With the weather turning colder and old plastic getting more brittle, I'm having vacuum trouble with my 300D. It still turns off, but it takes a good 30 seconds after I turn the key off. I thought I fixed it today by changing the little rubber piece that mates the brown/blue line to the shutoff solenoid. No joy. It really doesn't help that the whole system is so old that looking at it is almost enough to trigger a leak. I'm picking up a box of golf tees and some different size hoses tomorrow. At least we have the vacuum diagram sticky

I was considering ranting about what a bad and ultimately doomed idea it was for the DB engineers to run so many things off vacuum, but then it occured to me that the car is 26 years old and that electrical, air, or mechanical solutions would probably not be doing any better at this age.

Rant over

Any tips to make my vacuum life easier?
