Hi I cant get my FBH to work at all Fob flashes red when I try On iIID tool imgetting fault code B129A-88
Does anybody have any ideas what this means
TIA

The LED indicator signals various states and conditions for the heater as follows:
• Illuminates green when the ON button is pressed, then quickly flashes green to indicate that the heater operation has been requested.
• Illuminates green followed by red when the OFF button is pressed to indicate that the heater has been requested to shut down.
• Illuminates green, then quickly flashes red when either the ON or OFF button is pressed to indicate there is no communication with the receiver.
• Illuminates green, then slowly flashes red when either the ON or OFF button is pressed to indicate that there is an error.
• Flashes red when either the ON or OFF button is pressed to indicate the remote battery is empty.

The error code you are getting along with a flashing red LED suggests the FFBH heater fuse may have blown or a FFBH fault stopping communication between the FFBH and the ATCM. It could also be a wiring fault between the FFBH and the ATCM.

The FFBH fuse is in the smaller luggage compartment fuse box, position 16, 20A (yellow).

Have you had the FBH heater working before .

Does it work from the screen? Might be worth a trying 1st?
