How much did Passat 1.8t exchange materials for small water tanks in 2004?

Passat B5' s small water tank should actually be called warm air water tank. The original accessories are from Shanghai Bell Thermal System Co., Ltd., and the price is around 350 yuan (online shopping is acceptable). Replacement is more troublesome. Dismantling the center console, the labor cost is about 400 yuan for general auto repair shops, 500 for medium and large auto repair shops to 600 yuan, and 4S shops 1000 yuan. Because it involves disassembling the center console, it is recommended to choose a regular garage, otherwise many clips will be broken and many of your wiring harnesses will be in a mess, leaving hidden dangers for the circuit. It is recommended to dismantle it in warm weather and try not to dismantle it in winter, because it will damage many clips and center console. If the water tank does not leak, consider whether it can be cleaned with a high-pressure water gun. After all, the car is old and hurts when it is dismantled.
