Check Engine Light Diagnosis At Duffy’s Repair Service

Your browser does not support video

Hello Ashland auto owners. Have you ever had your check engine light come on? Did you panic? Or just scowl and ignore it? What should you do? Pull to the side of the road and call a tow truck? Or just keep driving? What does that little light really mean for Ashland car owners?

First of all, the Check Engine or Service Engine light does indicate that something is wrong. That’s why it is called a warning light. But the something that is wrong might be a loose gas cap, or it might be serious SUV engine trouble. That’s why Richmond motorists often don’t know how to respond to it.

The check engine light has two modes: it flashes or it stays on. A flashing light is serious. You need to get your vehicle to Duffy’s Repair Service in Ashland ASAP. No, you don’t need to call a tow truck, but, yes, you can’t wait to get your car serviced. If your check engine light is on and flashing, you should not tow trailers, haul heavy loads or drive at Virginia interstate speeds. Any of these could lead to serious damage that could result expensive repair bills for Ashland motorists who ignore it.

A steady check engine light is less serious, but that doesn’t mean it can be ignored by Henrico motorists. You should plan to get your vehicle inspected at your local Ashland automotive service center the first realistic opportunity. Not the first convenient opportunity, but the first realistic one.

Before you take your SUV in, however, check the gas cap. A loose gas cap can trigger the check engine light. If it is loose, twist it until it clicks three times. If that was the problem, your Ashland engine light will reset after several days. However, if it stays on, then you need to schedule an inspection at your Ashland auto repair center center or Duffy’s Repair Service.

Modern automobiles have a computer in the engine that monitors and controls many of the engine functions. When the computer senses something wrong, it first tries to fix the problem itself by adjusting the SUV engine. If the problem persists, the computer signals the check engine light to come on.

This process stores a trouble code inside the SUV engine’s computer. Your service advisor scans the computer and reads the code. This does not tell the service professional exactly what is wrong with the car, but it gives him a good idea as to where to start looking.

It is NOT good auto advice to deal with a check engine light by disconnecting the battery. Yes, this makes the light go off, but it doesn’t solve the problem. It’s rather like trying to put out a fire by disconnecting the smoke detector. Also, disconnecting the battery will erase your SUV’s computer memory. An engine’s computer, over time, learns to adjust for peculiarities of the specific SUV engine, for driving conditions in your Ashland area, and for your driving habits. Losing its memory means it has to learn and adjust for these things all over again.

Also, don’t buy a cheap consumer scanner or get a trouble code read at your nearest Ashland auto parts store, then try to fix a problem yourself — unless, of course, you are a trained Richmond mechanic. Today’s auto repair equipment is fairly high-tech and knowing a code is only an indication of where a problem might be, not the answer to what is wrong. Trying to save a little money by doing it yourself may end up costing you big in the long run.

Of course, the best thing to do is to keep that pesky check engine light from coming on in the first place. Good car care and routine preventive maintenance go a long way to keeping your SUV out of your Ashland auto repair shop. But, if that light does come on, be smart. Take care of the problem early, and take care of it professionally.

Differential Service in Ashland, Virginia – What You Need To Know

Scratching your head? Don’t worry, if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Ashland, Virginia, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Ashland drivers might even have two or three.

Not surprisingly, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Ashland, Virginia home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Ashland auto owners’ tires would scrub and hop along the pavement during turns like the early cars.

Ever noticed the big bulge in the middle of the rear axle on trucks? That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complex to some Richmond motorists – but you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but- we’ve said it before – they need to be properly lubricated in order to stay strong. So from time to time, you need to schedule a differential service in Ashland at Duffy’s Repair Service. The used fluid is drained and replaced with clean fluid. Some vehicle manufacturers advise certain differentials to have special additives installed.

Get your differential serviced at Duffy’s Repair Service in Ashland.

Recommendations for the time and mileage interval for servicing your differential can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Ashland, Virginia Duffy’s Repair Service service advisor or your manufacturers owner’s manual for recommendations.

How and where you drive in Ashland will have an essential impact as well. If you drive on dirt roads or through streams around Richmond, Virginia, you’ll need to service your differential much sooner than if you always stay on Virginia highways.

Tire Replacement: What Ashland Drivers Need to Know

Looking at getting some new tires? The choices at Ashland tire stores can be a little overwhelming. Suppose you have an SUV and are trying to decide between all season tires or some that are also rated for off-highway. Do you get off the payment on the outskirts of Ashland more than most? If so, some additional off-road traction would be nice.

Tire Replacement: What Ashland Drivers Need to KnowMaybe the real reason for wanting those off-highway tires is that they look cool. Well there’s nothing wrong with that. If you make sure that you’ve got your functional needs covered with your selection, then you can have some fun with where you go from there.

Let’s suppose you zip around Ashland in a sporty car. You may like to run a high-performance summer tire when the weather’s good. When Virginia weather turns cold, you can put on high-performance winter tires. For the kind of driving you like to do, you want full-on performance tires. All-season tires are naturally a compromise that works well for most Ashland drivers, but since you have a choice, go for dedicated summer and winter tires.

