New EGR fitted, now what?

[kurienp]

Ps. On a side not and a different thread, I still have noisy suspension after replacing lots of the common components. So frustrating!

If you start a separate thread, I am sure you will get a lot of inputs. Do describe the kind of noise and that may help on suggestions.

Maybe the noise is from under the van and not really suspension? Maybe some of the other components hung under the van?

The exhaust system is a classic culprit.

The EGR valve and cooler are a consumable, like a clutch. You just need to budget for it.

Agree!

The pre-indicators to this in my case was higher (but normal as per VW) oil consumption - approx 1l every ~ 7000 mls/11,000 kms. The oil has to go somewhere. And the first place it can go into is the EGR cooler I guess and that clogs it up?

A proportion of the burnt oil residue will end up in the EGR and the rest goes to the DPF. Eventually the EGR valve fouls with carbon, doesn’t close when it should and the EGR re-circulates exhaust gases constantly when it shouldn’t. This further fouls the EGR cooler and valve with carbon, eventually the carbon completely blocks the EGR cooler and prevents the EGR process.
The icing on the cake is the carbon being blown past the piston rings by the high boost pressure into the engine oil.
How to destroy an engine.
Add to that the option of an extended service interval which appeals to fleet owners and it’s game over when it comes to reliability / longevity.

Hello. Yes I had EGR valve and cooler replaced at a cost of £1400. Luckily it was covered under the 3 month warranty from the garage I bought the van from.

No it's not.

Look, I can selectively Google too....

So your argument is that it's legal to remove the EGR, but in doing so the van is no longer legal to drive on public roads?! That's the epitome of dancing on the head of a pin.

Back to the age old question of whether to remove the EGR, and have trouble free motoring, or pay for a repair every few years then!

As I read it, of the egr etc is factory fitted (which it should be on vehicles past a certain age) then you cannot remove it and pass an MOT - and if you have no MOT your vehicle is it road legal.

Making a vehicle illegal to drive on the road is an odd path to take in my mind. If you get caught out it will end up being expensive, more so than regular maintenance.

So with regular maintenance, the EGR isn’t a problem for the engines , and they will run care free for many miles , as with other diesals?

Doesn’t mean it has to sound like a bag of shit over every bump! Commercial vehicle….

Mine is a 2017 204 DSG 4MO and at 50,000 gave the EML light. A check with Carista showed that it was the EGR fault. A £99 check at VW did not tell me anything new (I know, money wasted). I am now considering this as a service item to be replaced every ~50,000 mls.

Got the van with ~7000 mls on the clock and since then have had no issues other than this coming up now after 50,000 mls. All regular services done. Got VW extended warranty but have refused to cover this under the extended warranty.

@TeamD - if you don't mind me asking
a) did you replace both the valve and the cooler? Not sure if I need to replace both, but might as well.
b) how much it cost you. VW are asking me for £1500 for the EGR replacement (both the cooler and the valve).

Ta!

Strange that the extended warranty doesn't cover the EGR cooler. I recently had my EGR cooler changed under the All In warranty with no problems.

O wow! That's great. Which dealer (if you don't mind sharing)? We will all flock to them then.

A condition of all motor insurance policies is that the vehicle is maintained in a roadworthy condition. If an insurance company did some digging and found that an emissions system that’s required for UK MOT had been disabled you might end up with a bigger issue than poor EGR reliability.

There are lots of circumstances where it is legal to do the mod, but illegal to use the vehicle on the road with the mod. Number plates for example.

My MOT tester told me that actually the MOT is very limited and is restricted to what he can see - he is not allowed to move anything- so if you cant see that the DPF/EGR has been modified he will not make a comment on it (a bizarre circumstance he aslo advised is that windscreen faults are what can be seen FROM THE DRIVERS SEAT. So if there was a stone chip that was clearly visible from the outide but had a screen mount sucker or something placed over it on the inside, he would not be able to fault it!!

The only emissions check on my most recent MOT was a smoke test, carried out after the engine had been running for 10 mins and after me driving up the motorway. Apparently it jsut has to register a reading. the probe wasnt in for long and came up with 0.00, so passed withflying colours

The UK MOT Manual MOT inspection manual: cars and passenger vehicles states exactly what should be tested.
The UK MOT Testing Guide for Test Stations also describes the sanctions that will be taken against a MOT Inspector who doesn’t comply.
Why anybody would potentially put their livelihood on the line in order to pass a potentially illegal vehicle isn’t clear.

Not sure that I’d go for the sucker cup over the windscreen chip as the Inspector can simply say that the vehicle was not presented for test correctly. I’ve seen a MOT failure because a rear seat belt receptacle wasn’t visible, it took 5 seconds to make it visible.

@DXX which part of my post suggested anythigncontravening those guidelines? The comments he made were based on what he had clearly been told by his MOT instructor

None, but you’d be chancing it by covering a windscreen chip.

 

[doningtonphil]

I think his point was that if the sucker was there, he wasnt allowed to remove it. And the check is only to be carried out from the drivers seat, so even if he noticed it while walking around the outside, if it aint visible formt eh drivers seat then cant fault it.

Maybe stickling to the 'letter of the law' rahter than the principle of it. But I digress, I think the point is that people can do alls orts of mods that an MOT wouldn't necessarily be able (or required) to observe.

I agree with the mod’s getting through MOT’s. One thing that’s guaranteed in the not so distant future is that emissions tests for MOT’s will evolve and be more stringent.
