I have '87 E30 with M10 engine, and I am in a process of fitting a/c
from a wrecked car. It's time to fit a/c compressor now (everything
else is finished :-)
My first question is: does the compressor have to be at predefined

No noise, just a low frequency vibration through the body..
Noticed it a few days ago at about 70mph. Now noticeable at 50-60mph.
Would I be correct in assuming it could indicate the guibo or rubber u/j on

I have a 1990 525i,  The low coolant light comes on (has been doing
this forever, I think it is the sensor), but recently the low engine
oil light comes on after you turn the car off.  I checked the engine
oil and it is at least 1/2 way up the dipstick.  I looked in the

I'd be grateful if anyone could shed some light on the likely cause of this
fault.
I've had my car (a 1992 320i coupe) for 6 years and it's never let me
down.... until the other day. All of a sudden the temperature needle shot

How common is the 320d turbo failure? I have a 2001 and am a little
concerned its eventually going to cost me a bob or two, Is it

an official listing for the BMW E60 retrofitment kit for Navigation.
Looked fairly complex. Also listed at $4000!
Can this be the real way to update my E60 2006 (530i) to add NAV?  Has

Hey guys,
I'm about to buy a '97 Z3 that's clocked 66,000 miles for US$ 10,000.
Money is basically the limiting criterion on a newer model or a Z4.
Any major issues or general impressions on the Z3 now would be most

Hey all I am new to the BMW world and I have a 20002 325i that has
