So today i was driving around with my girlfriend and out of no where my ABS light came on and my brake light started blinking and beeping, and i noticed my brakes were a bit hard/rough when i pressed down on them..im thinking abs module immediatly but then it went away and would randomly come on and off through out the day. I noticed my car has a few blown fuses somewhere could a blown fuse cause this? also had this code for my abs
18014/P1606/005638 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction

Second i had this code when i scanned my car with my vagcom, i didnt have a check engine light but this came up 16826/P0442/001090 - EVAP Emission Control Sys: Small Leak
Could that be due to a vacuum/boost leak?

(i doubt its the gas tank cap)

 

Why do you say that you doubt it's the gas cap? From my experience, if you leave the gas cap completely off, the code will say "Large leak" and does throw a CEL. The "small leak" code is either a loose gas cap or a smallish vac leak. There's a vacuum check valve close to the EVAP purge solenoid, I'd be willing to bet that's your culprit there.

Which fuses are blown? The ABS/brake light problem could be a bad wheel speed sensor(s), bad ABS module, or just a blown fuse, but blown fuses are usually a good place to start.

 

Agreed with Chris - you can even blow out the caliper/hub area with an air compressor. Brake dust on the ABS sensor can trip a false code.

 

Does a bad sensor cause the brake light to flash as well? I don't recall the brake light flashing when I had bad ABS sensors, only a bad ABS module when the brake light was flashing.

If it is the ABS module dying, it usually will be intermittent, but get worse, until you get the ABS/flashing brake light all the time.

 

My fuel cap is new, anyway the vacuum leak is intermittent so im not going to worry about it for now, i replaced the abs module and everythings good now, i also checked my t fitting for when i installed my boost gauge and it was so bent that i couldnt even blow air through it, i replaced it with a stonger t fitting and now my car drives smoother and dosent make that loud air releasing noise.after 15psi, its still leaking boost somewhere.but now its not as loud. And i also found a nice oil leak coming from the filter area, ill takr care of that when i do my oil change soon.
