Is it worth blanking my egr as its been mapped out
Why not just swap your manifold for a flapless one?I don't know about "Carbon Cleaning" you're talking about
But it's absolutely worth cleaning out the inlet manifold and EGR valve
It will seriously surprise you whats in there if you've never seen it before

And then after
Don't have photos of my EGR when it got cleaned out. But you'll see plenty online and get the idea
Everything gets absolutely caked and coated inside
That's what I did. I got the flapless one from Darkside, I couldn't believe how much build up was in my original one!Why not just swap your manifold for a flapless one?
Frankly because I can't be ***** taking it all off againWhy not just swap your manifold for a flapless one?
What do you mean "there is no real evidence the inlet stays clean"?My intact EGR has only been off once to inspect and clean, in the 60K of my ownership (Car on 230K+ now) and it was really clean. Never had the inlet manifold off but the car runs smoothly and with Shell V-Power diesel, 6K filter/oil changes it smokes very little for a non-dpf 140PD.
I should add, I'm alone amongst diesel 'enthusiasts' (or should that be lepers now? ha ha) in not believing in deleting anything, especially the EGR. Not for any wokey reasons however. Yes it keeps the engine cleaner with more performance, theoretically, but diesel is 'dirty' anyway and there is no real evidence the inlet stays clean, moreover the single biggest drawback is it takes longer for the engine to warm up, especially in the cold.
But just about every car that has problems, starting, idling and smooth running, that I have seen has had the egr deleted and/or been remapped. I've seen people like Beany chase these faults down the rabbit hole when my first starting point would be to put everything back as designed first. These things put greater strain on other components and the engine unfortunately was designed around increasing emissions regulations of up till then Euro 4. I'm happy with the relatively modest though smooth 138BHP and I believe, though just my opinion, if I want more power, it's a bigger better engine needed.
Yes sorry that was admittedly a silly thing to say, - what I meant to say was that cleaning out the intake often makes little difference to performance on these cars unless it's really bad (snake oil as someone called it) and as I say my EGR was relatively clean unblanked anyway. It's not necessarily harmful either to have an EGR - my car is on 230K+ as I said, smokes very little (it would even with the EGR blanked since it has no DPF) and runs sweetly. Lower emissions, which are only tested for CO2 though can't be a primary reason to do it, unless your car is regularly failing the MOT. Of course your Nox has gone through the roof now, so your actual emissions are higher obviously - which is the real reason they want to kill off diesels and what ULEZ is based on. I've only once failed on emissions and that was soon after I got it. A lot of things have been put right as standard since then and I've had no further fails. Tests are only going to get tighter and tighter and they've said they want to clamp down on this and DPF gutting. These engines are poor enough in that regard and were unable to meet Euro 5, which is why there were dropped in favour of CR.What do you mean "there is no real evidence the inlet stays clean"?
The evidence is there to be seen in the inlet manifold, before and after.
How can you doubt that not re-routing the exhaust back into your inlet manifold is beneficial?
Cleaning mine out, which was particularly bad from the previous own was like remapping the car.What do you mean "there is no real evidence the inlet stays clean"?

My engine also warms up quicker now and is down on emissions.
Link to the YouTube series please?Case in point, there is a lad on YouTube, who bought a very nice, low mileage fully loaded, 170PS Avant, even had the oil pump changed before he bought it. He instantly deleted the EGR, gutted the DPF and had it remapped; lowered - all that jazz. Then spent a lot of videos chasing down why it stuttered and was flat changing gear. One guy constantly told him put the ecu back to normal, even just temporarily to see - didn't listen and it still stutters, many videos later and a lot of expensive parts, including flap delete, changed.
I long ago I got over the embarrassment of vanman leaving me well behind at the lights (though Teslas still grate - I'd love to follow them for 100+ miles to see when they begin to creep along more slowly), though I doubt vanman ever gets over being left behind when the diesel Audi torque kicks in with a blip of 1 or 2 hundred rpms, on the motorway or the big brand new 4X4s not getting out of my way, up the steep European passes. No, I'm happy with the Old Goat as she his ha ha.
Owning a big fuel tanked diesel is like a case of the The Tortoise and The Hare. Enjoying the satisfaction that there is still nothing on the roads, yet invented that can beat them for going the relaxed distance
I agree tr7 - and Dieselgate was pure and simple US protectionism IMV - 1% of commercial and private vehicles there have ever used diesel. The EPA made limits so strict that they had to cheat, because gaz guzzling yank cars could not compete on economy or quality. The German's mistake was the hubris they had in thinking they could get away with it. And now Tesla is the most valuable car brand in the world - go figure, as they would say. Nonethe less that is why we are where we are now, everywhere - they are determined to kill a technology that still has a lot to offer and is the most economical user of fossil fuels and C02 'global warming' emissions have gone up.I don’t care one bit about the little emissions that may come from an egr being removed.
The entire topic is all a scam to bleed you of more money forever so you’ll be forced into an electric future where everything can be remotely disabled at will.
What does 2 stroke do

As I said emissions can't be a reason for egr delete, unless it's failing the MOT and if your intake is as bad as the pictures then I agree totally a clean out is in order, and maybe the real reason for any fail - I've not needed or want either, that's all.
I'm sorry but that is absolute snake oil - there is absolutely no need to add 2 stroke to your fuel and premium diesel is not a 'con'. I understand and can't argue with your reasons to EGR delete, however.Here's a quote from Gazwould in the B6 section. It ensures a cleaner diesel burn, and upper cylinder lubricant.

