tow hitch and tdi question

Hello Briskodians

I come with a question , I have a 2004 silver octavia vrs acquired new back in 2004 funnily enough to replace a 2001 octavia vrs acquired ( bit of a pattern here) in 2001. I am now think it is time for a radical change and as it is 2008 thinking of getting , you'll never guess a 2008 octavia vrs.

i care a wee bit about the environment so am thinking of switching from petrol to diesel. I have heard that there have been some oil pump problems with the tdi pd 170 bhp engine - is that a very likely fault?

i also want to get a removable tow hitch and considering a brink 452000 removabel , and their website says the bumper cut ( ulp) is invisible on a standard 2008 octy but hey do not knw what ind of a chop job they woudl need ot do on the different bumper on a 2008 vrs.

Does nyone have experience of geting a discreet removable bumper fitted to a new Vrs.

My 04 came with a neat ( invisible ) removable factory fit bumper but ( i know i am in the presence of experts here so i better be careful) i think that the 2004 rear bumper was standard profile.

can anybody help me with my questions thanks in advance dod
