you wanted ze diesel, ya?

u/DrunkenSailor89 2015 A6 Competition Oct 31 '24

Originally I wanted the S6, but that was out of price range at that moment, so I kinda did not "want" it😅 But I'm definitely going to get a petrol fired engine next year, this error on the second car in a row is a clear no to me for any diesel car...

Diesels are efficient and great for all that torque they offer, but with today’s restrictions and formalities, its more a headache than its worth. Plus if you go Audi, Quattro gives you all the grip you need anyways.

And they’re more fun to drive.

u/Confident_As_Hell Oct 31 '24

I drive a 2009 Volvo V50 1.6 diesel. It had to have the DPF replaced a year ago which was 1200€. It thankfully doesn't have AdBlue but it does have the PSA proprietary Eolys fluid. At least the fluid lasts 60k km and costs 250-300€ to refill. I think the new PSA diesels have Eolys plus AdBlue.

I love diesels but I don't think I would buy a newer one unless I needed a van.

u/_kermit_the_frog_ Nov 01 '24

They do, and their adblue system is defective with the injector nozzle getting clogged up all the time. Here in Europe they fail to assume that it's a factory problem and the customer has to pay for it's replacement. Most people I know just don't give a fuck and delete the system electronically. No more bullshit.

Diesel particle filters were something that were fiirst used on trucks for long distance travels. Why some moron decided that it would be great to put that on cars that are driven a few miles everyday is something that I can't quite understand. It was obvious what would happen. Clogged filters all the time, burnt cars on the side of the road, etc...

And so was the diesel engine slowly killed.

u/Confident_As_Hell Nov 01 '24

How much does it cost to get the AdBlue system fixed? Here in Finland they will make it a 1000€ fine to delete the DPF system. On semi trucks I think the fine will be tens of thousands

u/_kermit_the_frog_ Nov 01 '24 edited Nov 01 '24

In the independent workshop I work on, PSA (Peugeot, Citroen and Opel) quoted a client of mine of 1500€ plus VAT which in here it's 23% so 1845€ plus coding and labor.

I don't know the values of the fines but I guess that they would apprehend the car and force the owner to put it back as original and then go to a special inspection where they would measure the emissions value very precisely to make sure it's all good again. Here in Portugal it's called an "Inspecção B".

Beautiful.

Yet my 2010 A5 is still on its original DPF 14 years and 2002xxx km later

If you take care of it they can last !

1

u/_kermit_the_frog_ Nov 01 '24

Yes, of course. But I bet that you drive longer distances once in a while or at least have the concern of not interrupting a regen. Most people - especially older people - don't. They want the car to drive them from point A to point B.

These technologies are making the cars far less reliables.

u/No-Interaction-2165 Audi A5 Coupe 2010 (B8-8T) - 2.0 TDI Nov 01 '24 edited Nov 01 '24

True, I drive mostly long/moderately long distance on highway daily, and try to limit short trips as much as possible. It still does a lot of small trips weekly tho, sometimes below 2 km

I wish indeed I didn’t have to worry about it ! I’m closely monitoring the total oil ash volume, currently at 0.14L, once it’ll reach 0.17 the DPF will be toast but it progressed of 0.01 over a year and almost a half.

If you do city driving then indeed it’s not what you should drive

It’s a terrible system and the system gets clogged quite commonly. My adblue pump died last year and thankfully I was within warranty or I’d have had to pay out almost £2k as the pump and reservoir get replaced together

Definitely wouldn’t buy a car with adblue ever again

u/DrunkenSailor89 2015 A6 Competition Oct 31 '24

Yeah totally relatable, I won't buy a car with AdBlue ever again either....

u/Confident_As_Hell Oct 31 '24

The only new diesel vehicle I would consider buying is a van if I needed one. I love diesels but they just don't make sense in passenger cars nowadays, from monetary standpoint. Unless you drive like 50k km a year or something where the fuel savings are more than the increased maintenance costs

Modern diesels are too chocked up by emissions and too similar to gas engines.

