De - Egr'd correctly ?

After trying several different things to improve my fuel economy (19-20 mpg on 6 mile run to work at 50 mph) I want to check the following details with anyone who can help

The EGR valve has been removed and blanked off from my 300 tdi auto EDC Discovery (p reg 1996). The EGR control solenoid wiring is still plugged into the solenoid. The 3 pipes that run from the solenoid are connected as follows The Pipe that went to the EGR valve is now blocked off. The pipe that went to the airbox is still connected. The pipe that runs to the brake servo vacuum hose T piece is still connected.

I have removed nothing or unplugged anything from the fuel pump.

Now some boards I have read say just block off the egr valve pipe and you can leave the rest. Others have said remove and unplug it all including the wiring and cover from the injection pump.

Can anyone shed any light on the right and wrong way.

I am getting the timing and tappets checked soon. For info it is de egr'd, decatted, allisport intercooler, allisport chip (removed at moment to test economy), I know the 265/75/16 AT tyres wont help or the underbody protection and winch bumper but the economy is real bad especially when I read in the mags I should be able to get better.

Sorry if you read this on another site just trying to get a broad spectrum of help on this issue.

Hmmm, I initially just placed the blanking plate inbetween the EGR output and the pipe that takes the air to the pipe from the intercooler.

Only just got around to trying to remove the lot. So far I just removed the EGR itself and unplugged it from the solenoid and the rest is still connected as yet again it started peeing it down when I just start somethin...!!!

Still need to take the one from the air box, the one that goes around the back of the engine and remove the solenoid. But it's still running fine. I do feel like it might not be pulling as well as it did but not sure if that is just mind tricks as I know I have not finished the job.


Out of interest, how did you blank the pipes off?

bit of silicone sealant onto a bolt then just push it up the pipe

Or alternatively use a blanking cap like those used on the end injector leak off pipe.

19-20mpg's not far off the mark for a short run, i tend to average 22-23 driving like a granny - as soon as you start driving swiftly under 53mph expect it to plummet... hence why i asked the question about 'overdrive override' for the Torque Convertor!
