Is 02 sensor located under the car itself and not located within engine bay on my Vauxhall Astra SE CDTi 108 60 plate.

My car is jerking after a while and goes into limp mode (no engine lights) and have reduced revs.

Its been getting worse progressively car is fine on short trips but any more than say 20 minutes it starts especially when car is going uphill and under pressure.

Code shows dpf partially blocked.

Was gonna try use some cleaner directly into the dpf via the o2 sensor.

Car needs a new shock too and handbrake not holding great, dont want to spend loads on it if I cant fix the engine issue which I presume is a blocked dpf.

Is it easy to take the whole dpf off and soak it or am I best off just trying to clean in situ

Hello all, I'm after some help.

I have a 2012 GTC  that I bought a few months back and had a new head unit professionally fitted. The car doesn't get used much and the (very old) battery went flat. It was jump started a few times with a power pack and there was nothing wromg with the stereo.

Then I fitted a new battery. The stereo was working right up to the battery change. Now it is as dead as a dodo as is the top display and the indicators no longer make a noise.

I have seen that others have had this same problem, but I am yet to see that anyone has fixed it.

Up to this point, I have disconnected the battery for 60 minutes and reconnected it. Tested all fuses in all 3 fuse boxes and scratched my head a lot.

It must be some sort of fuse or problem between the fuse box and the head unit/display.

Does anyone have any advice or suggestions please?

Hi, I have a 2013 Astra J GTC VXR stage 1. For the past few weeks i have been having acceleration issues where if i'm in 4th, 5th, 6th and i put my foot to the floor the car doesn't gain speed. the rev counter just jumps up and down and sounds like i'm revving the engine as if it's on neutral. I've taken the car to Vauxhall and they couldn't find an issue. Any suggestions and solutions would be appreciated.

Hi All, 
Just joined the group after owning a few Vauxhalls over the years.
first car 1.3 sr nova, 1.6 cavilier, 2.0 130 SRI etc.
I have now got myself an Astra, which i really enjoy driving, 
I`ve been doing some research and i think it is the last one of its model to be produced before moving onto the new shape in 2017


its a 2014 Astra SRI VX-Line CDTI S/S
VAUXHALL ASTRA SRI VX-LINE CDTI S/S - How Many Left?

Only changes are to the radio so far where i have changed for a full length Touch Screen and a stage 1 remap.

Happy to join this forum looking forward to learn from you all thanks

Hi, apologies if I'm breaking any rules by asking here. I've searched and searched and found very little info from Google or elsewhere. It may be that I'm not using the correct terms, this is why I'm hoping that someone might be able to assist me here.

Tldr (too long didn't read):
I have an electrical static noise coming from the dash passenger side. It sounds like when a speaker is loosely connected and it crackles.

Details:
The noise began after installing a vibe active sub. The sub already has a hi pass, so I used wago connectors to run a speaker wire direct to that using guides to understand where each wire should go. The install went well, the sub sounds nice. At first the noise was not apparent at all. One week after install I noticed the sound coming from what appears to be the passenger tweeter area.

When it occurs:
It doesn't happen when I blast the aircon, or turn the fans on full power.
It does happen when I'm travelling at over 25mph it gets louder and the tone changes slightly the faster I travel.
It doesn't happen when I rev the engine whilst stationary. It continues if I disengage the gear whilst travelling and release the accelerator.
This all indicates a vibration issue, or an electrical contact possibly touching an earth (I doubt this though as I've not interfered with such and the wago joins I'd tested and were well done). But the sound isn't a vibration sound, hard to tell of course whilst driving, but it really does sound like a badly connected speaker with the wire being moved around (I'm kinda hoping so one will know what I mean by that)

Things I've tried, I have tested for a good earth. Resistance is 0.5, that appears fine. I've disconnected the sub speaker wires (hi pass in from back of speaker out in stereo), no difference. I've disconnected the sub entirely, no difference. I've removed the passenger side tweeter, no difference.

My next test has to wait until the weekend, I'll dismount the glove box and get my wife to drive it whilst I listen to localise the sound. I may also go through the whole stereo removal process and double check everything I've done when fitting the sub wires.

Has anyone got any idea what this could be/experienced a similar issue?

Thanks in advance

Hi, I have just bought a vivaro to make into a camper, and bought the satnav genuine stereo to replace the standard stereo I even got the satnav wiring loom as it just plugs in to the main loom behind the stereo and the connectors on the 2 stereos are different. Once replacing the loom to the satnav one, I can have the satnav working when plugging in the big and little connector fine, but the other long thin connector, when I connect this in it makes the dash turn on without the key plugged in, and the stereo just has a flickering back light on the screen and it does not work at all. Without this connector I don't get the microphone working all though I know which wires they are in the long thin connector but there are 6 other wires in that connector 2 yellow 2 that look light pink and 2 that look white or light beige, the stereo does not turn on or off with the ignition, and the screen does not dim when the lights are turned on, does anyone have access to the wiring diagrams for the sat nav and standard stereo they could help with so I can swap pins in the connectors or what ever is needed to get it working as it was intended. Thanks in advance if you are able to help.
