Diagnosis table
S01 Engine pinging
The engine gives off a cyclic noise, the intensity of which varies with the load and can be heard during abrupt accelerating and using high gears
If disconnecting the utilities belt the noise ceases, it is coming from a part driven by the belt: see table S10
If the noise only occurs with the car on the move and disappears with the vehicle stationary: see table S40 or table S41
If the noise only occurs when the clutch is engaged, see table S20.
