Hi Folks, myself and my partner bought a corsa in July 2012 last year. The car was second hand previous owner was disabled and car was registered for disabled tax. Got a full service for the car back in November. Car is only drove through town twice a day to travel to work and various places...asda etc. All filters were replaced along with glowplugs at the service.

OK the problem...Missus was driving it home on Friday whent he car all of a sudden lossed power. Not even an engine management light on. Bit of smoke and she was able to get the car home. I went out on saturday morning tried to start the car and it wouldnt start. Left it for a couple of hours and went out again. Car chugged for a bit then fired up good bit of smoke out of the back of it. Tried to put my foot on the accelerator to rev the engine and no revs whatsoever then after a second of so the revs started to build up but wouldnt go over 1500rpm. So I turned to car off and started it again...chugging then started. Foot to the floor on the accelerator but this time the revs started to build up very very slowly until it got over 1500rpm then fully revved.

Stuck the car into reverse to drive it down the car park and as I put it into 1s same thing no revs but built up slowly got to about 1500rpm or more and then squeeled in 1st droped it into 2nd and again no revs in the early revs then picked up.

So took the car to a friend and its deff not the turbo because you can get a good speed (on a flat, dies on a hill) when your in 2000+rpm and no smoke belting out. the car actually takes off but in the early revs its just completely dead.

Friend checked the ERG valve and said it seemed clean that it wouldnt cause any issue. No warning light either. All filters were changed and the turbo is boosting. Friend unplugged the boost sensor and engine light came up and was completely dead when drove. So plugged it back in and he cleared the light (he has the disgnostic tools). Still happening! Has anyone had the same issue with theirs or anyone have any ideas of what it could be? The car hasnt even been through its 1st MOT yet and the dealer isnt going to touch it as the 6 month warranty ran out on 11th Jan.

The snag with these is that they don't like being driven round town - they need long hot runs on the motorway or the diesel particulate filter clogs up. Round town they never get hot enough to cleanse the system.

The thing to be wary of is that if the DPF is the problem then diesel can be dumped into the engine oil which can lead to catastrophic engine failure.

I'd take it to an independent diesel specialist - and once it's fixed make sure you don't use it round town. For that kind of driving you're better off with petrol.

An management light came on a while ago b4 Xmas and when we took it to the dealer he said it needed a good long run on the motorway to cleans the system but the light went off after a while and it seemed find but was still slow on the pickup and on occasion when the missus was drivin on a dual carriageway the car pulled back over reved a bit and then went on as normal. If the filter was blocked would it not show a management light?

On a lot of cars, the managment light won't come on until it's too late. Get the engine hot then get on a dual carriageway to get a nice long run with high revs. It'll heat the DPF up and start burning off all the soot and crap.

If you have a look at DPF problems online, you'll find hundreds of people in the same boat as you.

It's kind of a pointless device as any saving you think you make by buying a diesel with one fitted gets wiped out by unnecessary driving to keep it in good working order.

It's with my friend at the minute he was guna take off the cat and have a look at it but I think I'll just take it for a good hoak down the dual carriageway tonight and let you know if I get anywhere! Will anything else help like redex or anything? Yeah these diesel cars are the bane of my life! The amount of time spent servicing and fixing when things go wrong just ain't worth the money. The problem I'm seeing tho is that for the fact that the same car in petrol it's a few grand cheaper which for me is just plain robbery the amount of hassle you have with these new diesels when city drivin they should be cheaper!

Any ideas on how far a journey and average speed to give it a good clean? Or is it just a case of drive till it feels better?

When i had to sort one out, i got up to the speed limit and changed down a gear to bump the revs up. Distance, i haven't got a clue. It would depend on how bad the filter is which you won't know. I'd also make it a regular thing, as in once a fortnight to start, then once a month. Worked for me.

Thanks for the advice! I will give it a go later on there's a good long dual carriageway not too far from home also a motorway so will see how it pans out. Carriageway might be a bit safer if the power drops out! Will let you know of the results. Again thanks for posting!

Send it right through the rev range e.g. when joining a motorway push it up to high revs when accelerating before changing gear. You may see a lot of black smoke coming out but its pretty normal for this if the DPF is clogged. I drove for about 25 minutes at 70mph when this happened to one of our cars and it did it a world of good! Just make sure the engine is up to temp before thrashing it as pushing a cold engine hard wont do it any good
