Hi @ll Yesterday I got our new V60 D5 switch with Heico chip from the dealer. after exactly 83 km quiet drive (not over 2500 u/min and never full gas) came the message “MOTOR system maintenance urgent” Volvo Assistance called – 1.5 h waited – Adac has read out the error memory with the result : P0049, P0236, P0299 in words : Turbocharger Maximum speed exceeded, intake pressure too low, charging pressure sensor faulty. Presumably : The car “don’t know” that it was chipped ??? and therefore has wrong values ? will drive around the corner at me on Monday. At other great venture the errors will be fixed and will not come back. Greeting Cowman: From yesterday V60 driver
