Do you notice that your car is going bad? Cars look a bit like a body. There are detectable symptoms that indicate where the disease may be and no matter what car you have Audi, Porsche, BMW, etc., your senses can help you detect them.
Touch. Car behavior
If any part is wrong, you will notice that the car is not “as usual”. Sometimes these changes do not happen all at once, so it’s hard to notice. Vibrations, harsher direction indicates that it’s time to do a review.
Vibrations: they are caused by unbalanced wheels, although any problem with the tires can cause them. It is better to treat the problem as soon as possible as it can end up seriously damaging the suspension and the steering system.
Rolling and lack of precision in curve: It is possible that your shock absorbers are in poor condition. Lean on the body, on each wheel and pull down. If the bounce back bounces more than once, change the suspensions.
The car goes aside: maybe the direction is damaged or misaligned.
Hearing. Strange sounds
If your vehicle is not in good condition, it probably ends up sounding differently. And is that if some part of the car does not work properly, the first signal that is received, is a strange noise and out of place. Sharp sound: it can be a damaged or slack strap. Which is in particular? See if it sounds when the air conditioner is activated, when the steering is turned, or when the radiator fan starts.
Small noises: just imperceptible, but you notice that the car does not sound like when it was new. It can be from a stuck (a piece that moves the movement of the cams to the valves) to a shovel of the damaged fan. Even that the oil level is low, or a loose hubcap.
Unstable Hammering: usually means there is a problem with the suspension or a bearing.
Creak: very often comes from the brakes, more specifically from the disc brake assembly and that is why you hear it when braking. It will be solved by cleaning the brakes and recharging the brake fluid. If you have done this already, remove the wheel and check if the rotors or the brake pads are worn or deformed. The “squeals” come from the slots in the rotor faces of the disc brakes.
Sight. Stains left by your car
Do you see spots appear under your car? A small, punctual spot may not mean anything, but it always indicates a leak in some system. But if they appear constantly, check if:
Blackish stains: possibly a joint in poor condition and the stain will be quite large.
Spot light blue, green / yellow or orange: that’s antifreeze. Your car’s engine may have been overheated or there may be a leak (in the radiator or water pump).
Reddish oily liquid stain: The leak belongs to the power steering system or transmission.
Smell. Rare odors in the car
Smell of sulfur: What does sulfur smell like? Like a rotten eggs. If your car smells like this, you have a problem with some emission control system, like the catalyst.
Smell of burnt: beware! It may have to do with the electrical system. Take it to the workshop as soon as possible.
Acrid odor (like burned oil): it could be an oil leak, look for spots when you park it and try to locate it.
Please, do not try to prove anything about your car, especially liquids!
