 Hello

Hi all,

Last week while it was raining a lot of steam was coming up from the radiator, so I took it back to the independent I bought it from as it's still under warranty.

They said they couldn't find anything wrong, they did a 2 hour compression test and all came back fine. No coolant loss. And it's not let out steam since.

However a new problem has arose...

When the engine is warm, I get a lot of white smoke out the back that smells awful, a bit like burnt rubber or perhaps coolant.

What could this be? Googling suggests a head gasket, but it wasn't doing this before the compression test and its not overheating or losing oil/coolant.

EDIT: Astra J 1.6 petrol manual SRI

Hi, I have a Astra J 2.0 cdti 2011. I’m looking to buy a space saver wheel for it, can anyone confirm which braking system 2.0 cdti’s have? I think it might be the J60 brakes.
Cheers

Hi, does anyone know what terminals are in the X100 connector under the battery tray, (headlamp harness side male pins). I need to make some wiring to connect to the body loom to the PDC wiring I have so don't have to runs the wires to the boot. RS link to item if anyone has done this TIA.

Just been out to my car this morning and the service vehicle soon message came on and vehicle went into limp mode. tried half an hour later and same thing. this afternoon i was going to take it to local garage and see what they said but used spare key this time as was going to leave car with them and service vehicle soon came on then went off and car drove as normal. I have noticed my keyfob has been acting up recently and was wondering if low battery in keyfob could cause SVS.

Evening all...
Obviously owning an Astra has brought me here ?
Purchased a 2012 GTC 2.0 CDTi S/S back in May & I love it!
Got a few ideas for it so come here for some insights
First question; Are the rear quarter windows bonded or held in place with nuts?
Anyone remapped their car? Company locally called DK tuning saying they can give 200bhp plus improved mpg. Anyone else had an experience with a remap?

Future mods include;
Lowered
VXR/LTD edition front bumper
Respray in metallic red (currently gloss red)

All suggestions greatly appreciated

Hi folks, i got insignia 2.0 cdti 2009, and after some time i wanted to change ipc with mid level display for ipc with uplevel display. I read eeprom, changed my car vin and security code and all got working (odometer and no errors since ipc is from the same specs car like mine) but rev counter is staying at 0, although it does sweep at start. Is it some wiring issues or need more programing?
