Sorry to sound numb, but just got the log book back for my newly purchased t25, it's states the engine number as DF, is this the same as a Dg engine as i've not heard much about these. are they generally good engines, what are the weaknesses etc.
Thanks

Re: DF/Dg whats the difference
there are quite a few differences...
and it's all to do with power, in that there is less of it with the DF
I could list the technicalities if you wish?
