Volkswagen diesel engine repair in Helsinki

Volkswagen diesel engines are popular for their excellent torque, fuel efficiency and durability. Even in demanding conditions, a diesel engine serves long when properly maintained – over time, repair needs may still arise. Volkkarihuolto's VW expertise in Helsinki ensures that Volkswagen diesel engine repair is done correctly and your car remains reliable.

Typical Volkswagen diesel engine faults

Volkswagen TDI diesel engines are generally reliable, but over time typical faults can develop in them. The most common problems relate to engine boosting and fuel supply:

EGR valve and particulate filter

The exhaust gas recirculation valve (EGR) can become coked up and stuck, causing engine power to decrease and operation to become uneven. The diesel particulate filter (DPF) also clogs easily in city driving, causing power loss and fault light activation.

Fuel injectors

Worn or contaminated injectors disrupt fuel injection, causing the engine to run unevenly, jerk during acceleration and increase consumption.

Turbocharger

The turbocharger wears over time, and a faulty turbo causes power loss, whistling sound and excessive smoke during acceleration.

Timing belt/chain

The timing belt or chain must be replaced on time. If the belt breaks or the chain stretches too much and jumps, the result will be serious engine damage.

High-pressure fuel pump

The high-pressure fuel pump, when faulty, can cause starting difficulties, power loss or even engine stalling.

Diesel engine fault symptoms

It's important to recognize diesel engine faults in time. Typical symptoms that indicate you should bring your Volkswagen to our repair shop in Helsinki: If you notice these symptoms, book a diagnostic appointment – quick response can prevent more serious damage from occurring.

Black smoke from exhaust

Black smoke from the exhaust during acceleration is a sign of incomplete combustion (e.g., EGR problem).

Power loss

The car doesn't pull normally – accelerates sluggishly and stalls uphill. The cause may be, for example, a clogged DPF or turbo problem.

Jerking and uneven running

The engine jerks while driving or runs unevenly at idle, indicating, for example, EGR valve or fuel supply disruption.

Starting problems

The engine starts poorly, especially in cold weather. The cause may be glow plug failure or fuel supply disruption.

What does Volkswagen diesel engine repair include?

We always start with thorough fault diagnosis using Volkswagen's own testers. When the fault is located, we plan the necessary measures. Diesel engine repair can include, for example, the following procedures:

Cleaning

Cleaning of coked EGR valve and intake manifold as well as regeneration of clogged DPF filter.

Parts replacement

When necessary, we replace faulty components (e.g., injectors, turbo, glow plugs or timing belt/chain) with quality spare parts.

Diagnostics and adjustment

Engine control updates, fuel system fine-tuning and test drives after repair to restore normal engine power and operation.

Volkswagen has continuously developed its diesel engine technology: well-known TDI engines, BlueMotion technology and new diesel models equipped with mild hybrid are examples.
