Bump as well. Light comes on and goes off every day or two. My indy got both pressure 1 and 2 while car was running. Reset and pressure 2 was still at fault. Would love a DIY on this...

Edit: Found a small write up online: https://autotecdirect.wordpress.com/...r-replacement/

Can anyone confirm this is the best method for replacing the sensors and/or are there photos out there?

Bump again. Can anyone verify the steps on the link I posted above? Still have my DSC and handbrake lights on, somewhat intermittently.

Also, when you bleed the brakes (before?) performing this job, is there anything out of the normal bleed job that you would worry about (i.e. master cylinder bleed)?

Thanks in advance.

Default Re: DSC Pressure Sensor replacement

Finally got my sensors and I figured this was a good time to replace them as I was going to bleed my brakes for winter storage anyway.

Has anyone attempted this recently? Is it better to flush the brake fluid BEFORE or AFTER the replacement?

As long as I have the brake fluid reservoir full prior to removing the sensor, I should have enough in there where I won't bleed it dry in the time it takes to swap the new one in, right?
**EDIT** I didn't realize you need to take the reservoir off prior to removing the sensors. Can you switch the sensors over fast enough so all you have to do after the procedure is bleed the brakes as normal (IE no special ABS "pulsing" via equipment)?

Any other tips on this job would be helpful, since there isn't a lot of information online. Florian's diagrams (posted above) help a little bit, but there is still some uncertainty.
