When to bring us in
Extra capability.
Without extra theatre.
Use Engine Clean when a vehicle has moved beyond routine workshop time, when an evidence trail matters or when a fresh technical view protects the next decision.
Dealer or warranty fact-find
Record accessible condition, diagnostics and limitations in a form that the business and customer can follow.
Difficult diagnostic handover
Bring in specialist electrical, ECU, network or emissions testing while keeping the referring workshop informed.
Pre-sale or post-purchase concern
Establish present condition and priorities when a vehicle needs a clear route before sale, return or repair.
Built around workshop reality
We can start there.
Then move the job here.
One of the strongest advantages is flexibility: an initial inspection may happen at your premises or with the customer, then workshop time, collection or delivery can be arranged where the evidence shows it is required.
- 01Brief the job properly
Registration, mileage, reported fault, previous work, scan reports and the exact question you need answered.
- 02Initial inspection or diagnostic
We establish whether the next step can be completed mobile or needs workshop access and equipment.
- 03Workshop route where required
Collection, delivery or recovery can be considered where applicable and separately agreed.
- 04Evidence back to the trade
Findings, limitations and recommendations are returned through the communication route agreed at booking.
Work already documented
Three jobs where the evidence changed the next move.
MERCEDES CLA 220 d · P0401The EGR fault returned after replacement and a DPF clean.
Actuation testing narrowed the route instead of repeating the previous repair.
PEUGEOT 3008 · PRE / POST REPAIRWhat improved—and which additive-system evidence remained.Two scans were compared without treating the fault-count total as a diagnosis.
FORD TRANSIT · INDEPENDENT REPORTSeven findings and one dangerous roadworthiness concern.An MOT-qualified review strengthened the assessment without pretending it was an MOT.
Clear from the beginning
Useful boundaries
protect everybody.
Scope before attendanceThe question, available history, access and expected output are agreed first.
Testing before conclusionsFault descriptions and customer accounts guide the work; they do not replace it.
No hidden handoverDirect customer contact or further repair only happens through the agreed authority route.
Trade pricing by scopeRepeat and pre-filtered work can be agreed on a trade basis; travel, recovery and specialist testing remain job-specific.
Before the first job
Trade inspection
questions answered.
Will Engine Clean take over our customer?
No. The communication route is agreed at booking. We can report back to the referring business and communicate with the vehicle owner only where that has been authorised.
Can you inspect a vehicle at our premises?
Yes, where access and working conditions are suitable. Mobile attendance is useful for an initial fact-find; workshop equipment or extended testing may require the vehicle to come to us.
Do you offer collection and delivery?
Where applicable. Availability, distance, vehicle condition and recovery requirements are confirmed for each job.
Can you condemn a component from the fault-code description?
No. A code is evidence that a control unit detected a condition. Component testing, circuit checks, live data or further inspection may be needed before a repair route is justified.
How is trade work priced?
Pre-filtered and repeat work can be quoted on an agreed trade basis. Scope, travel, testing time, report depth and workshop requirements are confirmed before work starts.
Keep the customer. Keep control. Add the evidence.
