Hi im new , great site.Drive a 325i e90 faultb ive got is 2AAC ,any clues?

[Lord Vader]

2AAC stands for Variable Intake System 2. Are you getting any other codes?

[DEON]

NO no other codes.this is what I picked up on my autoboss scanner. I removed vanos solenoids cleaned them and swapped them around. still same code. car seems to have less power on low revs

[Lord Vader]

Other people who reported having that code also got several others including a VANOS code. Most people found it was an issue with the VANOS system. If the VANOS isnt working properly you would notice, as you do now, less power then normal.

Thanks Vader...plan to take it a part this weekend . will feedback my findings.

If you do find an issue with the VANOS system then head over to Beisan Systems. They are the OEM supplier of the VANOS units. I have heard that "Dr. Vanos" is a rip off.
