I'm looking for some info regarding ongoing trouble with my 1998 automatic 306 sedan. I've read with interest the earlier discussion regarding engine pinging, as this is the major problem I've had - the car has been back to the dealer a couple of times under warranty, but they cannot locate any problems when running the usual engine diagnostic tests, and initially tried telling me it's dodgy fuel. The problem I have with that explanation is that I have bought petrol from different stations and different companies, including the Shell Optimax, to no avail, and the problem seems to be worsening.
On the bright side, the dealer has been pretty good, to the extent of asking Peugeot in France for ideas, and they have come back with the solution of replacing the head gasket in order to change the compression ratio (this fix was actually also suggested to me by a helpful RACQ technician). I have the car booked in to have this done, and was wondering if anyone else has heard of this fix, and what the outcome of it is? I'm prepared to give it a go, and just hope that it doesn't result in decreased performance or further problems down the track... I'm also wondering if there would be any connection between the pinging and the rough idling of the vehicle - I have noticed when sitting at lights, etc, esp in neutral, that the engine doesn't idle smoothly. All suggestions gratefully received!
