Accelerator Cable

[Socks]

The accelerator pedal in my C5 rests below the clutch and brake pedals... I 'hear' it is a simple job to tighten the cable. Can I do this from above the engine bay or do I have to go underneath the car? TIA

Which sort of C5 is it?

 

On my 2.2 HDi estate the cable ends at the throttle pot behind the battery, under the box where the various ECUs for the engine live. The slack can be adjusted there.

 

I would first get someone to sit in the car, engine off, and floor the throttle. Then you need to see if the there is any further travel in the pot with the cable fully tight. If not, tightening the cable further will result in the pot reaching the end of its travel while the pedal is still proud of the floor, and then the cable or pot is more likely to get damaged/break.

 

I thought the throttle on my C5 was way too slack, but the throttle is short travel, sits way below either of the two other pedals, and on examination was found to be as tight as it needed to be.

 

The cable is easy to adjust, but access to the area is the problem.

Thanks... found it. Access does look a bit tricky; wondering if I can get away with just removing the air filter housing and not the ECUs box? I'll do the test you suggest to see if there is any further travel in the pot.

 

Mine's the petrol 2.0 HPI model, btw.
