What Causes BMW to Shake and Stall During Cold Start?

For BMW 5 Series shaking and stalling during cold starts, the most common cause is carbon buildup. Carbon deposits typically accumulate on the inner walls of the throttle body, the intake valve heads, the inner walls of the intake manifold, the piston tops, and the inner walls of the combustion chamber. It is recommended that owners visit a repair shop to identify the specific cause and resolve it promptly to avoid affecting vehicle performance. Below is a brief introduction to automotive carbon deposits: (1) Excessive carbon buildup on the inner walls of the throttle body can restrict airflow, leading to difficulty starting or stalling at idle. Once the engine reaches normal operating temperature, the throttle opening may exceed the normal idle value, causing the ECU to repeatedly adjust the throttle valve position, resulting in erratic idle speeds. (2) Carbon deposits have a porous, sponge-like surface. After the car has been parked overnight or for an extended period, during a cold start, most of the fuel injected by the injectors is initially absorbed by the carbon deposits, leaving insufficient fuel in the combustion chamber for proper ignition. Only after multiple injections during cranking does enough fuel enter the combustion chamber for ignition. This condition inevitably makes starting difficult. More severely, if carbon deposits accumulate excessively on the intake valve heads, causing the valves to seal improperly, cold starts become even more challenging.

How to Remove the Rear Seat of the New Santana?

To disassemble the rear seats of the Volkswagen New Santana, first remove the right-side fixing buckle, then the left-side fixing buckle, and separate the rear seat safety belt buckle to detach the seat. Below is relevant information: 1. The all-new Santana is equipped with an advanced automatic transmission featuring a six-speed multi-gear design, which optimizes power output at different engine speeds, reduces engine speed fluctuations, minimizes noise, and lowers fuel consumption. Its included Sport mode (S gear) with a sport-tuned shift curve significantly delays upshifts, delivering stronger power output for a more exhilarating driving experience. When descending into underground garages or steep mountain roads, the S gear effectively limits gear increases, utilizing engine braking for comfortable and safe handling. 2. Extensive configuration options: The all-new Santana offers a wider range of configuration choices across different trim levels. The 1.6L manual transmission model now includes a luxury version option, featuring electric power steering, leather seats, heated mirrors, a trip computer display, automatic air conditioning, and six airbags. Cruise control and front seat heating are optional. The luxury version also comes with an Electronic Stability Control system (though the New Santana’s version lacks a switch function) and a Hill Assist system, while the 1.4L and 1.6L Comfort versions offer these as optional upgrades. Additionally, all models except the three Trendline versions are equipped with a power sunroof.

How to Distinguish Between Ghibli and Quattroporte?

Ghibli can be considered as the short-wheelbase version of the Quattroporte, with the most noticeable difference being that the Ghibli has a smaller body than the Quattroporte. Below are the key differences between these two models: 1. In terms of engine configuration, the Ghibli only comes with a V6 engine in two power versions, while the Quattroporte offers both V6 and V8 engines. Additionally, the Ghibli has an all-wheel-drive (AWD) version, whereas the China-spec Quattroporte does not. However, the U.S.-spec Quattroporte does offer an AWD version, but it is limited to the V6 engine—the V8 does not come with AWD. Essentially, the Ghibli can be seen as the short-wheelbase variant of the Quattroporte, with a smaller body. 2. The Maserati Ghibli was designed by the renowned Italian designer Lorenzo Ramaciotti. The new model incorporates elements from the sixth-generation Quattroporte and GranTurismo but presents a sharper, more stylish, and dynamic overall appearance. The Ghibli's cabin features dual-tone leather to emphasize sportiness and luxury. The materials and craftsmanship, sourced from the high-end Italian furniture brand Poltrona Frau, ensure top-tier quality. Additionally, a premium audio system by Bowers & Wilkins is available as an optional upgrade. 3. The Ghibli shares its subframe and electronically controlled suspension system with the sixth-generation Quattroporte, but its tuning is more focused on handling. The sixth-generation Quattroporte extended its body to 5,052 mm primarily to enhance rear passenger legroom. Despite the Ghibli's shorter body, its rear legroom is comparable to that of the fifth-generation Quattroporte, which is quite generous for a performance-oriented executive luxury sedan.

What are the differences between BMW 320li and 325li?

BMW 320li and 325li differ mainly in their engines, but there are also significant gaps in wheel rims, interior, and safety configurations. The main differences are as follows: 1. Engine: The 320li has a 4-cylinder engine, while the 325li has a 6-cylinder engine. The 320li's engine is an improved version of the previous generation E46 318i engine, whereas the 325li features the new magnesium-aluminum alloy engine from the E90 series. 2. Brake discs: The 320li has front 292 and rear 296 brake discs, while the 325li has front 300 and rear 300 brake discs. 3. Wheel rims and tires: The 320li comes with 16-inch rims and 205 tires, while the 325li has 17-inch rims and 225 tires. Although both use run-flat tires, the Continental run-flat tires on the 320li are of a lower grade compared to those on the 325li, with differences not just in width. 4. Interior: The 320li has a standard steering wheel, while the 325li features a sport steering wheel. Except for the top trim of the 320li, the audio system is downgraded, including the amplifier, whereas the 325li is equipped with HARMAN/BECKER mid-range audio system across all trims. 5. Safety: The 320li has a cruise control system, while the 325li features a dynamic cruise control system. The 320li's DSC dynamic stability system is the same as the older 318i's, whereas the 325li comes with the truly new-generation DSC advanced dynamic stability system.
