Hi,

Firstly, sorry for cross posting from the electronics subforun - hoping it might get a few views here...

My 2013 E63 has developed a fault with its lighting system. The dash us showing two errors 'Intelligent lighting system inoperative' and 'front left turn indicator inoperative'. It also shows 'adaptive high beam unavailable'.

Sure enough the front nearside indicator in the headlamp unit is inoperative and the relay ticks rapidly when the turn signal is engaged.

Obviously there is a fault, but I'm driving the car to France tomorrow..is there anything I can do? Check fuses, remove and reseat connectors?. Could it be the lighting controller for the nearside has gone?. I'd be really grateful for any testing or diagnosis tips.

Also, If ILS features are not available, will I be dazzling other drivers?.

Help!!

Alex
 
Now resolved.... both intelligent light controllers and the headlamp had to be replaced. Headlamp unit is almost £1000, light controllers are £180 & £270, labout to strip and refit £300. Cause was diagnosed as water ingress due to a defective gasket/seal on the lighting controller, leading to corrosion and a gel pack failure in the headlamp causing to a build up of condensation.

I'm certainly glad it's covered by my Merc used warranty, although the claim was originally denied as headlamps are apparently not covered??
 
Thanks for the update and glad to hear it's been sorted without emptying your wallet!
