2014-er Diesel…2.2 CRDI…DPF: What is short distance ? With me 2 x per day about 12 km and then again a few km (up to 10…15) per day, curvy distance mountain up and down…after about 7 km the temp. indicator is now in winter where it stops even during longer operation. If it is short distance, what can you do then (fuel additives / so I meant not to sell the diesel) ? Have read “What are short distances?”…but the second question is always/often “sold” b e-answers…
