[Rusty068]

Hi i have a xsara 2hdi estate,when at 70 mph on the speedo i,m realy doing 85 mph and at 30 mph reading my actual speed is 40 mph.

Is there a way to reset this or is it a garage job,many thanks in advance

That's worrying - how could you prove your actual speeds if caught by a gatso?

 

Hope you get a definitive answer and a cure for the problem - interesting one isn't it

the speed is normally out by 5 mph but the other way round 35 = 30 at least that's what my sat nav says, you cant alter it unless you have access to diagnostic tools, have you done any wheel mods? how do you know its going faster than the speedo says? sat nav by chance if yes then use the sat nav to control your speed till you get it sorted

Hi,car is standard with 195/55 r14 85h tyres,speed test was carried out driving next to 2 other cars via mobile phones to check.

The garage where i bought the car from are going to fix it,so w8ing till monday for any info/date about this.

Lots of cameras around my address so no driving it atm as i do not have any way of checking speed inside car lol

Hopefully it will be some kind of speedo reset

not a very good way to check the speed because the other car might have been pulling away from you even though you think it wasn't so very unreliable, good luck at the garage

Regardless of how i checked the speed it is still out by 15 mph @ 70 mph

trolling report indeed I would say its common sense and welcome to the 21st century, take the car into Citroen and have it re-calibrated ( you wont get much help with that attitude )
