C4 MK2 C139D
Hi all, new to the group, just bought an accident damaged c4, it needed a new ABS pump, swapped that over with a 2nd hand one with all the same numbers, bled it all and all is fine. Only problem i have now is error code C139D, longitudinal acceleration sensor, won't go away, anybody had any issues with this? Is it a case of swapping the sensor? Thanks

It means the longitudinal acceleration sensor needs calibrating using Lexia / Diagbox.

The time of appearance of the fault code varies from 100 to 640 milliseconds following the calibration of the sensor.

Thanks Marc, I have a foxwell diagnostic, can it be calibrated using this or is it Lexia only? Thanks

Re: C4 MK2 C139D
I really can't advise on this I'm afraid, as I can only advise on the capabilities of Lexia / Diagbox which is what the dealerships use. I really depends on the diagnostic tool's capabilities and you'd have to confirm this with the manufacturer.

There is a list of members with diagnostic equipment here and at the foot of the list a link to a map of their locations.
