Exhaust light on 2010 octavia

micks_address

Hi folks,
The exhaust light came on last week on my parents 2010 skoda octavia. 1.6 diesel. They probably aren't driving it enough on long enough journeys etc. I brought it for a brisk 30 minutes drive yesterday and the light went off. Reading the paper today and there's and add for stp dpf cleaner.

Anyone used it and is it any help?

They talked to local mechanic who reckons replacement filter be about 800 euro. Also suggested it could be removed altogether. If it was removed what are the consequences for emissions at nct etc?

Cheers
Mick

I Had a similar light come on my 2010 a4 tdi but it does get a lot of long distance driving. The exhaust emissions sensor was faulty. I got it replaced and its been fine ever since.

What did it cost ya? Have to get the same.

You need to get the fault code scanned to help identify the problem. Otherwise hit and hope part replacement can work out very expensive.

Dunno. It was covered under warranty, but apparently its cheap enough. I left it to the dealer and got a call about half hour later to say it was ready.

There are two lights one is specifically for the dpf that came on and went off with some brisk driving. The other is an exhaust system light. That's come on this morning and stayed on. He's going to get it scanned tomorrow

Hi guys
Father on to me this evening. Exhaust light on again. Brought back to local independent who's suggesting removing the dpf and reprogramming the ecu? Quoted 400 euro and guaranteed no issues with nct. His nearest skoda garage says it be two weeks before they can scan the car.

What's the cost to replace the dpf if it needs replacing?

Is the dpf removal a good way to go?

Cheers

What are the exact fault codes Micheal?

Thanks George you are exactly the man I wanted to talk to.

First light was the dpf light. That went off with a hard drive and hasn't come back on.

Second was the 'exhaust' system light and he has also had the squiggly pig tail light (coil? ) light on

I'd bring it as far as you only it's in sligo

What would you recommend the best course of action is?

Car seems to be driving fine, no loss of power no shudder or anything else that might suggest a problem

Thanks
Michael

Don't do anything until the codes are read.

Also he thinks if the light isn't on there's no point getting it scanned but it should hold the last few faults in the ecu?

George Dalton

Yes even if the lights aren't on the faults will still be stored in the ECU along with the freeze-frame data from when they occurred. Without knowing the codes it is impossible to say what the solution will be. Maybe someone else on here will be able to recommend someone who is good with these kind of issues in Sligo!

Thanks George what's your opinion on removing the dpf altogether? Is it a good/bad thing to do?

What sort of money would you be talking for a new dpf if it is gone?

Thanks

Aren't they going testing for Dpf's during nct tests within the next few years. Infairness you are not even sure if it is the dpf that's at fault you need to get the codes read by a decent mechanic and take it from there. Anything else is just guessing as all them warning lights cover a huge variety of different faults.

Yep I know a scan is the first port of call I'm just after a rough estimate of likely cost if the dpf needs replacing and also if the removal of dpf is a good or bad approach as I haven't a clue

Also apart from lights what are the symptoms of a dpf starting to go? Anything in the way the car drives etc be noticeable?
Thanks

Well if the nct do start testing for dpf's then removing it would be a very bad move as the car won't pass a test. You can get them cleaned as well as far as I know which would be a lot cheaper than a new one.

I'm no expert but if the DPF was knackered or blocked I'd expect to see reduced performance with the car such as going into limp home mode which basically means the car's computer senses a problem and reduces the performance of the car to protect it against damage.

Is there any difference in performance of the car?

It's performing better than ever

Anyway he will get it scanned so I'm not looking for a diagnosis here just opinions on cost etc if it needs doing...

Take her for a longer harder drive, 30 min in this weather won't get much temp in a modern diesel, so you might have cleared/regen'd the DPF but if it's not been driven hard regularly the exhaust could be stuffed with soot. Only cost you a bit of diesel and some fun when it starts burning the soot out.

Just an update on this. He got the car scanned and turned out to be a sensor. Got that replaced and all grand since
Thanks

Great result. Bring it for a brisk spin regularly to keep it sweet.
