Send us your control unit — request first, package second
You're sending a valuable, often irreplaceable component. We treat it accordingly. Whether it's about preserving a special vehicle or keeping your workshop operational — your control unit is handled by senior engineers, with manufacturer-grade diagnostics and a binding fixed price before any work begins.
You keep the decision
Three points where you stay in control
After our assessment of your request
Whether you should remove and ship the control unit at all. If your description points toward a sensor, wiring harness, or connector issue, we tell you before you ship anything — the unit stays in the vehicle.
After the written quote with binding fixed price
Whether we do the work. Nothing begins without your approval. The only item without approval is the diagnostic flat fee — if the unit turns out to be not repairable or not defective at all, no further costs are incurred.
After the return
Where the remaining adaptation steps are performed on the vehicle — for example at a workshop with manufacturer diagnostics near you. Which steps those are is stated in the findings report beforehand.
How the submission works
Six steps from request to return
Submit your request
Enter vehicle, control unit type, and fault description in the form below. Don't ship anything yet. We respond with an assessment of whether shipping makes sense, plus instructions for removal and shipping. Photos of the type plate or fault help the diagnosis.
Package the control unit
First in an anti-static bag, then cushion it. Secure connector strips, cushion all sides in a sturdy box. No loose small parts, no accessories without prior agreement. Print the accompanying slip and include it loose — so sender, vehicle data, and fault description are in the box.
Ship it
Send the package insured and with tracking. The transport route is the only section we don't control ourselves. We confirm the shipping address after reviewing your request — so your unit never travels to the wrong destination.
Receipt confirmation
We confirm receipt by email. After the initial diagnosis, we tell you the planned timeframe.
Diagnosis & fixed price
After the analysis, you receive a written quote with a binding fixed price. Work begins only after your approval. Whether repairing the original or cloning to a tested replacement unit — the findings show the better path, the decision stays yours. The repaired original keeps stored software, coding, and immobilizer data.
Return
Before return shipping, we test the unit in a function test. Then the repaired or cloned control unit comes back insured and with tracking — including documentation of the work performed. Any remaining adaptation steps on the vehicle are clarified in advance.
Shipping address & instructions
Confirmed after your request is reviewed — so your unit never travels to the wrong destination.
Before you ship
Send the request form below first. We respond with an assessment and the confirmed shipping address. Don't send anything until you've heard from us.
When you ship
Insured, with tracking, and with the accompanying slip in the package. Photograph the unit before packaging and keep the drop-off receipt until the control unit is back with you.
Unsure about removal, packaging, or shipping? Describe your case briefly in the form below or contact our engineering team. You'll receive concrete guidance before you send the package.
Two aids for your package
Pack it right, document it well
Package anti-statically and shock-proof
First in an anti-static bag, then cushion all sides in a sturdy box. Secure connector strips so they can't bend or break in transit. No loose small parts, no accessories without prior agreement.
Accompanying slip
So sender, vehicle data, and fault description don't go missing in the box — print the accompanying slip and include it loose in the package. We provide the slip template with your shipping confirmation.
What you need for the request
Five mandatory fields, no removal, no shipping
Five mandatory fields
- • Your name
- • An email address — our response comes through it
- • Vehicle: make, model, engine, year — e.g. "Mercedes W212 E220 CDI 2011"
- • Control unit type from the dropdown — if nothing fits, choose "Other"
- • Fault description — three sentences are enough: What happened (e.g. limp mode, no-start, error message)? Since when? What was already checked or repaired?
Optional — speeds up the review
- • Phone number for follow-up questions
- • Part number from the unit's label and chassis number (VIN) — if at hand, just include them in the fault description
- • Already read-out fault codes, if available
The control unit does not need to be removed for the request. It stays in the vehicle until we've responded. Photos of the type plate or fault help the diagnosis — send them by email with reference to your request after you receive our response.
What happens after you submit
- • We respond with an assessment of whether shipping makes sense — or whether the cause is more likely in a sensor, wiring harness, or connector and the unit can stay in the vehicle.
- • You receive instructions for removal and shipping; for cloning, additionally the binding cost frame before you ship anything.
- • Only then do you send the package. The quote with fixed price follows after the inbound diagnosis — you decide whether we proceed.
Step 1
Submission request
You're not shipping anything yet. Your request is reviewed personally by our engineering team — you receive an assessment and shipping instructions. The written quote with binding fixed price follows after the inbound diagnosis; work begins only after your approval.
