hi all after some help with fault code 16352, checked fuses all ok and checked wiring thats ok, sent unit away to be repaired and was told it was faulty so had it repaired, refitted to car but still have same fault code present, any body got any ideas ?

I'd be speaking to the company that refurbed it as it doesn't sound right. 

the unit is currently back with them to be re checked,just waiting to hear from them, someone suggested to me it could be the ignition switch faulty or even the the dash causing the problem 

You could get the instrument cluster checked I guess. Keep us posted on how you get on
