My local garage fitted my prosport oil pressure sender about a month ago, and it worked for about a week and then the gauge just started flicking from one figure to another as it had done prior to the sender being fitted.

Yesterday, my mechanic replaced the sender with a new prosport item, and the gauge now displays the correct reading BUT constantly flashes white and red.
Has anyone else experienced this behaviour?

I know the wiring on the Prosports is exceptionally thin and rather dubious quality, but if anybody can help me fix it I'd appreciate it.

Thanks in advance!

 

make sure the connectors are pushed in the back of the gauge correctly, use a flat head screwdriver, common fault on prosports.

also if its the peak versions you may have set the warning light too low/high by mistake.

hold down the button to adjust

 

Will do; peak is definitely set correctly, checked that one straight off
