Have you had any EML after fitting the blank?
Ive got the same engine an want to do it but worried about an error coming up
Not a thing. I know from my own research that others have fitted the blanking plate to the 1.8 TDCi and it's been fine. If any errors are thrown up they can be cleared, but so far all positive.
Throttle response is better, boost and overall power through all gears increased - simply a nicer, more enjoyable driving experience. I was always aprehensive pulling away from lights as the car could / would labour in certain weather conditions, cold starts, low fuel level - no longer.
Do it... worse that could happen is you may decide to remove.
