hello.
for a few months now, due to home office, i have been driving my giulietta (2.0 JTDm 170PS @191'000km) 1-2 times a week, with mostly 50-80 km/h speed. lately, i have the feeling that, sometimes, it is jerking a little bit while accelerating. the clutch has been replaced a couple of years back about 25K kms ago, and it does not happen all the time, so, i am guessing, it is not the clutch slipping. and once in a while, i feel there is power loss.
it has been parked under a few trees, and i have not washed it for a long while. it is covered in pollen and such, so, i am suspecting, there might be some problem with air filter or the fuel itself. i finally got around to wash it, after 10-15 minute motorway drive. on the way back on the same highway back, the 'check engine' light came on, with power loss. i can drive it around sometimes now, but it mostly feels like in limp mode. i could not get over 40 km/h at 3rd gear on a hill, which was really sad, since a bit of light hill climbing is one of the most fun parts of driving it
i checked with a simple obd2 scanner, and read the error code P2002, which apparently means Diesel Particulate Filter Efficiency Below Threshold B1. so, maybe a sensor fault, or dpf regeneration failure. funnily enough, the 'check engine' light came on while on highway, during which it could do some regen.
since it does not have much power and i cannot dare to push the engine, i cannot drive it happily to get dpf regeneration going. i have already booked with the mechanic next week, but does it make sense to clear the error code, if 'torque lite' allows that, and check if i can drive around with some power for a dpf regen? or, is it safer to wait for the garage to get a juicy bill?
