Hello all first post so hello all I'm a newish owner of a 2007 2.0tdi PD Scout I live near Taunton in lovely Somerset (notice lovely applied to Somerset). Really love the Scout ideal for my needs carrying stuff and going dowm mucky lanes and on beach etc. Great car until this morning when I  filled up with diesel at Tesco then off to an appointment 25 miles away. About half way the engine management light came on and flashing coil light. The coil light was intermittent when on reduced power when off power as normal. I got to my appointment and stalled a few times while parking. The way home was a different thing all together no power and flashing coil light with increasing amounts of grey smoke showing in rear view mirror. Smoke become heavier and power was dropping to extent I struggled to get up a minor incline in second gear. I realise I need to get diagnostics run on it but trying to gauge likely causes and pre-empt amount of post Christmas spending pain likely. The car has 105000 miles on her and is in good shape for the year well serviced etc if that is relevant. Really appreciate a few ideas I've got a code reader that can read obd and obd2 codes it's an Autel Maxilink ML629 so may be useful? Car in process of being recovered right now but tool box at the ready. Thanks in advance 😀

Sight unseen etc, that makes me think of over-fueling and/or burning oil, depending on smell.

My suggestion would be injector wiring harness going by the symptoms

Yes, but that can/does cause over-fueling...

Mr AA recovered my car now and according to his diagnostics its the EGR. Car struggling to rev and no power along with smoke this sounds plausible? Thanks for input anyone else had similar? Cheers all

Selly

What were the fault codes?

 

What colour was the smoke, blue, black or white?

 

The reduced power will likely be limp-home mode, especially if the EML was on and / or a flashing glow plug light.

 

Plan for between £700 - £900 for a replacement EGR, if this is indeed the fault.

 

Until we get a look at the codes we're all guessing...

Sorry for delay in replying. Fault code read by AA was P0403 (EGR) local garage looked at it and run additional live data diagnostics saying its a full DPF. They don't have my confidence after offering to take the DPF off the car spray de-greaser into it (their words) and jet wash it. I tried to get the car a couple of miles to home but too gutless. Billowing white smoke and smoke now coming from a rather hot EGR region of engine when I pulled over and stopped after 1.5 miles on way back from garage. At a bit of a loss what to do next - DPF Doctor? Anyone used them? Or should I take another line of enquiry, clean out EGR valve first? Pulling my hair out.

Take off the hose on the input to the EGR manifold by sliding the spring clip and then the hose pulls out, have a look inside and see if it's all gunged up with black crud !

Cheers sparky planning to follow a thread I found on the forum with instructions how to clean EGR on my model and year Octavia Scout. That is if I can getmmy car the last few miles home as it didn't make it from the garage just 4 miles away 😮For others in the same predicament I found this useful looking Instructional:

 

Got our DPF cleaned here a few years ago. Been fine so far.

Are you sure it was diesel you filled up with?

White smoke is unburnt fuel, a pointer towards an inoperative DPF.

 

Excess heat is from repeated attempts of the regeneration of the DPF.

 

I'd start with a professional DPF clean (taking it off, spraying degreaser in and then jet washing it out is a rough and ready fix, a quick fix, which reduces the effectiveness of the DPF and will see you in the same position in the not-too-distant future).

Hi thanks for your input I really appreciate it. As I understand it the engine burns the fuel and produces exhaust gasses which still contain some combustible gasses the egr cleans some of the exhaust gasses by reintroducing a proportion back into the cylinders which in turn delivers cleaner gasses to the dpf which burns off the soot. I'm just trying to figure how the dpf being blocked and probably also the egr are causing white smoke in this chain of reactions.

 

The latest is I've got the car being towed, as its now a non runner, to the DPF Doctor in Langport Somerset. They plan to do a full diagnostics £75 plus VAT then phone me with expensive update I would imagine. DPF clean which they say is effective even on a full like 90 odd % DPF £250 plus VAT. Likely needs the EGR cleaning or replacing so I'm bracing myself and haven't ruled out scrapping my lovely Scout. I'd go to £1k on repairs then bail out. Only had the car since last November so comes in as my worst s/h car buy ever (ignoring the Fiesta that my brother in law sold me 25 year back which blew up). Wish me luck and the grace of the Skoda magic fairy.

re EGR/DPF That's not quite correct but you've got the gist of it.

 

I still don't think the diagnosis is correct given the white smoke.

 

If it's unburned diesel making your car look like a Red Arrow it would definitely smell... dieselly.

 

I'll wait and see your next update, good luck.

The white smoke stinks of unburned diesel. Never had any previous lights on showing the DPF was being or needed to regen so a bit confused 😕 - very sudden and terminal problem (well terminal in that the car doesn't even run now). I'll post a update for those interested when the garage have looked at the car on Wednesday 15th.

Bit of a coincidence it happening just after filling up.

 

Again, are you sure you didn't have a brain fart and fill it with petrol... Only suggesting it since you're a relatively new owner and you wouldn't be the first.

 

Just to rule it out, perhaps you have the fuel receipt, maybe even check with Tesco to see if they had a technical problem-no doubt other motorists would have contacted them if so.

 

Just saying.

I will check but 99% sure I filled with diesel done the petrol mistake 3 times last time 8 years ago and I'm sure that's the last. Cheers

OK folks the latest in the saga of my 2008 registered 2.0tdi PD Octavia Scout. The garage have informed me the DPF is full and also a metal flexible pipe that comes off the DPF is broken so needs a new DPF £723 fitted (pattern part). The turbo is shot £740 fitted using an exchange unit and includes oil and filter change. They have managed to get the car going of sorts to enable more complete diagnostics to be run. They say they are unable to tell if the EGR is gone too as they are have only got the engine to run "of sorts". So total bill to fit the turbo and DPF plus diagnostics and investigation work so far is £1650 but no guarantee the EGR won't turn out having issues once the other parts are replaced. I would reluctantly part with £1650 to fix it which is probably only £1k less than the car is worth. My dilemma is the unknown EGR status bearing in mind it threw a P0403 fault code before it became a complete non runner (read first post for background).

I Would very much appreciate some experience based views on whether there is any way the garage can assess the EGR health to get me closer to making a decision on whether I get my wallet out or call the scrap yard. Not my finest second hand car purchase so far. Cheers all

Ouch, that's a sore one.

These parts may(not) be correct for your particular model, you must check.

Edited 16 January, 20206 yr by MicMac

Great thanks for this MicMac much appreciated. Going to have a think over the weekend. Anyone know what other parts are part of the EGR system as in solenoid valves sensors etc in addition to the £23 valve MicMac has posted a link to. Just thinking if the EGR is knackered what is the likely cost to replace the whole EGR system in a worst case scenario? Many thanks

I didn't say this but if it's a 2007 PD then you could go dpf delete and it should still pass the MOT...

What's the significance of the 2007 model?

from memory 2007 and earlier models are a lower emissions standard and hence will pass the MOT without a functioning dpf

All fine in theory, don't the MOT examiners use registration/VIN to check if a DPF was factory fitted.

indeed they can but the MOT currently only visually checks the presence of the DPF cannister.
