    Hello peeps, my new to me 57 plate cdti shudders when I start it or turn it off. It is much more noticeable on starting it up. Depressing the clutch makes no difference. I can also feel some vibration/slight tremor when idling and below 1500 revs. Should I be worried or am I being unrealistic as this is my first diesel car? Thanks in advance for your input.

    Car shudders on start up & turn off

    Do you let the glow plug light go out?
    Mine will normally start straight away without waiting, but occasionally it won't.

    Thanks, it's not that, starts all the time whether I wait for the light to go out or not. Just shakes/shudders at start up and turn off.

    Hope not, I'd like to think it's worn engine mounts as I get no other symptoms.

    How many miles have you got on the car, any remaps ?
  7. goonerfromlag Club Member ★ ☆ ☆ ☆ ☆

    62.5k at the moment, no remaps, thanks.

    I cannot see the DMF causing this , just check the acoustic engine cover is held on securely with all the rubber mounts present and correctly in place. Checking for missing washers too. I have seen engine making all sorts of racket when the cover not on securely.

    I would expect a DMF to cause shuddering while driving and changing gear as well, not just on start-up or stopping.

    My first thought was engine mounts too. But 62.5k does possibly seem a little premature for that, but that's personally what l'd start with.

    Thanks guys, will have a look-see, does anyone know of a well recommend indie garage in london/essex/cambridge?

    As this is your first diesel it could just be the difference in engine. If you get a chance why not take a short video clip and upload it. Either that or find another Accord and compare noises :Smile:

    Thougth I'd update this instead of a new thread, my steering wheel pulses back at me when I turn it a quarter way round whilst engine idles. What does this signify? Thanks for your input.

    can't say without looking at it maybe , CV joints?

    Thanks, got it booked for a diagnosis at honda cambridge, wary of them just plugging into an OBD reader and then telling me it's fine becos it's got no error

    Mechanical noises and vibration will not record any DTC on the ECU,any electrical device which talks to the ECU or the multiplexers will log DTC's when a problem is detected.

    Potentially the technician picks up some cure during the VHC (Vehicle Health Check)

    anyone tells you otherwise run :Whistle:

    If it does this whilst not moving, it's just the power steering pump. Mine does this a bit. I think it is due to pressure fluctuations caused by the friction of turning the wheels without moving.

    Thanks guys, I'm awaiting the results of my 'diagnosis' at the moment, apparently the 'vehicle health check' happens evertime a customer's vehicle is looked at.

    Surprisingly the technician didn't find anything wrong that might be the cause of said shudder, though only charged me £12 for the priviledge. Got my fuel filter changed at the same time. I'll be taking it in to Holdcroft Honda this weekend for them to have a look at it.

    I have a slight shudder when starting/ shutting off the engine since .. I can remember. I guess if it was DMF then I'd be seeing it getting a lot worse. Done almost 90k and no change. Unless it's really rough I wouldn't worry about it too much.

    Thanks, thing this is mine isn't slight, particularly first time in the morning.
