The sensors are integrated in the bottle, you have to change the entire assembly.

Damn im fucked, thats why my dealer told me i need to replace the entire reservoir , damn . Tooo expensive just for the fucking light .

check with mazmart.com and finishlineperformance.com for cheaper reservoirs...

if you have later version of the reservoirs, you just have to buy the bottle, sensor will be re-use.

check the TSB.
