One of the most reliable diesel engines of its time rarely bothers its owners. The majority of problems are associated with malfunctions in the operation of the Bosch VE37 electronic fuel injection pump. The aluminum cylinder head is susceptible to overheating, which quickly damages the mating surfaces. Replacing the timing belt with rollers can be expensive, but a valve failure always causes compression loss. With high mileage, it may be necessary to replace the turbocharger, as well as the EGR valve and hydraulic lifters.
