Mein Auto: 2007 328i
2AAB and 2A13 Fault Codes

Hello everyone! I'm new to this forum and found this site to be very helpful and informative to fellow BMW owners. I have a 2007 328i which the Service Engine Soon light came on a couple of days ago. From reading this forum I knew that it could be a few different things and will not definitely know until I get the fault codes read. I'm out of warranty so I don't really want to spend $125 (as some of you may have mentioned here) just to reset the warning light for a simple fix such as a loose gas cap. Anyway, I purchased the Peake Research Engine Reset Tool to find out what the code is and to reset the light. I received the tool today and plugged it to my car. I received two fault codes: 2A13 and 2AAB. Looking up the definition of the codes, I get the following:

2AA13 - DMTL Diagnosis Module Tank Leakage, leakage diagnosis pump, input signal
2AAB - Variable Suction Unit, Self Diagnosis

I've reset the warning light using the tool but I can't help but wonder exactly what those codes mean and does it mean I'll have to bring it to the dealer to get something replaced or fixed. Btw, before I got the tool I checked the gas cap and it looks fine/not loose (though it was easy to unscrew). Any help will be much appreciated.
