Low power at startup
I have a c270 with a strange problem. On a cold start the power is very low. Seems that the turbo does not kick in. If I drive for a few km's, switch the car off and restart, everything is back to normal. It requires a restart to correct the problem. I have tried driving for a long distance and the low power issue never corrects until you restart. It seems the vehicle needs to warm up and then needs a restart. Any ideas out there. I did have the engine logs checked. No engine errors reported but some messages relating to the gearbox. It's auto transmission.

Sounds like a possible faulty sensor only reading upon start, so once the engine is hot then it reads it as such as kicks in the power. I wish I were more familiar with this car. My guess would probably be on temp sensor, probably on the engine block. Then again, I'm just shooting in the dark at blind leads. Anyone else with more experience have an idea?

Could be simple issue like the turbo vanes sticking open from carbon causing limp mode when the ECU doesn't see the desired boost response. In which case a simple vane cleaning is all you need. Unfortunately problems like yours are very difficult to diagnose without hands-on interaction.
Are there any check engine light codes stored?