And how much extra has it cost you over those 10yrs compared to normal diesel?I would be interested in this topic
I put premium diesel in for the past near 10 years and not sure it's ever made a difference
Though maybe it's a case of a job well done is one that goes un noticed
I'm not interested in debating with Gazwould. I know this by having a 2.0 TDI 140PS that has covered more than 230K miles and runs like new. It has the original turbo, original everything from what I can make out and it has never received 2 stroke or Redex or any any other snake oil in it's life. Furthermore in over 35 years of motoring both privately and professionally, I have never used Redex or any other Godammed additive, except once, to no effect. What I have always done from a Sunbeam Rapier through many Jags: a 1983 XJ6 with an XK engine at 170K, when everyone said they needed rebuilding at 100K; an XJ40 at 250K - I got it at 100K and 6 years old. Is change the oil and filter at 6K intervals - Just that, no snake oil! And I will add that I saw a vid on YT recently of an 500K + 1.9 TDI Audi that had never been carbon cleaned and the mechanic, who took the engine apart and was very impressed, reckoned it had reached this mileage because a bit of carbon retains the seals on older engines. And my my car runs sweet and clean on Shell V-Power diesel . So you do what you have to do, I'll continue as I am.And you know this how?
Post a thread about 2 stroke and creat an argument about it. Gazwould (a very opinionated member) will debate you gladly.
Premium diesel is a con, although why mention that? It shows no benefits to fuel consumption or economy. I've done comparisons. Do you know what cetane booster is? It's cheaper than premium diesel

I see we have an infidel !
I've got 10+ years of mot smoke opacity tests to tell me what works on a diesel .
V Power is a con , no Cetane disclosure on the pump , add your own , much cheaper , JASO FB spec 2T , 2-EHN and the occasional Redex on a 186K Euro 3 .

The car was blowing 2.00 for years , thermostat a part of that but 2 Stroke alone took it from 2.00 to 1.00 , then the thermostat lowered , then 2-EHN lowered again , it's called G- Power or Gazwould blend , whatever you prefer .
B7Tourer what is your engine code ?
What are you aiming for? to pass the MOT, extend the car life or to help the environment? As I have already mentioned my car, at 230K+ has passed each MOT in my stewardship, bar the first time I bought it. And proper restoration to spec sorted that. It smokes so little I never see any much now, in the rear. But it is a BRE 140PD without a DPF, so obviously it must. I really don't care about the readouts unless it fails an MOT or there is some objective proof you can provide that this will any anyway aid longevity and I am damaging my engine by not following such an OCD schedule? Why do you think a low smoke readout is the single indicator of the ultimate health of your engine? It may be running too lean. Diesels are known as 'oil burners' - they already have natural lubricant, in the fuel by it's nature.I see we have an infidel !

What are your qualifications for all this? Are you a petro-chemical engineer? An engine designer perhaps? Are all premium fuels cons, in your opinion, or just V-Power? Why do I see a huge material difference between regular 'supermarket' fuel and V-Power? Am I just imagining it? Why are we not all using 2 stoke in diesels and why do all the manufacturers categorically advise against all such additives, in their manuals and upon request? These are rhetorical questions as you can imagine, since I am happy to proceed as I am, as I said, and you too obviously, but you have not swayed me or ingrained huge doubt. And as say I didn't come here to debate since, in this regard, I am not looking for a solution. If I am an infidel, my friend, then you are a member of a rarer sect than me
I doubt it. He wants to keep things "standard".The oil industry is incredibly secretive because they want to have us over , there is no such thing as 'supermarket fuel'.
I do hope you've taken care of your BRE and given it a modified remanufactured #2 balancer shaft with a longer 100mm drive key ?
It's booked in for July the 19th for the KMB upgrade + cambelt etc (Gear driven according to KMB - Kit 9). I have to thank you for that, sincerely. Even though this engine is now on 230K+ and given it is a very ordinary Avant, I would be surprised if it was ever done but it has lasted beyond the responsibility of its manufacturers and so I imagine long life and poor services killed lots of them. I'll report back with a photo of the hex key.I do hope you've taken care of your BRE and given it a modified remanufactured #2 balancer shaft with a longer 100mm drive key ?
It's completely negative to performance I agree, for ludicrous emissions strictness, but not necessarily injurious to a well designed engine. Are you not listening to what I have said - do you think I am lying about the mileage of my car? The 500K+ 1.9 PD I referenced earlier was untouched too.Explain to me (if you can, without debating) how putting exhaust gasses back into the air intake is good for an engine.
It's been likened to an engine eating its own poop. Engine manufacturers don't design their engines for longevity these days, or else how would they make money.
What is your "huge material difference"?
