Hi all, I'm looking to buy a Mercedes B class sport, most seem to be 180ds. I'm looking at 2012 to 14 age manuals, but in getting really confused with the engines. Wikipedia and other sources suggest there is a 1.5 and a 1.8 variant but I'm struggling to understand how to tell the difference (in for sale adverts). Auto Trader shows displacement but not sure if it's accurate. So I guess question 1 is when did they change it / what models is related to each engine? How do I tell? Second is, which do I want? They seem to have similar outputs. I may consider adding a tuning box or a remap at a later date too. The titles of some that I've saved so far have either cdi or cdi blue efficiency. Third question is there are a few 200d in budget. Are these mechanically different to the 180d or can they be remapped to 200 levels? First Mercedes so thanks for any input you can provide!
