Hi guys! I have a problem with my W164.
Some 10 days ago i found the car with the two clocks and the info screeen between them on and cluster lights flickering, while the car was locked. I return to my garage and lock the car again - everything went off but in 10-15 seconds the cluster lights flickered and the dashboard wen ON again.
I unlocked the car again and lock again and everything went Off. Few days later the car was with drained battery. I jumpstarted tha car and went to STAR diagnosis, they said there is faulty battery. I changed the battery and 3 days everything was perfect - locking the vehicle, all lights went OFF.
But after 3 days in the garage i found the car again with the dashboard clocks and info display ON and cluster lights flickering. Went to STAR again, this time they said "Well it's the dashboard you have to change..."
I drove bacj to my garage and lock the car just for fun and.... everything went OFF. I checked the car 5 hours later and the dash was OFF, no flickering lights, no lit up clock. The next morning i found the car again locked, with the two clocks and info display ON and flickering lights...
Any suggestions, friends?

When you took it to Star, did they charge you and give you a print out of the codes that they found?

harati

Yes, they charged me and i ask them about the codes they found. It was in one the official services here and they gave me the codes. I'm from Bulgaria so the codes are in English but the explanations are in Bulgarian.

Maj. Dundee

If you got a bill the codes should be on that bill. Post a copy of the bill and black out all your personal information.

harati

Is the VIN number a personal info?

Maj. Dundee

I don't know what you mean.

Maj. Dundee

Then post the bill and I'll translate it in Google translate.

harati

The WDC number of the car.

Here is a video of what exactly happens :

Those are the pages with the error codes from the official STAR bill.

Maj. Dundee

I'm sorry I put you through the trouble, but I was not able copy and paste these words on Google Translate.

Could you please translate what the highlighted area in yellow say?

harati

OK i will try :

1. XALWA-R Xenon headlight in right
Code 9009 The data is not coded or it's been coded wrongly
2. DBE - Ceiling module
Code 9005 The electronic control module N70 was divided by terminal 30
Code 9600 The sliding hatch is not standard
3. AUDIOGATE AGW (MOST- system for multimedia data transfer - data management, diagnostic gateway, radio-tuner)
Code D117 The given and the actual MOST configuration is not the same/different

Maj. Dundee

The bill that you posted is that from the first time you went to Mercedes?

How did they decide that a battery was needed?

harati

This is the second bill. The first i don't have it - my wife was with the car and they didn't gave her the error codes bill nor she was subscribed as a client cause the car is on my name... :/

P.P.
This bill i posted here was made after the main battery was unplugged overnight! So some error codes could be from this.

Maj. Dundee

But they must have given your wife a bill.

harati

Well yes, bill for the inspection but without error codes. But that's not the problem.
Today even a signal on dashboard that "The rear left turning light!" appeard. When I turn on the blinker, the relay starts to click quickly, as if the bulb has been burned. But when i checked the bulbs where OK but the blinker clicks faster. When i switched off the ignition and turn it ON again everything was OK. I switched it OFF again and got out of the car, left it as it was and the headlights went OFF, the dashboard went off... but for a couple of mins and then starts to blink and lights up again (like in the video above i posted). I will remove the dashboard this week for inspection but... Still i think it's not from it.

Maj. Dundee

When the left blinker was on the dash, did you get out of the car and see if the left light was blinking also?

Are you still getting a battery drain or do you disconnect the battery?

harati

The left blinker was on the dash, the warning bulb was on the screen, but all the left side blinkers was ok.
Yes, i disconnect the battery

Maj. Dundee

Try this test. With the key out of the ign, remove the two fuses shown, which power up the Inst. Cluster, and leave the the battery connected.

Then attach a volt meter to the jump start points underneath the hood.

Note the battery voltage at the start, then monitor the voltage every hour or so and see if there is a consistent voltage drop. If there is, then replace the two fuses.

Maj. Dundee

Also, while you are driving, do you get a message in the Inst. Cluster that rear lights are working off of the auxiliary circuit?

harati

No, no such message.

Maj. Dundee

Are you going to do the test?

harati

Yes i will, but later today - I'm on work and wil lfinish in 6 hours. After that i will try the test with the fuses. Thank you!

Maj. Dundee

I just thought about things and here is an easier test that I completely forgot about.


Just follow these easy steps with the key out of the ignition. Leave car for about 1 hr. before testing. and just do it to the two fuses in my previous post and check these two fuses which are for the Overhead Control Module.

harati

OK i will do it tonight and let you know what's going on.
Thank you again!
