Volkswagen Passat Prone to TDI Engine Failure in Woodinville

TDI EngineWe have talked about TDI engines in prior posts. They’re a common engine type in most German automobiles. The engine, even with its general and stellar reliability, has been known to experience issues. TDI engine malfunction in the VW Passat has been known to occur. If you own this popular family sedan, remain alert for signs of problems and take the car to a VW and Audi shop if you notice performance irregularities.

TDI Engine Failure in Woodinville: Signs to Watch For

In 2012 to 2014 models, owners have complained of turbine issues in the 2.0 TDI diesel engine. This is particularly the case not long after having their vehicle serviced. Engine trouble has also been reported in fairly new cars that haven’t even reached 1,000 miles on the odometer

Owners have often noticed these symptoms before the engine croaked:

  • A sound akin to a train whistling
  • The sound of a peanut rattling inside a tin can
  • A sensation like the engine is free-wheeling and not in tandem with the actual boost

A Second VW Passat Issue

Most VW cars also use a direct-shift gearbox (DSG) transmission. Owners have noted a sound reminiscent of grinding metal during second or third gear. This most often occurs when it’s really hot outside. Typical solutions include a synthetic oil change or even a full mechanism swap. Unfortunately, the issue has been reported to continue even after the fix.

Bring Your Vehicle to a Specialist

As you can see, it’s fairly common for Passat owners to experience the same issues even after professional repairs. This is why it’s important to bring your Passat to a VW and Audi repair shop like Buttera Motors. Our story explains why we’re Kirkland’s go-to German auto maintenance team.

Anti-Lock Brake Repair for Your Audi Near Redmond

Anti-Lock Brake RepairThe brakes on a vehicle appear straightforward: you apply pressure on the brake pedal, and the car comes to a stop. The brake component, though, is quite sophisticated, particularly with respect to anti-lock brakes that are commonplace in most modern Audi models. This is why anti-lock brake repair is best left to an Audi & VW repair professional.

How Anti-Lock Brake Systems (ABS) Work

Most recent-year Audi models use a disc brake with an anti-lock brake. The disc brake is conventional in most vehicles and uses brake pads to squeeze the rotor. The power is transferred hydraulically, leading to friction between the disc and pad to bring the wheel to a halt.

Newer Audi vehicles also have anti-lock brakes to improve gripping on slippery roads. An ABS uses rapid pumping motions to engage the wheels as they lock up. This reduces speed while the driver maintains control even under highly slippery roads. An ABS utilizes an advanced computer that includes sensors, electronic control units, and hydraulic actuators. These parts all operate in tandem to monitor the motion of each tire. Continue Reading →

A Look Into Audi’s History Near Kenmore

buttera-4

Do you know what makes the Audi the beloved brand it is today? The Audi history spans over 100 years to the dawn of the first automobiles. If you’re a proud Audi car owner, then learn of the manufacturer’s history. When you appreciate the history, you’ll also come to realize the importance of Audi servicing to keep your car in tiptop shape.

Audi History at a Glance Near Kenmore

It all began in 1899 when August Horch founded the company Horch & Cie, in Cologne, Germany. This was where Horch manufactured the first vehicle. He would later start a second company. Since his last name was already used for his first company, he would use the name Audi, which was the Latin translation of his surname.

The Origin of the Four Rings

Audi’s four interlinked rings have quite a history of their own. In 1932, the brand formed a joint venture with three other automotive brands: Horch, Wanderer, and DKW. The four rings symbolize each of these manufacturers. The partnerships of the brands together became known as Auto Union AG. Continue Reading →

All About Audi’s TFSI Engine in Bothell

buttera-motors-6Some German vehicles are known for their Turbo Fuel Stratified Injection engine (TFSI). We discussed this in detail in a previous post, which you can read here. Audi also has a variant of this engine, available for the next-generation A4, released in 2015. Learn about the Audi TFSI engine and its unique combustion delivery method.

The Inner Workings of TFSI Engines

German automobiles require upkeep and tune-ups from a VW & Audi service. The TFSI engine is no different. The Audi A4 produces up to 190 hp and 236 lb-ft of torque. This is due to a new combustion deployment that works in the same style as the Miller cycle.

The Miller cycle uses a supercharger and an intake valve that stays open during the compression stroke. This leads to about a 15% boost in engine performance.

The difference, though, is in the crank angle that has been lowered from 200 to 140 degrees. A bigger boost pressure on the inlet side has also been incorporated. This minimizes the engine’s intake time without lowering its cylinder charge. With a better combustion cycle, the A4 provides a drastically improved compression ratio. In addition, the engine fully warms up in less time and also experiences significantly less friction.

Common Problems for 4 Volkswagen Models in Kirkland

buttera motorsCertain automotive manufacturers and models are known to have specific problems apart from the standard wear and tear. Volkswagen vehicles are no exception, which is why it’s pivotal that you’re cognizant of issues reported by other owners of the same model and year. Here are four common Volkswagen problems for the Jetta and Passat that have been brought up by those who have owned or leased either of these models.

1. 2013 Jetta Hybrid

The check engine light is known to flash on for the 2013 Hybrid Jetta. This has typically been so for those that are still relatively new with just several thousand miles under their belt. If the light abruptly comes on, bring your vehicle to a VW & Audi service.

