Is auto Diesel filter regeneration a periodical procedure or after sensing the filter quality? My car is a Kia Carens.

It isn’t periodical - your Kia Carens triggers DPF regeneration when the ECU senses the filter is filling with soot. It uses sensors and driving data to estimate soot load, then does passive regen on its own during steady highway runs, and active regen when needed by raising exhaust temperature to burn the soot.

If your use is mostly short, stop‑start city trips, the car can’t keep exhaust temps up, so active regens will happen more often, and sometimes you’ll see a DPF message asking you to keep driving. When that pops up, a 15‑20 minute run at about 60 km/h with gentle revs usually completes it. If you ignore or keep shutting the car mid‑cycle, the warning can escalate, and you may need the parked/manual regen from the cluster menu, or a workshop reset.

You’ll notice slightly higher fuel use, a hot smell, and a fast fan while regen runs. That’s normal. It is not tied to a fixed mileage or time; it’s entirely based on soot loading and your driving pattern.

Hi Team, After driving my new Tata Punch Turbo home from the showroom, I noticed a burnt smell and some white smoke coming from the bonnet. Since it’s a brand-new car, I’m a bit concerned. The showroom mentioned it could be due to driving in half clutch. Could you please confirm if this is normal or if it needs to be checked? Thank you

This isn’t normal on a brand-new Punch Turbo; book an immediate inspection and avoid driving it till they check it.Visible white smoke from the bonnet with a burnt smell right after the first drive points to oil or coolant touching a hot exhaust or turbo, or a loose clamp. A slipping clutch can create a burnt smell, but it rarely causes visible smoke on a day-one car unless something is already wrong, so the half-clutch explanation sounds like deflection. There is one harmless case, thin coatings or a bit of fluid spilled during prep can burn off and give a faint smell or light wisps for the first few kilometres, but that should fade quickly and not produce sustained smoke.Park it, look for any fresh wet spots under the car, and check the coolant level once the engine is fully cold. Note where the smoke seemed to start, especially front right near the turbo and exhaust, and record a short clip if it happens again. Take it back to the dealer, ask for a job card, and have them check for leaks, loose hose clamps, or clutch issues under warranty. Do not accept “driving style” as the only answer on day one.

I want to buy a car under Rs 12 lakh. It should be a petrol automatic and will be my first car. I need good ground clearance, a good engine and gearbox combination for 70% city and 30% highway use, and my daily running is around 30 km in Bengaluru traffic. Comfort, space, decent fuel efficiency, ease of driving, and long-term ownership are important to me. I do not want a Fronx, Baleno, i20, Exter, Punch, or Nexon. Please suggest a value-for-money option. Thank you.

Given your exclusions, the Skoda Kylaq automatic would be our first recommendation. Specifically, the Signature automatic is if you can stretch slightly. The 1.0 TSI turbo petrol and torque converter automatic are a very good combination for Bangalore traffic. The gearbox is smooth, the engine has enough punch for highway overtakes, and the car feels more premium and substantial than most options in this price range. Ground clearance is good, it is easy to drive, and it has the solid feel that many first-time buyers appreciate.Another strong option is the Mahindra XUV 3XO MX2 Pro automatic. It has a wider rear seat, feels bigger inside and is one of the most spacious compact SUVs in the segment. The torque converter automatic is smooth, and it is comfortable for city use. The downside is that fuel efficiency is not that great, and the boot is on the smaller side.If you are willing to consider a sedan, the Honda Amaze CVT is also worth a look. The CVT is exceptionally smooth in traffic, reliability is excellent, and it is the kind of car you can comfortably keep for a decade. The only reason it is not our primary recommendation is that you specifically mentioned wanting good ground clearance.
