R172 HID Xenon Conversion - Anyone had success ?
I have done this conversion on two Subaru's and a Mazda,with no difficulty.
They had Canbus.
I have just tried an install on my 2012 SLK350 and had to revert back to the H7's.
Initially both HID's worked OK and the improvement is huge, as it always is.
After about a 20mins drive the first one turned off. I stopped and restarted and then neither would come on.
The status display informs me RH and LH Dip Beam are out.
So back in the garage I checked out the two units in situ, with DC from a seperate battery and they work normally.
I dont understand why it worked at all in the first place.
The web is full of comments on Canbus and how to fix it with a 4700uF Capacitor (I tried it and it made no difference).
What I could not find is any technical discussion on how the lamps are monitored, and how Canbus turns them off. Given the H7s draw about 4.5A and the HID is 4.3A it should not see any problem. The peak current at turn on is higher at about 7A for the HID.
Does anyone understand this well enough to explain what is happening ?
I assume someone has managed a successful install - if so what kit did you use ?
