How long do tdi engines last

AndyBees Top Post Dawg. The rear main seal is bone-dry I think the key to longevity of these engines is low RPM shifting at or below and of course, proper maintenance. Redlining the engine at every shift takes a toll over the duration and that holds true with any engine in my opinion. I've read a few posts down through the years about guys saying they would drive in-town expressway speeds in 4th gear hanging around 4, RPM Chazhill14 Well-known member.

I have k miles on mine and the last 50k were under high boost and I still have no oil consumption besides what is picked up in the intake out of the valve cover which is normal. The only annoying thing about mine is a very slight compression leak from one of the glow plugs but that's due to a retarded previous owner and not a longevity issue.

I don't usually shift after and my commute to work is 20 miles with 17 of them highway so that's easy on the engine as well. I change my oil and water separator ever k miles and that's pretty much the only maintenance I do on the engine because that's pretty much all it needs. Obviously you'll be changing things like bushings, lights, brakes, glow plugs TDIs in general, especially ALHs, are known to pretty much last forever so I think they are definitely worth putting money into them if you are going to maintain them.

Fun car to drive for sure and I am pushing for , minimum miles. Joined Feb 1, Location Covington, Ga. I have , miles on my engine that has never been serviced.

Of course regular oil changes, timing belts and water pumps. Original turbo but the fuel pump started getting wonky and was replaced. No idea if it needs head work. Probably does need a valve job but no signs that it does. No significant oil consumption. I do a lot of 1 hour or more driving which is easy on an engine. I also live in the south where there are few cold below freezing starts. It has k on it and never burns any appreciable amount of oil. Has been malone stage 3 for 50k miles.

I blew the original turbo by overboosting it failed vnt actuator. Now running along happily as ever. My has about K miles on the odometer. Got it as a salvage wreck at 34K from a roll over. Engine was damaged and replaced, so miles on that are unknown. The body won't last too many more years up here in the salt country due to extensive bodywork going bad. If I can find a decent chassis gas or TDI it may become a donor car. Hopefully finish that up in the spring. Last edited: Dec 30, Category: automotive green vehicles.

A well -maintained diesel engine can easily go , miles. Why are Volkswagens so cheap? VWs come at a cost. Why is TDI cheap? Why do diesel engines last so long? Is VW reliable? What does TSI stand for? How much is a Volkswagen Golf? Are Volkswagen expensive to fix? Do Volkswagens hold their value? Is Volkswagen better than Toyota? Are VW turbo engines reliable? Is Volkswagen a good car to buy? DPX 1, posts months. Still running in , up to , on mine 2 liter.

Diesel engines run at lower revolutions per minute RPMs and achieve higher levels of torque relative to a gas engine. Being able to operate at lower revolutions to achieve the same power means less wear on your pistons, rings, cylinder walls, bearings, valves, and guides which aids in lengthening the life of your engine.

Diesel engines are typically left running when not in operation for short periods in time. Since a large percentage of wear occurs at startup, the constant cycling of turning the engine on and off saves in wear over that of a gasoline engine.

It also reduces the heat cycles and keeps operating temperatures constant. They are not subjected to quick starts and stops. Starting the engine is one of the most abrasive acts on the motor.

While idling your motor is not ideal for its longevity, that is what most of these trucks are going through.
