Need some advice on the following codes(details within).

So, my daughter is in Florida with my 2005 E46, about 130,xxx miles. The service engine light just came on. I was able to get her to scan the codes and this is what came up.
P1412
P0700
P0710

Any thoughts or advice would be appreciated. Thank you.

I recommend that your daughter take the car to reputable independent (indie) shop that specializes in bimmers. Try www.bimrs.org. The shop needs to have the proprietary BMW software to properly diagnose the problems. The engine computer (DME in BMWspeak) and the automatic transmission computer (EGS) need to be scanned for codes.

The secondary air pump system lives near the exhaust manifold and the system has rubber and plastic parts. They tend to go bad and leak. This is a fairly common problem with higher mileage E46s.
