My 2023 Altroz diesel with stage 1 tune: 5700 km ownership update

The car was tuned to stage 1 (115 hp, 280 nm) and for the most part, the DPF warning frequency has reduced.

BHPian Chaman K recently shared this with other enthusiasts.

My father bought an XZ+ Dark diesel in January of this year (MY 2023) because of the excellent dynamics and practicality. The car has done 5700 kms as of now, it is stage 1 tuned now and drives much much better.

The auto AC goes nuts even at 26° C and we had thought the random clunk was due to stone hitting the underbody!! Will get it rectified.

Other niggles faced:

1) I want to know if there's some sort of fuelling roughness when giving full throttle as it's present in our car (since new) brought it up at TASS who said it's normal for the diesel (I believe this may be the cause for DPF issues)

2) DPF issues - My father's daily running is pretty low (about 3 km daily) and the car doesn't even warm up completely during the daily stint. The DPF light is so small on the cluster so it was missed the first time around which led to the car going into limp mode as well (before the tune). I drove the car that day and en route to the dealership after 20 km the limp mode and DPF light went away though the check engine light remained which had to be cleared. Later on, the car threw the DPF light about a month later (when running was low without the weekend drive to our native place) for which my father did some driving around the highways and it promptly went away.

The car was tuned to stage 1 (115 hp, 280 nm), and for the most part, the DPF light didn't come (the frequency reduced) however when it came it went away. But recently the DPF light came and didn't go away, after some driving it did go away but the following day power was reduced and the check engine light was on along with a gushing sound from whenever the turbo was supposed to spool up.

In the service centre when it was brought, we got to know that it was due to the intercooler pipe which had come loose and it was fixed and the car was handed back to us who asked us to come later to clear the check engine light cause they didn't have the laptop for the time being. After coming back they took the car in for about 2 hours and performed a thorough dpf regeneration.

They informed me that DPF regeneration has to be done manually after 3-4 times on the cluster even if it goes away, with the cleaning of the oxygen sensor, 30 minutes of park regeneration and 30km of driving (which is supposedly their procedure). We were not charged for any of the DPF issues.

Drove the car to Bangalore and back to Mangalore (around 1000 km since then), and I noticed that there was brake fade during hard braking at times.

3) Slam the trunk - Or else it doesn't close completely

4) FM Radio - The overall sound system is excellent in the car but the reception of FM radio is sub-par and there's a peculiar issue of sudden volume increase in between which makes it unusable.

5) Screen flickering - This happens when the car is parked out in the sun and the interior is hot. The flickering goes away when the cabin starts to become cool (with AC)

6) Blind spot - more of a design flaw I guess as the A-pillar is pretty huge. Does need some time to get used to.

Overall, it's a great car and we have no regrets about the purchase. Would love to hear the inputs from fellow owners and BHPians
