Everything went perfectly, I can only recommend it.

From the first phone call, the order processing, to the shipping everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red light for the airbag). Today the message came from SWE, the car is running again, the red light is off and the HU was also passed. Once again many thanks for the help in need. Keep it up and maybe word will also spread in SWE that Airbag 24 does great work. Regards Gerd
