Hello together, when I bought my CDI Smart Bj 2000 2 years ago I have to find out immediately that it will never get warmer than 60° C. Therefore I would like to know if it is the same with you. I know that the diesel (commonrail) should normally have about 80° C. Only in the summer I get it only with full drive (full gas) to 80°. Can it be that my thermostat is broken?
