Did a journey of approximately 100 miles yesterday. On three occasions (at roughly same distance between incidents) heard a low level metallic clunk (presuming from the gearbox) which sounded like it may be a valve or the likes "closing". The gearbox then locked in a gear and would not change gear. At the same time the messages "Gearbox Fault, ABS Fault, DSC not available and Cruise Control Not Available, all appeared together. 

Each time I stopped the car, turned ignition off and re-started car. The messages were still showing but cleared when the car was driven away. This same procedure was carried out three times during the round trip of approximately 100 miles.

Have this morning used a code reader and there are no codes recorded other than the manufacturer control code.

Gearbox service (Oil and Filter ) was undertaken on 24.04.2021 @ 61049 miles. Current mileage is now 67904 miles.

Questions:

a/ Are these incidents connected in any possible way

b/ Is it at all possible that the gearbox transmission Fluid could have become low and how would one check that. (I ask that question because oddly enough, I seem to recall that on at least two of the three occasions I had turned 90 degrees right at traffic lights. Wonder if the fluid was caused to slop around in the gearbox, thus causing the message to appear?

Any advice, explanation or suggestions on fixing fault would be very appreciated.

Best Wishes and Regards, John

hi

need to get codes read, ideally with Jaguar ids/sdd, or a Icarsoft LR V2, ideally when the fault is present, once you turn ignition off and on it will clear

could be something as simple as a abs sensor, gearbox relies on the abs sensors to shift

also turning at a junction may be a sign of abs fault, as you turn the wheels spin at different speeds and the abs kicks in, hence why some time when you pull out of a junction and floor it, it just pulls real slow and once the steering straightens up, she goes like a good un

Many thanks for the information. I thought (obviously wrongly) that once a code had been raised that it stayed there in the memory until it was erased manually, via the OBD2 connection.

I always carry a hand reader but do not make a point of carrying my iCarsoft PRO, maybe I should carry the iCarsoft as well.

Hi

some codes stay logged some dont and it depends what code reader you use

the icarsoft should read them ok

did you sell you laptop/jaguar ids/sdd setup in the end

cheers

No never sold it, seems nobody wanted to buy it. Still sat in a corner of the dinning room. I could never figure out how the hell to use it, so bought an iCarsoft PRO, of which I am nowhere near at a level of learner in understanding how to use it. Cheers, John

UPDATE:

Problem solved and repaired. Rear o/s wheel speed sensor. Small cheap part .... caused big problem.
