I'm looking for a free 2000 bmw 3 series repair manual 328i sedan, crankcase vent valve installation

There are lot of videos in this link. Opening and closing an electric or hydraulic hardtop is always going to be difficult because they are so heavy. I had a friend with and Xi5 and he had the soft top / hard top option and he had pulleys and a winch to lower the hardtop because it was only just manageable for 2 people to lift.

The best plan is to get it fixed for automatic operation.

That is a code for the electronically controlled engine thermostat. Have checked asap before you do very expensive damage to your engine.

idle control valve.

Your sensor is going bad or you have to change your oil.

I have 1998 BMW 328i and it shut off entire air condition system while running. sometime it works fine then suddenly it shut off while driving.

There's nothing special from BMW it will be one of the airtake valves not shut properly, or stuck in open position. Follow the hot air and try to access the source to identify the actual problem

If you'll need something more detai, just drop me a line

Good luck
