Cores (your old ABS unit) are to be in original, undamaged condition.  Nothing previously sawed open, broken open, hacked up, tampered with, slathered with sealants, physically burned up, broken into pieces, have liquid inside, etc.  If you are unsure if your module meets the criteria, consult the pictures at the bottom of the page or contact me.  If your core is damaged, trashed, etc, you need to contact me before sending it back.  I often hear "I bought the car that way", "I didn't do it" or "My mechanic says it looks fine".  Common sense dictates that I'm not going to take ownership of a problem that I didn't create.  

units that carry a refundable core charge will be charged $5/day for each day late over 21 days.  The exact same type of module must be returned in original physically undamaged condition.

IT IS YOUR RESPONSIBILITY TO INSPECT YOUR CORE BEFORE RETURNING IT, ESPECIALLY IF SOMEBODY ELSE INSTALLED IT FOR YOU.  

-Any module that has damage from somebody attempting to "solder" it from the exterior of the case will not be accepted.

-Any module that has a silver sticker or white sticker that says "rebuilt by an independent rebuilder" will not be accepted as a core return.  These have been cut open, sealed closed with epoxy and had the original capacitors inside replaced for no reason.   This includes any module cut open and then sealed closed with epoxy.  Don't bother removing the stickers, I can tell by looking.

-Any module with orange BBa-Rem** stickers will incur a charge for any damage to the module.  These will be examined on a case by case basis.  Don't bother removing the stickers, I know what they look like and where they come from.

-Corrosion in the socket area of the module or liquid inside and broken coils on the bottom of the module.

-Case damage from attempts to open it or remove it.

-If you choose not to return the core, collection action will be taken.  You will receive a bill for the average price of a used ABS module, of which you will have 30 days to pay.  After 30 days the bill will be forwarded/sold to a collection agency.  To be honest, there's nothing I hate more than having to go to lengths like that, but experience has shown that there's always a few that refuse to send the old module back, even after agreeing to the terms to do so.
