Wiring probably. Just go to a workshop, tell them the problem and it should be quite simple to fix.

[Minmax]

Dont know is my needle broken or wat. but looks like its not the needle problem, cos my mileage meter also not working liao.

Get the whole thing replaced. Your car still under warranty?

[Minmax]

no, coe car.

[Chisiang]

common with older car. lucky if it is just the motor behind the dial that is faulty. Unlucky if it is the speed sensor which cost most.

[Minmax]

any place that can recommend to do such stuff?

wats the pricing like?

It would be interesting if this happened to the fuel gauge needle.

Looks like a intermintent problem - not sure what type of speedometer system you have.

Suggest you check wheel speed sensor pick-up for dirts, grease etc. The other possiblity is loose fuse/poor wire connection / dry soldering at circuit board.

COE car is like tat....

 

last time my COE car also got this problem.... only once in blue moon, it will happen...

 

mine can be 0 in the whole journey. then next day, ok liao....

 

or travel halfway, the needle drop to 0 and stay there for 5-15mins, then it goes up to normal speed readings

 

i just ignore it. as long the car can move on the road, engine no problem, i will be happy.

 

to do this repair can be quite costly, because they have to take out the dashboard to check where is the faulty part... labour cost will kill you here. the spare part can be cheap.

[Minmax]

where is the check wheel speed sensor??? my car long time nv wash liao. maybe its this problem..

 

if it going to be ex,

 

possible to DIY?

[Nothingtodo]

not possible to DIY. Better get it done by Mech.

 

It could be due to wiring, or the linkage from your speedo to the engine block. Should not cost more than $150.

 

So long your RPM meter working, no worries lah.

[Minmax]

150 ....

[Nothingtodo]

150 too Ex? anyway, I just guess the cost only. I face this problem with my 20yrs old car last time. Chked around to repair but end up buying a new car

 

I can PM you my trusty old electrical guy if u like. Let him chk yr problem w/o obligation.

[Minmax]

ok pm me pls
