Hello forum.
I own a 1997 W210 E320 with the V6 engine.
Engine only has 80k miles & seems to run very nicely, but there's one thing that concerns me a bit.
Sometimes, under acceleration or when going uphill (so that I'm pushing firmly on the throttle) I hear a faint but noticeable fast ticking/tinkling noise. The harder I push on the throttle, the more noticeable the noise is. And yet it only happens occasionally - it's hard to reproduce.
At first I thought it might be pinking - it's a similar sound, although what doesn't add up is that it sounds like it's coming from the footwell (or behind the footwell) rather than from the main engine block. And do modern (if 1997 can be called modern!) cars suffer from pinking anyway?
Also the sound is very regular - a fast, regular rhythm - whereas pinking (as I know it from the knackered old Fiat that I drove in the late 80s) was a more irregular, erratic sound.
Grateful for any suggestions. Maybe it's normal. There are no other signs of trouble with the engine - it revs smoothly, has plenty of power, doesn't misfire, etc.
Thanks.
Alan.
