[QUOTE="SROK, post: 17198, member: 15645"] Anyone experienced any symptom (besides the obvious sound) and can an OBD check confirm that the engine is pinging?I have discussed with many a workshop and some said that obvious causes is due to the knock sensors, faulty O2 sensors... surprisingly some even told me that instead of being a pinging problem it could be the vanos (but is that not a whining noise rather than like ratling coins??)
