Hello diesel driver Often written, often read — cold problems, despite winter diesel the car does not start or dies miserable after 1 to 2 minutes of operation.This problem I had with my L200 KAOT Bj07 in the previous winter and this winter in the last days very often.Everything emptied, tank empty, pipes empty filter removed, disassembled picobello cleaned(there was nowhere water in) Everything filled with new winter diesel, ventilated, After short run the engine sounds like a bag of nuts rolling down a mountain and off. Now I have found a filter heater set from biopoel at e..y, so costs 70-80 Euro. Now my question about this. Has one of you ever installed this filter preheater before? Is there any experience? And up to which temperature max. diesel can be preheated in order not to damage the sensitive injection system.
