There's no "both front". If just one bank then maybe not vac leak. If both then still maybe not vac, could be maf needs crc cleaner. Also check fuel trims real time, see if lean at say 3k rpm, if so then maybe not vac but fuel flow.
Follow up. Sounds like my 525i... has a vacuum leak. At least that's where I will start. I hope cleaning it will be good enough as they are $250, and frankly I would rather just pay my kids rent. Mike, regarding your cars look, I think the red rims look great and especially when seen from the rear and you get some taillight in the photo. Anyway I will Google cleaning a MAF and get to work on it. Wish me luck, cuz lean or not... it''s just purring.

Any progress on this im about to replace my MAF but can't find any part number printed on it.
I dont think i have an airleak because i hear no noise when i take the oilcap of on idling or when i remove the dipstick.
Whats strange is that there is no difference in idle when disconnecting the MAF.
I will order a new one as soon as i can find a part number printed on it, its not printed on the top.
