Hi everyone, got a second hand low mileage 1.4tdi (2008) fabia a few weeks ago and has been fine until this morning.  Got a beep and dash message 'Exhaust Workshop!', followed by the engine management light (no DPF on this model).  After reading a few posts on here i was wondering whether someone could add their wisdom.  The car appears to be driving fine (not driven it far - only to get it up to temp, as i've heard low temps might affect sensors), pulling through all gears, no fueling problems as far as i can tell, usually tractor like rumble on idle, not driven it far enough to notice mpg loss, and not noticed any oil leaks/or using oil.  I heard mention of egr pipes and sensors, injectors failing, egr failing etc but no mention of the engine managment light coming on following the initial message.  Firstly is it normal for the eml to stay on after this fault and secondly (i have not have a chance to have a look at the pipes yet/egr connections yet) i presume i'd notice if i had a bad injector on a three cylinder diesel and i presume i'd definately notice if the egr was stuck open/failed - would i presume right?

 

Does anyone have a guide of what i should be checking for on the the egr pipes and sensors, obviously splits in pipe work, re-seat any connectors.  Is everything fairly accessible under the engine cover?

 

I have a wifi odb connector would anyone know what specific codes would mean (as i say not had a chance to look at it properly yet).

 

thanks

Leon

 

Could be a whole manner of different faults... Sensors, egr, etc so the best bet, if you tried disconnecting the battery for a while and re-fitting and it still stays on, is to get someone to run the VCDS diagnostics on it. This will be far more accurate then an obd scanner, unless its a good bit of kit!

Ok, so a little update on this for anyone who's interested.  i had a quick look an hour ago and all the large egr pipes look in good order, however after taking of the engine cover i noticed what looked like an area of wear round the top of the small egr pipe (the smaller vacum pipe that goes from the top of the egr to what looks like the ecu).  the wear was near where the pipe connects to the egr itself *maybe wear is the wrong word - more like a malformation of the pipe rubber at the join*.  i thought it quite interesting that it seemed the correspond with the shape of the underside of the engine cover so i lined up the rear of the cover back on the engine and lifted it to see where it was rubbing, i didn't see where it was rubbing that bit but straight away i could see that the rear edge of the engine cover had worn a groove further back along the small pipe.  It had worn through what looked like the outer sheath of the pipe (there seemed to be an inner core?).   i cleaned the pipe and wrapped a bit of emergency hose tape around it replaced the engine cover and started up.  the exhaust workshop message came up and the eml was there.  i since popped to the shop and after a short run the message is gone and no eml.  surely it cant be that simple lol.  ill see how it goes but does anyone know what replacement pipe i need to order - i couldn't see any part numbers on the pipe itself, it is just a standard bit of rubber pipe?

It could easily be that simple if the pipe had worn right through to the point it was leaking.

 

The pipe you refer to seems to be the one near the  clamp no. 9 in this diagram? https://skoda.7zap.com/en/cz/fabia/fab/2008-608/1/131-131020/#17

In which case it doesn't show an individual part number but the whole assembly of all the pipes going into the solenoid valve block is item 17 in that list. (Yours will probably be the last one, suffix AP; there may be a part number on the manifold section where it connects into the solenoid block).

 

That looks like it would probably be expensive, so if I were you I'd see how your patch lasts, modify the engine cover so it no longer digs in, or re-route the pipe if possible to avoid the contact area. Maybe just cut the existing pipe where it's damaged and join in a new length with an inline coupling?

Thanks for both your comments mrgf, Wino, it is very much appreciated.  i had instantly booked it in to my local garage to have it scanned but have cancelled it for now in light of the patch seemingly working (will be cutting/coupling and adjusting the engine cover at the weekend).  thanks again.

Hello, just had the "exhaust workshop!" message on our 2008 1.4TDI Fabia. Obdeleven was also reporting an "intake flap motor" fault with a code P3103

 

After removing the engine cover and looking at all of the hoses I also found the small hose connecting to the EGR had a large groove worn through the outer rubber and cutting into the inner tube. There didn't appear to be a hole but I guess it had started to leak.

 

The hose is right at the back of the engine as per this diagram, circled (ignore the arrows) and is marked "7" at the manifold end.

 

 

By the looks of it the rear engine cover mount has worn away within the cover causing excess vibration and it wearing the pipe. (The cover was lose at the back and would not "clip" on)

 

I was able to cut the bad section off of the pipe and re-attach it to the EGR and cleared the fault.

 

I have also modified the engine cover slightly to allow a little more space:

 

 

And added a piece of rubber foam tape I had to provide further protection:

 

(I'm not sure how that will hold up with the engine heat though)

 

To reduce the vibration on the lose engine cover I also added a small piece of garden hose over the rear engine cover mounting bolt.

 

Thanks for the comments above for helping me quickly locate the fault.

...Just a thought but the small, rubber bobbins that hold the engine covers on often get sort of shrunk or worn and loose. I have had one or two go missing and first thought it was the dealer, when servicing, failing to ensure they were put back in place, so to speak.

Anyway, that are quite a cheap replacement from a main dealer and actually dearer usually, on eBay etc so worth ordering. 

You may find they have become less effective at holding down the cover and stopping it vibrating. I have swapped out mine now, twice since owning the car so if they are either missing or loose, I will replace them.

Thanks might order some
