telltale and warning lights

[ALEXJ]

Hi people need some advice.While driving the telltale light and the brake warning light went on and permanently yellow.( The triangle in the centre and the brakelight ) This was the first time yesterday that this happend but prior to this the run flat indicator randomly goes of aswell then i reset it then ok for now but days later it goes on again then i just reset it again .Is this a big issue what do i do now???? I drive a e46 318i 04

sounds like a problem with your DSC , as all those are functions of the DSC controller on a 04 e46.. guess you should have error codes checked first.

DSC problem. How is your wheel allignment/tracking?

it is lately funny will check it out thanks

Might also be a problem with the wheel speed sensor, sometimes if they are dirty they can also cause problems with the DSC system.

actually more than likely a wheel sensor problem come to think of it, since the flat tyre indicater also depends on the wheel sensors..

faulty sensor caused by slow punture you had.

Buy new tyre or fix ur runflat. then buy a sensor -its R193 at BMW

i had car checked out and the computer says Pressure sensor 2 code 5e21 what does that mean

i checked every wheel no sensors on the valves, clean all over with air pipe, pressure right on every wheel,alinement in order,balance of wheels in order,and still warning lights on But lately its on and off as i drive what next to do

where in cape town is the best place to go to have the pressure sensor replace for e46 318i and what am i looking at in cost if u know

 

[netercol]

you 04 e46 does not have sensors in the wheels to check the pressure, its a function of the DCS.. the DSC monitors the rolling radius of the wheel and if it deviates from the set values it assumes the tyre is flat.

thats why the fault is probably a wheel sensor, the wheel sensors signal is used for stability control, abs function, wheel presure monitoring ect.
