Honda euro Lux with Sat Nav Purchased 18th Sept now 1740 KMs still has pinging. Back to Dealer twice and no change. Running on 98 OCT Dealer added 2 bottles of octane booster no change. This pinging it would appear is not a petrol problem, yet dealer keeps saying just keep driving it. now metallic pinging will cause engine damage if left unchecked .( owners manual Page 334). So why hav'nt Honda Australia taken action to advise they are doing something about it. Shouldnt we all write a letter to honda Australia direct to add pressure to this issue. There is a contact page on the www.honda.com.au web site. If you have this problem then please communicate it to honda direct. Unless you do Honda will continue to fend us off through their dealers without an official response. Go to http://www.honda.com.au/wps/wcm/conn...es/Contact+Us/
