How a Bad Timing Chain Can DESTROY Your 2.0L Turbo Audi

2015 Audi Q5 Timing Chain Issues

Known for having timing chain issues, this 2015 Audi Q5 was on the brink of catastrophic engine problems prior to this repair.

Used cars can be a major headache, as many of us are well aware, constantly needing pricey maintenance and repairs once they reach a certain point in life. This has become increasingly true in recent years, as new vehicles continue to get more and more complex and employ more electronics and fancy wizardry designed to extract both performance and efficiency while meeting emissions standards. In the case of the 2015 Audi Q5 that that recently rolled into the shop of YouTuber David Long – or the Car Wizard, as he’s otherwise known – he managed to find a major issue that could have resulted in a total engine failure before that actually occurred.

The turbocharged 2.0-liter Audi/VW engine present in this 2015 Audi Q5 certainly has its fair share of known issues, as Long discusses in this video. In this case, timing chain problems have reared their ugly head, which was diagnosed by a long cranking time, as well as the fact that the crossover ran rough once it did start. This is a common problem that Long deals with all the time, so it wasn’t difficult for him to figure out what was wrong with this customer’s Q5, at least.

Long also found that the fuel rail pressure was too high, which is yet another symptom of stretched timing chains. When it gets to a certain. point, it causes issues with the high pressure fuel pump since it’s ran off the camshaft at the back of the engine. In this particular case, the timing chains have stretched so badly that engine damage was very likely to occur soon, so the owner obviously brought it in just in the knick of time.

Luckily, this problem isn’t horrifically expensive to fix, with Long noting that it costs around $2,000 to rectify – however, rebuilding or replacing the engine is obviously a far pricier proposition. The good news is, a new timing chain kit will last an easy 100k miles, as Long notes, so if you have an Audi equipped with this engine and you’re experiencing problems starting and a rough idle, it’s probably best to get it done as soon as possible.

Brand New Audi RS6 Drops Valve With Just 450 Miles on the Clock

2022 RS 6 Avant

After suffering the catastrophic failure, this Audi RS6 needs a new long block, because the old one is quite literally toast.

When one buys a new vehicle these days, one typically expects to be able to rack up quite a few miles before worrying about things like routine maintenance – let alone actual repairs. However, from time to time, we come across some horror story on the internet about a brand new car that suffers some sort of serious mechanical issue, and in a few cases, something as extreme as a blown motor. Sadly, that’s precisely what happened to an Audi RS6 owner recently when their hot wagon had to be towed to the shop with just 450 miles on the clock.

The YouTube channel Just Rolled In documented this particular issue recently after the Audi RS6 was dropped off for repairs. The owner stated that he heard a snapping noise while driving down the road, after which the car made a clanking noise and shut down completely. Our mechanic immediately knew what the problem was – a valve dropped down into the cylinder, which is obviously a pretty bad thing for any car, let alone one with just 450 miles.

In a follow up clip, we get a closer look at the engine’s internals, where the piston has completely melted, while the cylinder walls are gouged up as well. We can only see one valve in the borescope view, but as our host points out, this engine is “completely torched,” and filled with various debris to boot.  In fact, the mechanic is able to travel through the piston to check out the connecting rod, which is both humorous and kind of sad at the same time.

@mk6_matt Tried to do a quick voiceover of the carnage from this RS6. New crate longblock is already on the way #rs6 #V8TT #seized #avant #audi #fyp #voiceover #boroscope #snapon ♬ original sound – Matt

It’s unclear what caused this horrific destruction in the first place, whether it be a defective engine or simply extreme abuse by the owner, but ultimately, this brand new motor is toast. The mechanic has already ordered a replacement long block, which will help get the hot wagon back on the road, but in the meantime, it’s little more than a pricey paperweight.
