I wiped the control module code off the ecu and now I have a fault code 01044 and abs on and traction light is on so I’m just wondering if anyone can help me fix it or how to get the code that was originally coded into it or what do I do to fix this problem

Volkswagen modules are very specific. They must be coded correctly or safety systems shut down. So if you don't have the old module the dealer or shop with ODIS or advanced scan tool can do it too.

There is no way around this. Sorry, can I ask if you still have the old module? Ken

So when you say I wiped the code off the module do you mean I cleared the code and it keeps coming back? If so it sounds like you have a bad ABS control module and it need to be replaced.
