And cargo ships typically have a pair (or more) of giant diesel engines turning the props. Diesel engines are under the hood of almost every vehicle used on a construction job site. They are ubiquitous in environments where work must get done reliably—day after day. John Barta is the assistant chief engineer for GM’s 3.0L Duramax diesel engine. How durable are Audi diesel engines? Are the 2.0 TDI Audi engines trustworthy? About Trey; Audi diesel or gasoline: which is superior? Are TDI engines trustworthy? How long do TDI engines in the Audi A3 last? How Long Do the Brakes Last? How Long Do the Tires Last? How Long Do Audi A3 Engines Last? What are the drawbacks of diesel vehicles? What is the average expected lifespan of this car (in miles)? 360. Asked by audibob Mar 18, 2007 at 02:26 AM about the 1999 Audi A4 2.8 quattro Sedan AWD. Question type: General. This article applies to the Audi A6 C5 (2008-2015). When it comes to the Audi A6 C5, there is absolutely no getting around it. You will need to follow the general maintenance schedule and stay on top of any needed repairs as they arise. Doing so will not only ensure your car reaches 100,000 (or more) miles on the odometer, but, in some cases The other thing that effects how quickly an engine wears out is how much "slop" there is between the moving parts. This determines how long it takes the engine to rattle itself into oblivion. Today's engines are built to much stricter tolerances, and have much less "slop" than engines built in 1978. Two other factors favor today's engines. So a 100k diesel, for me would be more of a risk than a standard petrol motor, the diesel is usually nicer to drive than say a 1.6/2.0 petrol, think the economy thing influences a lot of people The third and final reason why diesel engines will last longer than gasoline engines is in how they are used. A diesel engine will push about 1300-1600 RPMs vs. a gasoline powered engine will do 2500-3500 RPMs. That means a gas engine is doing roughly two times the amount of revolutions per minute than a diesel engine. Audi updated waterpump/thermostat since facelifted models, but I'd probably replace those and supercharger oil. Also, planning to replace all gear fluids. As everyone said, maintaining is the key to keep this car for a long period of time. Last Audi I had was 2006 A4 2.0T and it ran fine until torque converter went bad at 130k mi. For the vehicles in Car and Driver's long-term test fleet, those intervals range from 6000 to 16,000 miles Doing that will help your car run properly and your engine last longer. A gasoline-powered vehicle can typically operate for around 200,000 miles before it needs a serious overhaul, or be replaced with a new vehicle. But an amazing fact is that diesel engines can run for 1,000,000-1,500,000 miles before needing any major diesel repairs. If kept well-maintained, a diesel engine can be driven for about 30 years or more. sFaBsPe.
