Okay I have a 2000 328i with 50,000 miles on it. I now am the proud owner of an error code P1624 (Pedal Position switch for electric throttle). What the he## is this I can't even find the part online. Anyone have any idea? Thanks in advance.
This would not be a problem but I have to register car in the next 2 weeks and they hook up to OBD to see if car is running within specs, although car seems to run okay.

That code will come up for cars with a m54 engine; on m52 cars (which yours is), the code readout should be "coolant temp below thermostat regulating temp" (that is if the scanner recognizes which engine is which, which not all will) which means your thermostat is stuck open. Replace your thermostat and have your codes cleared.
Torque,
Ya know I have had a problem with uneven heat in car since I have bought it. Your diagnosis of the thermostat sounds like a winner. I do not think it is pedal position switch - no degradation of performance. Now for the big question is there a website out there that has some tips to complete this task?
Thanks in advance.

Having a hard time finding a e46 specific DIY at the moment, but this should be fairly good instructions; it's for a e36, but same engine, so same procedure. BMW E36 Thermostat Removal And Coolant Flush
edit: By all means keep us updated as far as the results.
Well I got into car after work and low and behold the check engine light went out. Which goes with what Torque has said it is the thermostat stuck open it has freed itself and light goes out. I have ordered new part and will replace as so as light comes on again.
It is off to the state emission control place while light is out -
Well I warmed up the garage and got into fixing the thermostat housing. Pretty stright forward the big problem was getting the fan off. So I installed new thermostat and check engine light went of after about 10 times starting and stopping engine. Jim in Seattle

Glad you got it sorted.......that fan is a PITA without that pulley holding tool!
I have the round type connection under hood and the rectangle type under car dash which is the best OBD to get - knowing when I go to auto zone the code 1624 came up pedal position switch when it was really the theromostat code.
