18613 General malfunction in the cooling system. To find the exact cause, you need to check all the components.
18617 Increased signal level coming out of the antifreeze temperature controller. This refers to the sensor installed at the output of the G83 engine cooling radiator.
37038 General error in the operation of the ECP system
53273 The code may occur in the form of malfunction 053273. For cars in 2014 and other years of production, an error indicates a lack of communication with the control module by the instrument cluster.
53285 This code may occur as error 053285. When it appears, the control unit is recommended to diagnose fault combinations in the J301 control module.
65535 General fault code of the control unit. The microprocessor module needs diagnostics, first of all you need to check its connector and wires.
VW Other malfunctions
P177D If this VAG error code is read using an ELM 327 adapter, it can be output as a combination of P 17 7D. The control unit (ECU) indicates a malfunction in the dual clutch gearbox.
P20EE Code P 20 EE indicates low efficiency in the operation of the catalytic system, the problem should be sought in the first bank
P30c000 (P30c0) Low fuel quality
U0103 Lack of communication with the gear shift control module. A possible cause may be poor contact or disconnection of the block from the transmission unit.
U0121 Loss of communication between the microprocessor-based motor control module and the ABS unit. It is necessary to check the integrity of all buses and connectors, to test the quality of the connection. A possible problem may be a malfunction of one of the units.
U0423 Malfunction of the control module of the instrument cluster, an incorrect signal is supplied from the device
U1017 On Passat B7 and other data models, the code indicates a loss of communication sequence for second-class devices. Exact equipment is not indicated, so you will have to check all the wires connected to the microprocessor.
U1025 Loss of communication sequence for second-class devices. In other words, the problem must be sought in electronics and wire damage.
U111100 (U1111) Literally, the code U1111 is translated as "limitation of work due to the lack of a message".
With such a malfunction, you need to perform the diagnosis:
- all connectors and connections connected to the control unit;
- circuit integrity;
- gateway module
- the main unit of the comfort system;
- steering column control module.
U111300 (U1113) Error U111300 stands for functionality limitation due to received message
U101F00 (U101F) Faulty brake control module. The causes of the problem can be many, ranging from poor contact of the sensors and ending with a lack of fluid in the expansion tank.
P130A00 (P130A) Arbitrary shutdown of engine cylinders. The manufacturer does not provide accurate information to resolve this problem, so the user will have to independently diagnose the power unit.
IN 02 Maintenance reminder for Passat B3 and other Volkswagen models
L01 The combination indicates a malfunction in the cruise control system, its activation is not possible. If everything works in a car, then check the functionality of the microprocessor module. To eliminate the cause on engines 2E and others, it is necessary to diagnose the operation of the switch on the steering wheel.
0522 General malfunction in the powertrain control module
4043 Short to positive terminal of pneumatic control valve of injectors N212
4500 Short circuit to a positive terminal or break in the wiring supplying the antifreeze temperature sensor
008E Code 008 appears as a result of a malfunction of the wheel damping adjustment valve installed in the front left to the
012 This code for cars 2003 and other years of release indicates problems in the operation of the malfunction indicator. The lamp is on, it is necessary to test the diode itself, as well as its wiring.
441 Lack of pressure in the fuel tank. The cause of the problem may be a malfunction of the adsorber.
462 On VW TD 2005 and other model years, this code indicates a malfunction in the throttle control module
513 Malfunction of the climatronics system. To clear the error, check the quality of the connections of all components.
