Can anyone let me know if a replacement Diesel Particulate Filter should be covered by the three year manufacturers warranty?

If so, can this work be undertaken by an Opel dealer in Spain on behalf of Vauxhall UK?

A quick response would be very welcome as I must drive 2000 km back to UK tomorrow.

Thanks you!

I bought an antara in feb and asked salesman if it was covered, they told me not!! What makes you think you need a new one?

Well since I drove down here two months ago the occasional illumination of the DPF icon (often triggered by short journeys) seems to have cleared until today. It is now accompanied by a chime which sounds every ten minutes or so. I have it booked into an Opel dealer first thing to check it out but I was just preparing myself for the worst as I'm scheduled to drive for 20 hours at midday. Is there a process whereby the mechanics can fix / clean the unit that you know of?

Dependant on level it is full they can force a regen, from what I have read it's more likely to be one of the pressure sensors which are before and after DPF, these are cheap and should be covered under warranty, fingers crossed

Thank you so much Andrew. Hope you're right. Can you direct me to a link with information about "forcing a regen" so that I can suggest they consider this? I'll post back when I get back to UK and let you know what happened.

I'm not exactly sure how they force a regen,but if they have a machine ,its quite easy.
Maybe a good run would sort it out? good luck

Don't think a "good run" is the best idea in this instance as I've put 7000 km on the clock in just 8 weeks. It's in with the experts today who I hope will get it ready for tonight as another 2000 km will be added getting back to UK. Thanks anyway.

The good news is that they now think it's a valve feeding the DPF and not the very expensive filter itself as they thought initially. The not such good news is that the replacement part has to be couriered from northern to southern Spain which means canceling my second ferry crossing. Just hoping Vauxhall's warranty covers Opel's invoice for this work when I get back to UK.

Quite possibly but could have been lost in translation. Does 80€ to 90€ sound about right for an EGR?

The egr valve re-directs all the unburnt fuel back through the engine (notthe best of ideas,but reduces emissions and road tax)and can get clogged up quite quickly.Suspect its not that.

Sound like the injector that adds extra fuel to the exhaust and filter to facilitate a regen.

The Antara doesn't have an injector to put fuel into the exhaust, the regens are completed by all 4 injectors adding a small amount of extra fuel on the exhaust stroke so it gets burnt on the filter face in the hot exhaust gas.
There is quite a common issue on exhaust sensors failing which causes sporadic DPF regeneration and warning lights. There are 2 sensors either side of the DPF itself which measure the pressure difference at each end, if the pressure in gets higher than out to a set level it tells the ECU the filter is getting clogged and this will then start a DPF regen. If one fails the ECU keeps thinking this is the case. I would guess it was a likely cause for the problem but we could be guessing all night.

The system that employs 2 sensors is quite a sophisticated one. I understood that the Antara's systemis hard stamped in the ECU - ie. regen every 520 miles (or so) ?

Yes your right, the ECU is programmed to regen every 500 miles give or take a few, but it still has the 2 sensors, if you ran the car on poor grade fuel for short journeys it could be possible to quickly clog the filter, so the sensors protect from this and will trigger a regen based on pressure difference.

SJG I think you're right. I got the car back ready for the trip back tomorrow with a service plus I think forcing a regen for 389 euros all inclusive. The Spanish for the regen is limpieza del filtro de particulares de escape I think. I speak fluent Spanish but not so hot on technical vocab. One thing I would like to ask is they have insisted that when I get back to the UK I go to Vauxhall because there is a fault on the Antara that is fixed free of charge which requires a part coming from Germany (at least Opel in Spain order it from Germany), but Vauxhall probably have it in stock. The number they have given me is 14-R-006. Any idea what this is? I got the idea it was the exhaust.

I had issues with the sensors when I got mine, it was doing a regen every 200 miles, they replaced the sensors and no trouble since.
What I do now, every month I add a small amount of fuel additive to help clean and loosen the carbon deposits, mine now only does a regen every 1500 miles
