I had what I thought was a pinking sound (sound like a ball bearing rattle in a can) on hard acceleration, mainly up hill but only in summer. It started when the temp gauge needle got up to the middle point and stopped as soon as it dropped below.
No Volvo mechanic has been able to tell me what the cause was, I did suggest a fuel/air mix problem but was told that this couldn't happen. A couple of winters ago, the mass air flow sensor failed (£325! - got a used one off ebay for £25). With the replacement, even with slightly low values, the pinking stopped. |
