Alright,

Looking to change gearbox oil in my 2011 2.0 CDTI. 
From Rustys list I've got that its an F40 box and needs 1.5 ltr oil.

Question is, which oil?

I can remember reading somewhere not to use the same oil as from the factory (too thin?) but I can't find the info again.

Grateful for any help.

Cheers.

Hello All,

Strange fault on my Astra, the outside temperature gauge fluctuates wildly goes from -2 to +17 in a short time then back to say +4 before moving again, the heat coming out of the vents is almost uncontrollable too no matter the setting on either side heater control

The external sensor was replaced last year following a front end rebuild after a shunt 

Any ideas please folks ?

I have searched high and low for an answer to this but cant find anything.

I have a 2013 2.0 CDTi S/S. Ever since I fitted my Android Headunit, about 18 months ago), the Eco button on the dashboard is constantly flashing (until I turn it off). I have changed the button but its still the same. Wiring all appears OK. Any ideas why this may be happening. Stop/ Start hasn't worked for about 6 months, not sure why as battery seems OK and I don't have any error messages stored.

Hello All and thank you for reading through this thread.

I have a GTC with the A14NET engine. My turbo is not building enough boost, I've done some testing that I'll list below, please advise on what to do next as I'm running out of ideas.

Using the OBD II and Torque Pro app I'm monitoring Turbo boost and Intake Manifold Pressure.
I have two solenoid valves as I thought this was the problem. 
With the solenoid connected to the wastegate, the car won't boost more than 4-5 PSI triggering a P0299 (UNDERBOOST)
Without the solenoid connected to the wastegate, the car will boost to 13-16 PSI for a couple of times until encountering a Service Vehicle Soon popup which essentially is a P0234 code (OVERBOOST) 
The MAX PSI for the intake manifold pressure registered was 27 PSI
The MAX PSI for the turbo boost registered was 16 PSI

I've also tried using a Manual Boost Controller (TURBO TEE) and "bypassing" the Solenoid. Same story, boosts a few times and then P0234 comes on limitting the boost to 4-5 PSI. 

Looking at the Workshop Manual it states the following: 
Use the scan tool and compare the manifold absolute pressure (MAP) Sensor parameter to the Boost Pressure Sensor parameter during a WOT acceleration. The readings should be within 20 kPa (2.9 PSI) of each other.

They are not within 2.9 PSI of each other. As mentioned above, max PSI for the Intake manifold pressure was 28 whilst Turbo boost PSI was 15-16 max.

I can hear my turbo spooling, I've adjusted the wastegate to open later but none of this worked. I've also checked the "nipple" inside the intake manifold and it's there. 

Can you please share your thoughts? I want to get it working properly but I don't want to buy a new turbo and end up having the same problem. A mechanic told me it's not the turbo whilst another mechanic told me it's the turbo. 

Many thanks!

I'm trying to find info on how often this is, but i keep finding conflicting info. Belt changes seem to say anywhere from 60k to 100k and chain changes say 60k/150k and the life of the car. Any idea on the real answer?

Hi all hope I'm posting in the correct place

I need to remove the A pillar interior cover on the passenger side of my car to fit a dashcam and a few other wires for my new stereo 

it doesn't have the airbag clip to flick out or a screw . I wondered if anyone knew a easy way to remove it before I yank it out and break it lol

Hi folks, picked up a cheap Astra J 1.4 a few weeks ago. Just got a car pass from Vauxhall so I'm looking forward to seeing what things I can turn on using opcom! 
First thing I did before I even drove it anywhere was enable the range and MPG  
Anyway, happy to be onboard, hopefully it'll be useful, I couldn't manage to get onto VXON!

Hey guys, new to the forum but not the astra. Had mine from new since 2013 1.7cdti. Stage 2 Remap, K&N awaiting new alloys and exhaust. Will upload photos at a later date, wondering if theres any other astra.members in aberdeen area.

Does a navi 950 intellilink system have the output for to fit a centre speaker. If it can be added is there a plug tied back somewhere on the loom or is it a matter of adding the pins and extra wires to the connector on the rear of the 950 unit.

Hi hi has anyone attempted  this mod
