Hi everyone,

I have emission issue.
“Emissions too high please check AdBlue.”
“Engine restart prevented in ... miles.“
Have you heard anyone having the same problem?

I know that Nick solved at least one of the reductant issues by pulling the connector block apart and cleaning the terminals,
it would be useful if the o/p has a list of any stored fault codes and an idea of what was looked at by the various garages.

Thanks for the mention guys, and for the message @Richie56. This is going to be difficult to really point in the general direction without actual fault code(s) extracted or read by the garages at the point they had the vehicle in and cleared the system. The warning on the dash is merely a warning for end user and doesn't give any detail.

The issue I've come across in my own experience was on my Euro 6 Insignia, when I first owned it had an intermittent Adblue issue which turned out to be poor/resistive connections to one or both of the NOx (Nitrogen Oxides) sensors bolted into the exhaust in front and behind the AdBlue catalyst. This fault was covered in a Vauxhall bulletin, but for Insignia only from what I can see, not Zafira-C.

There is another bulletin which IS listed for your Zafira - in which the testing of the AdBlue system confirms whether the correct amount of reductant is being provided at the injector into the exhaust. All this is going to require a fault code based diagnosis however.

I will say at this point that not all AdBlue is the same - the fluid should be labelled of ISO 22241-1 standard bare minimum (don't get putting anything in that's not labelled as such). However, even the ISO compliant stuff can be of mixed concentrations. Sometimes either weaker than the specified concentration of 32.5% urea, which can give symptoms of much higher AdBlue consumption. Worse still is reductant that is TOO concentrated - this stuff crystallises over time anyway, incorrect concentration can cause the lines and specifically injector to clog and faults like this to occur.

A quick, very rough test - if it stinks of cat piddle, it's probably slightly too strong. I used to use TPS's Quantum reductant, near odourless.

Hey mate I know this post is old. But I have a Zafira SRI CDTI 2015 with exactly the same problem this is what I’ve done :-

diagnosed and removed all error codes, still having error.

added Adblue, it’s full to the brim.

removed NOX sensor and cleaned it to no avail.

can you help and advise what was the solution to help you read love this, been looking everywhere on the forum to no avail.

I’ve had the faults read by a mobile diagnostic chap.. and he has reset all the errors. No management light just “high emissions check Adblue” on display im down to 15 miles preventing restart.

jusy wondering will the VX mechanic do the same as resetting the error codes or a software reset is different from VX mechanics?
Thank you

Software reset at dealers will be more than just clearing off all volatile memories.
It will actually reset the adblue counter back to where it should be & remove the message about the vehicle shutting down.
In 15 miles your cars about to breakdown.
I’d be on the phone to a VX dealer immediately to see if they can do a reset for you.

Did your mechanic give you a list of the faults before clearing them, clearing the faults don't make the problem go away,.. did he try doing a static regen, have you tried taking your car for a run on the motorway/dual carriageway to see if it will regen, maybe all the car needs is a run to allow the Adblue to work so it resets itself.
The Adblue system is self regulating so once filled the mileage countdown should auto reset, i would be inclined to take it for a run, but as your already aware that the countdown hits zero it wont restart and the only way to reset the counter is with a factory tool, or book your car into your local tuning company and have an Adblue delete done before its to late.

Thank you for your response guys, yes there was a few faults with regarding the Nox 2 sensor which we cleaned out and there is no error now. I did drive 70 miles an hour to Bedford and came back which still hasn’t obviously cleared the error message. That was the only fault I think you guys right I’ll be on the phone with a VX to do a soft reset with them.

just a thought 🤔
Is it possible to get a mechanic to remove the Adblue tank and check the sensor in the ad blue system.
 
#20 ·
I’d just get the reset done , no point spending more time mucking about with it , you’ve only got 15 miles before the engine shuts down.
Remember the actual reason for the high emissions message is because without the Adblue the emissions coming out of the exhaust will be higher according to how the car as been set up at the factory to recognise when the Adblue is about to run out.

The vehicle will still be registering an Adblue fault, this is why the countdown is still active, until its fixed it won't reset. Any mechanic can pull the sensor out and check the associated plug for corrosion, it will also be worth removing the adblue 'injector' and cleaning the opening in the exhaust where it fits, which i find to always be blocked by at least 90% from its correct size.

If any of this will cure your problem is anyone's guess, problem you got is the lack of remaining mileage to road test the car after any potential fix, i think you have left it to late.

Having similar issues with a 2yo/24k mile Insignia.

First the emissions warning light came on. Took it to a dealer who cleared the fault codes and topped up the AdBlue, (Was over half-full anyways). A mile up the road the warning came on again - so back it went.

Dealer cleared the faults (again) and advised it needed to go to a ‘technical centre’, the nearest of their’s being not too convenient for me I booked it in elsewhere.

Prior to dropping it off the emissions warning light was back on, followed by the “Service AdBlue” warning, then the “Engine Restart Not Possible In XXX Miles” warning.

Dealer #2 swapped out the Control Module, which only partly resolved the issue.

Last I heard they were ordering a replacement AdBlue tank. Been away for 4 weeks as dealer is awaiting parts from within the EU. 😕

Doesn’t fill you with a great deal of confidence.

I’ve spent a fortune, with no help from VX. Spent money on them telling me it’s a nox sensir 2 which I payed over 270, which they advised me this will fix the issue. After spending more money it hasn’t resolved the issue.
Now I’ve finally found someone to remove the Adblue system completely hopefully will clear any errors and will sell the car.

My advice stay clear from any VX cars with Adblue system.
 
#39 ·
Taken it to 2 garages who cannot remove the error of high emissions chek Adblue.

tried to disable the Adblue system to no avail.

I need advice, I’m afraid VX will-charge me an hour for not doing anything like they did before. They tried clearing faults and gave me a list as earlier discussions in which I have repaired all issues. Reading above.

Have you tried ringing back that vauxhall garage again that gave you the initial diagnostics, explain to them that they advised you to replace the wrong part and would they give you a discount on a second diagnostic?
Must be someon out there that could disable the adblue system and prog it out for you.
Anymore independent diesel specialists you could ring up?

My issue was resolved (touches wood) by replacing the entire Adblue reservoir. The problem was the sensor in the tank (which is integrated and can't be swapped out) wasn't registering a level, therefore the engine management assumed (wrongly) I was running without any Adblue in the tank. Hence the eventual appearance of "engine restart not possible in XXX miles" given you're not supposed to run it without the Adblue.

6 week wait to get the part at the dealer and mine was the first Ziggy they'd heard have this issue. (Lucky me eh?).

Don't think I'll be buying a diesel again - they're buggering the whole system trying to 'green' it up .:mad:
