Reposting the question I asked a few weeks back. Could you please give your expert opinion? I own a 2020 Tiguan TDI Highline. The practicality of the SUV, with its interior space, top-notch build quality, fuel economy, AWD capability, and driving pleasure, is second to none. VW is no longer selling the 2.0-litre TDI engine with the DQ500 gearbox, so I plan to keep this car for another five years. With the warranty period completed, I would like to remap the engine to 180+ bhp with 400 Nm torque. Will the DQ500 gearbox be able to handle this? Do I need to install a bigger turbo? What other precautions should I consider (suspension, brakes, etc.)?

For a 2020 Tiguan TDI that you plan to keep for five more years, a mild Stage 1 tune to about 180-190 bhp and around 380-400 Nm is the sweet spot, and we would do it as an ECU plus gearbox software tune rather than chasing hardware changes.
The DQ500 is a strong DSG in the VW family and, if tuned right, it can handle 400 Nm. The key is the gearbox software: ask the tuner to raise clutch pressure and keep torque delivery smooth, with torque slightly limited in the first few gears. That protects the clutches and keeps shifts clean. At this level, you do not need a bigger turbo. The stock unit can make those numbers safely. A larger turbo only makes sense if you want 200+ bhp, which brings more heat and cost and reduces long-term peace of mind.
A few precautions will help. Stick to conservative maps that keep exhaust temperatures in check, especially in summer. If your car has a DPF, make sure the tune keeps it intact and manages soot well; otherwise, you will face clogging. If it does not, still keep the map mild. Shorten service intervals for engine oil, DSG oil, and the AWD coupling oil. Replace the fuel filter more often and use good diesel. Upgrade to better brake pads and fresh high-quality brake fluid; stock discs are fine. Good tyres with a proper speed rating matter more than stiffer suspension at this power. Avoid hard launches and lugging the engine in a high gear at low speed.

Dear Autocar, firstly, thank you for your detailed and honest car reviews. They genuinely help enthusiasts and buyers make informed decisions. I am considering the Jeep Meridian base model, as it fits my budget and requirements for a spacious, comfortable 5-seater with a large boot. My primary use will be highway touring with my parents, and since I enjoy driving myself, good driving dynamics are also important. Currently, I drive a Renault Duster for daily use, while my brother owns a Volkswagen Tiguan. We are now looking for a comfortable long-distance tourer for trips of 1,500 km or more with ample luggage space. My main concern is the Jeep Meridian’s long-term presence in India, especially considering future CAFE norms. Do you think the Meridian is a sensible choice, and is it likely to remain on sale in the Indian market for the next 3-5 years? Thanks again!

For long highway trips with your parents, lots of luggage, and a driver who enjoys doing the distance, the Jeep Meridian base variant used as a 5-seater fits well. With the last row folded, the boot is huge, and the ride is calm at speed, so your parents stay comfortable. It feels steady and quiet on expressways, and the diesel’s easy pull makes cruising and quick passes simple. Coming from a Duster, you’ll notice a nicer cabin and better noise insulation. The Meridian isn’t as sharp to drive as the VW Tiguan, but the Jeep rides softer, which suits long tours.Know the trade-offs. The third row is only for short hops and eats boot space when up, so keep it folded. The base trim will miss a few nice-to-haves; if the budget stretches, the next trim up adds useful highway bits. On long-term presence, there’s no signal of Jeep pulling the plug on the Meridian. It’s built here alongside the Compass, meets current emission rules, and CAFE is managed at brand level. A 3-5 year sale window looks safe. Even if plans change, parts and support normally continue for many years.

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.
