Skoda yeti 4x4 2010   

 my ECU keeps going in to limp mode  has a fault code which points to a crank sensor so we replaced 

 the sensor with a new one reset ecu off we go 2mls and back in to limp again

 fault again crank sensor but with  a 0.5volt short  glow plug light on on the dash plus engine manager light

any one any idler of what it could be ECU HAS BEEN CHANGED  

 

Did you clear the error code after fitting the new sensor? 

 

A 2010 tdi is probably suffering with the usual problems of EGR, blocked DPF, blocked ASV that affects these cars. 

 

The glow plug light is the signal for many a wondrous and expensive problem !

i have done all the checks but withno joy so last resort is map it out thanks for the help
