The MAF code will probably be because you blanked the EGR, so there will be more air taken in via the Air Filter to make up for what is now not being added from the EGR.

The EGR you fitted does seem to be the wrong one according to the info from Valeo. It may be ok for French variants of your engine.

If there is a clamp missing then some of the Exhaust gasses may be leaking into the Engine Bay.

It will be interesting to see if the car drives ok on your way home.

Well it was a better drive until the P0229 error came up or the P2463 soot one, or the P242F ash one. 

It attempted a DPF clean at the beginning of the journey but must have failed as from glasgow to M6 Penrith turn off (over 100 miles) the dpf went between 16-19kpa. As soon as I got off the motorway I pulled into a lay by, turned engine off and on, then cleared the warnings and set off. It worked for about 10-12 miles before the P0229 popped up and then the P2463 and P242F. I pulled over near darlington and turned the engine off and on again, cleared the warnings and no more errors came up and it done a DPF clean.

Today I drove 12 miles to the beach with only minor errors, the MAF one and the throttle ones, i'm sure these new ones are due to the blank. I'm going to keep the blank on for a few weeks maybe, and then buy a genuine EGR valve you posted earler. Might just get one from a breaker though, they're about £50 with usually a 2 months guarantee. 

But when I clear the warnings I basically have full power back. I wonder if the dpf 819.2kpa reading has anything to do with the dodgy EGR I have fitted, I might disconnect it and see if the pressure changes. It might be dragging down the voltage or doing some other electrical magic *****!!! 🙂 

I found an old photo of the EGR that was fitted to my car. It was a 2010 model but it was a Euro5 one, so I don't know if your one is the same or a Euro4 one.

It might not necessarily be the original one but it worked fine. 

I thought that someone might have chipped in to say if these cars can run with a blanked off EGR without fault codes.

 

I took a photo of the one I took off.

My car is: 1.6 TDCi Zetec (110ps) 5d (DPF) (08) also Euro Emissions 5. I'm sure i've been on other sites and its said mines a Euro4 but the Euro 5 came from Parkes search via Reg plate.

So exactly the same, well apart from the bottom line which is probably the serial number or batch code of the EGR.

Your V5C will tell you definitively if it a Euro4 or 5. I don't know what the difference in the part numbers is.

It's a Euro 5. I've ordered a 2nd hand EGR valve from a ford breaker. Probably fit it in a few weeks but might keep the blank on to see if any of the errors go away. I know the MAF and throttle ones probably wont be due to the blank but the other might.

It will be interesting to see if the new one is the same as your old one. I did notice that your one looks physically different to the one that was on my car.

Here's more photos of the original one I took off. 

It does look the same from your other photos.

My mk2.5 2011 1.6 TDCi has had a blank fitted for about 5 years and never had any codes or problems.

Well I might keep the blank forever then haha. Just with the new egr. Do blanks help with regens? Do people still gut their DPFs.

Just been to the supermarket and I had an oil service message appear on my car. Was only serviced last month. Strange I'll have to check the oil level tomorrow.

That's an easy one. With the doors closed switch the Ignition on and press the Brake and Accelerator pedals right down and keep them there for about 15 seconds and you will see a message on the display that tells you when it has been reset.

I'm sure It is a timed reminder that goes off a year after it was last reset.

Well it was up last month, got the car serviced and it wasn't there anymore. But just turned back up today. I'll give that a go to reset it. Then I'll have to check the oil level.

Had a good journey back to work today, carried out 2 regens, successfully I think!! Loads of power and only the MAF warning. I wonder if the DPF is starting to unblock. I also treated the car to some BP Ultimate Diesel. Going to install the 2nd hand EGR valve sometime tomorrow. Will update when i've tested it, i'm going to install it with no blank, then see how sh drives, if there's no power again, the blanks going back on until she dies!

Morning,

I've just finished fitting the EGR I bought from breakerlink. Took the car for a drive around where I work and it works as if it was blanked. I have loads of power again and now warnings, but it was only a quick drive around. Think i'm going home either Wednesday or Thursday so i'll update then when I get home. 

On the way up when I had the old EGR valve in and it blanked, I had a turbo underboost just pop up. I reset it and stopped the car (as thats the only way to clear it, or turning engine off and on) and it never came back. Maybe the DPF is still a little blocked due to the dodgy EGR valve. Next time I buy one i'll just use a 2nd hand one as you know your getting the right part for your car! We live and learn!

Fingers crossed. Out of interest, is the new one a Valeo and does t have the same number as the old one.

Yes and yes, apart from the bottom line which is different. That's probably batch and serial number maybe?

Well drove the car and she drives like a dream haha.

The only errors I got on the way up was P244A and P2002 which is DPF issue and was happening before the EGR failed. 

So I believe my problem is fixed. 

@Tizer thanks very much for all the help you gave me,  hopefully passes the MOT next week! 👍

That is good news and a lesson learned, there are times when it is wise to fit only OEM parts and other times when aftermarket ones will do. At least you can now concentrate on the DPF.

Personally I would reset the DPF Learned values again and monitor the Differential Pressure. If you are sure the tubes are intact, there are no Exhaust leaks and there is a DPF in there and the problem persists then I would bite the bullet and fit an OEM Pressure Sensor. I have heard that some people have had problems with aftermarket sensors also.

Good luck with the MOT and make sure that the car is warm when tested, I always used to take mine to a place that gave a timed appointment to ensure this.

The Plate (smoke) Value for these cars that was introduced a few years ago is quite low, about a third of the old test value from memory so the test is quite onerous now.

One way round that was to remove the Plate Value from the VIN Plate before the test and the tester was obliged to test to the higher default value but I don't know if that still applies now. The last I heard was that if the car failed and the Plate Value was removed for the retest then the retest was done using the Plate Value before removal. Someone with more knowledge of the current Diesel testing standards may know the up to date situation.

Hello,

Well the car is definitely running like it was beforehand. But I still get the DPF errors all the time. I've just put the car in for an MOT and it failed on 6 things, sorted it all though and cost £230 to put right, but thats cheap considering now it should hopefully last at least a year before I have to spend more money on it. 

I changed the Differential sensor today and reset the values as it was sitting at 30-50kpa all the time, once I reset it it went back to 0-4kpa. I still get it going to 812.9kpa when idling. I can't the MOT didn't get a warning for the DPF P244A - Diesel Particulate Filter Differential Pressure Too Low Bank 1. I reset it and after a few starts the  EML warning pops up on the display. When I picked the car up the Engine Management Light was lit up on the display haha. I was lucky.

If that gets picked up on the MOT it will cost a lot to fix!

£230 for another years motoring is not too bad and it must have passed the smoke test ok too.

I still can't get my head around the weird DPF values, It could be a PCM fault. I'm sure there is a full Electrical Schematic for that car somewhere on this site I'm not sure where though, but you would need a working donor car to compare values with your one.

Maybe a project for next year.
