Transmission malfunction Daf cf

I’ve just bought a 17 Plate 18Tonne Daf/CF 230. Two days after getting it a warning
Sign came up: Transmission Malfunction. Turned the engine off and waited half an hour before restarting and it finally went off. Same thing happened yesterday. Once it had gone off, I drove it to local mechanic who plugged in diagnostics, but numerous old faults showed up. They cleared all faults, to help determine which ones are relevant if it does it again. This morning on starting up, Transmission Malfunction came up again. dumped the air with the break pedal, and watched the pressure build back up on the display and the warning has gone off so seems to be linked to that. Any ideas? Obviously will get it back in for diagnostics but be helpful to have an

It’s a Daf get used to it

Www

Had to check the date of this post to make sure it wasn’t posted on aprils fools day.

Low air will throw up transmission fault warnings, but they should disappear when correct pressure is reached.

DAFs have a reputation for cracking of the outer insulation of the wiring loom, water ingress leads to multiple faults. That is better on newer vehicles, but I dont know from what date the covering was improved. Bit of a mare tracing faults there apparently.

As you say, back to workshop for a new reading of fault codes and take it from there.

When the fault is displayed it seems to struggle to get the revs up, but once the fault is off it behaves like a dream
