2005 A6 4.2L

Just got back from the dealership because my ESP ABS light and parking brake light are on.

Per the dealership:

ABS control module is shorting out: $1810 plus tax

Parking brake control module shorting out: $554 plus tax

UGH!!

Anyone have these two issues and anyway to fix these cheaper??

Thanks, Nick

a good indy mechanic.

Did these issues escape the PPI? (Did you buy the car recently?)

I've had it 2 years. Seems just recently that things are going bad.

Call BBA Reman and ask if they rebuild 2005 ABS control units. I just did one for a friend on a 1999 A6. Took about 2 hours to remove and replace and they remanufactured the unit for $150. They may also rebuild the parking brake unit.

Normally there is not a rational way I would buy this diagnosis -- this feels like BS to me. Have you recently had a dead battery, jump started the car, or anything like that ?

Most likely, yes, you do have a lemon, your dealer is incompetent or both of the above, ncarvain. Sorry.

How could this be Lemon? the car is almost 5 years old. My 05 had a CEL light on, and needs 2 things replaced. It is only costing me $50 because it is CPO'd.

I would also take it to an independant that works on these cars for a second opinion.

Yeah... not sure how it is a lemon all of a sudden when things go bad on a 5 year old vehicle. That said, some of these units can be rebuilt or replaced much cheaper with used parts.

Well that is interesting, because I have been having a slow start issue, where I will push the start button and it will take a few seconds of trying to actually turn over.

Could this cause the ABS issue?

Plus, I have a 3rd party warranty, that has the ABS module on it. It should be covered. Dont know why I didnt think of it right off the bat.

Do you know how old the battery is? I would replace the battery. First. With these cars with sophisticated power management modules, when the voltage is low, I have seen all kinds of crazy things happen.
