Hi all

In my service book it lists a "diesel additive" option but as yet it hasn't been done on mine, is it simply the BMW stealer pouring a cleaner into the fuel tank and if so what's the intention, EGR valve cleaning perhaps? When should this be done on a 2009 35d?

Thanks

Not required in the UK. US/Canadian models have a special 'Urea' tank for controlling Nitrogen Oxides emissions. As the Euro emission regs don't require it you don't need to worry. I think BMW now only produce a 'common' manual which makes reference to all sorts of things which may or may not be on your car.

The 35d is/was the only Diesel model available in the US, hence making mention of the diesel additive.

This Wikipedia article may provide more info..

Nitrous Oxide emissions? Are you sure????

Almost.....Nitrogen Oxides (NOx) - I thought it looked wrong when I typed it, but couldn't think why. I don't mean the laughing gas additive....

I was thinking in chemistry rather than convention terms - corrected!!
