After our conversation, I have actively pursued the fault code 66-1 with our chief technician (who has been unavailable for the last few days) and he informs me that this is a brake pressure sensor fault code. Although the part number you have supplied us with does not appear in our database, we have also researched this number and found that there is a good chance we can repair this problem. We would need you to send in your module and block together as the problem is in the metal part of the unit. The cost of a repair would be £350.00 plus vat post and packaging making an all-inclusive total of £441.60 with a two year warranty.
Please feel free to choose who to manufacture your unit but in the interests of safety, should you decide to use BBA, please call them first to ascertain if they are still repairing these units by modifying them with external pressure sensors. We don’t do this, we repair the actual pressure sensor itself and we have received units that BBA have worked on to see first hand what they do. They may well have changed their repair by now but please check just in case.
