got the random ABS light with flashing Brake light going on. Hopefully it's a bad wire, please be a bad wire.

I am nervous. There is a rash of ABS controllers go out lately.

Be afraid. Be VERY afraid. Not if, *WHEN*.

Default It can also be a bad ABS sensor. VAG it. If it's the module...

you'll sometimes get bizarre readings when you scan it (or it won't communicate with the VAG at all).

Unfortunately, they are HORRIBLY expensive. I'm not a big fan of Bosch ABS controllers in general.

Cheers,

Is that true? No wonder we could not do VAG on our friend car (his ABS is out)

Default The other modules should still "report in" as they normally would...

if you can't VAG the car at all, that's indicative of another problem.

1 month ago, I did recode his ECU. Now, we could not access to anything.

Did he add an after-market head unit in between?

Default He did. We did measured the voltage across the K-line....

and yes we did got 12V. I drop the resistor 1K in and the voltage drop down to 7V. We exactly as that article from Ross-Tech but still could not read anything. We bring the VAG over to my car and another guy, the VAG works fine. Can't figure out why. We recoded his car a month ago. Now we can't read anything. His ABS was out before we recoded the car.
