This is the tick of my 325i N53 engine.
Is this normal guys? I don't recall any tick when I test-drove the car prior to buying it (recently). I found out recently that the engine was missing the stem that holds the oil filter (oil change) so I've replaced the oil filter cap with stem now. Seems softer than before but still strange.
Anyone that might have a clue? I have an intermittent 30C1 error but otherwise, nothing else