When it’s time for new tires, visit with a knowledgeable Duffy’s Repair Service tire professional. Describe your needs and wants. He’ll come up with some selections for you to discuss. And once you settle on a type of tire, there are options for special needs: like pulling a trailer or carrying heavy loads.

Tires are one of the biggest purchases for Ashland drivers. With so many choices, you’ll be able to get what’s best for you. Take their time. And don’t worry about what’s in stock. If you want something that isn’t here at Duffy’s Repair Service, manager Billy Duffy can order it. Chances are you’ll be rolling on your new tires in a couple of days.

What Is A Differential And Do You Have One?

With front-wheel drive being so common these days in Ashland, Virginia, the differential is just taken care of during a transmission service, so most Ashland drivers don’t even have to think about it. And rear-wheel drive differentials don’t need to be serviced for years, so it’s understandable that it’s not something on the top of mind for our Ashland customers. So it’s not uncommon for car owners to not know they have a differential let alone know that it needs service.

Call Duffy’s Repair Service in Ashland at 804.798.5922 for information about differential service, or stop by our Ashland, Virginia auto center at 9974 Lickinghole Road 23005.

To better understand what a differential does, think about our local Ashland high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That’s to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It’s a very important function for us Ashland car owners. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars in the Ashland, Virginia area weigh between three and six thousand pounds – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That’s a lot of work and requires very heavy duty parts. And those essential parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool.

The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that breakdown over time. So car makers recommend intervals for replacing your differential fluid.

Your friendly Duffy’s Repair Service service professional will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. Then he’ll replace the fluid and install the additives if necessary.

Your Duffy’s Repair Service service advisor can look up the car maker’s recommended service interval or you can check your owner’s manual. Give us a call at 804.798.5922 for more information about your differential service.

What is That? Check Engine Light Service At Duffy’s Repair Service

Your browser does not support video

Okay. You went to your local Ashland car wash and while your SUV was under the dryer, the check engine light started flashing. Panic! What did you just do? Something is seriously wrong with the SUV! You head for the nearest Ashland service station, but on the way, the check engine light stops flashing, and just glows red. Hmm. Maybe things aren’t as bad as they seem. You decide to wait until payday to take your SUV in to get serviced. In the meantime, the check engine light goes off. What? You decide the light must be faulty, or that when it comes on it doesn’t mean anything, or that it’s just in your SUV as some sort of scam to get you to pay for unnecessary expensive repairs. You’re glad you didn’t take your car to the Ashland repair shop and resolve to ignore that engine light in the future.

Whoa! Let’s look at what really happened. Your SUV was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered: there shouldn’t be that much airflow when the SUV engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The check engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the check engine light to stop flashing. The SUV doesn’t need immediate attention; but there was a problem, and it should be checked out by your technician. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a check engine light, but you should remember that a computer can’t think for itself, it can only follow its programming. It doesn’t know the difference between a car wash air dryer and a serious malfunction in your SUV engine. That doesn’t make it useless. It just means you have to be the smart one.

Being smart doesn’t mean ignoring your SUV check engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your SUV engine. It knows what parameters are normal, and when a reading may indicate a problem. It uses the check engine light to let you know when something isn’t right. It then stores a code in its memory that a tech can retrieve that indicates which reading was abnormal.

The service professional uses this code as a starting place to find out what’s wrong with your SUV. It’s like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what’s causing it. It’s probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what’s NOT wrong with you. Fevers don’t accompany stress headaches, ulcers or arthritis, so there’s no sense in testing for those conditions.

Your Ashland service specialist responds to a trouble code in your SUV’s computer in the same way. The code doesn’t say exactly what’s wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn’t need to look.

Now, you wouldn’t consider diagnosing yourself with a serious medical problem; good medical advice — unless you’re a doctor. So you shouldn’t consider trying to diagnose your vehicle’s troubles by yourself; good auto advice — unless you’re a trained mechanic.

There are cheap scanners available on the market and some Ashland auto parts stores offer to read trouble codes from your SUV engine computer for you, but these are really not good alternatives to taking your vehicle to a qualified service center such as Duffy’s Repair Service in Ashland. Your engine’s computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can’t read an engine computer’s long-term memory nor can they interpret manufacturer – specific codes. That’s why manager Billy Duffy at Duffy’s Repair Service spends a lot of money on high-end diagnostic tools.

It’s as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Richmond auto parts store isn’t really a money-saver, either, unless you’re a trained mechanic. You’ll end up with a code that tells you a symptom. What usually happens next is that the Richmond parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It’s actually cheaper to just go to the Duffy’s Repair Service in Ashland and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it won’t help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good car care is knowing where you can get a problem fixed, and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let’s do it right the first time at Duffy’s Repair Service. In the long run, it’s actually the less expensive choice.
