Hello, today I saw that my Astra k 1.6 cdti 2016 needs to be recalled, when I called local dealership they told me that it has something to do with "emissions ". They didn't tell me more about, only thing I know is that it has something to do with updating software (ECU I guess). Did anyone else have same recall as I do? Will this affect engine performance or fuel fuel consumption? Does anyone know anything about this recall? I tried finding more about it on forums but I only found this thread https://www.astrakforums.co.uk/viewtopic.php?t=6033 . Thanks in advance.

I think it's to do with the Nox emissions meeting their original claimed targets. May have been ordered to do so.
As you'll probably know VW were found to have introduced a cheat device/software to lower emissions during testing. Found out and fined.
From what I've read on Skoda forums after people have gone in for their ECU updates their cars are less fuel efficient, no suprise there then.
There's now a lot of legal firms taking on other manufacturers Inc vaux about their originally stated emisson results. So only time will tell if vaux would have to trump up potentially millions to previous owners.

From what i read about the VW recall, they reprogrammed the ECU to meet the stated emissions, but in doing so, the cars "lost" some horsepower.

I wonder if vauxhall will also have to take away horsepower to get their software to stay within the stated emissions figures.

If so, we should really make a big stink out of it, i feel my current 110 horsepower is about enough for what i do with the car, but if they took away some horses and some torque's it would make the car less suitable for what i bought it, to do.

A bit like buying the 1.6 petrol, and then they updated the firmware, and suddenly you only have a "1.4" engine in the car.

Yeah, if that's the case I guess no firmware update for me. Also, sincwe drive same car same year, did you also recieve an email about recall? @astraowner

I think the VW engines are doing more regens too, so hitting you harder within the wallet. I'd expect Vauxhalls would do the same. Why reprogram them otherwise?

I certainly won't be taking mine in if asked to , as long as it passes the MOT that's fine.
You've got the hassle of taking it in , then picking it up , dropping in a fast car and then taking back a slower car…..no thanks.
VX arnt fiddling with my ecu at all.

I saw a few technical talks about the VW scandal, and what they actually did, and to me it sounded like they mostly disabled the adblue system, when it did not detect that it was in the NEDC test cycle.

This made emissions a lot worse because, the adblue converts some of the harmful stuff to less harmful stuff, and honestly it did not make a lot of sense, the only benefit from this, was that people saved a bit of money on the adblue, but adblue is not that expensive, and people buying a car that uses adblue, know they need to add adblue.

In my country it is the "DVLA" that sends the notices for recall's as the car manufacturer don't know who owns the affected cars.

They also usually require the manufacturer to report to the "DVLA" when the fix has been carried out. Especially if it is related to emissions or there is a risk of fire, for example.

So, if i go to get the MOT'ed, the MOT station will be unable to enter the MOT status into the system if it has active recalls.

It's the same if i owe money for road tax, insurance, have unpaid fines relating to the car. It is simply not possible to do the MOT and have it entered into the system until i sort out the problem.

But yes....I would not want to take it to vauxhall just to have them take away 10 horses and 50 torques to meet the emissions they promised they would.

In such a case, they should be forced to pay me, for the valueloss of having a less powerful car. Possibly it would also have to have it's registration details updated, a car is rated for a certain trailer hitch weight, based on for example engine size, so if it suddenly has less oooomph, then it will maybe only be allowed to pull a 1200 kg trailer, instead of a 1400 kg trailer.

This could be very problematic for someone that has a caravan that weighs in at 1350 for example, suddenly this guy has a caravan that the car they sold him, to pull the caravan, is suddenly not allowed to anymore.

To be honest, they should be forced to buy back the cars off of people that wanted this option, when their car suddenly does not have the specs, it was sold with.

I've also read since the VW/Skoda updates were carried out, some of the owners had complained about increased mpg & more frequent regens. So I think it effects more than the adblue system with their cheating software.
Vauxhall/Stellantis may be in for a shock too if the layers get their way, could owe millions out within compensation to their customers too. May take up to 10 years to find out though. I think something has gone on, as they've been ordered to recall their vehicles to adjust their emissions. Maybe one day we'll find out, within the mean time thousands of vauxhall drivers have lodged group claims against them through the various solicitors out there on a no win no fee basis.
Although Vauxhall at the moment are denying that they ever introduced any cheating software. I'll take that with a pinch of salt though. To make a claim you need a copy of your original bill of sale or get hold of one from your original supplying dealer, whether it be a new or used Vauxhall diesel. As yet I've not put a claim in.

