hi all.
can any one tell me if they have like me, I have a 1.7 d 2012 astra j .
some time`s when the engine is sitting idel the engine give hunting sound and the rev`s go up and down slightly.
the other thing is, sometimes when I get out of the car there is a very strong smell of burning rubber (it`s not the tyres)
but the temp gauge don't go up.

Hi all, my Astra J is hunting on idle and has various error codes being displayed. I thought the hunting might be the SCV but the fuel consumption at idle doesn't match the other posts on this issue:

Astra J Hunting

I have the SVS error message and these are the codes that were pulled:

P037E - Glow Plug Module Feedback Low Voltage
B1517 - Battery Voltage
U0164 - Lost Communication With HVAC

Then I have a list of Door, wiper, light and washer

Hi

I'm posting this video incase anyone can help. I'm at my whitsend with this car 2011 cdti manual A20DTH. Argh well can't upload video, but when I start the car from cold any time of day or outside temperature it  hunts like a misfire, once it's warm it's as smooth as anything, there is also a faint whiff of diesel, like unburned, sweetish smell when it first starts.

Any ideas?
