I didn't see your post until this morning but I have included the post that I just sent to Rennlist. I am wondering now if I have water in the booster that is freezing in the cold temps. If so, can I drain it and save the booster? Or has the damage been done? I had vacuum at the booster but the temps had warmed a great deal. I will keep trouble shooting.

Thanks!

Here is the post:

Thank you everyone for the input...but the plot thickens. So, I was short on time this weekend and only got to spend a few minutes with the car. I read and cleared the codes, inspected the booster and lines/hoses that everyone mentioned. Didn't see anything totally out of the norm so I fired it up and the the check engine light did not register the codes once cleared. I pressed the brake pedal and the brakes were back to normal. One thing to note, the temperatures were in the 40s. Could the warm temps be masking the vacuum leak? I assume that the hoses become more flexible when warm and could that possibly be enough to prevent the vacuum leak from occurring?

I must add I spent 4 years in Stuttgart when I was younger and I do recall some very cold days...do I now own a warm weather only car?

My best guess is that the booster is still functioning and I have a vacuum leak. Thoughts?

Thanks,
Keith
