Hello, maybe someone has a tip for me. Starting base is a series Smart Cabrio 0.7 61PS Built 2003 engine before 40tkm completely revised, 1. Excess piston etc. Car ran until now unobtrusive and error-free. I played with my software Optimizer together a performance increase on the ECU. In the end we tried 2. The big file with 82PS and now a slightly weaker one. Both come from DIM Sport as I have seen it. But with the files my Smart does not run clean. Under full speed he starts to jerk from 3000U/min and exactly all 5min he sets both charging pressure errors P2052 & P2011 and goes into the 0 bar emergency run. Even if the engine runs only in idle run the error is set after 5min. -All underpressure hoses are new -Turbo new -Zündkabel i.O. -Zündkerzen neu -neue Gasopressregrebel Benzindruck versucht i.O. Charging pressure display installed. It also builds up up to 1.1bar Charging pressure can’s. I can’t do not give you a limit to the back with my battery. My battery.
