Hi all,

I have a 2004 Exclusive 1.4HDi 16v with climate and cruise control.

It has developed a problem in that when lifting on or off the throttle above 2000rpm in mainly lower (2nd and 3rd) gears it makes a "thud" noise at the start of the pick-up and overrun.

Any ideas anyone? Your help would be appreciated.....

Many thanks,

Doublehelix.

Hello Doublehelix, if you are getting near the 'magic' 100 000 miles mark, then I suggest the lower engine mount.

Have a look at diesel-citroen-c3/2002-c3-1-4-hdi-engin ... -t172.html

You can find the the 'dog bone' Citroen C3 lower gearbox mount here.

Hi,

Thanks for the quick response C3CAR.

I actually replaced the mount you highlighted myself less than a year ago.

Not sure if this has perished in some way though, so I will check when I get a chance.

If this is all ok then any other suggestions please?

Thanks,

Hi,

after checking the gearbox mount I found it had indeed failed as suggested by C3CAR.

I only replaced this 6-7 months ago myself with a part ordered from an Ebay seller and have maybe driven 7000 or so miles on it.

I guess the moral of the story is to buy a genuine part from Citroen - which is what I'm about to do.

Upon closer inspection I found another problem.

I will post that as a separate topic.

Many thanks for the input.
