Fuel system faults are some of the most misdiagnosed issues in European vehicles. A bad injector code doesn't always mean a bad injector — and replacing injectors without testing them first is expensive guesswork.
Troy tests fuel delivery pressure, injector balance rates, pump output, and rail pressure under load before any parts are recommended.
Common Symptoms
Our Process
- 01 Fuel rail pressure test under load
- 02 Injector balance rate analysis
- 03 High-pressure pump output test
- 04 Injector return rate measurement
- 05 Injector bench test if required
- 06 Precision component replacement
- 07 Injector coding and adaptation
What's Included
Frequently Asked Questions
How do you test injectors without removing them?
We use factory software to perform balance rate tests and contribution tests with the engine running.
Do you replace or clean injectors?
Diesel injectors are typically replaced. Petrol injectors can sometimes be cleaned and flow-tested.
Can you recode injectors after replacement?
Yes. All diesel injectors require IMA coding after installation — we perform this with factory software.
