Both of my blinkers in the front won’t work at times and sometimes only one will work, but the side and back blinkers still do. My headlights both will turn on and off whenever they want. When I turn them off and back on from my LCM one of them will usually go out within 30 seconds and a little...

I have a 2001 330ci with harman kardon speakers and the subs and amp is one piece attached to the top of the trunk. A while ago my subs went out and I did some research and found that from all the rattling the coil could be broken so I took the amp apart and the coil looks fine, its connected...

I have a 2001 330ci that I've recently been having issues with. I replaced the fuel filter about a month ago, since I was getting engine lights about low intake. That fixed the issue of that. But, im not sure what the heck is going on. I've been researching for a bit but everyone has 30...

I have a 2001 BMW 330CI that honestly runs amazing. I put a new fuel filter in and its been running really smooth but it has been stalling while in idle. Its happened before a couple times but it was very rare. It just didnt like idling and I really didnt think about it, since I thought maybe it...

Ok, I've tried my hardest to find info online and solve this problem myself, but I can't seem to get it. I hope you will be willing to read all of this and help me because I just CANNOT find the root cause. Just to put it into perspective, I'm a Mechanical Engineer working in the auto...

My car (2001 330ci) has been acting up occasionally for the past several months. It will basically go into (what I think is) limp mode. It just doesn't have nearly as much power, almost like not all the cylinders are firing although it still runs smooth. The service engine light came on about...

Everywhere I look, there are barely any led taillights for my 01 330 vert. All of them, or at least the majority are for the sedans and coupes. Does anyone know if there are any good sets for my car?

I drive a 2001 BMW 330Ci, and for some reason whenever I try to put the top up or down with my key it does not seem to respond. When I put the key in the actual door, and turn it the top does go up and down. I was wondering if this is a code error? I went to the BMW dealership and they wanted to...

I have a 2001 BMW 330Ci, and I installed a Borla Catback exhaust on it. The exhaust sounds nice, after the car has been running for a while, but I am looking to get it louder. I do not want to put headers, as I do live in Cali and smog test will be a pain. any suggestions??

So I keep hearing from people that they have headers on their car, and that if you have an aftermarket exhaust system on your car it will yield some nice performance results. What exactly are headers, and are they illegal, as I do remember my mechanic telling me that they are illegal. I would...

Hello I own a 2001 BMW 330Ci, and I was looking on the Dinan website at their cold air intake, which goes with this model. I was also looking at the K&N 57-1001 CAI which goes with my car. I did some research and people have been saying that the K&N CAI is no good, and will actually make me lose...
