    The better half has a citreon xsara, in the last day or two it is making a funny ticking sound when you take your foot off the accelerator. Any ideas before i bring it to a garage? It sounds like its comming from the front (i.e. engine) its not the exhaust as far as i can make out and not the suspension either, grateful for any ideas.

    I'm assuming you can hear this noise in the cabin with the engine running? Does it happen at higher speeds? Does it only happen when the car is moving? Can you hear anything under the bonnet if someone revs the engine?

    Ticking noises on a stationary car are usually associated with metal expanding or cooling (brakes/manifold/exhaust/cat convertor). Ticking noises on a running car and coming from the engine might be alternator/cooling fan/water pump associated or more extremely due to valve timing or timing belt about to let up - I had a Civic which 'ticked' on the overrun ie when I lifted off the accelerator and I tracked the problem to the camshaft drive wheel having come loose. The ticking was the valves hitting the pistons when the cam timing was delayed.

    Bottom line - more info please for better diagnosis....

    " Does it happen at higher speeds?"

    20MPH+

    Could be a gearbox or driveshaft problem. When you lift off the throttle does it tick for a few seconds and then go away or does it keep ticking until you put your foot back on the throttle.

    Does it tick with the drive to the wheels disengaged or engaged or both? If it ticks while the drive is engaged but not while disengaged then it could well be a transmission problem although it's hard to know.

    Also, does the ticking get worse when turning?
