P0489 egr

[Hellboy80]

Had p0489 pop up this morning so cleared it and seemed ok the small distance I had to go. It came on just after I came of the motorway. The code relates to the egr so thinking about just blanking it. 

 

Been told it easy enough but might need to get it mapped after. Any recommendations in or near Birmingham and what price am I looking at? 

 

Cheers.

Also will Wynns egr cleaner work on a 1.8 tdci

it wont hurt it but then it probably wont work either.  

you need to have these blanked off before they go wrong, if its unable to move due to it being caked in carbon then unless you get it clean, you will still have the problem, blanked or not blanked.

Check out the electrical connector first, give it a good clean with contact cleaner, scrub it down, then do the same on the valve.  a corroded connector might make the ECU think it has a problem when it doesn't.  if your EGR valve is full of crap, then you will need to get it cleaned, replaced, or mapped out.

Do I need to get it mapped if I blank it off?

nope, it should be fine, I don't think there is a air flow sensor on this version.  some had a wee sensor that measured airflow through the valve, blanking it would stop it and throw up a DTC error code.  The problem you have is that its already showing a problem with the EGR which wont go away if you blank it.  thankfully the 1.8 is about the most common engine in existence so parts are a plenty should the worst come to it. :) id defo give cleaning those connectors a shot before trying anything though a mates 1.8 in mondy had egr issues and its almost certainly an electrical issues rather than mechanical,
