pop up again ....

I sometimes have the same message come up temporarily if someone sits in the passenger seat of my 2008 W204. It goes away and local indi reckons it is a wiring issue or passenger seat pad connection issue. It does not persist so I am not concerned.

Funny you both should say that as it hasn't appeared again. What does show up is a side view of the car with the rear seats in solid white and the front passenger seat sort of grey, with three human like forms in front. I assume this is referring to three seats being good and one with a problem, the front passenger seat.

Some Mercedes show which seats are occupied and which seat belts are on. Handy if you’ve kids in the back so you can tell they’ve this belts on.

Yep mine does that but it hasn't put the warning up before.

Hi did you find out what the 990915 code was and how to fix? Thank you
