Removal of EGR question

<< < (2/3) > >>

TimM:
The best advice is to junk the whole lot, blanking plate on the engine side, and a new hose (with no T-piece).

BUT, as RRB said if you simply fit a blanking plate this will be easily rectified should you have a problem with your MOT, and there will be no 'odd' signals sent to your ECU about a valve not functioning, because it still will be..... the vlave will operate, it just won't have any effect.

The blanking plate is LR Part No ERR4698 and the gasket is ERR7173

Just to be certain that everyone is talking about the same bit, this is your EGR valve:

Is it just as simple with a td5 discovery?and are the blanking plates available for the td5 through main dealers ?wouldnt mind trying this on my td5 as it seems sluggish when pulling away and when cold its even worse

Yes i,ve seen your post Gords and looked under your bonnet, yours looked alot easier to blank off than mine does.

Junking the whole lot is ok Tim but i,m concerned about the removal of the airflow bit and its related electrickery screwing up the engine management stuff and then i have to get more hoses to replace that section etc :?  i think i,ll start with fitting a blanking plate in place first and seeing what difference there is

Thats all mine has and it seems to go a lot better - maybe some of the increase was in my mind, but it feels a lot better.  :D

The theory is the same, and there are blanking plates available (they look the same as the TD5 but I would check before ordering), have a word with thermidorthelobster as he has either just done it to his TD5 or is considering it at the moment.

In effect, that's what I have too! All the electrics are still there, but I have just removed the actual valve and pipe and sealed the vacuum tube.

I don't think this mod gives you loads of power, if any. What it did seem to do was make starting off and pickup much nicer! It also, seemed to be a bit more responsive at lower speeds/revs. Generally, just a bit nicer to drive :D
