Send-in service
Car ECU Repair for Workshops: How Send-in Works
EMATS is built around car ECU repair for workshops. You keep the customer and the car; we take the module, find the fault at component level and repair it in Johor Bahru. Here is how the send-in service works from first message to return.

Five steps, from your bench to ours
- 01
WhatsApp first
Send the car model, the fault you see and the part number on the module label. A photo of the label helps.
- 02
Send or drop the module
Courier the module to us or drop it off in Johor Bahru.
- 03
Diagnosis before quote
We check the module on the bench and tell you the fault and the cost before any repair starts.
- 04
Repair and bench test
Once you agree, we repair at component level and test the module on the bench.
- 05
Return
The module goes back to your workshop, ready to refit in the car.
What to include with the module
- Car make, model and year
- The fault you saw and any fault codes
- Part number from the module label (a photo is fine)
- What has already been checked, such as wiring, power and earth
- Your workshop name and a contact for the return
Why repair rather than replace
A module that has failed often has one damaged part, joint or track, not a dead board. Repairing it keeps the original unit with the car.
Because diagnosis comes before the quote, you can show your customer the fault and the cost first, and decide together whether to repair.

Questions workshops ask
Do I need to call before sending a module?
Yes, please WhatsApp first with the fault and the part number so we can confirm what to send.
Can I drop the module off instead of sending it?
Yes. You can send it or drop it off in Johor Bahru. Message us first to arrange it.
Who removes and refits the module?
