Need some advice please

[krazy lil lady]

I've had my subaru impreza 2.0 gl sport auto for over a month now and noticed the speedo is out about 7 on low speed and 10 on higher speed does anyone have any idea on wot the problem is please 

[stants]

Has it got stock wheels & tyres on it or are they bigger ?

Different size wheels can effect the speedo,

All speedometer 's read slightly over by about 5mph

I've already checked that they have the right wheels and tyres on it for the age of the car it's a p reg 1997

as stated all speedos are slightly out - I cannot remember if yours is an electrical pick up or gear and cable feed so could be worn gear or resistance of wiring breaking down slightly

Ok thanks I think it's gear and cable ill have to get it sorted it's hard work with it not being the same amount out

Its normal, I drive loads of different cars and use satnav's all read faster then actual gps tracking. some are 3 miles out some are 10.

 

Think its the governments way of tricking us into going slower

Mine is 5mph out at 70. My dash cam measures speed and states I'm doing 65. Also on standard size wheels. I think it's a manufacturer safety cushion.

Just thing of it this way, if you always stick to the indicated speed you should never get a ticket [emoji23]
