Hi fitted a hid kit today it went well apart from my passengers side turned off,so i turn lights off then on again and it came back to life,after about 5mins it done the same thing,so put back to standard.Has anyone else had probs with hid?i would like to get this sorted as they looked good.

Did you try swapping the ballasts to see if you then had the issue on the drivers side?

You may need the canbus error free type. Does it say that anywhere on the kit. If it does then go back and check all your connections.

no just took them out.spoke to my m8 who has had a few hid kits on cars and he thinks its the bulb?

My bet is its either (in order of likelihood) : a faulty ballast, incorrect kit type (you need, but don't have, a canbus error free type) or a problem with the wiring (e.g. thin wire so inadequate voltage at the ballast input, or a poor ground).

I'm also betting its not the bulb.

Most likely cause is not getting enough power. AAM provides PWM voltage but the ballast needs constant 12v with high amp to fire up the bulb. You should install a relay if you haven't done so. This will provide power directly from the battery. Relay will also protect the AAM in case of a possible short circuit. If the relay causes a flicker or chatter, install a capacitor. Other reasons would be wiring, ballast or bulb.

No mention of canbus error free, so the kit type may be the cause of the problem.

If you try the left ballast with the right wiring and/or the right ballast with the left wiring and the problem changes sides then you know you have a faulty ballast.

If the problem doesn't change sides then the problem is canbus error (change the kit or get an error cancelling harness) or wiring (check for adequate power supply and good grounds, or install a relay harness as per the above member's post.

I'm still betting it's not the bulb .... if it works for 5 or more minutes each time then the bulb should be good.

I went with this kit in my 98 ML320, and haven't had a single issue. It was plug and play without the need for any extras.

I think you could be right about it not mentioning canbus.will get another kit

 

[mattml430]

You can keep your kit and just buy some inline canbus error free kit
you will have to search for one that suits H7 globes. Be aware the resistors get extremely hot and need to be attached to steel not plastic.

I been doing some looking around and been hearing ml w163 dont have canbus? is this true or crap?

 

[RedLiner]

Those ultra slim ballast units are very unreliable!
I bought the same or similar kit from eBay UK and both ballasts went faulty in just a couple of months.
The seller was very good and sent two more ballast units which were beefier and reliable. I fitted a HID kit to my my older SL500 the ballast units in that kit were full size and have never let me down in just over 5 years.

 

[mattml430]

I thought being a 03 it might of had it or something similar that recognises the different current draw to your lights which will require the canbus type ballasts.

I managed to send the kit back and have ordered this one

kit turned up today ballast have a nice bit of weight to them also ordered a relay kit.will try and fit tomorrow with a update.

My ballasts are on the big side to, but I was able to mount them right under the headlights with room to spare. I just passed my first NY State inspection today, since installing the kit. I was a little worried about that, but it worked out.

Here's mine here:

You could probably do the same.

just read this thread and it looks like 2003+need error eliminators.

I fitted the hid kit today and works well,the only problem is if you use the auto lights it puts the esp light on when starting the car at night.I did not need a relay and have no flickering.

Well done, after a possible faulty ballast, wrong kit was my next guess. Very strange that the ESP light should come on (presumabkly it goes off after the car has started) .... maybe one of the experts here will have a theory on this as the linkage is not obvious to me. My guess is its probably electrical interference or back EMF or similar (or Canbus related) so not something easily overcome .... you may have to live with it.
