Volkswagen Tiguan error codes: descriptions and decoding
Content
The latest vehicle models are equipped with advanced electronics. The Volkswagen Tiguan embodies all modern requirements for electronic equipment and computer systems. Therefore, to identify all sorts of failures and malfunctions, professional intervention and - without fail - computer diagnostics will be required.
Computer diagnostics of the Volkswagen Tiguan car
Computer diagnostics is necessary for any modern car in order to read error codes and identify the current state of the main components. Volkswagen Tiguan diagnostics is able to quickly detect all malfunctions in the car design and eliminate them in a timely manner. Error codes are designed to notify the driver or service station specialists about the presence of a particular problem.
All error codes are displayed on the computer screen in real time. The most advanced tracking systems can even recode the parameters so that the driver can immediately see what is wrong with his car.
Volkswagen Tiguan computer diagnostics are usually carried out after fault codes appear on the instrument panel. Less often, diagnostics are needed when certain systems work incorrectly (without errors on the dashboard).
Today, the use of special devices and stands allows you to thoroughly check the performance of all electronic systems of the car and prevent the occurrence of breakdowns.
Dealership specialists recommend that Volkswagen Tiguan owners undergo a computer diagnostics procedure once a year.

What does the EPS signal turn on mean?
One of the most worrisome drivers of the Volkswagen Tiguan has to consider is the EPS signal. The term itself stands for Electronic Power Control, since the design of modern Tiguans uses electronic throttle valves.
EPS is an electronic engine power control that includes brakes. Accordingly, if the EPS icon suddenly lights up on the dashboard, this may indicate problems with the brake system, since the lamp of this icon directly transmits a “distress signal” from the brake pedal sensor.
What should I do if the EPS light comes on while driving? It is worth taking a closer look at the light bulb: its constant burning (without blinking) indicates that the breakdown is permanent (this is definitely not an error or a failure). However, if the engine is running normally, it makes sense to drive a little more and look at the behavior of the burning lamp. If the EPS signal does not go out, computer diagnostics are required.
If EPS appears only at idle, and immediately goes out when you gas, then you need to replace the throttle body. This procedure is recommended to be carried out by specialists.
What do the error icons mean?
In addition to the EPS signal, other error codes may occur in a Volkswagen Tiguan. If the driver knows at least the main ones, it will be easier for him to navigate the operation. If the EPS signal lights up, then, as a rule, computer diagnostics reveals two main types of errors - p227 and p10a4.
Error p227
If error p227 lights up on the computer stand, then this indicates a low signal level of the throttle position sensor. In itself, this value is not critical, since the operation of the car still retains all the conditions for safe driving and braking. However, the driver needs to carry out repairs in the near future, because the throttle position sensor must always be in working condition.
Error p10a4
Error p10a4 indicates a malfunction of the brake control valve working on the intake. This error refers to mechanical, so it is worth replacing the valve as soon as possible. Operating the Tiguan with error code p10a4 can lead to an accident.
Deciphering other major error codes
EPS, p227, p10a4 are not the only errors in the Volkswagen Tiguan, in fact, the total number of codes exceeds tens of thousands. Below are tables with the most serious error codes for a motorist, which can significantly affect the performance of the car.
Table: error codes in Volkswagen Tiguan sensors
| VAG error code | Fault description |
| 00048-00054 | Breakdown in the sensors for determining the temperature of the heat exchanger, evaporator or footwell in the rear or front of the Volkswagen. |
| 00092 | Breakdown of the device for measuring the temperature of the starter battery. |
| 00135-00141 | Malfunction of the acceleration device of the front or rear wheels. |
| 00190-00193 | Damage to the touch device for the exterior door handles of the Volkswagen. |
| 00218 | The on-board computer receives a signal from the air humidity sensor, a malfunction is possible. |
| 00256 | The coolant pressure and temperature sensor failed. |
| 00282 | Malfunction in the speed sensor. |
| 00300 | The engine oil temperature sensor has detected an elevated temperature, an oil change is required. |
| 00438-00441 | Failure of gasoline level sensors or devices for fixing the position of the float. |
| 00763-00764 | Breakdown of the gas pressure sensor. |
| 00769-00770 | The device for determining the temperature of antifreeze at the outlet of the motor does not work. |
| 00772-00773 | Failure of oil pressure measuring devices. |
| 00778 | Error 00778 is also common among owners of Golf and other Volkswagen cars. This code indicates a malfunction in the steering angle sensor. |
| 01132-01133 | Infrared sensors do not work. |
| 01135 | The car interior security device has failed. |
| 01152 | The gearshift speed control device does not work. |
| 01154 | The pressure control device in the clutch actuator does not function. |
| 01171, 01172 | Damage to the temperature measurement devices for the front and rear seats. |
| 01424, 01425 | A malfunction has been detected in the operation of the rate-of-turn sensor. |
| 01445-01448 | The sensors for adjusting the driver's seat are out of order. |
| 16400—16403 (p0016—p0019) | Error code p0016 is quite common in Volkswagen vehicles. If the combination p0016 appeared on the display, then the on-board computer recorded malfunctions in the operation of the camshaft or crankshaft sensors. Signal mismatch detected. When the code p0016 appears, the car should be taken to a service station. |
| 16455—16458 (p0071—p0074) | The computer detected malfunctions in the operation of the ambient temperature sensor: incorrect signal levels or damage to the electrical circuit. |
Thus, guided by the code tables, you can independently identify a malfunction in the operation of electronic devices on a Volkswagen Tiguan car. However, experts do not recommend doing this or that repair work with their own hands: the design and equipment of the latest versions of the Tiguan is quite difficult for an unprepared and inexperienced driver.
