Grumbling noise when engine cold
Just got my new (to me) 2003 Volvo S40. Love it to death, but there is one nagging issue. When you start it in the morning, or when the engine is cold, theres a strange grumbling noise; but only in reverse or drive. It sounds like its forward of the driver's seat, but that could just be because of where I sit in the car. After about 5 minutes of idling the noise is gone regardless of gear. Any ideas?

Loose baffles and exhaust parts often quieten down once the exhaust gets hot and the metal baffling inside expands enough to stop rattling loosely inside.
If it is that you will hear it if your underneath when its running cold at startup.
When you slip her into gear it can get louder too.
Maybe check your exhaust support brackets beneath the car also.
Are your engine / transmission mounts all ok?
The sound Hudini has described is what I get when reversing from garage also.
Mine however, (V40 2002) is not a grumble, just a very subtle whine as is typical of hydraulic systems.
