This does demonstrate and (it is certainly not the first similar case Iíve come across recently) that thereís some unprofessionalism out there within the motor industry still, and that motorists, more especially drivers who donít deal with the haulage industry, who will probably get caught out, either by not realising the importance of ensuring that itís kept topped up (mainly due to them not being told by the garage), or worse, suggesting that car AdBlue is either better than, or different from, any other AdBlue. Interestingly he found that just five litres was needed to take the AdBlue dashboard warning light off!
I heard of another case recently, where a BMW owner was apparently told that manufacturer warranty claims on his car might be affected if he decided not to use the BMW branded AdBlue! Dear oh dear. Bad practice, I feel, and illegal under EU Law, I would think.
Anyway enough of my rant ñ hopefully better experiences are to come for drivers, with your magazine’s help!

I am not at all surprised at the two examples that you gave, which frankly smells of naked commercial greed. If not dispersed to the dealers and salespeople as “company policy”, then probably suggested by dealer management. Dealers want owners to have their AdBlue to be topped up at service time, which would work effectively if the tank capacity was large enough to last between services, without any warning lights appearing ñ much as is the case with Eolys fluid for some diesel particulate filters (DPFs). That is sadly not the case. I have noticed that some Audi models come with only a 12-litre capacity AdBlue tank, with a 24-litre tank optionally available.
The system appears set up to facilitate a nice profit for dealers, and to keep owners enough in the dark to ensure that this is precisely the case. The BMW BluePerformance brochure does actually tell owners how to refill with AdBlue themselves, and it also clearly specifies ISO 22241 and makes no effort to suggest that you have to buy it from your BMW dealer. I’m not sure how much of this is in the ownerís manual, as I can’t seem to source a current one to view. But we have to accept that too many owners don’t even bother to look at their manuals, and in some ways if they get stung, it is rather down to them. But to send a new owner off without mentioning AdBlue really is totally unacceptable ñ is it not in the handover process, or is it just skipped over by sales people?

Analysis of the VW defeat device code, and witness statements from the USA EPA/Carb legal trials show the Adblue dosage is purposely capped and underdosed simply to conserve the limited capacity of the Adblue tank, other evidence includes the recent submission by VW of collusion between manufacturers to misrepresent the running costs of a diesel car, a legal deposition in the USA showed that a VW Tiguan required a litre of Adblue every 68 miles of driving when correctly calibrated to meet USA emission requirements. the cost of replenishing Adblue at such high consumption levels practically nullified any mpg advantages of the diesel car, an unpleasant fact that commercial interests do not wish to be public knowledge.
