Hi people, my beloved 2.4D (Bj 2009, Mj 2010 with 175 HP) has now reached almost 250k km. Except for a crack in the charging air hose at 223k km only wear parts have become due. During the last maintenance (free workshop, owner family is friends for 2 generations with our family – I have full confidence) oil was found in the cover of the belt drive, a slightly leaky Simmering right drive shaft and light transmission oil loss (manual transmission) . The first timing belt change was at about 150k km. Next ZR would not be due yet, I know, but on the occasion I would like to take this already. I consider to extend the package tooth belt + water pump to the climate compressor (KK), since occasionally a clinging of the same has led to engine damage. KK is still original, does not cause any problems. Meaningful or money waste? Greetings, Frank
