Hello,
Thought of providing 3rd Service update on my Alcazar since it had a few aspects that might be useful for fellow owners. Kindly bear with me for the rather long post where I have tried to put the facts/ information as clearly as possible. Also, apologies for the low quality pics clicked hurriedly.
My Alcazar (Hyundai Alcazar 1.5D AT Prestige(O) 2021 Model) had completed 16k+ KMs and I already started getting Service reminders from Hyundai through SMS. (I had done 2nd Service after 1year at 8k KMs last year). I also had a long drive coming up in a week's time, hence decided to get the 3rd service completed before the long drive.
Called up Pavan Hyundai, Kanakapura Service Centre and took appointment the pervious day. Service experience was nice and got below the bill which mentioned 'DPF Logic update..' as well as 'AVNT Software Update'. Service advisor also mentioned "Software Update done sir" when I collected the vehicle after servicing. Needless to say I skipped the wheel alignment, balancing at the ASC this time as I had just got it done from Madhu's a couple of weeks before.
I drove the vehicle to office the next day of Servicing and felt that engine response got a bit better after the service - was also thinking if it is my perception or is it real. After about 10KM of drive (on NICE road) at the speed of ~80KM/hr, I started getting the DPF symbol along with attention indication on the instrument cluster. (I never got the DPF indication during the entire 2 years of ownership - partially due to my driving has been 80% on highways.) Parked the vehicle on the side and clicked a pic thinking to show it to the ASC just in case I have to. I continued my drive to office (total ~16KM) and parked at the office parking.
While returning home the 'Diesel filter regeneration required. See owner's manual' message started appearing. I tried holding the 'OK' button the steering wheel (as suggested on the instrument cluster) and got momentary message 'Regenerating conditions not met; start manual regeneration..' sort of message (could not click a pic as I was driving and the message was only momentary). Tried pressing OK a few times and by now it was clear that I would have to visit ASC to get it checked/ addressed before my scheduled long drive.
By the time I had reached office, SA called up to check about the vehicle condition after service and I had mentioned about the DPF indication. He quickly requested me to visit ASC to get it checked (as if he was expecting DPF related event would happen). I asked him if they hadn't cleared the DPF as part of the service. SA mentioned they usually do it if the indication is around 60 - 70% and in my case it was just ~40%.
I visited ASC the next day and the vehicle was directly taken to the service floor. I accompanied mentioning that I haven't removed any valuables from the vehicle (usually I remove all valuables before leaving the vehicle for servicing; this time SA mentioned it is just 1hr procedure and I could wait for the completion). I also wanted to see what was going on during the regeneration hence was prepared to wait. While entering the floor, another Alcazar (Diesel, manual model) was undergoing DPF regeneration and I was told that mine can start after completing the already progressing one.
Once the other one completed regeneration and cleared the bay, Equipment was connect on the OBD port of my vehicle and paired with the tab. It showed 42% 'Relative soot accumulation..' (a reading that was very close to what the SA had mentioned when I enquired initially). DPF regeneration was initiated manually and it took about 20 - 25 minutes to complete. The engine was at 2k RPM during DPF regeneration and was back to idling RPM once regeneration was completed.
Meanwhile the OTA Map update was going on in the background and that got completed as well. All went well and I returned back home in about 50 minutes.
I am contemplating two possibilities for the DPF indication to kick in:
1. DPF Logic Update kicked-in some sort of calibration and resulted in manual regeneration message
2. Engine was kept running/ idling for very long time on the service floor resulting in soot accumulation (less chances as the soot accumulation reading was still around 42% only)
I will drive the vehicle for a couple of hours in coming days to see if any further indications pop up after the logic update - I will update here if any. Just thought of being helpful and contribute to this otherwise full-of-rich-content forum by sharing my experience with the Service/ software update. Guess how I was able to converse with the SA/ Technician about DPF and the Regeneration related topic? Of course Tbhp and the DPF related threads here helped the conversation - and more importantly, handle the whole situation related to my vehicle with relatively cool mind. Being an informed soul really helps
Kudos to Tbhp and its fabulous Moderators/ Members/ Participants
