You are reading this because you own the VW TDI diesel car with 45 MPG. 250K. Diesel engines have to be better built than any gas engine due to the incredible PSI internally they create. The fuel injectors operate at near 26000 PSI, and their turbo does not have bearings. To keep these two items in top shape because replacing is dire. 4000 (parts and labor). The fuel injectors can become clogged or not spray the pattern when new and when it happens, you will know it by how it runs. Likewise, if you suddenly have a ton of black smoke pouring out the rear end, your turbo has died. Usually, with periodic maintenance, both can last for the life of the car. The VW diesel engines love the highway. Love high speeds like on the autobahn. It helps clean them out from soot. Usually, the cars already use cleaner diesel, so the soot issue is no longer a real concern.
But again, it can be where the EGR is concerned. The turbocharger design on Volkswagen TDI engines does not use bearings. Rather, the turbocharger shaft floats on a small film of oil that coats the inner race of the solid brass bearing. A particle in that film will function as a piece of sandpaper and grind away the surface of the shaft and bearings. When this occurs, the gold plating begins to show and may be grooved. As time moves on, eventually the shaft will wobble and the turbo fan will impact the walls of the turbo, bending the blades or pitting the surface, which should be super smooth. The cheapest remedy is simply to change your oil and filter no later than every 10,000 miles. Changing every 5000 miles may required if dusty conditions exist. This is the prime reason to keep the engine with clean oil. Remember, the turbo has no bearings.
8). This will clean any soot that has gathered on injectors over the years. The process takes around 30 minutes and directly enters the fuel injectors from the can. Disable the fuel pump in the gas tank by removing the fuse for it. Locate the black fuel filter on the left side. There are four rubber hoses.Two come from the fuel tank and two connect to the fuel rod that supplies the it to the injectors. Disconnect the two from the fuel filter that connect the fuel rod. Insert to plastic tubing pieces into each end of the rubber hose and then insert the other ends into the can. Place the can in a secure place or have someone hold it with gloves. Start engine and run the engine for a few minutes at 1500, 2000, 2500, 3000, 3500, 4000 RPM. The can will get hot. Allow the engine to idle and continue it again. Make sure you watch how much cleaner is left. When done, reconnect the two lines to the fuel filter. That is it. If they were clogged at all, you should better idling and performance.

Engines are shrinking. From econocars to supercars, from pint-size roadsters to full-size pickups, engine downsizing is happening across the industry. This is not a sad story. While those output losses are not negligible, they have been largely offset by new transmissions with additional gears. A standard six-speed manual鈥攆inally! 鈥攐r optional eight-speed automatic has replaced the 2018 Golf's five-speed stick and six-speed autobox. Even better, despite the loss of power and torque, acceleration from a stop keeps pace with the last automatic-equipped Golf we tested, a 2018 Golf SE. The 2019 car reached 60 mph in 7.6 seconds (versus 7.7 for the 2018 model) and matched its predecessor in the quarter-mile at 15.9 seconds, its 88-mph trap speed lower by 1 mph. As with most other modestly powered cars, the 2019 Golf had us hammering the gas pedal pretty often during everyday driving. But unlike most other modestly powered cars, the engine didn't thrash and scream in protest when we did so. Nor did it boom at low rpm, as we observed in Golfs with the 1.8-liter and automatic combo. Only at the very upper reaches of the rev band does it start getting loud.
Generally, the 1.4T is uncannily smooth and quiet in most of its operating range鈥攁 few times we had to check the tachometer at stoplights to see if it was running. Our test car was a base Golf S model and rode on 195/65R-15 Bridgestone Ecopia EPA422 Plus tires, which could partially account for its 177-foot stop from 70 mph. That's eight feet longer than the 2018 Golf SE required; it weighed 158 pounds more but was fitted with more aggressive 205/55R-16 Hankook Kinergy GT tires. Despite its modest rubber, the 2019 Golf clung to the asphalt with 0.84 g of lateral grip, which is a tick more than the 0.83 g we observed with the 2018 car. That tiny improvement at the skidpad understates the impact a lighter nose has on handling. While we have long touted the Golf's steering as lively, it now feels even more eager to change direction and offers genuine tactility transmitted through the steering wheel's thin, leather-wrapped rim. It also continues to track as well at high speeds as an Audi costing twice as much.
