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.

The reason the Maruti Eeco 6-seater Standard variant is not offered with factory-fitted AC is largely a cost and positioning decision by Maruti. It is worth noting that this restriction is specific to the 6-seater Standard variant. The 5-seater versions of the Eeco are available with factory-fitted AC, so Maruti is not avoiding AC altogether on the model.As for adding AC later, yes, it is technically possible to fit an aftermarket AC, and many owners have done so. However, we would generally not recommend it. Factory-fitted AC systems are integrated with the engine calibration, wiring, dashboard layout and cooling system. An aftermarket setup may not cool as effectively, can affect reliability and could create issues with electrical components over the long term if not installed properly.If AC is important to you, the better solution is to buy an Eeco variant that comes with factory fitted AC from the outset or go for alternatives like the Renault Triber or the Nissan Gravite.

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.
