Two different problem codes, 2A87 "Outlet-Vanos variable cam control test" and "2A82 Inlet-Vanos variable cam control test", are thrown indicating the possibility of various VANOS-related problems. E90, E91 and E92 (3 Series) with N52KP and N54 engines from 7/2006 production E85 and E84 (Z4) with N52 from 1/2006 production E83 (X3) with N52 ...
If you drive a BMW, then you’re one of the luckiest drivers in the world; these cars have remained some of the highest rated automobiles for decades, and they continue to surprise drivers with their innovative engineering and design solutions. One such engineering concept coined by BMW is the VANOS engine, which includes what’s called … Continue reading "How to Detect a Valvetronic ...
So it gets three stars for that. Loses two stars because it cause an erratic idle when cold. The idle surges around between 700-1100 cold. Once the car warms up and has been restarted, it works fine. I’ve verified with another VANOS solenoid, the OEM one works flawlessly regardless of engine temp. 2011 MCS, R56 with N18 engine.
I'm getting both codes 2A7A and 2A7C with check engine light. I've already replaced VANOS solenoids, camshaft position sensors, and cleaned filter/check valves. I've checked voltage to solenoids and relearned actuator limit stops. On cold starts the RPMs rev up to 1500 for a second and back down then there's a rough idle until the car warms up.

These VANOS faults may be caused by insufficient oil pressure supply to the inlet VANOS adjustment unit. To effectively move the camshafts to the target positions in the specified time and under all engine conditions, sufficient oil pressure supply to the VANOS control pistons was required.

The system uses a gear on the Vanos actuator and a gear on the camshaft. A solenoid then controls the amount of oil pressure being applied which controls the movement of the cam gear outward or inward, effectively controlling the timing of the valves.
Got the codes 2A7C - VANOS, inlet, cold start and 2A82 - VANOS, intake, variable cam control test. These are the symptoms. The engine has a loud ticking/rattling noise at 700-1500 rpm. It goes away at 1500 RPM and above.
Then, occasionally, the engine has hot start problems. It cranks, starts, rough idle and then stalled. No problem with cold start and driving and there is no CEL, but when I pull to the car to the dealer, it shows fault code P1030, which means the Valvetronic Eccentric Shaft Motor has a problem.
However for the first time it set a different code. The BMW code 2A7C intake cold start cold went away. Only the 2A7A Exhaust cold start code came back. I also got DTC P054B - Cold Start Exhaust 'B' Camshaft Position Timing Over-Retarded Bank 1.Before I had DTC P052B - Cold Start 'A' Camshaft Position Timing Over-Retarded Bank 1.

In this technical article, we will give you the definitive guide on diagnosing BMW variable-valve timing (VANOS) faults. The procedure will take you through multiple checks, tests and visual inspections to determine what is causing the symptoms and fault codes on the BMW you are working on.
I have just put my R56 1.6 Cooper into bmw with Engine Light and they have told me Inlet Vanos Fault 287D Stored. Is this easy to rectify, can I do this myself.
After parking it for about 8 hours went to start it again and BAM! same s*it happens oil pressure too low and half engine light. pulled out the codes and it came up as 2A7C (no description found) and 3100. left the car like that overnight and the next day, i pulled the vanos solenoids, cleaned them and changed the oil and filter hoping it would ...

Aug 13, 2020 · P052B BMW Description To assist with cold start conditions the camshaft timing can be adjusted to allow for optimum starting conditions. This Diagnostic Trouble Code (DTC) will set when the Engine Control Module is unable to control the actuator correctly.
The VANOS faults can be caused by an insufficient oil pressure supply to the inlet VANOS adjustment unit. To effectively move the camshafts to the target positions in the specified time and under all engine conditions, sufficient oil pressure supply to the VANOS control pistons must always be available.

Hi I'm a newbie on this forum and to BMW in general. I recently purchased a 97 528i and started having a rough idle problem on cold starts in the morning. The car will start perfectly and after a couple of seconds it'll start idling rough for about 3-5 min. Since I obviously got the car used...

3. Vanos were replaced buy dealer. they told me the SULEV warranty was on the internals not the sensors themself ? Now got the car back and at start up seems ok . After a minute i can hear something kick on and the engine runs and sounds like a diesel. When i drive at 5mph + the ticking and knocking go away but as soon as i stop it returns ...

The Vanos system uses oil pressure to control the position of the intake and exhaust camshafts. The system uses a gear on the Vanos actuator and a gear on the camshaft. A solenoid then controls the amount of oil pressure being applied which controls the movement of the cam gear outward or inward, effectively controlling the timing of the valves.
