I have a 2013 cruze it 2.o diesel turbo. I get code 84 and 89 as soon I need power. Power cuts and lots of diesel smoke from exhaust. Any solutions PLEASE
Code 84 is reduced engine power. Frequent cause on the Cruze Diesel is failure to properly regenerate the Diesel Particulate Filter. (DPF).
Go to Jaycar or similar reputable electronics store and purchase an OBD2 WiFi Dongle (not Bluetooth, they give trouble) for about $70.00 AUD
Download Torque Pro from the Google Play Store ($4.99 AUD).
Plug the dongle in the diagnostics connector (below the coin holder tiny glove box thingy to the right of the steering wheel) Follow the instructions and connect your phones WiFi to the dongle via the Torque Pro app.
If it is a DPF issue you will probably have a couple or P (powertrain) codes,
P2463 Diesel Particulate Filter (DPF) Restriction - Not Regeneratable
P246C Diesel Particulate Filter (DPF) Soot Accumulation
Boost will be limited to about 12 pounds and revs limited to 3500.
We were able to fix these in my 2011 Diesel M6 by getting the vehicle to full operating temperature on a country highway run at up to 110 kmh in 4th gear for about half an hour so the exhaust was really hot. My brother in the passenger seat then kept reading and clearing the codes until they went away long enough for a DPF burn out to start. We had to keep driving and keep clearing the codes for about 40 mins at over 2,000 rpm until the codes did not come back.
After we were sure that the DPF had finished its active burn we continued to drive for another hour or so. We had a few Spanner lights come on when we did power runs from standing start up through the gears, causing the engine to de-rate again but putting the car in neutral and letting the revs drop to idle seemed to clear this.
After about 2.5 hours total high speed driving no more lights and all good.
Boost back to 28 pounds and revs back up over 4500.
