Driver Side Window Issue '06 330 CI

I'm hoping this isn't a regulator issue, and a relatively easy fix...

My driver side window has been gapping lately. It still does the 1/4" drop when I open the door. When I shut it, it looks like the first picture attached. It's not always that wide, but most of the time it is when I close the door. When I go over bumps, it sounds like something is trying to push the window up (sometimes if I hit a big enough bump, it will go up on it's own). Is there anything I can do to remedy this besides replacing the regulator? Our local dealer wanted over $1,000 to replace it, and I'm clearly not going to do that. If I have to, I'll just keep rolling down the back window all the way, roll the driver window down partially, and pull in on it when I roll it back up - this has been a temporary fix that has worked for me, it's just really annoying.

It should be noted that when I leave the vehicle, the gap isn't as bad, but it doesn't look like it's hitting the top as it should. The bad gap happens when I am getting in the car and shut the door behind me.

ANY input would be appreciated, thanks!

You can DIY a window regulator in a 2-3 hours. IDK if that's it, but it's probable.

Also it took me a minute to figure out that your car is a convertible. Be specific...

The title clearly said CI, I thought that was enough?

Thanks for your input though - anyone else have any ideas?

FYI: the common convention is that Ci means coupe, CiC means convertible.

The coupe and convertibles are not prone to regulator troubles. Remember on the convertible (same part as the coupe) the windows are designed For cantilevered operation and are very robust.

What you need is an adjustment of the window angle as it slides into the channel. You adjust this in conjunction with the window drop height to properly clear the rain channel.

Search for the DIY guides. You'll see what tools you need and the correct spec for the window adjustment.

Well, technically you are correct; your car is a 330Ci convertable. But, we all add the extra 'C' to denote a 'vert as a handy moniker. BMW never used 330CiC (or 325CiC) as far as I know.
