A200 and CLA 200 - Horrible engine/no acceleration at times

<p>Since the car came back from the first service, the car does not want to accelerate at times. The frequency of this experince becomes more as time goes on. Mercedes says the boost pressure sensor has failed and needed to be replaced.</p> <p>The fuel consumption is also horrific, 300-400 km on a tank</p> <p>The 200 engines have a big problem, but Mercedes dont/wont acknowledge that the 1.6 litre tubro engines are a huge mistake.</p>
