Question for anyone with this experience... I put a InJen cold air intake on my 08 535i LCI back in Feb. Ok, I know, there is no actual hp increase and more than likely a reduction at slow speeds and when the car has is hot and sat a bit. Now to the problem. Twice now I have received the 1/2 engine power light along with power reduction. It feels exactly like the turbos stopped working. This will last for 150 miles or so and when I stop for fuel and then depart, as soon as I get back on the interstate it comes back on again. I was actually on a trip both times... I stopped at the auto parts store but after you turn off the eng and restart the code goes away. When they they plugged into the OBD, there were no codes. A few months ago was the first time it occurred and the dealer said they replaced something to due with vacuum and then I put the injen back on and now it did it again. So I have another appointment at the dealer tomorrow. Has anyone else had this issue with injen? I'm not 100% sure its connected but I'm starting to think it might be... I'll be buying the RPI in the next days anyway.

Have you tried just leaving the intake off and seeing if the error comes back up? Also did you ever get that error before you put the intake in? If not it might be the intake.

your engine is throwing codes due to the increased heat soak and temp. So the engine cuts itself off rather than overheating your turbos/engine. Both members dbae1978 and JohnPhotography ran DCI set ups on their 535i's and both experienced limp modes due to them. Try scanning your car with a Bavarian tech tool rather than an OBD, you might find codes that way, hopefully there are none, as that might void any warranty work needed. But perhaps from your model year, you might have pre-tuner detection software (version 29.2 or lower). IIRC: it's pre 3/2008 build dates have pre tuner detection, but if you're 535i has had any SW updates since, you for sure have turner detection. Regardless if you are pre 29.2, it would be a good idea to invest or have a BT scanner available so you can delete codes as needed

for a scan tool I'd suggest:
http://burgertuning....ol_for_BMW.html
or
http://www.burgertun...om/scanner.html
regarding manipulation codes: for peace of mind sake, I would suggest purchasing or finding some with a scan tool to check for and delete tuner/manipulation codes as needed, especially since you already have a JB4. Try looking for a member local to you with one on here, e90posts, or even n54tuning.com
Since your stock air box is back on and you haven't gotten any codes/limp modes, I wouldn't rush to the dealer, unless you are still getting limp modes with the stock air box on. If that's the case, remove your jb4 and scan your car before going in for service.
