EGR blanking - leaving in situ?

[rw711]

Hi I am fairly new & have looked and read a good few threads already and got a useful amount of info, so sorry therefore to start yet another thread! 

My car is 1.6 TDi on 11 plate - facelift estate model .

It has been faultless & brilliant mpg for the first 12 months of ownership, just recently had one 'artificial' regen on the DPF to report (about 3 weeks ago) 

- now getting check engine and flashing glow plugs at some to most of the time - past 5 days - reading other posts I am thinking this must therefore be at the EGR? we are getting limp mode some but not all the time. 

I'd like to get the full EGR /DPF removal & remap in due course - but wary of the emmissions recall as we have the letter, plus do not really have spare cash for the whole job just now. 

My ideas are to start with the easiest/cheapest measures first, with squirty egr cleaner into air intake. 
I also think I can buy blanking plates which will disable the EGR without having to remove it in the short-term, as I understand it is difficult to get to for manual cleaning. 

I am keen to do non-permanent stuff too till we know the full implications of the recall? 

Any help/suggestions/or pointing out I am not getting it right welcome

cheers,

EGR for 2.0 TDI and 1.6 TDI is really hard to get to so cleaning with an oven cleaner won't be any good in this case.

I'm not sure if blanking plate works for these modern EGRs but I might be  wrong. I thought that these need at least some work with computer. Anyway, I had may EGR mapped out and it's still there but my car doesn't use it anymore and that's a fine solution for me. You may ask some garages for the price and maybe you can afford it right now (DPF removal could come later).

The emmissions recall is free take the car to the main dealer and get this done then they will give you a nice list of all the faults on the car,at least this way you will have an idea of what is actually wrong and get it sorted by a cheap indy or yourself if you can.

 

You probably already know but your car wont pass an mot if you remove the dpf it would have to be gutted then refitted and the sensor would have to be mapped out or you will have the eml light on the dash being an 11 reg car i am not sure what they check on the mot emmissions test it might be more than just the smoke test my 07 tdi vrs has, so a gutted dpf might fail on a later model .

This kit seams to be made for your purpose: http://www.ebay.de/itm/09-AGR-Ventil-Simulator-VW-Audi-Skoda-Seat-1-6-TDI-CR-CAYA-CAYB-CAYC-/181994497838?hash=item2a5fb7a72e:g:pC0AAOSwX~dWm-Qt

 

It consists of blanking plates and a cheating box, which plugs into the car's harness with three plugs.

 

My own 1.6 TDI had the EGR mapped out together with the tuning remap, but the engine stutters @~1400 RPM when the speed is constant, so I think the EGR is leaking, and I should get a blanking plate fitted.

 

Just fitting the blanking plate will put the car into limp mode.

Thanks folks, 

Yes I Had seen that kit on ebay good price- and was thinking that might do it, it would be easily remove  & replace  if it goes for recall. Do the DPF later should it become problematic?
- I got a quote (£475) for the EGR /DPF gut out (Supertune Scotland) - I asked about the MOT and they have re-iterated twice that the modification is 100% MOT friendly and they guarantee the work to that effect , but do state that taking for the recall would undo the remap.

 

  We are thinking of keeping the car long term as we like it so much, so it might just be worth getting it done so no future hassles ( we stay in remote area of west coast -  its 3 hrs each way just to get to Glasgow which is nearest city for stuff like this!!, though we have a couple of local garages they dont really specialise in anything particular)

Thing is I dont know how long til the recall, what they would do to it and whether it would be desirable. I dont really want it in limp mode till then if its 6 months down the line, though it would be good to get the list of faults free

Some of blanking plates I've seen have a small hole and claim not to upset the engine management?

Gonna try the Wynns EGR cleaner stuff this weekend, though would seem unlikely, its got to be worth a try!

I thought the recall was in place now ? have you contacted the main dealer to see if it can be done asap as its free ?

 

All they will do with the recall is update the softwear on the ecu for the latest information its the same as having a remap, so cars that already have a remap dont need the recall but standard cars may benifit from it,

 

I have the small hole egr exhaust port gasget on my car a vrs pd170 it stopped my light throttle hesitation its a vw/audi/skoda genuine part it only costs £2 mine took 5 mins to fit as my egr is on the front of the engine i think your egr is at the back of the engine, that spray stuff will have to go a long way to go to get to the egr if you spray it in the intake worth a try tho,

Best £2 I've spent too as the hole seems to get rid of the low revs jerkiness

Ooh, what's this you speak of? I have a slight hesitation around/just above 1.5k revs. 170PD too.

[wiilydog]

Its a egr blanking plate with reduced hole, its a proper vag part so there are no issues of eml coming on and fits perfectly. Mine was for pd TDI so not sure if there is same part for the 1.6 cr

How do you know it is the EGR or DPF?

 

The flashing glowplug light is used to represent literally hundreds of potential faults.

