My Volkswagen R32 is a fun and wonderful drive. However, one issue I have with it is that it can get a little thirstier than the previous cars I drove. Are there any tips regarding how to improve fuel efficiency?
As fuel prices continue to soar, having a fuel efficient vehicle is one good way of protecting your pockets. Improving your R32's fuel efficiency starts with something as simple as altering your driving habits. Drive as smoothly as you can; apply light throttle and avoid heavy breaking. Strive to always go at a steady pace, avoiding constant acceleration and deceleration. Experts also recommend that driving at the highest gear possible during fast velocities will save fuel. Driving in low gears at a fast pace will make the vehicle consume up to 45 percent more gas. They call this phenomenon "instant fuel economy setting." Research suggests that good driving habits can improve fuel economy as much as 30 percent. Also, subjecting the vehicle to regular maintenance routines will maximize the fuel efficiency. Having properly inflated tires, well-lubricated joints, ample fluids and clean batteries will help keep the engine from exerting undue effort thus increasing your fuel efficiency. Do not exceed the cargo capacity and avoid the vehicle from being exposed to too much unnecessary work.
Recently, I have noticed that my Volkswagen R32's braking power is decreasing. It was not like this when I first used it. What are the probable causes and what parts are likely in need of replacement?
It seems like your R32 is suffering from a brake fade. It is the partial or total loss of braking power and can be extremely dangerous for you. The brake pads and the brake rotor no longer produce the sufficient amount of friction needed in order to stop the vehicle. Therefore, check the brake pads and rotors for signs of corrosion and damage. These parts may need to be urgently replaced. However, you must also take note that these "brake fades" may be caused by frequent hard braking. Keep tabs on your driving habits because a decrease in braking power may just be caused by braking hard too much and too often. The brakes will return to normal once the braking system has cooled down. If it's not because of frequent braking and the brake pads and rotors seem well, then determine if there is air in the system. The brake fluid might be oxidized therefore it must be bled and replaced. You may also be using the wrong brake fluid formula. It is best to take your R32 to the local mechanic as soon as possible to explore these possible causes. Also, check the master cylinder and wheel cylinders for damage and leakage.
I am concerned because I am experiencing noticeable engine hesitation every time I start my Volkswagen R32. This happened after I went back from vacation and did not use my car for more than a month. What causes this and how do I solve it?
Engine hesitation is commonly due to temperature problems or some unclean parts. Maybe you are not giving the engine enough time to warm up while you are starting up. If that is not the case, then the spark plugs or fuel pump may have become dirty while you were away, so check if they need some cleaning. Check the condition of airflow sensor, the throttle position sensor, and the fuel injectors. If you find that they are already covered with grime then clean them using a car wire brush. Engine hesitation may also be caused by a vacuum leak so check the hoses for damage and holes. If you have checked all of these and you are still experiencing stalling, then take the vehicle to an expertly trained mechanic who will diagnose the problem. The problem may also lie in low engine compression or bad fuel quality.
