Turbocharger or supercharger failure on the 2002 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 5 reports of turbocharger or supercharger failure on the 2002 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 34th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 46,167 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 2002 has 5. 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 had to have my engine replaced by vw and my car still isn't right. I bought my car in germany not the us. But it is registered with vwoa I feel like they sold me a defective product. They would not even consider listening to my complaints on the oil sludge problem. This cost me $7000.00 to replace my whole engine and time missed from work. (lost income) what can be done?
I went to turn on 2002 passat volkswagen a couple days ago and a flashing "stop" came on. I called my dealer after checking the manual and they said it sounded like a problem with the oil pick up tube and for me not to turn my car back on because it could ruin the engine. So I had my car towed to the dealer and they informed me that it is only under warranty if I can supply them with every receipt from owning the car. I have misplaced two so now they will not cover this and is costing me around $950.00 to get this fixed. I have always changed my oil on time. This seems to be there way of screwing there so called valued customers. I was on a web site (myvwlemon.com) and found numerous of passat owners with this exact problem and out come. Why is the consumer responsible for a poorly designed engine? The heat of the 1.8l turbo is breaking the oil down creating sludge. They obviously know of this problem because they issued a warranty extension. However, vw of america will only cover the warranty if the owner can provide every single receipt, something they know that very few people can do especially if some change their own oil…
The throttle body on my 2002 passat gls 1.8 turbo failed at only 56,000 miles. This part is not covered under the power train warranty. This seems to premature of a failure, and volkswagen should look into this. I have spoken to other volkswagen owners who own other passat models and they have had the same issues, some even at 30,000 miles. Vw take action please and investigate this issue. *nm

How far this goes
This page is kept out of search results because 5 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 5 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 2002 Volkswagen Passat?
Across 4 owner reports that included an odometer reading, half were filed by 45,000 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 2002 Volkswagen Passat?
5 reports have been filed with NHTSA, about 0.2 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.
