Hi, Once a week the car has started doing this. It will run just slightly under 1000 revs, when you move off from stationary it will kick out smoke, a mixture of greyish and a little blue. You can smell smoke in the car when it is running like this. It will do this whether the car is cold or warm. I've taken it to 2 separate garages to get the DPF cleaned. Both have said it does not need doing as the levels are quite low. One advised to change the glow plugs (which I've done). No warning lights on dash (did have the DPF light a couple of times last year which led me to believe it was linked to that) but cleared up after a run. This issue will clear after a bit of a consistent run (regularly on the motorway so no real issues). It's approaching 190k and pretty much on original everything (clutch, turbo, DPF etc). The last garage I took it to advised to put some Lucas oil stabilizer in on the next oil change. Car has a full service every year and runs on Shell V Power (If that makes any difference). No loss of power, can be very very slightly lumpy when it is doing what ever it is doing. Any ideas what is causing this. Suspect a sensor failing or something? No idea really. The garage that checked DPF with VCDS said there were no other indicators.

Spot on mate thank you

I've replaced my Columbus unit (that died) with one of these, have the same problem, the trim is too wide around the head unit. Did you just find your old one or did you buy one - if so where from/which part? Cheers.

Cheers for response. I'd read this also. Trying a local car audio repair to see if they can sort.

A common fault then..

Evening, over the last few weeks i've been getting intermittent problems with the head unit. Occasionally when i've been driving with the unit on, turn the ignition off, get back to the car and start it, the head unit doesn't boot up. There are also no lights illuminated so appears to have no power. By itself it will then power on. I've tried resetting it (when it's been powered on) which has made no difference. This has happened more frequently and It seems to have died now, been driving today for over 2 hours and it hasn't come on. Any ideas? Thought maybe fuse but surely that either works or doesn't? Pic of the unit below

Sorted it, turns out I can't count..

Hi, I decided to upgrade the interior lights to LEDs. All went well until i got to the boot. I changed the drivers side and noticed the new bulb did not illuminate. I then realised none of them were working so suspected a blown fuse. Checked the forum and found it's fuse 15 that needs changing. I also saw that this was listed as a 7.5 amp. On mine it had 15. I've tried both and still not working. I've replaced the bulbs back with originals but still nothing. Any ideas? Thanks.

This thread may help

When my turbo went i had this whooshing sound when accelerating with cold engine, quickly followed by the engine management light. Once warmed up it seemed fine, just needed to stop the engine and start it again. I did try using turbo cleaner for a while - would put a bottle in when the tank was low and drive with high revs to try and clean it out. Worked for a bit but realistically you're just prolonging the inevitable . Think i paid around £620 for a Turbo (Fitted with new oil and feeds etc). Came with 2 yr warranty. Never had an issue with it then (until the gearbox died...)

Cheers guys for your help. Managed to change them today.

Evening all, Simple answer to this i'm sure.. I need to change the side lights on mk2 fl octavia. This has the xenon lights in - i've seen the videos on removing standard bulbs but not a guide on mine. Is it a similar process? From what i've seen the side light bulb is attached to a type of stork you just pull out? Is there anything i should be vary of removing this unit? Don't want this becoming expensive.

That's helpful thanks, i know little about cars and wouldn't have a clue where to start with what you've mentioned, but certainly food for thought. Think i may take it to a more specialized place to see if it's any of the things you've mentioned. I did have it re-gassed prior to this, they were really helpful. After an hour of whatever they were doing told me it's not working, don't know what's wrong with it. Good old Kwik Fit.

Yeah - £370 all in.
