Slip control and over drive lights flash UPDATE post#5

Yep - I have exactly the same! Apparently it's the delimiter/speed converter that's at fault. It won't affect the car except you can't use MANU mode or play with TC on/off. Mine's been like it for months and it's on the 'to-do' list!

I still have the problem with the o/d and slip control off lights flashing

 

I have tried the following which has made no change

 

1. Tried the car with no speed converter/delimiter at all

2. re-soldered all wires for the above and triple checked against diagram

3. Tried a spare ODO

4. Replaced Throttle control ECU

5. checked resistance on the sub throttle control valve and sub TPS on the throttle body

6. Replaced both the fuse and relay for traction control

 

The only thing i havent checked is the speed sensor on the autobox

BUT the car is not displaying any ecu fault codes which makes the speed sensor surely not at fault
