Skoda Superb, glow plug light flashing, loss of power

twin_beacon

2012 skoda superb, 1.6 tdi 105bhp
On the way to work, around 45 mins into the journey the glow plug light start flashing and I had a loss of power. Pulled over turned the car off and back on. Problem went away. After around 10 mins, it happened again. Again, turning it off and back on and it was fine. I was at work at this stage.

Has anybody experienced this before? From googling the flashing glow plug it seems it can mean many different issues. Going to try to get it to a garage this evening and get the error codes checked.

Could be a number of things.

In my case it was the EGR valve.

Dam, that's what I was afraid of.

EDIT: looks like that's the problem alright

This recently happened my wife's 2010 Superb 2.0 TDI which has the same EGR setup. I ended up bringng it to Coby Auto's and they deleted the EGR and DPF along with the required software changes so I never have to worry about it again.

On the VAG cars the flashing glow plug light is essentially another engine warning light and is often accompanied with limp home mode same as the actual engine warning light.
My Tiguan has done it a few times, rarely ended on a cheap fix.

Although I love to drive VW, most of my cars have been VW, and was considering Skoda for my next, I think I’ll move to Ford for better reliability.

Until the NCT make a functional DPF a pass requirement.

Sooner the better too. Chape tax and polluting the air with particulates and various other gasses. Time diesels started paying the cc rate of tax.

"Chape Tax"? DPF's started out in and around 2005 and "Chape Tax" came in half way through 2008, plenty of people are out there on the older tax bracket with DPF's. And what is paying a higher tax rate going to achieve when it comes to your point of air pollution and various other gasses.....where is your point on this?

I had one deleted on my old car purely because the over all cost of a number of related fixes would have written off a perfectly good car. Was quoted €2800 for an inlet manifold, EGR and DPF replacement. Too dear, bye bye. With out it the car ran better, more power, more economical and as a poster said it's more peace of mind which in the long run equals value.

Considering getting it done on my latest car too as they are known to back fill the sump with diesel during a regen and thus run the risk of a run away, I'm not a fan of replacing engines so in certain cases DPF deletes are the only option. I've been studying the DPF in the latest car, regens every 300-340 miles, I find myself driving further to make sure a regen happens meaning more time on the road, more congestion, more fuel burnt, more wear and tear on the car and when you take that all into account it all adds up. There a plenty of other things out there causing way more air pollution then a car minus a DPF.

Sorry pal thats nonsense.

The dpf is a emmission control which keeps your diesel in under a co2 band. Remove it and its not in that band any more.
The high cost of repair is related to the ****ery that goes on to get your daysul into cheap tax. If you cant afford it you should have bought something else..

Also if you cant grasp the fact that the government put diesels into cheap tax to get people to buy them due to their low co2 emissions compared to petrol then i cant really say anymore to you. Basically the rate of tax has a huge bearing on rates of pollution, its used to reduce it.

mods feel free to close this thread, my question has been answered.

All valid points, I fully get you but at the same time from an economics point of view regardless of affordability, the cost of fixing and the knock problems they can cause with turbos, filling sumps ect.....
As the OP as pointed out we have diverted and he's got his answer!

The DPF filters particulates (i.e. soot), it has nothing to do with CO2 emissions...

The egr valve looks after that. Few cars going around without them too.

The EGR valve is for reducing NOx

Back from the garage, EGR valve fault. Getting a price on Monday. There goes my work bonus. Suppose it could be worse.

If your car has had the emissions update done then you should be able to get the EGR valve replaced FOC by Skoda.

Yes, this is a point. A friend with a Skoda Octavia had the emissions work done and then had another problem which involved changing two injectors. Skoda did it for free.

Thought id give an update. EGR valve was replaced with a new genuine part, not a generic one. Total cost (parts, labor, vat) was €885. My local garage did the work for me, not a skoda garage.
