Hello 

I get a SvS fault when I start the car. I used a multimeter to measure the resistance of the glow plugs and one was not working, so I am betting the SvS is a faulty glow plug.

Will the electric current overload the 3 working ones, so they will fail soon? So I need to replace all of them asap? And will a car with 3/4 working glow plugs start fine in really cold weather like -15 Celsius?

Regards

I have a 1.4 na with 40k on the clock, today on the way home it was  making this whirring type sound at a standstill , with a slight rev the sound will go, the sound seems to be coming from the drivers side of the engine bay, belt seems fine, steering is fine. Any ideas?

Hi all
I am quite new at this forum, so this is my first poost and I hope not break any rules.
In the last days I noticed my Astra is making some weird noise. It seems there is some broken piece inside and quite often creates this `crack` sound. 
The car is an ASTRA J 1.4 turbo 140cv with 67.000km
I want able to attach the video, but I share a google drive link where you can watch and hear the noise.

I have a 2013 Astra 1.4i and the EML light is constantly on, the garage has reset the light but it immediately comes back on and also gives the code P0171.
