Hello, please excuse my ignorance in this area, though l would be very grateful for any advice & opinion.

The Alhambra 1.9tdi has been extremely reliable over the past near four years. Though there is nearly 168, 000 miles on the clock, it has a full service history & runs fine.

However, over the past few months, under conditions of low excelleration, l have noticed what l can best describe as "pinking" a metallic creaking until the car has reached a faster speed.

Is this something that a diesel would do?

Views gratefully sought as to cause & any actions needed.

{'y' changed to 01 as the compulsory fill in box asks for the year, not the registration number!}

No....perhaps piston slap or something else worn, is the sound at half engine speed, less or at engine speed?

Hello & thank you for the response.

the sound is at less engine speed under conditions when there may not be enough revs during excelleration.

The places to start looking would be Camshaft, Timing Chain (if it has one). Also have a look at the oil for any metal particles in case anythings breaking up.

A good look around the engine bay might also turn up something unexpected, so have a good search around for anything that might not look right....then start the car and have a good listen all round under the bonnet.
