Nearside refers to the side of the car nearest the gutter and the other term for the other side of the car is offside.

What happens if your facing the car? Similar to boats where you say port and starboard I suppose it is explicit which side you are talking about.

Martin

So on a left hand drive vehicle,as driven in other countries, it is around the other way?

The nearside becomes the offside and the offside becomes the nearside.

Generally i think the normal way is left and right as you are sitting in the vehicle.Easy.

And this started out about a noise?

Every time I parked my car in the garage I would hear and mentally go through its "song" of high pitched whines and sounds from actuators and egr valve cleaning pulses. It was the same "song" for a couple of years. My darling wife would greet me at the door and one day we both commented on how the "tune" had changed? 2 days later I got the reduced power and "engine systems fault" in the message centre. This forum directed me to make up the bent wire thingo and exercise and lubricate the turbo actuator. It fixed the issue and guess what? - the regular tune has returned on engine shut-down. So I can assume that one off the clunks and whines is the turbo actuator servo motor running through a full cycle as part of the shut down procedure. I'm yet to be proven right, but I will put one bag of clam shells on it!

I asked the OP's question a while back and got told it was all ok. Now rather than worry about the fact that it exists I'm now going to carefully listen to any changes in note or pitch. I will then imagine the worst and fly regularly into a panic.

I must now go an search for the turbo actuator tickling procedure thread.

Driving the Defender all those years without realising it I developed an intimate knowledge to all the noises and vibrations that occurred. I would be rolling along a country road looking at the scenery in what I thought was a revery and then all of a sudden I'd be on high alert "What was that?"

My Puma does this song as well. It's the cars way of saying good night, don't you know?
