It seems that no-one really knows too much information about this stuff or what the process in the engine is.

Did the BMW dealership tell you that?

Wurth sells it and I have seen it at fuel stations - in bottles and also from a pump (can't remember where though).

With a little bit of searching you find ver nice technical explanations with pics:

Try looking on wikipedia. In short the fluid is sprayed into the exhaust gas in a Selective Cat (SCR) where the two work together to reduce NOx.

Appreciate this is an old thread but stumbled upon it and thought I would clarify. there is no requirement to got to dealer to have AdBlue filled up. You cannot let the tank run dry, otherwise aspects of the ECU need to be reset by the dealer and the car enters 'limp' mode.

I buy mine from Amazon and they deliver in 10L containers. Top it up on the drive and after about 30 kms of driving the tank registers the refill.

Reviving this diesel thread

I am in the market for a new car and looking at the new X3 or 5 series BMW. Now these have very nice driving diesel engines. The question is should i buy one with a diesel or petrol engine. I am worried about resale values and being banned from city centers.

What is the latest thinking on diesel since the VW scandal and the recalls that leave owners with problems with there engines?

avoid like the plague

there is also a separate thread about the topic.

Can you link to specific models?

The very fist X5s were built around the end of the last millennium....

The TDI motor in the lastest 2.0l Sharans exceeds Euro6 standards and is - AFAIK - Euro 6C compliant (it's of course not certified, yet).

So, it really, really, depends on make, model and year.

If you buy a petrol engine car now, be prepared for the whole Diesel-craze to repeat itself next year, when Euro 6C requires particle-filters for Petrol cars (Diesel cars have had them for a while).

Great. will look again for it. couldnt find anything searching with the words diesel and scandal

Thanks

I was thinking along the lines of X3 2.0 D or 528i. Also looking at a straightforward 320D for work and milage. So looking for a new car not a used one. Particulary interested in the new X3 but havent seen it yet other than on pictures.

If you can wait, wait until you can get one that will pass Euro 6C.

For the currently available models, that limits you (mostly) to the ones listed in the n-tv.de article (AFAIK, the Mercedes E220d and the E350d (but only the models that are leaving the factory right now - they had to stop selling them over the summer for this reason) also achieve or exceed Euro 6C).

I have a 1990 diesel VW T3 van, and have to get an emissions test yearly on top of the 'expertise'..I'm in Valais.NOt sure if this is age-related, but I know I have to do it. Just passed it in August, no drama, although I am embarrassed by the spluttering cloud I emit every time I start & am probably selling it soon as it's on my conscience daily ...

Thanks!

The Mercedes E T-model is also on my list. Good to know these engines are already Euro 6C. not decided yet on 4 or 6 cylinders

What does the C stand for in Euro 6C?
