had the pleasure of working on this guys with a DPF issue showing on the instrument cluster with a bars to high could this game still on there now funkos so up the car DPF light flashing a look at the temperature probes don’t find anything wrong has to go have a look to see how we can couple DPF out nothing we work so then we have to do is we had to put a 200 resistor on the exhaust temperature bank 1 sensor 3 press the DPF button and wait for it too just happen
the particulate matter accumulation radio ratio and all the way down to 14% and still watching the catalyst differential pressure is almost .02 kPa difference the particulate filter differential pressure 1.3 kPa and has not changed it looks like the trick with a temperature probe shorted with 200 ohm resisters really works
I’m waiting waiting by dick out matter accumulation ratio down to 4% and waiting for it to hit 0 and I’m hoping that the lot now down to 2% to 0% and I want the system to then self shutdown what I ended up having to do was stabbed my foot on the accelerator the minute I did that and the DPF mode came out the check engine light and DPF light stop flashing when out and the RPM can back to normal RPM speed therefore this thing is now solved
I then switched off ignition so the vehicle then stop stop the engine and then turn the ignition back on and I watched the exhaust temperature bank 1 sensor to drop from 700 all the way down to 81.2 that temperature is the same as the exhaust temperature bank 1 sensor 1 the exhaust temperature bank 1 sensor 3 is still at 742.5 degrees with ignition on as it has a 200 ohm resistor what im going to do is run the vehicle and see what happens because it looks like the whole lot is done by a mathematical equation and not differential pressure sensor being the only thing making the system be more blocked so to speak but then proceeded to River up the vehicle to 2000rpm watch the temperature exhaust sensor bank 1 sensor to go from 81.2 degrees all the way up to 450 and then I slowly let the RPM off and it’s slowly decreased all the way back down to 81.2 the particulate matter accumulation ratio is still at 0% so it looks like this is actually going to work leaving it in there I really like to see what happens with the vehicle in a couple of weeks time
never a walk in the park with a vehicle that has 245.000kms
Fuel Trims Are Adding Fuel As The System Is Running Lean
Conduct Road Test And Found That The Fuel Trims Are Causing The Check Engine Light To Come On
Front Radar sensor Calibration – Preparation phase
The Vehicle had came in from a panel shop with the front radar module replaced so typically the unit had to be recalibrated, (this also needs to be done if the grille has been removed and replaced, modified etc)

Normally when testing the performance on a Diesel engine with lack of power a boost leak would be found or a cracked intercooler, this vehicle has amassed 500,000kms and had never been cracked open servicing had been conducted by us since the word go, full synthetic 5/40 engine oil, upper cylinder cleans every service and no catch can present, here is some photos after 500,000kms
The vehicle now has full performance back to the engine and client now happy injectors and fuel supply is still in perfect condition after 500,000kms

To reset the timing belt indicator without Multi Information Screen (2013 on), proceed as follows:
Turn on the ignition.
Adjust the display so that it is showing the TRIP B reading. (See Diagrams)
Turn off the ignition.
Press and hold the trip meter button and turn on the ignition.
Continue to hold the trip meter button for 5 seconds or more ensuring that the timing belt warning light is flashing.
Release the trip meter button then within 5 seconds press it once.
You now have 5 seconds to select the interval to the next timing belt change. turn the trip meter button to advance through the interval options.
Note: the interval options will be a two digit number representing the kilometres multiplied by 10,000 eg: 15 = 150,000 Km’s
Or if not changing the interval hold the trip meter button for 5 seconds or more.
The display returns to the Odometer reading and the Timing Belt light will turn off
To reset the Timing Belt reminder message without the Multi Information Screen.
Switch the ignition ON and set the TRIP meter RESET knob (located on the lower right hand side of the cluster) to display the Odometer reading (not the trip meter reading) and then turn the ignition OFF.
Press and hold the TRIP meter RESET knob and turn the ignition ON.
Press and hold the TRIP meter RESET knob for a further 5 seconds, release it and then hold it in again within 5 seconds.
Enter into the SETTING MODE and change to T-BELT DISPLAY MODE.
Press and hold the TRIP meter RESET knob for a further 5 seconds.
The display now changes to TRIP B and the warning light turns off indicating reset procedure is complete.
Release the knob and turn ignition to OFF.