Following up, here's the relevant page from the DVSA report:

Vauxhall Astra SRi CDTI

4.66 The testing results of the Astra raised concerns in terms of NOx.

4.67 Initial tests showed that the Astra failed the laboratory NEDC (cold and hot) tests. We arranged for a second vehicle to be tested to check that it wasn't an issue with that specific vehicle. Although the second vehicle passed the NEDC (cold) test, it did exhibit significantly increased NOx when running the NEDC (hot) test.

4.68 When we shared the results with Vauxhall they offered a number of possible explanations for the results, none of which were convincing.

4.69 We were surprised that NOx emissions had increased to more than twice the legislative limit when tested on the NEDC (hot) cycle in a condition where the vehicle would not know it was under test. This is a standard cycle in which the vehicle is not driven aggressively. WLTP (track) and RDE test results also showed high NOx. Vauxhall explained that they had not conducted a WLTP (track) cycle test for this vehicle so were unable to comment but they had carried out RDE tests and found similar results to MSU.

4.70 Vauxhall highlighted that the engines for these vehicles had been developed some time ago (2013/14) and were used in the previous generation Astra. Since that time, expectations have changed and all of their newer models contain an SCR system, rather than just LNT. Therefore, the high NOx on the RDE test could be expected from a vehicle which had no SCR system.

4.71 On the request of the manufacturer, the vehicle was retested. Vauxhall engineers inspected the vehicle and downloaded codes/data from the ECU. The preconditioning and DPF regeneration were both carried out the same day. The vehicle was tested the next day; NEDC (cold) followed by NEDC (hot).

4.72 Vauxhall shared with us that they are currently working with the German approval authority, KBA, to develop a recalibration of the emissions control system to improve emissions performance. Vauxhall expect the recalibrated software to reduce NOx emissions in the real world by about 50%.

4.73 Approval of the modification is still pending. Following approval, Vauxhall will apply the modification to all vehicles across Europe, including the 13,864 vehicles in the UK. Vauxhall will offer this upgrade to UK customers via direct mail. Vauxhall have informed us that the upgrade will be free of charge for customers and will take approximately 30 minutes.

4.74 It was agreed with Vauxhall that we will test a recalibrated vehicle to validate whether emissions in the real world are reduced. We expect to publish the results in the next report.
"LNT" and "SCR" explained:

Lean NOx Trap (LNT)

Unlike a petrol engine, a diesel engine's exhaust is 'lean' - a term meaning it has excess oxygen present. As a result, a standard catalyst cannot convert NOx emissions. A lean NOx trap is a device which looks similar to a standard catalyst, but which acts as a molecular sponge, chemically trapping NOx emissions (by adsorption) rather than converting them. The amount of NOxa trap can hold is dependent on its temperature. The optimum temperature window is typically around 250-450°C. However, once the trap is full, it can't adsorb any more NOx. The trap must therefore be periodically 'purged' by briefly creating 'rich' conditions (excess fuel) in the exhaust. When this happens the trap releases and simultaneously converts the NOx to nitrogen and water vapour. The frequency with which this happens will depend on the system and the driving conditions, but it is typically several times an hour.
Selective Catalytic Reduction (SCR)

SCR is an alternative catalyst system that is able to convert NOx even under 'lean' exhaust gas conditions. The reaction takes place with ammonia (typically supplied as AdBlue) in the presence of a catalyst, either oxides of base metals (such as vanadium, molybdenum and tungsten), zeolites, or various precious metals. To be efficient, the SCR must be at its nominal operating temperature (350-450 °C) and it can reduce NOx emissions by up to 95%. Critically, unlike the other systems described here, SCR relies on a consumable reagent (to provide the ammonia) and only reduces emissions whilst the catalyst is being supplied or "dosed" with this reagent. As a result, regulations require a visible and audible driver warning when reagent levels are low and that vehicle performance is restricted or engine restart is prevented if the driver fails to refill the system

