I posted an earlier thread about the problems with my aftermarket HID kit for my 2002 BMW 325i.

Initailly the auto electrician told me that due to pulsating current in BMW's the low beam HID's flicker (strobe effect). He was going to get a through connection directly from the battery to bypass that issue. The problem just got worse...!! and its costing me $90/ hour (that he is charging) to keep coming up with new faults..!!

He now says that he will have to buy 2 new relays at a cost of $400 (custom made) to by-pass the bmw circuitory and then add 3-4 hours worth of work so that the problem of pulsating current (bmw testing all the electrical components and the lights at ignition stage).

Another temporary solution he suggested is to always turn my headlights on before starting the engine and then turn them off during the day after the engine has started. This apparently he says will solve the problem.... (after $400 in labour cost) .

Is that normal....?? Does anyone of you with an E46 put in aftermarket HID's...? The labour charges are outrageous and I am back at square one after having spent over $400..!!

What should I do.. any recommendations..???

Previous post -
I just bought a HID kit from ebay for my 2022 model 325i and took it to an auto electrician to get them fitted. After install, as soon as the car is started the lights starts flickering and then turn themselves off , however they work fine if the car engine isnt started. The electrician reckons that the bmw has the pulsating current for its headlight and it would need a direct connection from the battery for the lights (which means additional playing up with the circuitory and b,w warning being void). He also adjusted the wiring and globes for the new HID globes, meaning I cant have my old lights back..!!!

Has anyone of you encountered the same problem...? Is it true that bmw e46 has pulsating current for its (low beam) lights..?

Please help..!!

Many thanks,

Is it happening on both sides? if so then the fault might in the installation process. If the kit is under warranty you might want to have the replaced and have another installer do the job, good luck.
