Hi,
We've had our Astra for 2 months now. It's 5 month old & was an ex demonstrator.
Weve noticed a random, intermittent noise on start up occasionally but not always. (It sounded like the starter motor wasn't dis-engaging at the right moment. We returned it to the dealership, & it was in for 16 days in total. It had them baffled too, but was fitted with a new starter motor & was kept in for testing. However on return, after a day or two the noise had returned.
The dealership had emailed a video of the noise to Vauxhall technichans. And we have now been told by both dealership & Vauxhall that the noise is NORMAL!!! And a "characteristic of the diesel model" Not anything mechanical!!!
Has Any one else had any problems??

Well, update... still ok.
No startup noise, even on a cold start.
I noticed also a slighly lower oil level, i could try that out.
What else i noticed is that if i push the engine a lot (rev up to 4000rpm for example) and do some quick miles, the cold start up noise isn't happening, until i drive it again very smooth for the next miles so it starts again.

Its the cam chain tensioner... It takes a few seconds to fill with oil... If left for a while especially after being a hot engine the oil drains out... When you start it up it takes a few seconds to fill and adjust... Nothing unusual here... Mine does it all the time... If after say 10 seconds the chain is still noisey then get it checked as the oil is either too thick or the chain has streached...
eg... listen to a 1.2 or 1.4 petrol corsa or astra... When the chain on them streaches they make a right noise...
That's exactly what it is , thought mine had stopped but did it again yesterday . The trouble with the tensioner doing this is that the chain will be loose while it pumps back up with oil pressure and this will cause a chain guide to snap then it will be disaster , they need to modify the tensioner with a stronger pre tension spring and all will be good , this is quite common on lots of other engines too , done two minis last week which now have modified tensioners .
Vauxhall are probably aware but wont admit until they have looked into it and start selling them .
Scares the life out of me when it happens as I know exactly what is happening in there , only 4k on mine too

Also went for the update (greece).
No change in the noise.
I spoke with the mechanic and they are aware of the noise, as all astra k diesels do them according to them.
Their official answer was that if Opel/Vauxhall doesn't release a technical fix they can't do anything about it.

I have a 2016 Zafira Tourer with the exact same problem. It reminds me of the old days when a car that was short of engine oil would 'knock' until the oil got around the engine then stop. It lasts up to ten seconds then stops. This happens completely at random. I've been told by a man at a vauxhall dealership that he saw a bulletin relating to this engine that stated a fault with software controlling oil pressure was the issue. I have a complaint going through with Sophie at black horse finance.

Hi Russjameslaw.aol.com,
I was the person who originally put the post on about the noise!
We're still no further forward with our car at all. Vauxhall have claimed all along the noise is "normal" !! And due to the fact we paid for our car outright we don't seem to have a leg to stand on. We spoke to an independent ombudsman who told us it was up to us to prove that the noise was NOT normal. Which would then cost us even more to do this.
We've resigned ourselves that the car it is what it is. We will in time change our car but will NEVER buy another Vauxhall again. They have treat us terribly, and it clearly isn't a normal noise when it turns other people's heads in car parks!!
Please keep me informed with how you get on with trading standards, I will watch this space.
Thank you 😊

The Vauxhall dealership where we bought our car from DIDNT think it was normal as originally they renewed the starter motor (thinking that's what the noise was)
It says it all, the noise ISNT normal, but Vauxhall will NOT do anything about it. They sent a field engineer from Edinburgh to see it.

Hi all,

I just found this thread during a google search while on a mission to get to the bottom of the same issue on my 1.6CDTI Mokka (65 plate)

A few months before my first service in late 2016 this same noise cropped up my car and it was mentioned to my dealership prior to the service and a 'no fault' came up. Admittedly after an oil change it was quiet for about a couple of weeks.

Fast forward to it's second service in October this year the noise/fault was bought to my dealerships attention again, for a second time it was 'no fault found'.

I was not happy with the findings so I contacted Vauxhall customer care who did some investigation and came back with the explanation from the technicians and that it was a characteristic of that engine. I've told them that I'm not settling for this and I'm still waiting for the findings in writing from Vauxhall. Surprise surprise I've not had it yet!

I get the feeling that I'll be pissing in the wind on this one but the way I see it is that this noise was not present on the car when I bought it new and that it's developed over time. My dealership have given me the 'suck it up buttercup' approach that's why I plan on taking this further.

Through some research I'm lead to believe that the first port of call is the finance provider which I'll be speaking to later today.

last reply to this was over 6 months back, has anyone else got any more news or managed to hold vauxhall to account?

Had mine in other day asking about the startup noise also on mine when it was getting clutch sorted

Dealer took me outside and started up a brand new insignia 1.6cdti. Exact same noise ! Apparently just how the engines were build taking time for oil to get on tensior

No more said after that.
