The 1.8-liter Volkswagen RP mono-injection engine was produced from 1986 to 1993 and was installed on the second Golf or Jetta similar to it, as well as the Passat B3 and Seat Toledo. There were modifications of the unit with two types of injection: Mono-Jetronic and Mono-Motronic.
The EA827 1.8l series includes: RP, AAM, ABS, ADZ, PF, ADR, ARG, AEB, ANB.

Disadvantages of the VW RP engine
- Most of the problems of this engine are associated with the vagaries of the mono injection system.
- The reason for the unstable operation of the motor is usually air leakage or sensor failures.
- In second place are failures in the ignition system, see the distributor or wires.
- Saving on oil service often results in the replacement of hydraulic lifters.
- After 200 thousand km, oil consumption often appears due to stuck piston rings.
