The OBD is short for On-Board Diagnosis, a diagnostic protocol that keeps track of vehicle operation. When the car is running, its control modules monitor how each system performs. They do this using a range of sensors, and when their values are out of predetermined range, the vehicle warns a driver with a corresponding warning light. In addition, a trouble code is stored within the control module. All cars from 1996 onwards have the OBD2 system integrated into their structure. However, accessing these trouble codes is only possible with a scan tool, which hooks up to the OBD2 port.

Over the years, we have been using almost every OBD2 scanner brand that exists to diagnose vehicle problems. Everything from the cheap ELM327 adapter, FIXD sensor, Autel, SnapOn, TopDon, and even dealer-level scanners such as MB Star. We quickly realized that choosing the best OBD2 scan tool can be confusing even for auto mechanics and vehicle owners looking for a good DIY scanner.

After testing too many OBD2 scanners, we were frustrated with at least one of these issues:

1. Limited Control Unit Coverage – The scanner can only diagnose engine, airbag, transmission, or ABS but not other systems.
2. Only One Vehicle Brand – Supports all system diagnostics for one make and model. If you need to diagnose other vehicle brands, you must pay more.
3. No Bidirectional Support – The scanner does not allow you to test components or sensors. For example, if the vehicle is equipped with air suspension, you can not activate the compressor with the scanner to perform testing.
4. Yearly Update Fees – The scanner requires a yearly subscription, or you must pay to update.
5. Speed – The scanner is too slow to scan vehicles and read and clear codes.
6. No Support – No tutorials on how to use the scanner. Lack of slow response from the support team.
7. Price – Because many users are unfamiliar with scanners and what they can do, we found that scanners with limited functionality were often overpriced.

Vehicles today need a lot of attention and good OBD2 scanners that can diagnose various control units. The check engine light codes are stored in the Engine Control Unit (ECU), which is only one of over twenty control you are found on your vehicle. This is why an excellent diagnostic tool needs to do more than just read and clear codes that trigger the warning light. Therefore, we decided to focus this article on diagnostic scan tools that can diagnose all the systems in your vehicle and others that offer the best value for the money.

Best OBD-II scanner – our picks

1. YOUCANIC Full System Scanner

The YOUCANIC scanner allows car owners and automotive technicians to read diagnostic trouble codes for any control unit found on the vehicle. In addition, it will enable the vehicle owner to take vehicle maintenance and troubleshooting into their own hands. Not only can you read and clear codes from any control unit on any vehicle make, but you can also view live data. This scanner provides bidirectional support that other scanners provide on diagnostic scanner models when you spend over $1000. Bidirectional support allows you to use activate solenoids or pumps to diagnose a problem, just like a dealer tech can.

The YOUCANIC scanner plugs in directly to the diagnostic OBD2 port under the driver’s dashboard. The scanner is hard-wired instead of using a Bluetooth dongle. A rugged handheld scanner that fits the needs of professional mechanics while still being affordable enough for DIYers.

2. Autel MaxiCOM MK808

Next, we come to Autel, which is one of the most famous names in the business. Their devices are praised for their performance and versatility. The latest model in the MaxiCom range, codenamed MK808TS, doesn’t fall short. It offers almost any feature a professional or DIY mechanic may need. This includes access to all control modules, live-data monitoring, and bidirectional testing. Additionally, there are also things like service reset and sensor programming.

With a 7-inch touchscreen display, this scanner is smaller than other similar devices from Autel’s range. But this doesn’t have to be a drawback, as it makes it less bulky to use. The pop-up stand at the back adds to the practicality, allowing the device to be mounted on the dashboard. The manufacturer is particularly proud of the scanner’s TPMS feature, which is the same as in their popular TS601 TMPS tool.

There are some drawbacks, such as the image quality, which may be a bit low for some. In addition, the IMMO function, which resets the Anti-Theft system or relearns the keys, doesn’t work well with some European cars. And over $700 is a bit more expensive than a YOUCANIC scanner.

