I hope you’ve now got the answer! Do let us know what they found.

You should be able to match the glow plug type to the car’s registration number or Vehicle Identification Number (VIN) with Vauxhall/Opel’s parts system… though obviously you will have to speak to a main dealer or authorised parts supplier to accurately access the information. With any luck they WON’T be the same as mine, and might be cheaper!! (Be warned that the ebay or Amazon parts matching to car models might not be 100% accurate due to changes to exact parts fitted throughout the life of a car’s manufacture. I found taking out the fitted part and looking for a part number most efficient, though even then the currently available part had a different number!)

Good luck!

Hi Hassan,

If Google Translate is giving me the correct story, you are getting the SVS warning when the engine’s RPM gets quite high, and the car goes into “limp home mode”? You mention “the turbo going out of the circuit”, which is probably the “limp home mode” where the car feels like it has no power?

If I remember correctly, when I had a similar issue, it was the glow plugs which have a pressure sensor built in… One of them was sensing (incorrectly?) that there was too much pressure in one of the cylinders… The problem went away when I changed the plug(s) for the full priced “proper” ones rather than slightly cheaper ones I found on Amazon/Ebay, but that doesn’t mean that the “proper” ones can’t fail too!

I also had a similar issue when accelerating with higher rpm from quite low rpm and the error code was P228A Fuel Pressure Regulator. Presumably it felt it couldn’t deliver enough fuel for the requested RPM?? The engine was not quite up to temperature because it was on a short journey. The specific issue has not re-occurred so I haven’t looked any further.

Have you read the error codes when the problem happens? I currently keep a bluetooth OBDII device in the glove box, and read the codes with an android app, “Car Scanner Pro”. This might give a few clues, though it won’t physically change a sensor!

Let us know what you find.

Hi thanks for insight
My astra 2l cdti 62came up with svs then limp mode ,towed it home esp svs everything coming up
Thought it was injector as no1 really knew £500 for new injectors, no difference, went ok for about 4mile, would rev more than 3000 revs,limp mode then appears ok .i always thought it may be a sensor but no1 knew, been to a few diagnostic machines but no codes,booked in at vauxhall on thurs 21st after 10days of trying and trying,i hope it shows just a sensor

Hi there,

The O2 sensor on the exhaust was what was causing the issue in my Part Two investigation…. http://ukmotortalk.co.uk/2017/08/service-vehicle-soon-svs-fault-finding-in-vauxhall-astra-part-two/ … and prices certainly do vary quite dramatically. 200 euro is probably not far off if that includes fitting?

I don’t know for certain if the part will be exactly the same as on mine, but have a look at the part numbers mentioned on that Part Two page…. Ebay prices down around £60-70 (70-80 euro?) if you want to fit it yourself…

Good luck. Let us know how it goes!
