Engine Management Coolant Temperature sensors make up 34 percent of the top ten selling Cambiare parts for the polo. Technicians should be aware that a failure of this component will result in higher than normal fuel consumption, poor hard start and reduced power.
- Pencil coils come in second in the top ten sellers at 28 percent. A failing coil swill produces a misfire, hard hot or cold start and reduced performance. It is recommended that all of the coils are replaced at the same time as a single failed unit to maintain system balance and reduce the possibility of an impending failure of another coil, as they are likely to have all been in service for the same period of time.
Oil pressure switches come in third at 21 percent of Cambiare sales for this model, being replaced for a mix of leaking oil and failing to operate the oil pressure warning light correctly. Failure of the oil pressure warning system can lead to the driver being unaware of a low oil pressure situation can result in an expensive engine repair.
