Is the 306 2 litre engine known for pinging at low rpm(below 3000rpm). I'm not sure if it still pings above 3000 because theres too much noise thanks the the air filter. I haven't had the car for long so i can't tell if this is normal. There is only 32000 kms on the clock and it did just have its 30000k service (so the previous owner says). Should i take the car to the peugeot dealer? And of course i'm using PULP.
