Hello, I have experienced that the engine in my Corolla Verso Diesel 2.2 177 hp, short distances in the long run does not last. It would result in defective soot filters. Renewals of the oil strippers would be necessary, up to the replacement engine. My vehicle is driven daily to work and back each 13 km. Otherwise short distances between 5 and 10 km.On weekends also times 30 km at a time.Once a year 2500 to 3000 km holiday trip within two weeks and various family trips. My question is that my engine is at risk in my driving cycle, should I rather think about switching to a petrol engine again. By the way, the above statements came from Toyota workshop circles. For your opinion in advance Thank you very much.
