Lacking power in lower revs
Well I left Bournemouth and all was going so well. I got 10 miles from Sandbach services and I noticed I had lost fine throttle response and Power in the lower revs. I pulled in and cleaned out the maff sensor with brake cleaner (it was all I had) no joy so I called the AA
The AA man was great, he couldn't see any codes on his machine and suggested I was towed home. At this point I must point out I'm on my way to Inverness. After I refused he then spent an hour helping me strip down the egr pipes and clean it all up, plus a squirt of egr cleaner in the valves.
Now after another 10 miles it did improve a bit but its still lacking any power at low revs. I'm now in Lancaster services wondering the best course of action.
I'm getting no dash lights or warnings, just lack of power.
You're not too far from Flack if you can get hold of him.

Thanks but past Flack now. Managed to get her up to Glasgow, it drives better in sport but if I'm in town I have to keep gears low using cc.
I'm moving onto Inverness tomorrow, is there anyone in Inverness or Glasgow with an iid tool I can use please. Will be leaving Glasgow at lunchtime ish to goto Inverness.
Think an iid will be my next buy.

Guessing you are going to go right past him as he’s not far from the A90, assuming you are not heading up the A8
Might be worth your time to give him a call

Many thanks to XDAndy, I went to disco Mikey in Dundee and he diagnosed a stuck open egr. I blanked the faulty egr and left the working one open. 125 miles later and no dashboard lights and power is restored.

Excellent news!
So, you going to blank the other side, or recondition them both?

Fairly sure the issue is the head of the EGR valve has fallen off. Electronically, both valves were operating correctly

Again thanks for for the help,
I will probably leave it with the one blanked, I want to see if it will fail the new mot emission test on egr Blanking.
Unless anyone thinks that's a bad idea for the engine, my thoughts are the car will perform better with out any egrs, 1 egr is better than 2, if the mot test requires the ability to see the egr working then maybe 1 working may fool it. I may be completely wrong but that's how I see it.

Don’t think there’s a ‘test’ for the EGRs as such.
It’s a visual inspection, from what everyone says, and they are not allowed to remove the plastic engine cover to improve access.
So, if they can ‘see’ it’s been blanked then it will fail.
The workaround people are proposing is to put the hose back into place with the blanking plate at the valve end sandwiched in there like a gasket. The screws are apparently long enough.
That way, from a visual perspective, the hoses are still intact so the system looks operational, and there’s is no way to identify they’ve been blanked.
That’s the logic anyway.
From an emissions point of view, the overwhelming opinion is that the car runs cleaner when blanked anyway, so shouldn’t impact on that side of things unless something else is wrong.