 

You really need to get the car scanned for fault codes before assuming a EGR / DPF delete will fix your issues.

Thanks, I had assumed that the flashing glowplug was to do with the EGR from reading other threads on the forum , I do know the DPF has a seperate warning light as this came on once then cleared when went for a decent run.  I am now in touch with a friend at work who thinks a friend of his may have a compatible VW device for checking codes so hopefully this should be possible before any thing more major gets done... 

I have done the wynns fuel system clean (Ultra Clean mixed into half tank DERV) and done the squirty stuff (Wynns EGR cleaner) into the air intake now - it hasnt improved things I didnt think it would but was the easiest /cheapest thing and probably good housekeeping as the car has not had as many long runs as usual with the season/weather...

cost not much more than a tenner off ebay..

I would like in principle to block the EGR anyway as I think it is a source of potential problems and few benefits- I am more in favour of keeping the DPF esp. whilst it remains trouble free as I can see it is useful for keeping particulate pollution down..

Willy0329 - I am not sure about the emmissions recall we got the EA189 letter from SKoda saying it would be recalled but they would contact us when ? _ I'll maybe give them a ring,

- again we live in a remote part of Scotland a trip to the dealer would be a full day out and half a tank of fuel, I'd also like to know what they are going to do before committing to it?

More when I get codes, would still like to block EGR I think?

 

[rw711]

P0407 is the code : see readout below. 

Cancelling the code and driving about 50 miles the light (glowplug flashing & EM light stayed off)
- it came on once then when cancelled again it has gone off & stayed off so far

-did the snake oil work and just take a bit longer to work its magic? 
-will the light come back on again? 
-should I still be thinking about EGR deletion long term?

We had EGR issues with our 10 plate Ibiza Sport 1.6CR TDI within 2 weeks of purchasing it.

Trader we bought it from paid for EGR delete (as I was going to have it remapped at some point anyway) and I paid a bit extra for DPF software removal and more torque/bhp.

As yet I have not had DPF physically removed but it will need removing at some point in the near future as it will block up in time. After the remap I fitted an EGR blank plate on the pipe as it enters the block which made the car run even better.

DPF will be removed by cutting out a square in the canister, knocking out the honeycomb DPF inside and welding the DPF canister back up. This will pass the MOT.

Even if you just have EGR delete it is a 'remap' anyway so you may as well have DPF delete and more power at the same time?

Thanks Dan - I think this is ultimately the best way forward- I know the 'holier than thou' comments about emmissions always come out on these , but VW developed these and treat them as consumables and they as we well know still f***ed up on emmissions - so we are stuffed either way the consumer is having the pish ripped out of us - you buy a 3-5 yr old motor expecting it to be 'nearly new' and not having huge problems!  - rant over 

I hugely like the Octy dont get me wrong, but I aint gonna feel guilty about the emmissions as the remap would probably save fuel - even if you go for the power option not economy it will hold higher gears at lower speeds (which is a bit  I feel of an issue with the 1.6 TDI -you really do have too start in first even when you trickle up to the lights still moving? )

-to me you lessen the amount of fuel burnt at the bottom line which therefore lessens the Nox and particulates. If the technology was reliable and treated as part of the car rather than a consumable I'd be up for any emmissions savings - but VW/Skoda had just done this to keep the EU govs happy without a thought as to how the consumer would get on with it when it went wrong - oops I'm ranting again - BED lol

Don't suppose you've got a part number for this have you?

I got a few quotes regarding the EGR deletion and other options - today I took the car and had the EGR blanked and deleted and stage 1 remap, at the same time the DPF was checked and it was recommended to be left in place as its condition and operation was deemed to be fine. 

The company I used said it was best to leave a fully functioning DPF in place if no problems with it -  as the MOT is only a visual check now it could become more stringent in the future, this suited me fine as it was saved me a couple of hundred quid over the original estimates for both EGR & DPF removing which was money I don't have just at the moment . 

Immediate noticeable results are of course fantastic wish I had done it sooner before the faults even emerged

-  big increase in driveability in terms of throttle response, torque and acceleration yet improvement in economy, as far as I can rudimentally check from the on board display is a relative increase in region of 5 mpg at 60-70 mph speeds - it is also now showing a tank which I have used approx 140 miles worth already as being good for another 725 miles - I've only ever seen it in low 600's on a brimmed tank before. Obviously I will have to monitor further before I can state anything more concrete on fuel economy but good signs so far....

Will report further as time goes on... this remapper is convenient & mobile for central Scotland I will supply details on request by pm- they seem to know their stuff but the proof of the pudding is as they say in the eating so I'll not just post the link straight up just yet

Hi RW711, I have exactly the same question.  I'd love to know how it;s going.  From reading around the subject i believe if I want to blank the EGR I need to make sure there is still DPF regeneration.  Also have you experienced any negative effects on DPF?
