AFTER-SALES VEHICLE DIAGNOSTIC HEALTH REPORT

STAGE 1 — £69.00
DEALER-LEVEL DIAGNOSTIC HEALTH REPORT

An After-Sales Vehicle Diagnostic Health Report is a written digital report produced using our professional dealer-level diagnostic equipment after carrying out a full electronic scan of your vehicle.

YOUR REPORT CAN INCLUDE:

✓ Complete vehicle system scan
✓ ECU and control-module health checks
✓ Stored, current and historic fault codes
✓ Diagnostic Trouble Codes (DTCs)
✓ Warning-light and system faults
✓ Identified problems requiring further investigation
✓ Recommended repairs and corrective work
✓ Evidence of the vehicle's electronic condition at the time of testing
✓ Supporting diagnostic information for after-sales or warranty claims

PROTECT YOURSELF WITH DOCUMENTED DIAGNOSTIC EVIDENCE

Don't rely only on somebody telling you:

“THERE'S NOTHING WRONG WITH THE CAR.”

Our diagnostic health report provides written electronic evidence showing what the vehicle's control modules are reporting.

This can help establish what requires further investigation or repair and provide useful supporting evidence when dealing with a car dealer, garage or warranty provider.

STAGE 2 — £130.00 ⭐ RECOMMENDED
ADVANCED ECU SOFTWARE & CALIBRATION CHECK
BETTER VALUE • DEEPER INVESTIGATION • FEWER UNEXPECTED SURPRISES

Stage 2 goes beyond a standard diagnostic scan.

We carry out additional technical checks to help determine whether the vehicle's ECU software appears to be factory/original or has previously been modified or remapped.

STAGE 2 CAN INCLUDE:

✓ ECU software and calibration identification
✓ Check for evidence of previous ECU remapping or tuning
✓ Check whether ECU software appears factory/original or modified
✓ Investigation of potentially suppressed or deactivated diagnostic functions
✓ Checks for detectable software modifications relating to DPF/FAP, EGR, AdBlue/SCR and NOx systems
✓ Investigation of fault-code/DTC suppression where technically detectable
✓ ECU identification and software/calibration information
✓ Comparison of ECU findings with the vehicle's reported condition
✓ Written findings to support discussions with a dealer, garage or warranty provider

FIND OUT WHAT'S REALLY IN YOUR ECU

A vehicle may have been remapped or modified before you bought it, and you may never have been told.

A normal diagnostic scan may not, by itself, establish the vehicle's complete ECU software history.

Stage 2 provides a deeper technical investigation into the ECU software and calibration to identify evidence of previous modifications where technically detectable.

KNOW MORE ABOUT THE VEHICLE BEFORE THE PROBLEM BECOMES YOUR PROBLEM.

Stage 2 is our recommended option for customers wanting a more comprehensive picture of their vehicle's electronic and ECU condition.

It may identify evidence of previous modifications that aren't apparent from a standard diagnostic scan, helping reduce the risk of unexpected problems and expensive surprises later.

KNOW YOUR CONSUMER RIGHTS
BOUGHT YOUR VEHICLE FROM A MOTOR TRADER WITHIN THE LAST 6 MONTHS?

Under the Consumer Rights Act 2015, vehicles supplied by a trader must meet legal standards including being of satisfactory quality, fit for purpose and as described.

For qualifying faults discovered within the first six months, it is generally presumed that the fault existed when the vehicle was supplied unless the trader can prove otherwise. Depending on the circumstances, remedies can include repair or replacement and potentially a price reduction or rejection of the vehicle.

DIAGNOSTIC EVIDENCE CAN MATTER

If a trader disputes a customer's claim, obtaining an expert opinion or other evidence may be useful.

Our diagnostic reports can provide documented electronic findings to help you understand the vehicle's condition and support discussions with the supplying dealer, garage or warranty provider.

DON'T JUST ACCEPT:
“THERE'S NOTHING WRONG WITH IT.”
GET IT CHECKED.
GET IT DOCUMENTED.
GET THE EVIDENCE.