3. LAUNCH X431 V Pro

Like Autel, Launch is a big name in diagnostic equipment. We have included their X431 V Pro in this selection, as many experts favor it. This is the largest device on the list, with a 10-inch touch-sensitive display that shows an image in high-definition. It also has a pair of cameras, back and front, just like most tablets do. Predictably, this scan tool gives you access to all vehicle modules and is bidirectional, like the other two.

But here’s the X431 V Pro’s party piece – this scan tool can calibrate ADAS on most makes and models. This can be helpful, as these semi-self-driving systems are becoming more frequent in modern cars.

The downside of this diagnostic device is its price, which is approximately $900. This makes it almost twice as expensive as the Youcanic scanner. For the extra money, all you get is ADAS support and a crisp display.

Types of OBD2 scan tools for home mechanics

There is a wide range of automotive diagnostic tools on the market, each offering different capabilities, and features. But also, there might be a noticeable price difference between seemingly similar devices. This may create confusion when car owners try to decide which scan tool is best suited to their needs. So, to help out with this, we will go over three main types of car scanners.

OBD2 reader

This is a basic device that only gives access to drivetrain codes. With it, you can see what diagnostic code has triggered the check engine warning light and erase it. In addition, many of them will allow you to monitor the live data. But anything else, like the ABS or Airbag systems, is beyond their reach.

Vehicle-specific OBD2 readers

These are more powerful versions of the previously mentioned devices. Their main upside is the ability to access all vehicle modules and read check diagnostic codes. Carly OBD2 Bluetooth or BlueDriver Bluetooth adapters are an excellent example here. On the downside, these scanners usually work with one particular brand only.

Diagnostic tools

This type of equipment gives a professional level of insight into the car’s infrastructure at a level of authorized repair shops. Apart from having access to all modules and stored codes, they can also start various diagnostic procedures. This bidirectional support allows you to test components and pumps to narrow down the problem and avoid misdiagnoses. Professional diagnostic tools will work with most makes and models, but some exemptions may exist.

Conclusion

OBD2 scanners are an absolute must-have for any car enthusiast nowadays. Not only will they give a quick insight into what triggered a warning light, but they will also help solve it. However, there are all sorts of devices on the market, ranging from those with limited options to very capable but expensive ones. But with YOUCANIC full system scanner, you’ll get dealer-lever diagnostic support at an affordable price. This makes it the best scan tool all around.

The year 2018 is a special year for BMW, given the celebration of the legendary M3 Convertible first released on the market in 1988. And for that, the carmaker decided to bring it a tribute by launching a special and limited edition – the all-new BMW M4 Convertible 30 Jahre.

Not everybody will get to enjoy this special edition, as it will be offered in just 300 units worldwide. Unfortunately, rumors state that it won`t arrive in the United States, but might be offered instead in a small number of examples in Australia.

The BMW M4 Convertible Edition 30 Jahre comes standard with the M Competition package, meaning plenty of high-end visual tweaks and gizmos inside the cabin.

The car`s first striking elements at the exterior are the gorgeous and exotic Macao Blue or Mandarin II with BMW Individual High Gloss Shadow Line trim, and adding as well the exclusive 20-inch alloy wheels with matte Orbit Grey finish.

With the M Competition Package, customers also get the M Sport exhaust system or Adaptive M Suspension with SPORT mode, and direct steering ratio.

Inside, the cabin looks exclusive, first with “30 Jahre Edition” badges on the door sill plates, adding as well carbon fiber trim, special floor mats, full Merino leather on the seats, yellow contrast stitching, and much more.

Back in the 1988, the BMW M3 Convertible came out with a 2.3-liter naturally-aspirated flat-four engine, with 143 kW. It later on evolved in a six-cylinder mill in the E36 and E46. Today, we are glad to witness the advancement BMW has made in the engine department. Thus, the recently unveiled M4 Convertible Edition 30 Jahre is now in state-of-the-art form, coming equipped with the famous 3.0-liter inline six-cylinder twin-turbo engine, delivering 450 horsepower (331kW).

Prices and availability on the market will be announced perhaps at the 2018 Geneva Motor Show, where the model is expected for an official show-off. Meanwhile, you can admire the BMW M4 Convertible Edition 30 Jahre in the media gallery below!

