There are Jetta Diesels and Jetta TDI's, of the TDI's there is TDI, PD, and CR motors.
I think there is some confusion when people first sign up here at Fuley. I for one had to redo my car info for it to be in TDI as it was stuck in the regular jetta series. If there is a filter for different fuels that would be great and then you can lump all the jettas together. I only look at diesels as that is what trips my trigger.
Unless a mod is going to constantly go through and clean house, for those who mistakenly put their diesel jetta in the regular category, and place them correctly, there is no point to the two groups, because obviously people have a hard time understanding the difference.
I vote merge, put them both together. Members haven't done well seperating them anyway, and as was stated, this opens the door to people wanting a non-TDI diesel group, wanting a PD group, wanting a CR group etc. etc. the filter functions are capable of breaking up the diesel vs. fuel measurements. let people use them.
We could remove the TDI model designation, and push everyone back onto normal Jettas with the proper engine, and then in the future we could block someone from creating a TDI new model and it won't be available to everyone.
For custom car models, we approve them by hand, and one of us site admins accidentally approved "TDI" as a separate model at some point months ago.
I think we'll align everyone and fix this up next week sometime.
Merge them, there isn't an option for different engine types on other cars, why is the TDI an exception? Though I can see how it could mess up the average fuel economy of Jettas since the TDI's milege much higher than any of the gas engines, same could be said about the hybrid models.
