Just bought 2011 1.6tdi Fabia Estate. All good except about every 150 miles it decides to increase it's idle rpm to 1000 and then if I have fan on blows fumes into car? Will do this for about next 30 miles then stops. I this Normal - surely not "it's part of regen bit again"

 

Its part of the regen bit.

Looking by your cars I see you must be happy to put up with this.

Any hints on how to minimise it's occurrence?

None of my cars have a DPF. Glad I never bought a modern diesel fitted with such an abomination. Can't advise further, sorry.

 

Someone will probably be along shortly with some constructive comments though...

Thanks.

 

Removing it is top of my list at moment

Welcome,

Regens maybe  normal, blowing fumes in car unacceptable and dangerous so best find the fault or have someone find it and repair.

 

Has the car had 'the fix' if so VW / Skoda can sort out the issue under their Warranty type thing they are doing for 24 months from The Fix being carried out.

The fix? Sorry not with you

I had a 1.6tdi for 5 years and never had any fumes getting into the cabin. I did notice a burning smell when parking up after a regen but this was only noticeable outside the car. This was due to the DPF being heated up to turn the trapped particulate matter to ash.

 

The fix is software update that will work the egr valve a lot harder. It is not compulsory. Because the 1.6tdi needs to warm up properly to complete the regeneration process it is not suited to repeated short journeys.

 

I got fed up of the regen business and chopped mine in for an older 1.9tdi.

 

Lots of info on the net and honest Johns if you do a EA189 engine search.

VW Group Euro 5 Diesel / TDI's  1.2, 1.6, 2.0 Scandal / Defeat Device removal/ new engine management likely to cause you trouble...

When buying a used car best find out if 'the fix' has been carried out, 

check the checker and see if outstanding, or check with a Main Dealer or Skoda Customer Services if it was carried out, 

if so then get your complaint in about the cars current condition, 

or maybe you want them doing 'The Fix' and sorting out a faulty engine putting fumes into the car.   Risky...

 

Bottom of this page tonight, or top of next page there are 2 Emissions threads, 

one with a new member that has had The fix and now problems.

Thanks,

Very useful,

Checked VIN through Skoda, Fix not done.

Only done 33K not sure what to do for best now.

wlil check link out.

May get performance / MPG remap, forget the fix and go from there.

The leak needs fixed first, and there must be a leak unless the fumes come in the rear hatch seal.

So if not it is in the engine compartment.

It's been back in 3 times - no fix.

It only does it when on "regen" ie when at 1000rpm on idle and never at that stage when I get it in to garage.

Always the same

 

Back in to who, and are you paying them, because they need to sort it out obviously, or find a man / woman that can.

All the gear and an idea and the training might help.

Back to dealer I bought it from. Had the issue within first fortnight. So no not paying them.

Am worried it dragging on a bit as is 2 weeks ish between going back in.etc.

The last time they said they'd replaced a hose - and hoped that was it - obviously not.

From what I've read this is not uncommon - The smell I mean.

Is it a Skoda or VW Group Dealership. and did nobody mention the Emissions Issue and 'The Fix'? 

Not VW/ Skoda, They seem happy enough to keep having it back. They are not charging and genuinely seem to want to fix it. Just don't know what is causing it.

Sorry to be gloomy but frequent regens suggests the DPF is getting full (of ash) and is near its end of life. Its a 6 year old car and only done 33k i.e. only just over 5k per year. So its been probably used for short shopping runs. Worst possible use case for DPF.

 

Its also very bad for the fragile EGR valves on these engines I believe which clog up. Maybe this has been changed at some point and has not been refitted well and is leaking exhaust fumes. Apparently its a pig to change and eyewateringly expensive.

 

I hate to think what a genuine replacement DPF would cost to have fitted.

 

Check the cars servicing/maintenance/warranty history with Skoda.

I'm totally new to this engine. And now totally confused as to what is up

I've not been told that the engine increasing idle speed to 1000rom is it regenerating. I just presume it is.

No DPF light has ever come on telling me to give it a "good run"etc.

How often should the engine "regenerate"?

I'm querying fumes in the car which everybody has said it is regen bit. Though this is only when stationary.

Does any body know how to tell if the engine has had the "FIx"

if you enter VIN number on Skoda website it just says the engine is one of those effected and to book it in. Not that is is fixed or not. Do not want to take it in as have heard of people getting auto fix without permission.

As this is second hand the previous owner is may not have told garage they sold it to if it had been done.

 

Only got experience of DPF on the 1.4 80BHP engine but they have a dash light go on to warn you, then you go faster on duel carriageway/motorway until the light goes off. This will take around ten/fifteen mins of 50mph +  driving so don't stop early as it won't clear and will just keep clogging until you go in to limp mode and need a forced regen.

 

The DPF also seems to get weaker or clog quicker with age and many owners tend to go to a diagnostic/repair tuning centre to get the offending filter opened up, remove the innards and rewarded and all the matching software deleted. I am not however, recommending you do this yourself. You cannot just remove the whole filter, box and all as it goes through a visual check at the annual MOT so the examiner will look to see if it is fitted and do a visual check for excessive fumes.

 

The removal will cost anything up to around £500 but that is a third the cost of a replacement filter or so it was. They will start to become more affordable as more people need to replace them due to lower, bulk manufacturing costs etc. 

Many thanks.

 

Sounds like a plan to me

I wonder if the reason the previous owner moved this car on was EGR failure and a new EGR has been fitted so it could be sold. I hope for you the EGR has been replaced at some time as otherwise likely to give trouble sooner or later.

 

If it has been replaced I suspect a joint somewhere is not properly sealed, particularly if a budget job and the seals were re-used.

 

Have you given the car a good long fast run to get everything properly hot as that may help too. I had a fumes issue, although not just when a regen was occurring, until I did a motorway trip of 50 miles each way. It has never occurred again.

 

If lots of short runs maybe regens every 150 miles or so are normal. Splitting the regen into several parts regularly is not good. What is your normal journey pattern? Too late to say now but modern diesels are not suitable for town work and mostly slow speed journeys.

The high tickover is definitely the regen. Feel the wings on the car after you stop when it's on it's high tickover and they should be hot to the touch. When my wife's is on a regen you do get some 'fumes' in the car. From what I read that's not unusual, although not great. My 2.0 I've never even noticed that do a regen! Hers does it every 3-4 weeks generally. As said above, if the DPF was failing you would have the warning light on. When hers starts a regen I just nip it up the motorway to clear, then it's fine for another few weeks - a pain, but other than that a great car! Just had the EGR replaced by the dealer (got a good portion of goodwill) too (no fix!) as they're prone to failure at around 6-7yrs / 60,000 miles.

 

I've read elsewhere in some VW forums on the 1.6TDi engine, that the earlier ones (like your and my wife's) are prone to 'rough' regens, and that updating the ECU software to a later version (non-fixed obviously!) makes this process a lot smoother - it's something I need to look more into.
