Hello All,

I would appreciate help with may current BMW X5 50i issue which is related the following codes. Also I replaced the components listed below attempting to resolve issue.

Symptoms:
Engine malfunction light comes on after idle phase drops from 1200 to 900rpm. Light will sometimes clear when restarting the engine. No rough idle or erratic engine surges. Car runs fine.

Codes read with ISTA D:
2B18 cylinder 3 misfire
2A79 Variable camshaft timing control, intake, cold start
2A78 Camshaft position controller, exhaust, cold start
2A7A Camshaft position controller, exhaust, cold start
2A75 Variable camshaft timing control, intake 2, cold start
2A7D Variable camshaft timing control, intake 2, cold start
2A7C Variable camshaft timing control, intake, cold start
2A7B Variable camshaft timing control, exhaust 2, cold start
2A7E Exhaust VANOS 2, mechanism

Replaced components this past summer:
1. 4 Vanos solenoids (Pierburg)
2. All 8 Spark plugs
3. Ignition coil cylinder 2&3 (Eldor)
4. Both O2 sensors before catalytic converter
5. 2 Mass Airflow sensor
6. Oil and filter change
7. Valve stem seal replacement at Dealer(summer 2019)

Definitely related to cold start issue. Annoying "Engine Malfunction Light".

Thanks very much for any suggestions!

Roger
