2008 BMW 328I: misfire or rough idle

Filed Sep 27, 2024 · Engine · MI

My vehicle was not included in BMW Recall "23V‑707: Replace Vanos Adjustment Unit Screw Connection" but has suffered the same failure described in this recall. My VANOS adjustment unit screws came loose and caused my engine to completely stall in the middle of traffic on a very busy road [XXX] ). I lost some braking ability and narrowly avoided a major collision. I've been having issues with misfires related to my VANOS system and today I found that despite being told my vehicle wasn't affected by the recall, it is experiencing the same issue as the recall above mentioned. My vanos adjustment unit bolts on both exhaust and intake sides of the engine were all much more loose than factory specification, so much so that I was able to remove 6 of them with my fingers alone. I think there should be a full safety recall on this issue as it seems to affect a much wider variety of cars than initially thought. I was able to re-tighten them to factory specs, but I have no confidence that it will stay that way. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On all e90 series 3 (2008 bmw 328i), the pcv valve fails and is welded into the valve cover, thus if it leaks or gets cracks in the orange membrane, it will cause car to stall.. I almost crashed 2x and this part should be recalled..it affects the fuel air ratio in bmw e90, and the car will run lean and not receive enough gas as air is leaking from the broken membrane in the pvc valve. Bmw will throw engine codes with lit check engine light on dash. This should be a recall as the whole valve cover has to be replaced to replace a defective $10 pcv valve which is ludicrous...the dealer charges thousand dollars and up to replace a ten dollar part. The car has rough idle and will stall, creating a dangerous driving situation and fatal accident . Please recall to have bmw dealer fix these plastic pvc valves on e90s...I have enclosed pic of the valve ..it also has a spring but the plastic orange mebrane cracks, breaks and leaks air inside valve, causing check engine codes, rough idle and stalling of vehicle.. The valve is located on top of valve cover, welded into valve cover. Please help..thank you state florida p.s. Heat causes the pcv membrane to crack more~~pic enclosed of pcv valve its welded into top valve cover..no other car has a pcv valve mounted this way so whole valve cover needs to be replaced~ thank u

I took my 2008 bmw 328i 51k miles to the dealership for a rough idle/vibration problem when car is stopped with brake applied. I was told that the vehicle is unsafe to drive and has two broken motor mount bolts on the right passenger side of vehicle. These broken bolts caused the engine to drop which caused addition damage to engine. I am the original owner and sole driver of this vehicle and it has never been in an accident or experienced any hazardous road conditions. I googled "bmw broken motor mount bolt" and found dozens of forums and complaints about the same issue happening to 2008, 2007 and other model year. These complaints were from 328xi and I owners as well as many other model numbers around the 2008 model year. I read that bmw is the only auto maker that uses aluminum rather than steel bolts and could not find any recall information about this issue. The complaints I read mentioned that bmw of north america did nothing about this issue. I will be contacting them once the repairs on my car are complete. I believe this is a serious safety issue and something needs to be done before someone is injured or killed.
