2001 Mercedes w210 e320

Check engine light was on for a few weeks.  Checked error with OBD reader bought on Amazon for $9. Error was P0400 exhaust gas recirculation flow. Checked around the valve and after 16 years, EGR valve tube was cracked. Luckily it was near the valve hence chopped a bit and reconnect. Eventually I'll need a new tube because the tube was brittle.
