2882

What the Code Means

2882 logs a VANOS fault on the intake camshaft of cylinder bank 1. The DME compares the target and actual camshaft position and finds a mismatch — the phaser mechanism isn't following the command.

The causes are typical for this system: a stuck VANOS solenoid, clogged oil passages, a worn timing chain, or low oil pressure. In this case the pattern is telling: after cleaning the solenoids and replacing the seals, the code disappeared temporarily but came back. That points to a recurring oil leak past the solenoid seals — the repair fixed the symptom, not the cause.

Symptoms

• Rough idle;
• loss of power;
• increased fuel consumption;
• Check Engine light on;
• metallic knock on engine start.

Diagnosis and Repair

1. Read the fault codes with ISTA or INPA.
2. Check the VANOS solenoids: winding resistance should be in the 7–12 ohm range; also run a click test by applying 12 V to the solenoid.
3. Clean the solenoids and replace the seals (OEM BMW 11367579070). Given that in the case described the code returned after this repair, look for an oil leak past the seals — the likely root cause.
4. Clean the VANOS oil filters on the block.
5. Reset the DME adaptations and take a test drive to see whether the fault returns.

Secondary Damage

• Timing chain jump with valve-to-piston contact — up to a full engine rebuild (the expensive recovery path);
• catalytic converter damage from unburned fuel reaching the exhaust.

Given the likelihood of mechanical damage, don't put off diagnosis: the severity of this code is major.