2. 2004 Passat

Those who drive the 2004 Passat have reported coil failure, usually when the car hits 75,000 miles, give or take several thousand miles. The coil sends power to the spark plug, and a worn coil can lead to stalling and decreased engine output. Continue Reading →

Maintain the Catalytic Converter on Your German Car in Bellevue

buttera-3-2016If your German car didn’t pass the last emissions test, then bring it to a VW and Audi repair center to find out why it failed. Due to the intricate parts and construction, it’s easy for a general mechanic to get the diagnosis wrong. For German vehicles, the issue is often connected to the catalytic converter. Maintain this auto part, and emissions testing should be a clear pass every time.

Why Catalytic Converters Fail

Catalytic converters wear out for multiple reasons. A typical cause is an incorrect fuel mixture. This creates too much heat, causing the catalyst to melt. Subsequently, this leads to deposit accumulation that inhibits airflow. In addition, the melted metal also leads to a gaseous buildup in the exhaust, causing the vehicle to stall.

Besides stalling and emissions test failure, here are several additional signs of a faulty converter:

  • The car won’t start
  • A significant loss in acceleration
  • Reduction in fuel efficiency
  • The Check Engine light switches on

If you have the skill, you can conduct a DIY evaluation. Pull out the oxygen sensor from the exhaust system and drive the car around the neighborhood. If there’s a noticeable change in handling, then the catalytic converter is probably clogged. Continue Reading →

Understanding the Warning Lights on a VW Vehicle Near Woodinville

buttera motorsModern VW vehicles use an array of warning lights to inform you if a specific issue arises. This provides a more accurate indicator than a generic check engine light. However, if you don’t often review the vehicle user manual, you can easily forget what the VW warning lights mean. Here’s a guide for a quick reference. Refer to your manual for images or more detailed explanations of each indicator.

Pull Over if any of These Warning Indicators Appear

  • Red brake light – low brake fluid
  • Red thermometer – engine temperature is dangerously high or coolant level is low
  • Red steering wheel – power steering failure
  • Liquid pouring out of bottle – failed engine restart
  • Yellow “!” with an oil canister – low to no oil pressure

TDI Engine Maintenance for the Winter Around Redmond

buttera motorsMost modern German cars contain a turbocharged direct injection (TDI) engine under the hood, hence why most VW and Audi repairs need care from a specialist mechanic. TDI engines are lauded for their ability to deliver enhanced combustion, power increase, and CO2 reduction. On the flip side, these engines are also known to have problems in cold-weather operations. Since Redmond isn’t known for extreme cold, this isn’t something you should be worried about. TDI engine maintenance, though, is still necessary if you own a vehicle outfitted with one of these bad boys.

Precautions for Winter Commuting

Diesel fluids react differently than gasoline under temperature fluctuations. When the temperature drops, the diesel fuel thickens. Hardened diesel is referred to as “gel.” Gel is sludge-like and can’t be pumped, causing the engine to shut down.

A way to minimize gel formation is to install an auxiliary heater. This keeps the engine warm and prevents a rise in fuel viscosity.

Apart from the engine, inspect the battery to be certain it’s fully charged. Batteries run less optimally in frigid weather. In addition, oil also thickens under low temperatures, thus forcing the battery to push even harder to get the engine to crank. Continue Reading →

Don’t Neglect Your Limited Slip Differentials Around Kenmore

buttera motorsMost modern German vehicles utilize limited slip differentials for bettering traction on slippery roads. It’s exactly for this reason that you need to bring your car to an Audi and VW service for tire checkup and alignment.

Limited Slip Differentials (LSD) Explained

Most American cars, particularly older models, use a standard differential where the left and right axle rotations are completely independent of one another. This creates an issue when one wheel drives over a slippery surface. This makes the wheel spin excessively while the other spins at a normal speed. This leads to more power flowing to the slippery wheel while power flow comes to a stop for the other. This leads to major shifting problems or even brings the car to a total halt.

A limited slip differential seeks to correct this issue by minimizing the independence between the two axles. Most LSDs use a clutch pack based system. It’s not necessary to know the precise mechanics of how the system works; all you need to understand is that the component includes friction and steel plates wedged between the casing and side gear. This allows the distribution of power so that one wheel absorbs the traction loss should the other wheel drive over a slippery road.

What to Do About FSI Engine Carbon Buildup Near Kenmore

buttera motorsAn awesome aspect of German automobiles is that most models utilize a Fuel Stratified Injection (FSI) engine. As suggested in its name, fuel is injected directly into the combustion chamber where it combines with the air entering from the intake manifold. The mixture is compressed and causes a spark that amplifies horsepower. Unfortunately, FSI engine carbon buildup is commonplace. Excess carbon causes restricted airflow and loss of power.

Symptoms of Carbon Buildup

If you notice signs of carbon buildup, then bring your vehicle to an Audi & VW repair center. Typical symptoms include:

  • Lack of engine response
  • Lag in acceleration
  • Lack of response when hitting the gas pedal
  • Check engine light frequently flashing on
  • Misfiring, which becomes noticeable when the engine revving noise sounds erratic
