I’ve just started getting a knocking/clicking noise when taking my foot off the accelerator. Presume it’s transmission related. The car is a 2014 CR170 4x4 with a manual gearbox. Done just under 50000 miles. The noise disappears under load; might still be there but I’m a bit deaf. Anyone got any ideas?

Could just as easily be brake pads moving, or worn drop-links on the anti-roll bar.

Is the noise there when going over a speed bump?

Sorry don’t know. None near me. On a straight level road at 30 or 40 you can hear it coming and going as you lift off the throttle and then reapply. Speed related as frequency increases as you pick up speed. Thought maybe cv joint as I had something similar on a previous car, though from memory that was more prevalent going around corners. Seems to have come on very quickly. Thought at first I’d picked up a screw or a nail but the fact it comes and goes would suggest otherwise. 

I have something similiar on my 4x4 2L TDI (TDF EDITION) - Its more noticeable after the cars warmed up - a sort of sound which is like someone hitting the underneath of the car with a cable (intemittantly) - I notice it when accelerating from a standing start or braking. Its not the brakes as they have just been replaced (pads & disks) and was doing this just before having them done.

What about a worn joint on the driveshaft from front to rear? Had something similar a long time ago on a triumph spitfire driveshaft

It turns out that the front nearside wheelnuts were loose . Near side rears weren’t properly torqued either. I had my summer wheels refitted at the start of May and it looks like the guy that fitted them has cocked up. I’m a bit disappointed as I’ve used the same local tyre emporium for years. Ive never felt the need to recheck wheel torque settings in the past but I guess I’ll be doing that in the future. 

 

The car was looked at very swiftly by West End Skoda in Stirling, at their newly opened premises.
