I'm posting this here for a specific problem I'm having with a 2007 VW Passat 2.5L 5-Cyl. engine conversion ... a brake light switch fault. I've had this fault from the beginning of this project and can't seem to get rid of it. (The ABS errors in the scan below are recent ... I had the Brake light fault long before the current ABS issues occurred).
Today I cleared the fault for the umteenth time ... then I drove the car.
Everything works fine ... for a while. The brake lights work ... the green foot peddle light on the dash goes off when the Brake peddle is depressed ... the cruise control turns on and "sets" fine on the freeway ... and depressing the brake peddle deactivates the cruise control fine.
But today, after I had cleared the code, I drove with my VCDS open to Address 01: Engine (CBT) ... Fault Codes - 02 ... and watched for the Brake light switch fault to show up (don't know if VCDS faults show up in real-time). It took about 5 minutes of driving to get the fault to appear ... during that time I set the cruise ... applied the brakes ... used the turn signals ... turned on the headlights.
I was trying to find anything that might set the fault ... but really found nothing ... other than simply pressing the brake peddle ... eventually.
Any ideas as to why the switch would be fine for a while ... but throw a fault after about 5 minutes?
Here's today's scan ...
