Hello everyone, I'm new to this. I have a 2015 Peugeot 208 1.6 diesel. When I take my foot off the brake while starting, before I even touch the gas pedal, I hear a thud, as if someone has hit me from behind. This doesn't happen all the time, but it's gotten worse. The car has 100,000 km and the transmission fluid hasn't been changed. I suspect it would happen constantly if it were a pressure plate issue. I'm looking forward to your help and suggestions. Thanks in advance.
