I'm in a market looking for a 97 - 99 540 and I am just wondering what should I be looking out for? What are some of the problems with Manual or Auto transmition?

read the thread below this.

but generally these problems would come up.

MAFs
radiator, coolant return pipe, water pump, t-stat, expansion tank (pratically the whole cooling system)
O2 sensors
broken cup holders
missing pixels on the LCDs
vanos sensors (after 98 only, and very few people had problems with it)
automatic transmissions needs software updates

for others:

but then again, its a pretty reliable and durable car as long you replace those things on time.

How often and where do you get these updates?

dealer, there's only one update so far, for 99-2003 autos.

will the tranny act up in any way or is it just something you go and do?
