Hello all
I’m Paul Ellis, based in London, conducting research on behalf of the Japanese Ministry of Transport about how AdBlue and other SRC systems are used in the UK transport industry. The Japanese Government is considering introducing regulations similar to Euro 6. dieseldave has kindly allowed me to join this forum to carry out this research.
If you’d like to participate - and I’d be grateful if your would - I’ve pasted a short questionnaire below which should only take a few minutes to answer.
Please either reply here, or PM me. Just give me the question number, your answer, and any additional remarks.
The questionnaire is mostly to do with how drivers react to a low AdBlue warning. If this is not your responsibility and is always handled by Maintenance, please say so, and reply to the questions from that point of view. Names will not be passed on to the Japanese government or to any other body, and this research will not be used for any other purpose.
I’m on a fairly tight deadline: the research is due by the end of this week. If you’d like to know more about this, just ask. I’m happy to engage in discussion. Thank you, all.
