Tach question - RPM bar

WS6FirebirdTA002010-08-18 00:05:05 +0000 #1
I thought the bar around the tach was suppose to move? As the car was cold the warning would move to a lower RPM. At least this is what I have seen on an M5. I have an '07 335 and did not see it move at all. Is this something that may not be active or?

Totally new to all this and tried to search but could not find any relevant posts.

The only "bar" that moves on 335s is on the speedo when you turn on the cruise control - there is nothing for the tach. In 328s and 325s (unsure about 330s) there is an instantaneous "mpg" gauge rather than the temperature one

Mine has never moved. Maybe that is exclusive to M cars.

Gotcha. I saw it on there and it looked like it could move. Guess it is something not active? Oh well lol thought it was cool on the M5, makes you think about getting on it before you actually do

You don't have a temperature gauge?

My car takes a long time to get to normal operating temp (when the temp needle finally stops climbing). And yet I'll be driving for like ten minutes and it still isn't fully 'warmed up'. It's annoying, because I want to know it's ok on the internals, but to wait until the needle stops moving before I go full throttle or even pull to 5K or something, I'm halfway to my destination already. On short trips, it never gets to temp. I really wish we had the moving gauge thing on the 335....

nope, 2010 e90 335d. Our engine runs HOTTT real hot. i'd like to have a temp gauge.

Weird - don't know why diesels wouldn't get one? How hot do you run?

VERY HOT! lol its the hottest engine i've ever had. its weird because the diesel doesnt warm up by idling. whenever you start it up, it always idles at 600 rpm.

Coupes, NA or turbo, have the temp gauge.

Good to know - only coupes I've driven were 335s
