Ticking noise accelerating

[striker200181673]

On my second Roc now, so I am quite in tune with the engine noises. My last Roc was a 2.0 TDI and this one is a GT Turbo diesel. What I notice is a highly annoying ticking noise when accelerating. Sounds more prominent from the drivers side, hear it most around 30-40mph but it only happens when the car is in motion. I’ve tried to replicate the noise when the car is at a standstill but nothing. Only when accelerating. Had it into two separate garages who said they can’t hear/see anything yet I can hear it clear as day and it’s driving me crazy. Car only has a couple of months left on its parts/labour warranty so want to get to the bottom of this before then! Any ideas?

Is it definitely speed dependant, rather than rev dependant? And is it definitely a 'ticking' rather than a 'rasping' or 'rattling'? I'm just asking as I have a sound coming from somewhere behind the dash when accelerating at around 2,500 rpm. Like you, the garage couldn't detect it.

I’d probably say it’s Rev dependant but the noise is just more noticeable at specific speeds. Pushing my foot on and off the accelerator I hear it but not if the car is sitting idle which is frustrating. It’s a difficult noise to describe, but more of a ticking noise. If I’m doing long distances I get a vibration from under the passenger footwell which happens every 2mins for a matter of seconds. Not sure if this is connected. The fact I can hear these highly annoying noises and no garage can detect it is very frustrating.