Compression ratios have been down down for years.

u/kristmace 2021 e-tron 55 Sportback Oct 31 '24 edited Nov 01 '24

I've had a Skoda with AdBlue Diesel engine for 4 years. No issues at all. There's a filling station half a mile from my house with a dispenser. The car warns me when there's less than 1000 miles before it needs topping up (about every 6 months) and it costs about £10.

For that, it reduces the emissions meaning my vehicle tax is £30 a year instead of £190.

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

I guess it's like gambling if the system will be faulty or not 🤷🏼😅

Had the same problem couple of days ago, turns out Adblue was empty

u/DrunkenSailor89 2015 A6 Competition Oct 31 '24

The "AdBlue is empty" message popped up about two weeks ago, filled it up a few days later, so this can't be it 😅

u/_eg0_ 2021 S4 Avant Oct 31 '24

Could be crystalisation from filling up now blocking a valve or injector.

1

u/Tzunamitom Nov 01 '24

Fill it aaaaall the way. Usually about 20-25l, then the message should hopefully go away within 100km as the crystals are diluted!

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

According to the manual the AdBlue tank volume is around 13L if I'm not mistaken 🤷🏼

Ah maybe, I have a Q7 with an extended fuel tank so it may be bigger

You can mod your engine software, its a fraction of the costs to repair your adblue system.

It may just need adblue. I have a 2016 a6 tdi in the states. So far problem free, and get a notification that I need to add adblue in the next 1000 miles, or may not be able to start car.

As others have stated, there are tunes to bypass

u/andyjcw Nov 01 '24

closely followed by DPF.

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

True thing, both are good inventions emission wise, but not the way to implement it...

0

u/Kryptobasisti Nov 01 '24

Why? Unless you drive very short distances, DPFs don't clog that easily and there are 15 year-old cars that haven't had any DPF issues. Sure, fuel mileage and power is a bit worse, but that's a trade off for not having to breath cancerous diesel exhaust particles. If you don't mind them, I know an old diesel Mercedes that puts out pitch black smoke, if you want to take a breath from the exhaust pipe.

DPF is the best out of the three (>EGR & AdBlue).

u/andyjcw Nov 01 '24

lol.

u/Kryptobasisti Nov 01 '24 edited Nov 01 '24

A new DPF costs ~500-700 € which is less than new set of good tyres. If you can't afford that once in 10-15 years, then lol indeed. DPFs were way more expensive back in 2008 or so.

And please do go inhale that black soot from old diesel cars straight from the exhaust, it's good for you. I've once lived 150 meters from a high traffic road and the amount of black soot in the air ventilation filters was crazy. This isn't about climate change, it's about not making everyone around you (including asthmatics) inhale toxic particles.

u/Tjallaballa Oct 31 '24

It radically lowers NOx emissions. You know that the system is there when you buy a modern diesel, if that does not suit you, you should not buy a diesel. For the people around you its certainly not the worst system mankind invented.

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

I know 100% of what the system does and it's definitely a good idea but it's poorly implemented in my opinion :/ At least let me drive more than 1000km with a faulty system . My last car had this issue pop up when we were almost 1000km away on vacation .....

4

u/Secret-Assistance-10 Oct 31 '24

I'd argue it's a pretty good invention since it reduces the amount of NOX your car releases (it's a very cancerous particle).

3

u/DrunkenSailor89 2015 A6 Competition Oct 31 '24

You're totally right, the idea itself is good, but the way it's implemented is 'meh'😅

u/DrunkenSailor89 2015 A6 Competition Oct 31 '24

If I do this the german TÜV wouldn't let me drive it until the system is working as intended again 🥴 If I'm going to the TÜV with this error, it's the same thing as described in the first sentence :/

1

u/TjackJack Oct 31 '24

Really? In Sweden its allowed 🧐🧐

1

u/NATOuk Oct 31 '24

In the UK they have MOT inspections every year (once the car is over 3 years old), if they see there’s been any tampering with the emissions system they will fail the car and you can’t legally drive it until it’s put back to original spec

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

Exactly this is what the TÜV is like, except you only have to visit them every two years

1

u/TjackJack Nov 01 '24

I see. In sweden you have to visit every year for older cars. Its more for safety like brakes, safety lamps, airbags, shocks etc. If you did a stage 2 and had the AdBlue removed they dont really care aslong as your Co2 is within the limit. If you rebuilt the car and added like 300hp to the engine then yes you would have to go thru some other stuff aswell

1

u/Emotional-Start7994 2015 Audi A7 3.0 TDI Quattro Nov 01 '24

But how can they detect if the AdBlue system is disabled? It's a visual inspection so if there are no warning lights it'll pass.

