This is on a 2008 535i.

Got the lovely engine malfunction light, went away after engine restart. Even with the warning light on car didn't drive any different, even though I didn't go WOT or redline the engine

Used Carly to pull codes and got 0030FC, which I cannot find anywhere on Google, it seems most people have 0030FF, not sure if they're different?

The error description is "boost pressure control boost pressure too low leak"

Faulty turbos, vacuum leak, fuel pump?

Car honestly drives fine I don't feel any difference; boost still comes on quick and strong, though I'm not driving the crap out of it since the error code popped up

Anybody have this same error code before?

Haven't seen that code before but boost pressure low would indicate a vacuum leak to me

Yeah for sure, just odd because most of my turbo cars drive like poop with a vacuum leak, they would stall coming to a stop, idle weird, turbo would spool slowly, etc.; so far my 535 still feels very torquey down low and mid-range torque still hits pretty good...

I think I'm just going to wipe the code and see if it comes on again

vaccum leak as was mentioned or leak on the pressure side.

possible intercooler connections, charge pipe, etc

I've cleared the fault code and after a few days it hasn't come on again. The night that the error code was triggered it was cold and lightly raining, and it's been warmer these past few days, and I think heat usually brings out more issues for turbocharged cars, so I will keep a close eye on the car to see if anything else goes haywire. The car still drives solid with strong off the line acceleration so far.
