Moin, we were at Mercedes today and have looked at some sprinters and have already selected 2-3 models. Now comes an exciting question 163 or 170 hp, i.e. OM651 or 654, which is the more durable engine? Both have the same torque, I would rather type the 2.2l instead of the 2l engine, but I think the 651ers have some diseases with water in the charging air cooler, at least the woman has the problem with the CLA X117 with 220cdi, which should be the same engine. in anticipation of your opinions, price up to 40,000 euros are both engines in it, so could choose the better one.
