So my 2003 325xi always seems to act up in the rain or when it’s cold. For example if it rained in the morning or it’s cold and I am getting into my car to go to work when I turn it on it will shake and acts like it wants to turn off. It never stays on long enough for it to warm up and I have to keep turning it off and on until it warms up enough to stay turned on. Also when ever it rains my driver and pssanger side rugs are ALWAYS wet but it seems like it’s coming from underneath ? Help :/

Welcome to the Forum!
What is the condition of your windshield cowl? That can be one place where water intrusion can happen, the other is the sunroof drains are clogged.
Does the check engine or SES light up when it is doing the funky stumble? If so what are the codes?

The first step in diagnosing a problem is to scan the engine computer (DME in BMWspeak) for codes. The service engine soon (SES) light is on only when an emissions related code is present. Go to your local parts store and have someone scan the DME. I’m betting you have a vacuum leak in the intake manifold. But scan the DME first.

The water is more than likely coming in from the doors. The sound insulators (or vapor barriers) are probably not sealed and the water will leak out the bottom of the door panel into the car.
