Hi,

 

New member here so sorry if I'm missing something obvious.

 

My Octavia Mk2 1.6TDI had the issue with the flashing glow plug which cleared after restarting, took to garage who said no fault logged and may be duff fuel. Filled with premium fuel and all good for two days, then glow plug lamp came on straight away, turned off then when on again engine management light on as well and wouldn't clear. 

 

Took back this morning and it had logged fault regarding exhaust airflow improbable or some such, he tells me this is the egr which is a nightmare to get to i.e expensive.

 

Happened tonight and drove home with engine management light on, car drove normal apart from light on dash

 

Before I lose the little sanity I have left could there be any other faults before I fork out big bucks?

 

Are the spray cleaners any cop or waste of money?

 

Also can  anyone recommend an independent garage they would recommend in Aberdeen/shire area to do the job?

 

Thanks in advance

Welcome to Briskoda  :sun:

 

I don't suppose you have the fault code do you? This website is good for cross-referencing them...

The EGR is a quite common complaint on the 1.6 CR105, see here for other complaints and rough repair costs...

Could be worth taking it for a long enough drive, at a suitable RPMs to cause a re-gen to happen.  My parents 1.6TDi (fabia) has similar issues shortly after they first got it.

Sometimes, theirs would go into limp too, iirc.  They had it scanned, but nothing obvious came up, think a few drives up motorway sorted it.

Aren't you thinking of the DPF? I'm not sure a EGR does a regen & if they do I stand corrected

There is a difference between EGR and DPF. I often drive long distances (~200 km) but anyway I had to remove EGR. DPF is fine, though...

At first you have to positive about that EGR thing and when you're certain, you have 3 possibilities:

1) take it and clean it (don't know how easy it's for 1.6 but for my 2.0 EGR was hard to access. Might take some time but the expenses could be next to nothing.

2) map it out. You need somebody to do it and it will cost some amount of money. It has one advantage though - when it's done, it's done forever.

3) change the EGR valve to a new one. The most expensive way to go and it might happen again. Probably you shouldn't choose this one.

Yes and no :-)

 

I was think that DPF can cause the glowplug light to flash and loss of power (based on what we assumed was the problem with my parents car)... thus I was suggesting an alternative issue.

 

As I understand it, access on the 1.6 to the EGR is a bit of a pain :-(

Many thanks for all advice,

 

If I can find someone who can map it out I think I'll go down that route as slowly driving me insane.

 

Happened again this morning, engine man light on straight off then flashing glow plug which wouldn't turn off, it gets a 35 mile run across all road types mainly 60mph + twice a day so no short journeys. I live near local Skoda garage who told me that its prob EGR but couldn't tell for certain till on diagnostics. He advised me that if I continue to drive it I'll most likely kill the DPF. Nowhere free till next week though.

 

Going to try for goodwill from Skoda as three and half years old and 24K on it. Prob pi$$ing in the wind with that but worth a shot.

 

App its at the back of the engine on 1.6tdi, might try one of the sprays as an interim measure.

 

Cheers

It's a bit of a long shot, and as you have warning lights on already it may be a little beyond this fix, but working the car quite hard through the gears on a regular basis has been known to fix one of the main EGR issues - heavily coked or clogged up EGR's.

Tried one of the sprays today and it seemed to work. Parked it outside work for four hours and it's back!!! Argggghhhh!!!

I did go through the gears giving it death on way back after spray treatment so not sure what worked now. Only common factor in all this is heavy rain but not sure if any connection.

You need someone to read code. Could be the fap differential pressure sensor

 fault code 7563 - ERG SENSOR 1

 

This was fom the VDCS system - Glow plug light flashing and engine management light on limp mode .

I did replace the ERG valve and fault fixed. I did take some time to look at the old unit and discovered that the internal valve was sticking open due to a worn open lever onnce cleand and some  lub seemed ok. However do not think you can get to it without removal and at that stage better to fit a new ERG as such a pig of a job to replace.

Hi,

 

I've booked it into garage next week, but ex mechanic at work looked at it and pointed out EGR and its at the front not the back? Everything I've read or been told says this is right at the back at the ar$end of nowhere on the 1.6tdi and hence expensive. He was confident this was the EGR and to take it off and clean it shouldn't be too gruesome.

 

More confused than ever!

 

Any ideas?

If its 1.6 cr tdi. It's at the back of the engine. Has 2 cooling hoses on it. One hose on left one on right.

It is at the front on the older PD engines, see here...

However, on the 1.6 it seems it is right at the back, see here (scroll down)...

 

http://www.car-surgery.com/news-hot-topics/

 

"We can offer a complete solution for EGR failure on all VAG 1.6 TDi engines that are installed throughout the range .

 

This effects most cars from 2009 to present. The engine will go into LIMP mode and reduced power, also the engine MIL and glow plug will be on or flashing.

 

The typical cost of repair at the main agents is over £1000 and a typical independent garage would be around £700.

 

The main reason for this high cost is the location of the EGR valve assembly. Access to the EGR valve is very limited on the rear of the engine block. The typical labour time to remove and install and new EGR valve is between 5 to 7 hrs. The typical life span of these EGR valves seems to be around 4 years or 60,000miles."

Thanks for those, mine def looks like one in picture so still confused? its a 1.6 tdi 61 plate, but are there two egrs? Sorry if stupid question but I'm stumped if not.

Can anyone confirm this is the ERG?

 

Thanks

 

I just Googled the part number just underneath it in the picture (03L 117 021 C) and it came up as being the oil cooler.

 

I'm guessing the part pictured and the part with the part number on it are separate?

Can anyone confirm this is the ERG?

Thanks

Looks like an intake flap motor. Egr is behind the engine almost impossible to see unless you get underneath the vehicle.

This is what you are looking for.

This is after removing Dpf filter subframe and steering .

Yep, the mysterious object on the picture is oil cooler (it does from this angle looks like an EGR, but it isn't) And as Falpperjack is pointing out, the big silver shiny thing is a cooler for the EGR system where the EGR valve is sitting somewhere on left of the picture...

A better picture.
