The MAF sensor is the instrument that checks the temperature and the weight of the air that is entering the VW Polo engine. This information is then sent to the on-board computer, which calculates the correct amount of fuel that the engine requires to operate at.
The sensor works by measuring the current that is required to check the temperature while the air blows past. The MAF will start to clog up with dirt and other particles over time and this blockage is the thing that can cause your engine to have problems. The symptoms are exactly what was related to this problem. Poor starting, the engine would not run properly and would not accelerate, especially up hills.
Clean MAF sensor
Some people say that if you can clean the MAF sensor at regular periods then these problems would not arise, but we have always found that we have had to replace the part. Importantly, we also fitted a new air filter and the VW Polo was a different car. It was road tested and the change of the MAF sensor revitalised the car, back to normal engine functions.
We also noticed that the steering had got a knocking noise and a vibration and on inspection found that the car also needed a Front Arm rear bush. We fitted this new bush and adjusted the wheel alignment. Here at Pellonautocentre we can repair all makes and types of cars.
It was an expensive day for the customer, but you would be surprised how many of our customers drive their car until it drops to pieces, nothing new there?
