Generally, private auto repair shops do not replace car parts without the owner's knowledge. The main reason is that most private repair shops value their reputation to attract business. If they are caught replacing parts without permission, they could face severe consequences, including potential closure, which would outweigh any benefits. Therefore, private repair shops usually avoid taking such risks. Do not casually agree to the removal of critical components: Complex major components like engines and transmissions have strict assembly parameters. Some brand-specific parts even require assembly in absolutely dust-free and cold environments. Therefore, car owners should not readily agree to the disassembly of these critical parts. Ensure the reliability of replacement parts: When repairing a car, always choose parts with quality guarantees. Many repair shops, including some authorized dealerships (4S shops), may clean and reuse salvaged parts, passing them off as new or even using substandard components, which can pose hidden risks to the vehicle.

I've been into cars for over a decade and often tinker with repairs myself. Private car repairs can indeed involve parts being swapped out, especially at small shops looking to cut costs by using used or refurbished parts instead of new ones. I've encountered this several times myself – for instance, being quoted a new brand of brake pads only to find out they were replaced with off-brand ones. The reasons vary: shop staff might be understaffed or unscrupulous, trying to make extra money off you; or they might not return the old parts, leaving you with no way to verify. My advice is to stick with reputable, familiar shops and insist on getting the old parts back for comparison. Before repairs, request a detailed quote including part models and prices. Most small repair shops are trustworthy, but it's always wise to stay cautious. This issue concerns driving safety – if critical parts are swapped and something goes wrong, the consequences could be severe. That's why I always take a test drive after repairs to check everything.

As a long-time car owner who frequently drives to commute and pick up the kids, I'm quite cautious about car repairs. The issue of having parts swapped out at private repair shops isn't unfounded—I heard my neighbor Lao Wang fell victim to it, with his engine oil filter secretly replaced with a substandard one, leading to subsequent malfunctions. This mainly happens because some shop owners cut corners or lack oversight. Don't just go for the cheapest quote; understand the repair process, like checking replacement records or monitoring the workbench. Safety first, especially with family members involved. Before any repair, I always check the shop's license and online ratings. Keep the warranty slip after repairs and file complaints if issues arise. On a related note: regular maintenance can reduce the need for major repairs, avoiding such risks. In short, stay vigilant—don't just focus on saving a few bucks.

Does the all-new Bora have anti-collision beams?

The all-new Bora is equipped with anti-collision beams, which are concealed inside the bumper and within the doors, effectively protecting passengers in the event of significant impact. The working principle of the anti-collision steel beams is that during medium to high-speed driving, in case of a collision, the front anti-collision beam distributes the impact energy to the energy-absorbing boxes. These boxes then immediately deform, dispersing the remaining energy to the longitudinal beams on both sides, allowing the entire body structure to absorb the energy. The dimensions of the all-new Bora are 4562mm in length, 1793mm in width, and 1468mm in height, with a wheelbase of 2614mm. While the size has increased, the interior layout has become more rationalized. Compared to the previous generation, the actual interior seating space of the all-new Bora has significantly improved, with front and rear legroom increased by up to 20mm.

Why is water dripping from the exhaust pipe of the Fabia?

Water dripping from the exhaust pipe of the Fabia is because gasoline generates water vapor and carbon dioxide after complete combustion. Water vapor is colorless and transparent at high temperatures, but when the temperature drops below 100 degrees, the water vapor condenses into water. If the condensed water droplets are very small and suspended in the air, the water vapor appears as white gas. When the ambient temperature is low, the condensed water vapor accumulates and turns into water droplets, which are then discharged through the exhaust pipe. The Fabia is a compact family car under the Skoda brand, equipped with either a 1.4L or 1.6L engine from the EA211 series, paired with a 5-speed manual or 6-speed automatic transmission.
