Jazz Pinging

[yakuza]

I finally managed to take my pinging Jazz to the dealership on a hot day. And they confirmed the pinging. Howver they could not put it down to any particular reason. They have asked me to run some PULP ( from MObil) and straight away the pinging stopped.
I am not sure now what the next step will be. Will call the dealership tomorrow.
I don't want to use PULP all the time as the reason i bought the JAzz was fuel consumption with Regular unleaded.
I will keep you posted

Hey mate:

You hear anything from the dealer yet? I have similar issue with my wife's Jazz, but no time to bring it back to the offical dealer, but I am pertty sure they can't (or won't) do anything anyway.
I try to fill PULP the other day, pinging seems gone, but still can hear couple of times and getting less and less. I bet the computer needs to adjust time by time and finally all disappear, therefore the pinging getting less & less. I applied this rule from subaru's car which known it from my friend (he is subaru mechanic).
What do you think? true or not?
