Hi all,

Newbie here! Asking you guys for some advice. Right so I bought an Astra J 2015 1.6 CDTI in March. Full dealer service and low mileage 24000. All paperwork included. Seems all legit. Car drives pretty well, smooth start and idle and no strange engine sounds, only thing I can say is that I feel the car is labouring stightly during acceleration. But I have no evidence to back that up, it’s just a feeling.

So recently the ‘service vehicle soon’ light came up..I did what most people would do and booked it in for a service, not a dealer but a trusted friend of a friend local garage.

After the service was completed the SVS light was still on. So I phoned the garage telling them they needed to reset the light… this is when I found out the SVS light means something isn’t right but it’s not an engine management light… confusing!! So I booked it back in with them and asked them to run the diagnostics again, the issue was insufficient air flow relating to the EGR.

So today, I’ve just picked it up and the guy has said it needs a new EGR or the fault could be the ECU - a software or hardware issue. He said it’s likely to be the EGR… but the thing that isn’t sitting right with me is that he won’t know if it’s the old EGR until he fits the new one… this to me makes no sense, as if it’s a ECU issue I have then replaced the EGR for no reason and stuck with a bill for both EGR and ECU. He says this is an issue with Vauxhall this engine and the EGR…🤨

Surely there is a way to test them separately!! So that’s the story…. my question is, does this make sense? Or am I being flimflammed? I.e bent over the barrel…

Thanks for any help or advice in advance! 👍🏻
Andy

24k is really low mileage for a 6 year old diesel,
those engines are proving to regularly block the intake system with carbon at the best of times,
but running a diesel on short cold running journeys only makes the problem worse.
Before you change any parts i would get the intake system stripped and checked out

Thanks valer, I have removed the throttle body and the silver pipe (in your picture) to the rear as I was curious to see if it was caked it’s fully clear, I mean it’s clean! minimal deposits of carbon. Honestly that’s not the issue… where would I find the part in the last image?

Yeah since having the car I have placed 5000 miles on it since March, motorway driving to work and back about 40 miles. The DPF regeneration has run a cycle once since owning the car.

I have a basic understanding of how an engine works but what the mechanic said to me just doesn’t make sense!!

Thanks… would a home garage mechanic with a socket set be able to get to the cooler to check for blockages? or will it require specialist tools and lifting the car? Thanks again mate!
