new xenon lights from slk55 installed on slk350 don't work properly

I swapped regular headlights with the Xenon headlights in slk350. When I turn the lights on (engine not running), they work perfectly. As soon as I start the engine they start to blink, flick like strobe lights. Any body knows what is going on.

I heard about this problem before. I think the dealer has to set something.

My suggestion is to post in the R171 SLK-Class forum. They could help you there.

Oh, and Welcome to Benzworld![:)]

The xenon lamps don't draw as much current as a halogen bulb AFTER they start and are setting a fault because they appear to the cars electronics as defective bulbs. Also do not attempt to use the DRL feature because the system still thinks you have halogens and attemps to run your lights with reduced voltages which will in time over heat and damage your HID ballasts.

You need to have the dealer reprogram the electronics with STAR to tell the system you have HID lamps installed. That will also allow the DRL's to run at full power like they are supposed to.

Thank you for going the correct but expensive route to get the HID's added. There is no legal way to put HID lamps in a halogen fixture because the beam pattern for halogens is way different from what is needed for HID, making it impossible to aim it in a way that will keep it from producing illegal amounts of glare.

For the prices any MB sells for in this country HID should be standard equipment. Its standard on all 06 VW GTi's and they start at less than $22k and come with most of the same electronic toys found in the MB except that they don't fail as much. Maybe DC's purchase of a large chunk of VAG will give them access to the some of the same sources of parts VAG uses.

Potato Chip, custom canuter valve, low-friction muffler bearings, synthetic turn signal fluid, Hi-Definition Progressive Scan Wiper Blades.
Law-makers are supposed to regulate in the interest of the public as opposed to regulating in the interest of the regulated party.
If it says Pratt and Whitney on the outside it better say Martin Baker on the inside.
