My check engine light came on so I ran a diagnostic on it and got these codes: p1225, p1226, p1227, p1228, p1451, p1421, p1425, p1472, p0102, p0135, p0141, p0134. Have any ideas on where to start??

check yahoo for code list and then dig from there start from begining and not just a random code
air in is first exhaust is last
work from begining to end

check each code put them in order then follow each code checking the source

Check Engine Light on - codes P1423 P1421

I'm not sure where you got the codes... I have a Peake R5/FCX-3 - nice for diagnostics.

You should look at the various BMW forums out there - bimmerforums is a good one.

From a simple google search - Google is your friend...

I reset the CEL and it returned with just the P1421 and P1423 code. I researched the web and found that on the BMW, this is the secondary air pump for cylinders 1-3 that provides air to the exhaust during warm up. According to others, this may be due to a check valve stuck open or closed. Or, it could also be a leak in the output hose or a vacuum hose to the valves. The vacuum line runs close to the engine causing it to get brittle and crack. This 30 cents hose can cause the valve to stay closed, keeping water in the pump and eventually, corrosion to occur. I'll work on it over the weekend and post my results.

and

Low vacuum to the check valve. Found the Electric Valve Switch leaking vacuum. PN 11-74-7-537-612 $43.55.
