►Whether attached to a gasoline engine or a diesel engine, your Volkswagen's DSG transmission will need regular servicing. Its lubricating fluid is also the hydraulic fluid used for actuation, so it needs to be kept clean and healthy to prevent any issues. VW recommends a 40,000-mile service interval for the fluid and filter. Driving beyond that can lead to missed shifts, harsh engagement, and eventually clutch pack failure. Luckily, servicing the DSG transmission is pretty straightforward. Servicing the DSG in the B7 Passat is the same process as it would be in most other VWs from that era w…

►The front brakes on your VW Passat account for a bit over 50% of its braking capability. As such, they're likely to wear before the rear pads and rotors. Most likely, the brake pad wear sensor will trip, alerting you that the pads are low. However, brake pads and rotors can wear out before then, causing deep grooves in the rotor face or warped rotors. Replacing the front brake pads and rotors on a B7 Passat is very straightforward. You'll need a few hand tools and a free afternoon, but not much else. It's a perfect DIY for a beginner, too, so don't be afraid to tackle it yourself. In this vi…

►Diesel engines don't use an ignition system; compression is the sole catalyst for ignition. However, they do use an electrically powered component that's positioned in the combustion chamber, like a spark plug. In this case, diesel engines use glow plugs to heat the chambers. Cold weather makes starting a diesel fairly difficult, and the plugs are meant to assist with that. If damaged or incorrectly functioning, you may have trouble starting in cold weather. Glow plugs don't have a specific replacement interval and can last well beyond 100,000 miles without issue. It's case-dependent, so rep…

►Diesel engine oil is not comparable to gasoline engine oil. While their lubricating bases are similar, the additives are completely different to support the vastly different needs of a diesel engine. The latter needs far more detergents to cut down sludge and low-SAPS to play nicely with modern diesel emissions. Sulfated ash in older oil blends can wreak havoc on DPFs, destroying thousands of dollars in parts, so you must ensure your oil is the right specification. Volkswagen developed its 507.00 standard for modern DPF-equipped diesel engines. It's made for longer drain intervals with more…

►The MAF sensor is critical to a well-running engine because it gives the engine computer the precise air-intake values it needs for fueling calculations. Even a slight variation can throw its performance and fuel economy completely out of whack. It's a common failure point on 2.0L TDI engines, and while there isn't a strict manufacturer service interval, we typically see these sensors begin to fail between 80,000 and 150,000 miles. Replacing the MAF sensor on your TDI engine is a very simple process. You'll need to unclip some plastic and remove a couple of screws, but that's about it. You c…
