Welcome to ECU Decode

Our site is under construction, if you can't find what your looking for contact us.

Our aim is to make the search function a quick powerful tool which will guide you towards the part you have.
First try the part number, if this does not identify the component try searching by make or version type, for example mems3, Siemens, Bosch etc.

I have almost 30 years experience in the automotive repair and diagnostic business and seen huge changes. Old ECU types could be tested to a degree in the past but later modules (unless common faults) cannot be tested accurately. We often see cases where customers have paid a fee to have a unit tested as GOOD to then waste more time and money to find the unit was faulty from the start, our service is not about glossy paint or the use of loose words like remanufactured!

We do not test units we receive unless stated otherwise. We prepare new and used parts to a state of reuse.
We require the part you want to use, and the original in some cases.
From this you will receive your part ready for programming or in a state to plug and play.

We aim to return parts within 24 hours.
