After doing some research i decided to buy the 2 vanos cylinders and replace them, well after driving for 4 days the code came back now I am thinking if it is because they are after market ones. Plus my inspection is already expire and one of the mechanics told me is not going to pass inspection because of this.

For some extra info 2 years ago I already replace my 2 Timing Camshaft Gears. Could be this problem again ?

Hi, Did you ever get this fixed? I'm having this issue, have ultrasonic cleaned and changed the vanoses, changed the oil, checked the oil filter (which was fine). I also have the 2006 330i.

2007 335i with the N54 engine.

I got the 2A87 + 3100 codes at some point. Around 120.000km/75k miles.

Preceding this I heard the "marbles in a can" noise at idle after a cold start. That noise went away after 30 seconds, sometimes more, sometimes less. But it went away. Very occasionally you'd also hear it when sat at the traffic lights (6AT transmission). If you put it in "N" the noise went away on a WARM engine. This confused me into thinking it's an engine/transmission mount or similar issue.

After another month or so I started hear a strange metallic noise at low RPM, typically around 1500-2000 rpm. It was an electronic-like noise with an increasing pitch. The duration of the noise was around half a second and sometimes as long as 2-3 seconds.

In the end the problem was a dirty VANOS solenoid but also the Ledge Bearing having been worn. Oddly the exhaust solenoid was noticeably dirtier than the intake one.

2006 325i getting same code now. Used to get p0015 "exhaust camshaft position" timing over retarded bank 1. No longer getting that. Now just the 2A87. Will try swapping today. Already cleaned and code cake back. You figure this out?

Shot in the dark, had marbles in a can sound at cold start too expecially on deceleration and 2A87 code, found that the check valves were stuck open, after cleaning them they were totally not moving when shaken like the new ones (like "click click click" sound), and after changing them and the chain tensioner the noise went away, it's been 60k km since then

My issue was fix by buying original parts, the aftermarket ones was the problem

I have replaced both VANOS cylinoids & the Valve cover but my car is now throwing the same codes as urs (2A7A & 2A87) but is driving fine. Does anyone know if the N51 SULEV engines carry the 10yr/unlimited miles warranty for the cam gears?

Did you ever have any luck with this? Having the same problem on my 2011 328i xdrive with N51 SULEV. Supposed to go to dealer to see what they can do. Just got an email from the dealer saying I had a recall for “VANOS bolts” but I asked about it and they say that they can’t do anything because “there is no available remedies” yet….

you can get it fixed at a third party shop, save the receipt, and have bmw refund you when the fix is available.
