Throwback Thursday: BMW and ALPINA

When most people think of high-performance BMWs, they think of BMW M. But ALPINA has been creating its own unique versions of BMW vehicles since 1965, combining performance, luxury, and comfort.

While Europe received numerous ALPINA models, only a select few officially made it to the United States.

Some of the most memorable include:

- 2003 ALPINA Roadster V8:** Based on the Z8, with only 555 produced worldwide.
- 2007–2008 ALPINA B7:** A supercharged 4.4L V8 producing 500 horsepower.
- F01/F02 and G12 ALPINA B7:** Twin-turbocharged V8 luxury sedans.
- ALPINA B6 xDrive Gran Coupe:** A rare combination of V8 performance, all-wheel drive, and luxury.

With their unique powertrains, distinctive styling, and limited production, these vehicles remain something special for BMW enthusiasts and technicians alike.

Have you ever worked on an ALPINA? Which model would you want in your garage?

Tech Tip Tuesday: Don't Overlook Connector Pin Tension

When diagnosing an intermittent electrical concern, it's easy to focus on the wiring, sensors, or control modules. But sometimes the problem is right at the connector.

A terminal can look perfectly fine during a visual inspection but still have poor contact tension. This can cause intermittent faults, communication issues, or components that work one minute and fail the next.

When checking connectors, don't just look for corrosion or damaged wires. Inspect the terminals for signs of spreading, overheating, or improper repairs.

Using the correct terminal test tool, check for proper contact tension. Never force an oversized test lead into a terminal, as this can create a problem that wasn't there before.

A little extra time inspecting a connector could save hours of unnecessary diagnostics and prevent replacing a perfectly good component.

Have you ever chased an intermittent fault that ended up being nothing more than a loose terminal?

🔧 Throwback Thursday: The Evolution of Automotive Oscilloscopes

Long before we had modern scan tools and laptop-based oscilloscopes, technicians were already using scopes to diagnose vehicle problems.

By the 1960s, large engine analyzers from companies like Sun Electric and Marquette were being used to examine ignition waveforms. These machines were often the size of a refrigerator and allowed technicians to compare ignition patterns, identify misfires, and diagnose problems that couldn't be found with a basic meter.

As vehicle electronics became more advanced, oscilloscopes became even more useful.

In the 1990s, Snap-on helped bring electronic waveform testing into a more portable format. Tools like the original Vantage combined a graphing multimeter with vehicle-specific diagnostic information. Later, Snap-on's MODIS brought scan-tool functions, lab scope capabilities, and component testing together in one handheld diagnostic platform.

Around the same time, another company was taking a different approach.

Pico Technology was founded in 1991, initially developing PC-based oscilloscopes. In 1997, Pico introduced its first automotive oscilloscope, the ADC-101, followed by an automotive diagnostics kit in 2002.

Instead of building everything into a dedicated handheld tool, Pico used a computer to display, capture, and analyze waveforms. That approach helped pave the way for the powerful laptop-based diagnostic scopes we use today.

Now we're using oscilloscopes for far more than ignition systems. CAN and LIN communication, injector current ramps, crankshaft and camshaft correlation, pressure transducers, and intermittent electrical faults are just a few examples.

The equipment has changed dramatically, but the principle hasn't.

A scan tool tells you what the control module is reporting. An oscilloscope lets you see what is actually happening on the circuit.

Who remembers using the old Sun engine analyzers, Snap-on Vantage or MODIS, or the early PicoScopes?

What was the first oscilloscope you used in the shop, and what are you using today?

Training at German Car Support Goes Beyond German Cars

German Car Support may have “German” in the name, but our training isn’t limited to BMW, MINI, Volkswagen, and Audi.

We’re continuing to expand the training side of GCS to cover the things technicians and shops are seeing now, and what they’ll be seeing more of in the future.
That includes Tesla-specific training, like the Intro to Tesla training shown in this video, along with AI training focused on practical ways shops and technicians can use these tools in the automotive industry.

Of course, we’re still continuing to build training around what we do every day at GCS, including BMW/MINI and Volkswagen/Audi diagnostics, systems, service information, and factory tooling.

The vehicles are changing. The tools are changing. The way we diagnose and operate our shops is changing too. Our goal with GCS training is to help technicians keep learning and stay prepared for what comes through the door next.

What training would you like to see us offer next?

🔧 Throwback Thursday: When Volkswagen Built the Phaeton

In 2002, Volkswagen did something completely different. Instead of building another affordable family car, VW stepped into the luxury segment with the Phaeton.
The Phaeton made its world premiere at the Geneva Motor Show in March 2002 and was packed with technology that you might not have expected to find behind a Volkswagen badge.

The Phaeton was packed with technology and offered some serious engine options, including the W12. In the U.S., buyers could choose between the 4.2L V8 and 6.0L W12.
The Phaeton was also built in Volkswagen's Transparent Factory in Dresden, where the cars were assembled largely by hand. The facility was so unusual that the production floor incorporated wood flooring, and employees worked in white clothing, with many wearing gloves.

What made the Phaeton interesting was that it still wore a Volkswagen badge despite competing with luxury sedans from Audi, BMW, and Mercedes-Benz. Underneath, it also shared architecture with the Bentley Continental GT and Flying Spur.
Volkswagen's Dresden factory actually produced 2,186 Bentley Flying Spurs during 2005–2006 and 2013–2014 alongside its Phaeton production activities.

The Phaeton was an impressive car, but it was also incredibly complex. Anyone who has worked on one knows there is a lot more hiding underneath that understated exterior than you might expect from a Volkswagen.
U.S. sales only lasted a few years, but production continued in Europe until 2016.
Who has actually had a Phaeton in their shop? And would you want to own one today?

🔧 Tech Tip Tuesday: Verify the Concern Before You Diagnose It
Before getting deep into testing, take the time to verify exactly what the vehicle is doing.
Don’t rely only on the customer’s description or the fault codes. Drive the vehicle if possible, operate the system yourself, and try to duplicate the concern under the same conditions.
Knowing when, how, and under what conditions a problem occurs can completely change the direction of your diagnosis.
A fault code tells you what the control unit detected. It doesn’t always tell you what the actual problem is.
Verify the concern first. Diagnose second.
