Good evening fellow Astra owners.I`m seeking some help if anyone had the similiar problem with mine.I have an Astra J 1.7 CDTI 2014 with 131 BHP,72k miles on clock.
Everytime when I start driving,after a few minutes if stopping at the red light I can notice that my idle RPM is 1k instead of 800 and stalling.After start moving behind me it`s a huge smoke,so big that I can`t even see the car behind me.Also the consumption is increasing very badly,instead of ~80mpg in 4th gear dropping to ~25 and when idle from 0.2L/hour to 0.5L/hour.
Everything returns to normal,RPM and consumption when the engine is reaching 80-90 degrees.I have been to a mechanic,checked the car on diag and no errors showed up.He told me also that could be the DPF going in cleanmode but it`s normal to do this everyday?
Any help will be much appreciated and many thanks in advance.

Usually your revs increase on tick over and consumption increases if you car was having a Regen. Take your car out for a 30 min long run, just in case it's stuck within a continuous regen, caused by short journies. Also keep an eye on your dipstick oil level from cold. Make sure it doesn't rise too far. That's it it is a dpf issue.
It shouldn't be stalling during a regen, you'd only normally have a puff of smoke after one has completed, so maybe you have something else going on.
A decent diagnostic check would help. A good independent, does not need to be a vaux garage. A diesel specialist is better in my experience.
My car does a regen around once every two weeks or so.

Good morning.A short update regarding my problem.After a few days of writing this post,an error came up on dash,"diesel particle filter is full,continue driving".This is the first time.So I went on motorway and for about 30 minutes at 3k RPM.The error disappeared,next day everything fine,3rd day on my way to work regeneration starts again :)))
How my journeys are looking like,going to work 2 miles then back another 2 miles.
If I don't do any long runs my car practically is regenerating after every 4-5 miles.Is this normal?
I went again to my mechanic,he checked everything on diag,dpf pressure fine and no any other errors.
I'm really getting desperate, just bought the car a few months ago and I'm driving like 30 miles for 20£ diesel.The mechanic said that could be dpf sensor which when the engine is cold doesn't read information properly and I could try change it not being expensive.
Any other ideas?
Thank you

Completely the wrong car for you if you are only going to do 2 trips of 2 miles a day, you will almost inevitably have ongoing DPF problems. The car isn't even getting a chance to warm up.

Fully agree with koi on this one.
Your going to have constant issues with your DPF with those short journeys.
Do you have a push bike ?

Sounds like you are having ongoing dpf issues or it's partially blocked.
My car does one regen every two weeks, which lasts around 10 minutes to complete, once the cycle has started I let it complete.
Continuous short trips are not good for the dpf.
I'd take it to an independent diesel specialist if you are wanting to keep it. It's not just a case of taking it out fur a long trip, now and again. It's a case of adapting your driving style to accommodate the dpf filter. Once you have it sorted.
Diesels in cold weather can take up to 7 miles just to warm up from a cold start. Especially if you are out and about in traffic.

Sorry, but you bought the wrong car for your purposes (you should have bought a petrol).
Modern diesels with a DPF are only suitable for regular long journeys, but buyers get seduced by the promise of low fuel consumption.
I currently run an older diesel (no DPF), but my next car is likely to be a petrol.

I've recently relocated my workplace and now do four 1 mile journeys a day, but I don't have a DPF, otherwise I would be having issues too.

It will be the near side intercooler pipe, small split on the underside about 4 inches before the joint.

Well that’s my view
