Hazard lights flashing after car is locked?!

[Benzito]

Hello MB Experts!

I was wondering if anyone could provide some insight, when we lock our 2000 C320, the hazard lights start flashing at double speed, and continue flashing until the car is unlocked again? (No alarm sounds). We've tried disconnecting the battery, but still no luck?

Please please help!!

Many thanks!

My 02 C220 coupe has started to do the same. Any suggestions as to why?

I have no C320 for 2000 as this would be a 202 I think Is it a 203

and the c220 will be a 203 I think

Please confirm

Hi,
Malcolm needs to know what model/body shape your car is.
W202, (C Class) 1993-2000 L to W Reg.
W203, (C Class) 2000 >

The c220 is a 203, they didnt make a coupe in the 202 c-class

Thank you young man,I guess that I should have come to that conclusion myself

Wot are you thinking malcolm? I am guessing some water ingress, into possibly the siren itself. maybe a sam fault?

Hi,
The 'original' post was for a C320 2000 model (not a 2002 C220 coupe).
There was no W202 320, did they do a 320 W203 apart from C32 AMG? or maybe he has got his 3 and 2 the wrong way round this case it still could be a W202.
If you don,t know what model you have the first three digits of you chassis number will tell you.
If you post the first 6 digits of your chassis number as this is what most people would need to try and diagnose your fault.

I know the original post was not the same model as my own. If you look, it was posted back at the start of last year. I found the post following a "Search" when my car developed the same problem.
2002 C220 cdi Coupe WDB203
Doesn't do it every time but I now have to check each time I lock the car that the flashers have gone out, as they should.

I did not see this post, but I also think that it could be a water problem, this could also explain why it has gone away

 

[jimlee]

Still have this problem and not only in "wet" conditions!
Any new thoughts on the cause???

Alarm corroded slightly...replaced....problem solved

wd 40 the small lock bar on the left behind filler flap you will need to activate and deactivate your alarm to lube.

Hi there. I'm a new member and this is the first post.
I am having an issue with a C220 I have just purchased. It is a 2001 w203.
Sometimes, when I lock the car with the key fob or inner key, the hazard lights flash continuously until car unlocked.
It doesn't happen all the time, sometimes it can go weeks without a problem. The all of a sudden it starts up again.
As the nearest dealer is over three hours drive away, I have to take it to a local mechanic. He has plugged in the diagnostic tool but found no error.
Can anyone help please.

I think that we can say it is the alarm siren that is failing fast
