Will Replacing Xenon Lights Affect the Annual Inspection?

Replacing xenon lights without adding lenses will affect the annual inspection. If xenon or LED bulbs are installed directly without lenses, bulbs with a color temperature exceeding 6000K will also fail the inspection. Permissible modifications according to the vehicle management office: According to the latest "Motor Vehicle Inspection Work Regulations" implemented on September 1st, installing roof racks, modifying the front grille, changing wheel rims, adding side steps, etc., are all considered legal modifications and do not require registration. Roof racks must not alter the vehicle's length or width, and their height should not exceed 300mm; front grille modifications must not change the vehicle's length or width; wheel rim modifications must maintain the original tire size; side steps must not extend more than 50mm beyond the body; bumper modifications must not alter the vehicle's length or width or create protruding parts. Illegal modifications include: Widening tires, modifying the intake and exhaust systems (structural changes); raising or lowering the chassis (structural changes); modifying headlights (structural changes); modifying the engine (performance changes); changing the vehicle's emblem—some people prefer to replace their vehicle's emblem with that of a well-known brand, which is illegal, may involve infringement, and will not pass the vehicle management office's inspection.

How many points are deducted for not using the turn signal in Subject 2?

Not using the turn signal or using it incorrectly will result in a deduction of 10 points each time. The specific regulations are as follows: Failing to use or incorrectly using the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a deduction of 10 points. Turning the steering wheel within less than 3 seconds after activating the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a deduction of 10 points. There are a total of 6 instances in Subject 2 where the turn signal must be used, which are: Activate the left turn signal when starting the vehicle; Activate the left turn signal when starting on the slope; Activate the right turn signal when the vehicle passes the side parking area and prepares to park 30 cm from the side line before reversing; Activate the left turn signal before shifting into reverse gear during side parking, as the steering wheel will be turned fully to the right during reversing, causing the front of the car to shift left; Activate the left turn signal before exiting the side parking area, shifting into forward gear, and turn it off promptly after exiting; Activate the left turn signal when entering the right-angle turn area and turn it off promptly after completing the turn. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For applicants of large buses, tractors, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For applicants of other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a garage, side parking, slope parking and starting (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves) as the five mandatory items (some regions also include a sixth item: highway card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include stake tests, slope parking and starting, side parking, single-plank bridge crossing, curve driving, right-angle turns, passing through width-limited gates, passing through continuous obstacles, driving on bumpy roads, narrow road U-turns, as well as simulated highways, continuous sharp mountain curves, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.

What does Volkswagen EPC mean?

Possible reasons for the EPC light to illuminate: The car's throttle is dirty and needs cleaning. Brake system malfunction, in which case the brake light also won't illuminate. Fuel quality issues may cause the EPC warning light to turn on. EPC (Electronic Power Control) stands for Engine Electronic Power Control System. When a sensor malfunctions or detects abnormal conditions, the control system will take corresponding measures according to pre-set programs. The following situations may cause the EPC light to illuminate: Engine intake system malfunction, throttle failure, fuel system failure, Engine malfunction, ECU control unit failure, brake light malfunction. Solutions for EPC light illumination: Troubleshoot intake system issues, use compliant fuel, clean throttle body, etc. Remove carbon deposits from relevant components through cleaning. Re-flash related data (this applies when other troubleshooting methods fail to resolve the issue). Other potential faults cannot be ruled out - actual vehicle diagnostics should determine the specific cause before proceeding with repairs. When the EPC light comes on, follow these steps: Restart the vehicle after turning it off and check if the EPC light remains illuminated. If not, there's likely no serious issue - the EPC light may occasionally activate due to external interference. If the EPC light frequently illuminates over a period, first check whether the brake lights are functioning (the brake lights may not work due to a faulty brake switch, bulb, or wiring - sometimes simply replacing the bulb solves this). If the EPC light persists after checking the brake lights, visit an authorized service center for inspection. Common EPC indicator colors are typically yellow or red. A yellow EPC warning light with normal vehicle operation means you should drive cautiously to a repair facility. A red EPC light indicates serious issues - pull over immediately and contact maintenance personnel, as continued driving may damage core components or compromise safety.
