I think one is for the auto and the other for manual and if I remember from another post the first one is for the auto but somebody may know better.
 
that post says 049s are for a manual? my auto has 049s fitted?what is different as my auto has always seemed to run ok?
 
There are those that will tell you that 30s and 49s have different spray patterns ,they do it makes no difference.
I have two 2003 .TD4s have one running 49s the other 30s, I defy anyone to tell the difference
The one running 30s returns slightly better mileage The one running,49s is a better tow car
