The "chugga chugga" is mostly normal when the EGR operates, and when you switch the engine off. I would worry more if it was silent...

You can remove clean and grease which will keep it quiet for a while but ultimately it will fail again so if you are hard up for cash go for this option otherwise buy a new one and prior to installation strip it and grease all moving parts with appropriate grease

Apologies for highjacking but I have been told mine is showing error codes for EGR, MAF and 2nd injector.
I don't have any warning lights on, the EGR makes the typical noises on switching off the ignition but it is running like a pig. If the EGR makes the three noises is that enough of an indication that it is working fine? |

OK, it seems to be a tad noisy indeed, but at least you know it's operating.
I've been in a similar situation with mine. I had the EGR disabled/unplugged for some time, and when I re-enabled it again, the soot had clogged up the EGR because the cleaning cycles where disabled as well (I reckon Ford/Land Rover put the cleaning cycle on shutdown for a reason, engineers usually don't add things without reasons...) Mine was actually worse because it was making that awful screeching sound even when driving! What I did at the time is the following: 1. Drove with 2SO added for a few tanks - that alone made the screeching sound go away 2. Installed a partial blanking plate which reduces the amount of exhaust gas being "recycled" (item #110934139626 on ebay, few quids and a couple of hours to install) 3. Left the EGR functional so the cleaning cycle would remain at shutdown. That was tens of thousands miles ago, and my EGR is working perfectly (AFAIK) and it's still the original EGR... I do get the MIL light from time to time (less lately), I simply clear the fault with the scanguage. Now, I am no expert, what worked for me may not work for others, I don't know, but all in all, it cost me a couple of quids, an hour or two to install, and that saved me the hassle of cleaning/replacing the EGR. “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique. -- 2009 2.4 Puma Defender 90 SW 1979 Land Rover Series 3 88" |

I had that, brought a new EGR valve as cleaning etc only lasted a few journeys before it started coughing again.

One more "observation", I noticed that premium fuels make the matter worse (again, in my case, might not be true for others), as if it was running dryer... So I use regular (yet branded) fuel. “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique.
