Flashing sidelights, is this normal with LED types?

[DSM10000]

I have noticed that if I put the key into the ignition switch and do not turn it then after approximatley 15 seconds the dashboard lights and sidelights flicker. if I turn the key to any other position this does not happen.

I am not sure if it is relevant but the sidelights are LED replacements( kindly supplied by a forum member) and are otherwise working as thye should

I just checked, and my C180K 2006 does not do that... all that happens if I plug-in the keyfob but don't turn it is that after a while the display on the instrument cluster goes out. No flickering lights and no drama... hope this helps.

I get the same result as markjay and I too have LED sidelights (and no. plate lights) fitted and have had no issues whatsoever. Sorry if this isn't what you wanted to hear...

Update:

It only does it if it is daylight and the doors are closed!!

Well, that's how I tried it on mine, so it still shouldn't be happening?

I suppose the next step is to go back to the original non LED bulbs and see if it happens. Not sure why the circuit is energised with the key in the igniiton but not turned. The lights are currently turned to automatic.

My BMW does that. It's the bulb fail system checking for bad bulbs. My irritating LED sidelight bulbs flicker but the incandescent bulbs don't react quickly enough for it to be visible

Thank you, I had just come to the conclusion that it was probably the bulb checking system.

OK, if it only affects the car when the key is in the ignition and not turned... why not just live with it? Can't be that bad...

I had intended to do just that, I merely wished to know if anyone thought it may be indicative of a fault elsewhere.