2

u/NATOuk Nov 01 '24

I guess so, but they also do an emissions particulate test which I imagine would fail if the AdBlue wasn’t there

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

This!

1

u/Emotional-Start7994 2015 Audi A7 3.0 TDI Quattro Nov 03 '24

They do , but the NOx levels will still fall within the limits required for an MOT and still pass.

Some cars can't even have the emissions test carried out due to the rev limiter which stops them from revving the engine high enough for the machine. So in this case it is entirely a visual inspection. There is no way it can be detected using current testing methods.

1

u/NATOuk Nov 03 '24

That’s interesting, what’s the point of a NOx test if it can’t detect if the car’s emission system isn’t actually functioning ?

2

u/Emotional-Start7994 2015 Audi A7 3.0 TDI Quattro Nov 03 '24

The test is simply to check if they are within limits. Even without the AdBlue system they most likely are, and thus it passes. It does seem pointless, especially on newer cars.

I believe the NOx limit for the MOT is 0.25 gm/km, which is the exact same as required for a Euro 4 compliant engine (which of course does not have AdBlue).

Euro 6 compliance requires a NOx limit of 0.08 gm/km, so it may not meet this limit but will still meet the MOT limit.

1

u/NATOuk Nov 03 '24

That’s interesting. My Audi diesel was one of the last before the AdBlue came in and I assumed the test would look for the required NOx levels for the engine type? Clearly not!

I did ask a mechanic whether I should have got a Euro 6 model (only a year older than mine) and he emphatically shook his head and said I have the better option. Apparently simpler, less likely to fail. I’ll take that as a win

u/Charming_CiscoNerd Oct 31 '24

Good post but does this meaning you have to add adblue?

Or is something broken?

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

I'm pretty sure something is broken, because it's not the message where it tells me to fill up AdBlue, this message popped up around two weeks ago which is like "bla bla refill AdBlue, 2400km range" I did this pretty soon after it showed up so there is for enough AdBlue in the tank 🤷🏼😐

1

u/Charming_CiscoNerd Nov 01 '24

Ive had this issue, Audi main dealer filled my ad blue up, then two weeks later, it says fill up.

I had an Audi service, and they asked anything else wrong, I said yes I have warranty and the ad blue message is up. This was a shock to them, probably because of the costs if they needed to replace it.

They looked at it, came back said it’s fine, and I recall they reset the Adblue counter whatever that means.

It’s worth getting a diagnostic test

Neutralising harmful exhaust emissions, definitely the worst system mankind ever invented.

It's cheap and lasts for ages, the system warns you to top it up with plenty of notice. If your car won't go, that's on you not AdBlue.

1

u/DrunkenSailor89 2015 A6 Competition Nov 01 '24

I'm fully aware of what this system does, and it's generally a good invention no doubt. My point was more about the way it's implemented, at least let me drive an unlimited range if something is wrong with this system, I mean if the catalytic converter (cc) has a problem your car doesn't tell you "Only X-km left before you can't start the car anymore" and the cc does neutralise harmful exhaust gases as well. 🤷🏼

Kurzes Update. Audi meinte die müssen alles tauschen und würde 2000-2500 Euro kosten.

Auslesung zuhause meinte Steuergerät also haben wir das ausgebaut und an so ne Firma geschickt die das Ding für 285 Euro repariert hat (war ein Wasserschaden). Steuergerät kam nach einer Woche wieder, wieder eingebaut (ist easy no Problem) und seitdem alles gut.

Einfach nur 1/10 von dem bezahlt was Audi quasi wollte. Schon enttäuschend.

I have a few cars with Adblue systems and the big problem for me is not the tech or that it fails its that there is so little support from the industry.
