EML has been coming off and on with one of our cars but thankfully, no limp mode. The book says it's the EGR and it's been on a reader too which says the same. It's 2013 1.3 diesel Corsa and it's a common fault after about 50,000 miles, which ours has now done. EGRs ain't cheap for this model, starting at around £110 plus fitting. The water cooled version is £502 :runaway: but I'm almost certain our's isn't water cooled.

Apparently, EGRs can be cleaned, the best way obviously is to remove it and clean it on the bench but it is a pig to get off apparently. I don't mind that but finding the time to do it when the car is outside isn't easy. Anyway, there are a few lotions and potions out there that promise to do the job but there is one in particular, a Wynns product that has a good reputation. I picked a can up last week and aim to do it today but is there any proceedure I should follow? The instructions say it can just be sprayed into the air intake for the EGR but that's a long pipe and I'm fearing the product may get lost on its' journey to the EGR, so I'm thinking just remove the pipe and spray almost directly onto the EGR.


Any tips?

ta much.

Mine would have been 700 odd from Honda so I had it blanked off and mapped out.

The lower price seems pretty good for a new one.
 
I ran a mondeo 2.0 tdci with the egr valve blocked off for two years ,two results from it it was fast as fxxx and fuel consumption was up in the mid sixties per gallon ,don't know whether it had been remapped or not but a super car

isntt defeating emmisions systems illigal and terribly harmful to the environment?

but let me guess you don't care?

No it's not illegal. If you breakdown due to a blocked egr, rescue services will just blank it off to get you going again.
 
what a crock of s***e more BS from people not interested in pollution and environmental damage.

fill your boots folks as long as peoples lungs are effected not yout wallets huh?

And what a load of save the planet crap you keep spouting ,the egr valve is one of the most problematical devices ever invented ,it costs drivers hundreds of pounds to fix when it clogs up and the recommended cure to stop it clogging is to go for a long fast run on the motorway ,it's like giving a alchoholic a case of scotch to stop him drinking .
A ill thought out appeasement device

That's DPF's not EGR's. Only way you will reduce the clogging is use decent fuel and not the rubbish fuel that supermarkets sell. The only way to completely cure it is block it off in the first place.

Yet you are perfectly happy to be driving around in 7-10yr old vehicles which pollute more than a 2yr old or newer vehicle which would meet current emissions regulations.
 
Is it illegal to remove or disable your EGR valve?
Technically speaking it is “illegal” to tamper either any emission control systems on a vehicle.

According to the DPF guidance sheet on the .GOV website.

It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use.

A vehicle might still pass the MoT visible smoke emissions test, which is primarily intended to identify vehicles that are in a very poor state of repair, whilst emitting illegal and harmful levels of fine exhaust particulate.

This includes DPF removal, EGR value removal / modification and strictly speaking ECU remapping. For EGR valves this is a grey area as you car won’t fail its MOT with the device removed unless it causes the vehicle to emit more than the allowable emissions limit.

This has to be one of the most ridiculous comments made on here IMO.
If supermarket fuels were rubbish, then there would be cars breaking down all over the place - and there are not.

Not rubbish at all, supermarket fuels contain a higher percentage of biodiesel which doesn't actually burn so well. A few of the bigger brands continue to use diesel with a lower percentage of biodiesel. A car that runs only on the latter and then run on the supermarket diesel will run slightly roughly until it adjusts to the poorer fuel. Readjustment can take as much as 1 or 2 tanks of the fuel.

So this fuel tanker that leaves the refineries to deliver to Shell, BP, etc, stops before he gets to the supermarkets and stirs in a load of extra biodiesel does he? Cant see it meself.

The different fuels are supplied at the refinery. Just the same as you can get 98 Ron and 95 Ron petrol. Or do you think they stop off somewhere and add some octane booster.
 
ah well i suppose my 2.5ltr volvo auto tdi isn't gonna get me into eco heaven .but i do love the nice cloud of black smoke behind it when i give it some welly :police::police::police::police:

That is because all the soot just builds up in the exhaust laying there waiting for you to put your foot down. If you leant on the pedal a little harder more often the build-up won't happen you will get less back pressure build up in the exhaust and the engine can run better. You probably won't see any or much of a decrease in mpg neither.



On the subject of fuels. I saw a 17 plate Hyundai this morning with a sticker in the window next to the fuel flap saying not to use biodiesel.

I was told by the guy running the new Costco fuel station they add the fuel additives as it's pumped into the storage tank, I read a few years ago that the fuel came out of the same tanks at the refinery but each tanker had different variations of additives for different customers so I suppose the supermarkets get some bio put in before the tanker leaves

The main problem with diesel cars was the government encouraging people to buy unsuitable cars with £30 PA or even free road tax and manufacturers with claims of 70mpg when a lot of small diesel cars never leave the town the owner lives in clogging them up,

Isn't using biodiesel supposed to be better for the planet?

Only in the sense it you can grow and harvest the source for the fuel and it's easy to "instantly" replace instead of drill for it and wait a few more million years until more vegetation has decayed.

Unfortunately, the massive loss of rainforest to produce biodiesel is not so good for the planet! :mad:
 
Bio Diesel is in many ways more destructive than normal diesel as has been said.
massive plantations have been given over to it and have driven local populations into food poverty and starvation.

Quite a few large corporations now routinely buy large tracts of land in foreign countries for this and largely get away with it due to local corrupt officials.

A lot of biodiesel is made from recycled products such as vegetable oils.
More of a concern is the damage it can do to engines, which, I assume, is why Hyundai put a sticker on their cars warning owners not to use it. Modern diesel fuel systems can struggle to cope with the stuff, especially when it can leave a green slime behind to block up the system,

Not a LOT, a small amount in the bigger scheme of things.
 
All I know is that DPF problems have cost me over £2k in the last 8 months, I'm all for saving the planet but these emission control devices aren't exactly reliable!
