Clonking / pinging noise from Vario 340 Should I be worried?

Post by baron_matt » 23 Nov 2012 08:44 pm

This evening I notice a slight clonking / pinging noise from the car under deceleration. Almost sounding like a back pop of pinging you'd get on a throttle closed long hill decent in gear.

Now can any guru's out there tell me is this likely to be? Is the mixture too rich giving the old back popping in the exhaust or is there something terminal going on with the Vario system that I should be aware of? ie its a clutch/propshaft type fault?
