The issues were not resolved and I couldn’t take the vehicle back to the service centre, as the service centre is more than 100 km away
BHPian vamship recently shared this with other enthusiasts.
Below is the sequence of events:
March end 2023 (9500 KMs on OD): Due to a rat bite issue, the service centre removed and refitted the vehicle’s wiring, as they said there was an exposed wire somewhere which was causing the ABS sensor issues. They kept the vehicle for almost two weeks to identify and fix the ABS issues.
There were no issues other than an ABS sensor before wiring R&R.
After this wiring R&R, I started seeing two main issues:
Vehicle randomly powers off when the clutch is depressed/used.
- It’s very random and there is no pattern.
- If the vehicle is at very slow speed(5-15KMs), the engine totally powers off, and I will have to manually start the engine(I have now learnt to look out for this issue at low speeds, and let off the clutch slowly and the vehicle starts with a Jerk)
- If the speed is at a bit higher speeds(25-100), and I let go of the clutch very slowly, the vehicle keeps moving and starts itself with a slight jerk.
- The issue can be very picky, sometimes it will never show up for 100s of KMs, but sometimes bother me continuously for a full day.
- Here is the video of the same issue, u can identify when the engine powers off as all the cluster lights come on for a sec.
I get DPF issues every 200 to 300 KMs(after successfully parking regeneration). I even got it once within 50KMs for parking regeneration.
Image1 (did parking regeneration at 15400 km):
Image2 (received DPF error again at 15700 km, actually at 15640 as I could take pic only after reaching home):
April 2023 (10500 KMs): I take the vehicle to the same service centre that did wiring R&R, and they were more interested in doing the 3rd service than fixing the problem. As I couldn’t replicate the vehicle powering-off issue when the clutch depressed, they just checked multiple things and said everything is OK.
The issues were not resolved and I couldn’t take the vehicle back to the service centre, as the service centre is more than 100 km away and we had multiple marriages in immediate family and relatives. The vehicle accumulated a lot of KMs during this Month
May 2023 (14500 KMs): I take the vehicle to the same service centre that did the wiring R&R, they say they found a neutral sensor wire being loose, which they fixed and said they also checked everything about DPF which has no problems. Kept the vehicle for almost 1 week.
- Checked fuel pump and fuel filter, and no issues found by the service centre
- Checked Fuel quality from the fuel tank and diesel filter, with no issues.
- Removed all DPF sensors, found no issues so fixed them back
- I left the vehicle at the service centre, they identified a neutral sensor wire being loose and fixed it.
- Took the vehicle back after 20 km of test drive, and asked them to check all the DPF values. During this, I noticed the “Total regeneration demand counter” being 255 and I asked about it. They said it could be the number of times the vehicle did “Auto regeneration”
June 2023: I still am facing both the above issues, and as I am now back in Bangalore, took the vehicle to the nearest service centre. I asked the service centre to check the DPF values again and I see the “Total Regeneration demand counter” at 255. The guys here say this value is not related to “Auto DPF Regeneration” and it’s related to soot particles.
Does this mean the Auto regen is not happening in my vehicle?
I have now left the vehicle at Bangalore service center, and hope the issues are resolved.
