Problem sounds like it could be an input/output sensor if its in safe mode and no lights displayed. Running a diagnostic may be your best best.

Hi Adrian, i am also in Wales, just a bit north of you in Porthmadog. The first thing to try would be to remove the input and output sensors and give them a good clean. They have been known to collect metal particles on them which affects their sensitivity leading to the safe mode fault. The scary thing with your description is the lack of the flashing "n" telling you that there is a fault. If it is not flashing the neutral symbol then doing a fault diagnosis would be impractical as it is not registering with the ecu. The input sensor is the one that causes most of the faults but it could be either one in the end. The cost is a bit of a factor as camskill want £122 and change for an input sensor. As an off chance, if it has been chipped from kph to mph give the wiring an inspection as there may be a loose connection in there somewhere that could affect it and cause the symptoms you describe. What happens if you disconnect the battery and reset the ECU? Does the same thing still happen?

Thank I shall try the input/ output sencor

[adrian1977]

Nice to meet you. Glad theres another fto owner in Wales .Yes I have try disconnected the battery and still the same problem.

[goz_83]

Battery needs to be disconnected a good 15 minutes for ecu reset

Today I changed the input sensor but still no change, tried getting the output sensor it seams almost impossible to get it out, I pulled that hard with my fingers they slipped off cutting some of my finger s to bits. Any easyer way to get it out as I've got to get two out, because I've got a spare fto and on the spare my gearbox works fine.

Use WD40 or other penetrant oil and soak it overnight.
Then use a pair of pliers and put a spanner at right angles through the handles and hold and twist should give you enough
to slowly turn the whole thing and lever out.
or a Large spanner just larger than the base of the sensor.
They can be a female dog to get out.
Also as said before the aftermarket speedo delimiters can be badly wired causing the same problems shown
