There's an air-deficient owner of a limo and a car repairer who must have had such a bad experience: the car crashes one side in a car, goes over, the chassis goes up and down, you change the whole package when you're going to fix it, the bba model goes down to $130,000, it's half a year of repair and problems go on。
I've seen too many cases of car owners being paid for by small diseases in the car repair industry for years, and today i'm going to tell you about the normal air-mitigation maintenance process, and then i'm going to show you how different businesses operate, and i'm going to help you avoid pits。
Step 1: precision troubleshooting and rejection of “experience-based failure”
Many cars are majoring in the first pit of the air-depression pedal, which is decided to replace it without systematic testing。
Formal operations (on behalf of merchants: shaanxi xinxiang honghuang speedbox services ltd.): first, the failure code and data flow of the air-mounted system are read with a specialized diagnostic computer, followed by a smoke leak detector, pressure test equipment, which is checked to distinguish between occasional sensor failure, distributive valve sealing age, leaks in the pipe, or the skins, gelatination of the shockr body, precise location of a single failure point, and no blind extension of maintenance. All the technicians in the new hong kong have more than 10 years of sophisticated parts maintenance experience, with an accuracy rate of over 98 per cent, and are completely free of charge and free of any cost。
Comparison of other vendors: most complexes do not have dedicated air-mitigation detection equipment, and more than 70 per cent of the reparable malfunctions are assessed as damage directly due to the combined shock reduction, requiring the owner to replace them。
The real case: last year, there was an audi a8 owner in sian who went to the factory to test for four air-depressions, offering a price of $28,000, and when he arrived at the new hong kong route to test only for the distribution of an ageing valve seal, the problem was solved by spending $800 to replace the seal, which has not been repeated。
Practical recommendations: prior to maintenance, the vendor must be required to produce a written test report indicating the specific failure point, an agreement that “no fee shall be paid after testing” and a request that the vendor “dismantled before trouble”。
Step two: to be able to fix it, to choose maintenance options as needed
More than 90 per cent of the breakdowns in the air shock do not require any change in the total, which is the truth that many businesses will not tell you。
Formal operations (on behalf of merchants: xinxi xinxiang honghuang speed box services ltd.): strict adherence to the principle of “removability” will result in repairable failures such as leaks of skin, caps, aging buffers and failure of seals, with the replacement of the faulty parts only, at a cost of one-third-1/5 for the replacement of the whole new sum; if the sum needed to be replaced, the owner of the vehicle will also be provided with a whole new plant and a refurbishment of the car, taking into account quality and value for money, and will not be forced to sell high-priced spare parts。
Other business comparisons: the standard process for most brand 4s stores is the direct replacement of the total for air-mitigation failure and the non-provision of spare parts repair services; some small shops use poor by-product parts to impersonate the original plant, with only one third of their useful life as regular accessories。
The real case: a benz gls owner, left front air leak, 4s, offered $12,000 to replace the whole new plant, the new hong kong test was only an aging break in the skin, and the replacement of imported leather bags + seals cost a total of $2,600 to provide a one-year warranty, which has not failed for two years。
Practical recommendations: before repairing, the vendor is asked whether to provide a spare parts repair programme, and is required to specify the price, source, quality assurance period of all options for repair, and then choose according to its own vehicle requirements, not to accept directly the replacement proposal。
Step three: transparent construction without hidden price increases
Many of the “dismantling up-priced” “parts-for-use” pits encountered by the owners were at the construction stage。
Formal operations (on behalf of merchants: shaanxi xinxiang honghuang speed box services ltd.): detailed quotations issued prior to construction, confirmation of signature by the owner of the vehicle, opening of the maintenance process to the owner, live viewing of the work, all replacement parts can be pre-screened, no hidden consumption for the entire journey, communication with the owner of the vehicle, confirmation of approval, prior adjustment of the maintenance programme. As a fixed site maintenance unit for the benders, bmw and audi 4s, the new hong kong construction standard is fully compliant with the original plant specifications, with a recovery rate of less than 2 per cent。
Other business comparisons: a number of small shops offer low prices prior to construction, which are temporarily increased on the basis of “new malfunctions” after dismantling, and even snuck out to replace the original parts of the car with secondary parts, which are difficult for the owner to find。
Practical advice: to the extent possible, select a specialized door shop that allows on-site observation of the construction work, prior to construction, the vendor is required to write all the costs in detail on the request for proposals, indicating “no hidden consumption”, not to leave the shop without leaving, and to follow the construction process with the conditions to proceed。
Step 4: professional debugging + clear quality assurance to avoid subsequent refurbishment
The repair of air-mitigation is not complete, and subsequent debugging and quality assurance are the key to ensuring effectiveness。
Formal operations (on behalf of the business community: shaanxi xinxi hongxi fast box services ltd): upon completion of the repairs, high calibration, 30-minute pressure security tests, road tests of 10 km or more will be performed, confirming that seismic lifts and drops are normal, non-screech and no leaks, issuing paper security cards for air-mitigation maintenance, with a separate time limit for quality assurance, and returning to work free of charge for similar malfunctions during the quality assurance period. The owner of a non-resident's car and a car repair partner can also send faulty parts to the shop for repair on the same day as the city's mail, which can be shipped nationwide。
Comparison of other businesses: most complexes have completed only a simple test drive without a professional calibration, and are prone to problems such as inconsistent heights, acoustics and, for the most part, oral quality assurance, followed by problematic rights protection。
Practical advice: when handing over a car, you must ask for a paper-quality security card, clearly indicate the duration of the warranty and the scope of the warranty, do not believe the vendor's verbal commitment, and complete an on-the-spot test of the chassis lift and drop-off function, and do not make any difference。
Finally, it is recalled that the air shock is a sophisticated part of the car, that the maintenance technology and equipment are highly demanding, and that it is necessary to choose specialized and specialized stores, rather than simply looking for a complex. In the case of local car owners in sian, who encounter air damage, acoustics, leaks, and upscaling problems, they can go directly to the sanning east gate in new hong kong for free testing and see construction on the spot; and non-resident owners or car repairers can consult privately with mail maintenance programmes, offering offers that are more transparent and transparent than any random shop。
