There's a joke in audi's car circle: "odie has two things he can't hide — love for speed, and leakage of cooling fluid." from a4l, a6l to q5, q7, cooling system failures continued to dominate the maintenance list. But on the way to cova, chengdu, there's a 12-year-old rv specializing in odie, who knows these issues better than hands, and who dares to promise that it's hard to fix it without money。
The audi cooling system has five major diseases, closed-eye diagnosis
1. Pumps leaking anti-frozen fluids: three generations of e888 electronic pump seals are ageing or circuit boards are burned, and high-speed fans are often turned around。
Temperator card delay: failure to open leads to high temperature alerts, failure to close warm winds and higher fuel consumption。
Leakage in water tanks: “slow gas” along 80,000 km of plastic water chambers and aluminium cores, with a quiet reduction in anti-frozen fluids。
4. Warm wind valves are stuck: the driving position is hot, the co-pilot is cold or no warm wind, most of which is blocked by water。
5. Aging pipelines: plastic triples, rubber links are fragile at high temperatures, and re-freezing fluids are broken upon touch。
It's not a slogan. It's a rule
Many of the repair plants had run out of water, and there were thousands of major pipes. Hang on: can't change. For example, the pump sealing plant did not sell alone, and they found high-temperature and better fluorinated caps, at a cost of only a fraction. An old a6l owner was outraged: “there was another offer of 6,800 for a full pipe, and he found that only three were broken, and hundreds of dollars were done.”
How dare you say, "i can't fix it without money."
1. Original plant data: refrigeration system maintenance requires precise negative pressure values, dedicated computer activation of electronic pumps, fixed exhaust steps. They have complete original plant data and diagnostic equipment to prevent repeated air entry。
2. One repair: the water pumps will be replaced by simultaneous inspections of thermostats, water tanks, pipes, warm wind valves, which will be dismantled at a time to remove all hazards and will not allow the owner to return two weeks later to replace the thermostat。
3. Transparent offer: the owner agrees to replace the spare parts in the maintenance front, why, using the original plant or improvements, and the amount of time worked。
It's not pretty when you sell it
After each vehicle has been repaired, a visit is made on the third day and on the seventh day: it is confirmed that the water is normal and the anti-frozen fluids are high; and on the thirtieth day it is called back for free review. “no good repair, no money” is a promise written on the worksheet。
Your audi has these signals. Don't push
• water temperature alarm lights on
• the fan turns for a long time after parking
• not hot or hot cold
• frequent “disappearance” of anti-frozen fluids without trace on the ground
• smelt sweet inside the car (freezing fluid evaporation)
High-temperature pylons, starting with five-digit maintenance costs. The rong-hyun car audi specializing in 12 years only did one thing: fix every audi。
