Turbocharger or supercharger failure on the 2001 Volkswagen Passat
Only 4 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When turbocharger or supercharger failure gets reported
There are 4 reports of turbocharger or supercharger failure on the 2001 Volkswagen Passat, 4 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 95,000 miles. It is the 30th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 68,500 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $1,500–$4,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 9 model years of this car. It shows up earliest on the 2000, at a median of 100 miles, and latest on the 2001 at 70,000 miles.
By volume the 2013 carries the most reports, with 38; the 2001 has 4. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
I own a 2001 1.8 turbo vw passat with give or take 57,000 miles. The 1.8 turbo has an issue with oil sludge. While researching this issue I have discovered that this is not an uncommon problem with the 1.8 turbo and have concluded that this issue seems to be a manufacturing defect. Accordingly, vw has extended the power train warranty. I have records showing that all of my oil changes were done within a timely manner. However in two instances I exceeded the "recommended maintenance": in the first case it was by 26 miles and in the second case it was approximately 290 miles. If vw has denied my claim due to those situations, they should not state in the warranty that the owner follow the "recommended maintenance" schedule but that the owner should follow a "required maintenance" schedule. I would also like to point out that a 2001 car, that cost over $22,000, that has been taken care of, and has less that 60,000 miles, such as mine, should not have engine failure. Even if I went over the "recommended maintenance" by 500 or 700 miles, which was not the case, the engine should not give out. Vw needs to take accountability for this…
'recall campaign' issued for volkswagen passat 2001, oil sludge warranty extension. *bf the vehicle broke down on the highway without any prior indications of problems, the oil and engine lights illuminated and the engine began making a screeching sound. The vehicle was towed to the dealership where they determined the engine had locked up from lack of oil. The warranty department refused to authorize the warranty coverage for the repair, because the consumer could not provided receipts from an automobile service company documenting that he had the oil changed regularly. The warranty dept. Stated the consumer was not entitled to warranty coverage for the engine and the turbo charger repairs. (lawyer on behalf of consumer) *jb
I am the owner of a 2001 vw passat with 65,000 miles. I have owned approx 6 - 7 cars in my lifetime and have taken care of them the same. Never have I experienced this with a dealer who requires all receipts. I was unable to locate 2 receipts and therefore was given the verdict of a $9000 bill to replace the 1.8 turbo engine. I am seriously appalled. My feeling that that the dealers are aware of this problem need to take some responsiblity rather than pour this in the lap of the owner. I would even think that they would consider 50 to 70% of the bill. I had to purchase another car thereby have two car payments because I cannot afford $9000 and needed to get to work and child to school, etc. I will never suggest this car to anyone!!

How far this goes
This page is kept out of search results because 4 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 4 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does turbocharger or supercharger failure happen on the 2001 Volkswagen Passat?
Across 4 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is turbocharger or supercharger failure on the 2001 Volkswagen Passat?
4 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
