Stop/start or DPF fault
Posted: Sun Sep 12, 2021 1:42 pm
I'm hoping someone can help.
I have a Qashqai 1.6 DCI and on the dashboard I'm seeing stop start fault and the engine light. Cruise control and speed limiter no longer work. There is also a dip in power around 2000 RPM. Other than that it drives ok.
These are the fault codes from my local garage.
P2002 - diesel particulate filter below efficiency threshold
P1525 - ASCD function
1130H/4400 - refer to OEM manual
P253F - engine oil deteriorated
Oil had been changed with no effect.
Regen failed and they believe a new DPF is required and will cost big money.
I need a second opinion and my own research suggest possibly a fault with the EGR or DPF pressure sensor.
Any help or insight would be great thanks
