Question: are vw tdi expensive to maintain?
Answer: A well-maintained diesel engine can easily go 400-500,000 miles. Assuming all other factors are the same (cost, repairs, etc), this car has already saved around $13,300 over 9 years or an average of $1488 per year in fuel costs alone (20,000 miles / 42 mpg = 476.2 * $3.44/gal = $1638/year).
