Car electronics repair in Riga. We find the cause.
Car electronics repair in Riga with modern computerised equipment. We trace the fault to its cause in the wiring, sensors and control units, so the problem doesn't come back.
In brief
Car electronics repair means finding and fixing faults in your car's electronic systems: wiring, sensors and control units. GT Garage does this at its car service in Riga, Teika, Krustabaznīcas iela 12C. Diagnostics cost from €40, the mechanic agrees the repair price with you before work starts, and there is a warranty on labour and parts.
Car electronics repair work
Electronics affect almost every function in your car, from engine management to seat heating. We work on these systems:
- Engine management and fault codes
- ABS, ESP and airbag systems
- Lighting and electric windows
- Climate control and seat heating
- Central locking, alarm, immobiliser
- Multimedia and navigation system
- Electric mirrors and door locks
- Parasitic drain and battery discharge
- Control unit programming

Car electronic systems we check
A fault can hide in any of these places. That's why our diagnostics look at the whole circuit, not just the fault code.
- 1
Engine control unit (ECU)
We read fault codes, check sensor data and program the unit if needed.
- 2
ABS, ESP and airbags
Never ignore a warning light for a safety system.
- 3
Wiring and connections
Corroded contacts and damaged wires often cause faults that come and go.
- 4
Battery and power consumption
We look for a parasitic drain if the battery goes flat even when the car is parked.
- 5
Comfort systems
Lighting, electric windows, climate control, central locking and multimedia.
When should you get your car electronics checked?
Electronic faults often start with small things. If you notice any of these signs, it's better to get them checked early.
Warning light on
A Check Engine, ABS, ESP, airbag or other fault light appears on the dashboard.
Key problems
The car won't unlock, the immobiliser won't let it start, or the alarm reacts with a delay.
Battery drains quickly
The car draws power even when parked, and after a while it won't start.
Engine runs irregularly
Electronic faults cause a loss of power, higher fuel consumption or uneven running.
Comfort systems not working
Lights, electric windows, climate control or multimedia work only intermittently.
After an accident or water in the cabin
If water has got into the cabin or the car has been in an accident, check the electronics before new faults appear.

Car electronics repair FAQ
Didn't find an answer? Call or message us and a mechanic will reply.
Why should car electronic faults be fixed early?
So you can drive safely and a small fault doesn't turn into bigger damage. Even a minor electronic defect can affect how the engine runs or the safety systems.
How often should car electronics be diagnosed?
There is no set interval: diagnostics is needed when a warning light comes on or a system works erratically. We also recommend it after an accident or if water has got into the cabin.
How much does car electronics repair cost?
Diagnostics cost from €40, and the mechanic agrees the repair price with you before work starts. It depends on the fault and the car, so after diagnostics the mechanic calls you and explains the findings.
What are the symptoms of car electronic faults?
The most common are warning lights on the dashboard, systems that work intermittently, problems with the central locking or immobiliser, and a battery that drains quickly.
Can you fix just the faulty part without replacing the whole system?
Often, yes. Diagnostics shows whether the culprit is a wire, a connection, a sensor or a control unit, and we repair or replace only what is actually faulty.
How long does car electronics repair take?
It depends on the fault. Some we find quickly, others need more careful tracing. After diagnostics the mechanic will tell you how long the car will stay in the workshop.