After 13 years of presence on the market, the British luxury Rolls-Royce manufacturer has recently decided to end production of the exquisite Phantom VII, due to poor sales and not the best appreciation from Rolls-Royce fans.

With the latest model to be commissioned by a Rolls-Royce famous enthusiast, the model has undergone a serious of modifications which makes it stand-out from the crowd.

We are looking here a long-wheelbase model, finished in Blue Velvet, this bespoke model coming as well with a twin coachline with an ocean liner motif, adding as well a silver Spirit of Ecstasy and pinstripe rubbers.

The interior complements the car`s wrap with the same Blue Velvet colour, with new styling elements also to be added. We are looking here at two clocks which can be rotated in both direction, depending on the car`s position on the globe.

Other features inside also refer to a hand-cut wake effect on the lambswool carpets, high-end materials and leather on the seats and dashboard, and so on.

In the engine department, the Rolls-Royce Phantom VII features the same 6.75-liter naturally aspirated V12 engine, with 459 horsepower and 720 Nm of torque, allowing an acceleration from 0 to 100 km/h in just 6.2 seconds, at a top speed of 240 km/h.

As for the car`s pricing, there are no details released on that matter yet, but we expect a seven-figure price, especially since a stock model used to cost at least £470,000 in the United Kingdom. Enjoy the media gallery released with the last Rolls-Royce Phantom VII!

Ever since arriving on the market a couple of months ago, the all-new G30 2017 BMW 5-Series in all its forms has been long presented and debated. However, there was a particular model that hasn’t received the best appreciation and that would be the all-new 2018 M550i xDrive, presented with lots of admiration and good thoughts.

For those who haven’t had the chance of hearing about the gorgeous M550i xDrive are now having the chance of seeing it in full action, with a muscular design, exquisite interior and a potent engine under the hood.

As we already know from the carmaker`s announcement about a month ago, the future M550i xDrive is the hardcore version from the 5-Series, now being equipped with an infusion of M Performance Parts, both outside as well as inside.

One can depict the new kidney grille frame, M Performance accents on the front air intake, two Air Breathers on the front fenders, finished in Cerium Grey metallic, adding as well bespoke mirror caps at the exterior, trunk lid, high-gloss Shadow Line trim on the windows, black chrome tailpipes and so on.

Inside, the cabin has received the same high-end treatment, now enjoying the plethora of high-end features from the same M division. The most outstanding tweaks refer to the Black Dakota leather with blue contrasting stitching seats, M Sports steering wheel, M design floor mats or aluminum pedals.

All these ads the latest safety features, such as the Active Driving Assistant Plus, Evasion Aid, Active Lane Keeping Assistant, as well at the Active Cruise Control (ACC) with Stop & Go feature. Under the hood, the all-new 2018 BMW M550i xDrive adds a powerful 4.0-liter twin-turbo with 456 horsepower and 480 lb-ft of torque, allowing an acceleration from 0 to 100 km/h in a mind-blowing 3.9 seconds.

It’s no longer news to talk about BMW’s plans for finally bringing the X1 over the Atlantic. Just how ambitious that plan is this time is quite the different story.

The New York Auto Show unveiling of the facelifted version is a given. That’s the version that’ll hit the U.S. market and they’ve even determined when.

Usually when a car debuts at a car show, it’s customary for it to hit the market some six months later. Not this time though.

The 2013 BMW X1 will be in US showrooms as early as this summer. It’s a rather ambiguous term but it does mean that the launch will happen considerably earlier than the six month norm.

Though it’s appreciated, let’s not forget that the BMW X1 has been delayed for the US market so many times before that plenty of people will have certainly lost interest.

At least we can now put this “unfair” situation behind us and us annoying Europeans won’t have anything to lord over the consumerist Americans.

Or do we have something called the M Performance diesels? I suppose we do. Actually, we have just about all diesels since the 2013 X1 will not get them stateside either.

Still to be confirmed but most bets like on the Yanks receiving the N20 turbocharged four cylinder engine.

It may not be the most glamorous powerplant around but it does develop 245 horsepower and 258 lb-ft of torque and yet won’t chew through fuel. Well at least it won’t do so like other American vehicles.
