Failure analysis
Independent failure reports on turbos and injectors
Send us the failed unit and we find out why it failed. We strip and measure the turbocharger or injector, photograph what we find and put the root cause in writing, so a warranty provider, insurer or assessor can decide the claim on evidence rather than opinion.
- Strip-down inspection with photographs
- Root cause: part defect or vehicle fault
- Written report with a claim reference
- Failed unit kept for re-inspection
How it works
Our process
- 01
Book in
Tell us the claim reference and send the unit by courier, or we arrange collection.
- 02
Photograph and strip
The unit is photographed as received, then dismantled and every component examined.
- 03
Measure and test
Clearances and wear measured; injectors run on the test bench against the maker's test plan.
- 04
Report
Findings, probable cause, a clear determination and the actions needed before a replacement is fitted.
Why Turbo Speed
Done properly, backed by specialists
Independent
The determination comes from the bench, not from whoever sold or fitted the part.
Measured, not guessed
Clearances, wear and bench readings, with photographs of every finding.
Actionable
We list what must be fixed on the vehicle so the next unit does not fail the same way.
Who we work for
Warranty providers
Is the failure a defect in the part, or caused by the vehicle? A clear answer you can settle the claim on.
Insurers and loss assessors
Physical evidence, photographs and a written root cause for the claim file.
Fleets and breakdown networks
Find out why units keep failing on the same vehicles before you fit the next one.
Dealers and garages
An independent opinion when a customer disputes a turbo or injector fitted by you or by someone else.
What the report answers
The question behind every claim: did the part fail, or did something on the vehicle kill it? These are the causes we establish most often.
Turbochargers
- Oil starvation or delayed oil supply
- Contaminated oil, sludge or blocked oil feed
- Foreign object damage on the compressor or turbine side
- Overspeed from boost leaks or tuning
- Excessive exhaust temperature, restricted DPF or exhaust
- Oil ingress and engine runaway
- Manufacturing or material defect in the unit itself
Injectors
- Water or AdBlue in the fuel
- Debris from a failing high-pressure pump
- Normal wear against mileage
- Incorrect coding or fitting
- Nozzle, valve or armature defect

FAQ
Frequently asked questions
Is the assessment independent of any repair or sale?
Yes. The report states what failed and why, based on what we find on the bench. It is issued before, and separately from, any quote for a replacement or repair, and we have no stake in which way the claim is settled.
Can you assess a turbo or injector that you did not supply?
Yes. Most units we assess were supplied and fitted by someone else. We inspect them the same way as our own.
What happens to the part after the inspection?
The failed unit and all dismantled components are kept in our storage under the claim reference, so they stay available for a second inspection by you, the customer or another assessor. We return or dispose of them on your instruction.
Do you need the vehicle?
No. We work on the removed part. Vehicle history, mileage and the reported symptoms help us, so send what you have with the unit.
Can we set up an account?
Yes. Warranty providers, insurers and fleets can open a trade account with a claim reference on every report and invoicing per claim or per month.
