Range Rover 2001 P38 2.5td.
I have noticed the car is not as smooth as normal, It feels like transmission, not a continuous rumble but more like a tyre with a nail in it. I have now got the traction control light appear on the dash. I 'm not sure if it is just me but the brakes and steering seem to be affected. There are no faults showing on the Nanocom. Any ideas?.
 
TC light lights usually when it thinks a wheel has no traction so it brakes the wheel that it thinks is just spinning.
When mine comes on on an ICY road it is the same feeling as when ABS kicks in for a skid. A B-r-r-r-a-a-a-t-t-t- sound and you can feel it through the pedal. 2001 is probably same as mine "WABCO-D" 4-wheel TC. Not seen a Wabco-D ECU go "pop" and they are getting harder to source, so I hope it isn't that. Strange that Nanocom sees nothing.

comes on when the pressure is too low as well
 
Abs warning light comes on also now. The only fault showing on Nanocom is front right sensor is lower voltage than the other three. Do I need a new one? or will my sledge hammer fix it?

Depends how much lower.
I think they should all be showing about 2.3V (from my faulty memory maybe).
They should also present about 1200 Ohms of resistance (again from memory) but its all in my thread where I fixed mine over HERE.