The temperature of the SCR is determined primarily by the exhaust gas. Therefore, the placement of the SCR in relation to the engine and the engine's duty cycle are critical with respect to the SCR's performance. The SCR canister is relatively large. In addition to the SCR, the following are also required:

• AdBlue tank - the AdBlue dosing rate will vary by engine and vehicle but this tank will be sized to avoid vehicle owners having to refill too frequently. The tank also contains heaters and sensors.
• A dosing pump - to pump the AdBlue from the tank into the exhaust pipe just before the SCR.
• A control module - to control the amount of AdBlue added.
• Pre and post SCR NOx sensors - to ensure that the SCR system is operating correctly.

Although readily available, the main design constraint is the amount of space needed for the installation.
If the modification from Vauxhall only takes 30 minutes then that's going to be engine ECU firmware update, not AdBlue.
Based on this post and article, Opel is not following emission norms, so I guess that's main reason for this recall, luckly for me in my country I can register and insure car even if it has active recalls, so I doubt I'll go and get my ECU updated.

I have not received any recall yet.

In my, very socialist country, everything, government related is very slow and very ineffective, so it sometimes takes months to have this sent out though.

I had the clutch/brake recall stage 2 done, 2 years ago, so maybe they did the firmware upgrade there, without my knowledge, and i dont need it ?

At that time i had an Opel app that i could enter my VIN into, and it told me that there was an active recall for the car. But offcourse, opel, being opel, they took away that option, so the app became useless.

And unlike in the UK, we don't have a website that we can enter a VIN into and get told if there are active recalls for a car, like it seems you have in the UK

It says

We do not have a record of an outstanding recall for the VIN and Make searched. You should follow the advice provided by the vehicle manufacturer in the table below.

So either they dont have any recall's or they dont have any records for recall's for my left hand drive Opel :D (Tried both with vauxhall and opel as make)

I'll just have to wait and see i guess ;)

Tbh AO, I just tried a generic "astra K" search on the gov.uk site and the only recalls I managed to bring up were the main ones we all know about on here plus a couple regarding seat back welding problems, brake pipes being installed incorrectly and rear wheel bolts been done-up wrong.

<cynic mode ON>I should imagine that if Vauxhall "play the game" with the government and agree to get the cars sorted before anybody starts to make a big deal of it, they'll prolly allow them to do it off their own bat :evil: <cynic mode OFF>

Hi

So i have just received the recall letter here in Denmark

It says that the quality control at Opel has found that on some cars, mine included, the NoX emissions can be lowered substancially with a software update.

They call it factory campaign 21-R-054

It does not say that failure to get the software updated is a MOT fail.

Has anyone heard if this update will take away horsepower from the car, like it did on the Volkswagens ?

Still dont think i will have this done, if there is a risk it makes the car slower.

It would be interesting to see if anybody has actually asked Vaux/Opel whether the "update" would affect the cars performance figures...........I could imagine rather a long wait forra reply :lol: :lol:

I for one would never trust a "yeah, the car will be the same, just with lower NoX emissions". from Opel/Vauxhall. They would never admit that. (The just recently admitted that their chains that has been rattling for years, have a problem with the tensioner.)

I wish someone with access to a performance test setup would test the car, go get the firmware updated and test it again right after.

It seems almost incredible if Opel/Vauxhall will be able to do the NoX fix, without loosing any horses, when volkswagen was unable.

My car "only" has 110hp as standard, i am not willing to give up 5-10 horses....Atleast not without some sort of compensation.

If i get it updated, and then it is revealed that the engine performance has been degraded, it would be worth less money as well, when i go to sell it.

Your´s is a diesel unit. It would be 100% doable to bring the unit up to 136bhp level without any circumstances at MOT.
Sure, that would probably only need a reprogrammed ECU, that has a map with higher turbo pressure.

But...When i then go to vauxhall for this emissions recall, they would just overwrite the "tune"

110 is fine, but if they take away some of those, i am not happy. :)
