Hello together, I have a problem with my smart, has power loss while driving. Suddenly gets slow and nothing goes more. Grade no more than 30 km/h. No more gas on either automatic or by switching down via Tiptronic. Motor light does not work. Have now read out the error memory itself with interface of car soft müller. Shows now P0238: Turbocharger charging sensor A circuit too high. What could that be? Drive daily highway 32 km one way. Particle filter too? Greeting Dirk
