Dear All,
I recently bot a used 06 525i and recently the ride produces a very loud "Wong" sound when the engine is idling from a cold-start.
Have taken it to my workshop and they can't detect any electrical or mechanical faults.
The sound goes away after about 4 mins of driving or idling.
Anyone experienced the same issues?
Would appreciate any kind advice.
