Hello, I have a question for the experts here. I have a Vivaro 2.0 Cdti EZ 01/2009 (must be Bj. 2008). The following problem. It started that my heater did not work anymore, the temperature indicator showed nothing and sometimes it was sniffing up to almost maximum. On a ride then the water is boiled out. At the examination a cooler tube was blown by the coolants. This replaces and tries to vent the system (almost not possible). Now the next GROSS problem comes up, as soon as the Vivaro is warm the engine warning lamp comes out and it goes out. No longer to start, analysis system writes no connection to the engine control unit. The next day it is started again, at the venting attempt it has already gone out again and the same game as before. Only after cooling it runs again for about 10 minutes. Error message p2149 and p2146. Währ supercool if one of you could tell me what is going on here. Is it the control device? this can be repaired as cold? Or it is not possible for me to imagine the greetings of Marcus.
