I am considering buying a 2007/8 Mercedes-Benz Sprinter MWB as a work vehicle. I am mainly interested in the 315CDI model due to it being 110kw compared to the 311CDI (80kw) and 309CDI (65kw). Where I live there seems to be a lot more 309CDIs available. I know they all have the same 2.1L base engine but am wondering if it is just a case of upgrading the ecu program to get the extra horsepower or hardware changes are required. If anyone has any info on this it would be greatly appreciated.
Cheers
