Have a compression test done on the engine. The noise as you describe relates to detonation but being a diesel this is not possible but it could be piston slap (worn pistons /bore) or broken rings that is occurring when the fuel is excessive to allow the engine to accelerate. Check the condition of the sump oil . It should be black but very runny. It is black but very thick you may have a worn motor

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

If I understand you correctly, you feel a vibration it the brake pedal when you apply the brakes. Is that correct?
Have your brake rotors re surfaced; they are warped.

SOURCE: When first driving, I hear a high pitched

I have the exact same problem, however reversed. My whistling sound stops when I accelerate and starts when my foot is off the accelerator. Frustrates me and am afraid to have it looked at for fear of the cost of fixing this problem. Have you since discovered what the problem is or was?

Peugeot 4007, 2011 2.2 diesel. Have fault code P2128. Engine missing when accelerator just beginning to be depressed. Any clues if the two are related?


your fault code is for Accelerator pedal position sensor/switch E high input. Your vehicle has a drive by wire throttle setup which means there is a wiring loom instead of a cable from the pedal to the engine and the pedal sensor is there to provide the engine ecu with the info of how much acceleration the driver is applying with his foot

Loud ticking/knocking/rattling sound when I start/accelerate


hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456
