What Is An ECU?

Each car is installed with several ECU units. ECU stands for “Engine Control Unit”
although the say term is given to electronic control modules of other systems.
There is an ECU for your engine management, one for your dashboard/lights,
one for your gearbox, one for your air bags, ABS and so on.
The engine ECU’s are also known as ECM (Engine Control Module).

What Does The ECU Do?

An ECU (Air Bag ECU) also known as an ECM (Electronic control module) is responsible
for all the electronic signals passed back and forward to the vehicle. Without an ECU,
your air bags would not deploy in an accident.

What Is ECU Coding?

Recently, manufacturers have begun coding all ecu’s to the vehicles they are installed on,
this is an act to cut down on crime as many people realised how expensive these units can
be and began breaking into vehicles. An ECU from main dealer can typically cost around

We have been in the business since 1972 and are able to repair the ecu’s from all
types of vehicles.

What We Do

As fully qualified ECU repair specialists we are capable of carrying out a wide range of
ECU repairs following an initial ECU soak testing which will help to identify the cause
of the problem and pinpoint it exactly.

In many cases a simple flash reset could be all that is required to get your ECU back into
working order but if your electronic control unit needs to be exchanged or replaced then
we are able to offer some great deals on new ones from a range of manufacturers including
proud to announce that we’ve got some fantastic cash saving offers on the latest range of
brand new FORD and VAUXHALL ECU models.

ECU’s are rarely manufactured by the car manufacturers. In most cases the manufacturer of
your ecu unit will be one of the following:

ECU Testing

Checked your wiring loom and all seems fine?

Not sure wether or not it is the ecu playing up?

Request us to “test” your ecu unit, if there’s no fault found then we only charge the
standard test fee. If your unit is found to be faulty then we’ll give you the option of
having the unit repaired – in this case, we’d wave the test fee and charge only the repair

Worried the fault is intermittant and may not show up?

We test all units extensively up to 24-48 hours to be absolutely sure of the ECU units
condition before allowing it to leave the premises. A majority of the time we even find
faults the customer was unaware of. Our repair costs are fixed depending on the ecu
part numbers and so all faults are repaired within one price.

Non-Repairable Unit?

On a day-to-day basis, customers are being told by their local garages and main dealers
that their ecu is “non-repairable” and needs replacing. Replacing an ECU can cost in the
excess of £1000+ yet we are able to repair old units even if it means changing the
entire circuitry and save you £100’s.

Plus we even give all our customers a full 12 months (1 Year) warranty!

Repair Or Exchange?

We keep many ecu’s in stock ready to be exchanged. If we don’t have a unit for exchange
ready in stock then we can always repair your own unit. If in the unlikely even your unit
is non-repairable, then we can source a replacement unit for you where possible.

  1. I have an Alfa airbag ECU which clears all faults – leaving “intermittent / unknown Fault” on OBD (code 176)
    I purchased an identical 2nd replacement and that also cleared all faults to leave the same “ECU fault” – this time code 218
    Can you clear this problem – I’ve check ALL the cabling

  2. Hello Steve

    Thank you for your enquiry,

    Either the second unit you purchased as a replacement was also faulty or you definitely have a fault somewhere on the vehicle. We can clear the fault codes on our bench but the minute you plug it back in the fault will re-appear (if the fault is present on the vehicle).

    Kind Regards


  3. Hi guys I have a 2000 1800cc s40 volvo it is the face lift model so is actually 2001 cross over. I have a problem with my air bag control module part number 30613048a according to another module specialist the mother board is burnt out so they are unable to connect to it to retrieve information. When asked if they would require my vehicle identification number etc so they can install the correct information coded for my vehicle they said that it is possible to copy the info from my original Module. this sounds strange as they must then have to plug into my burnt out dead mother board to retrieve this info that they also reckon earlier that they are unable to do this. can you please shed some light on this? and also do you have this type of module for sale and at what price please.

  4. Hello Darrell

    Thanks for the enquiry,

    If the PCB is damaged and burnt out beyond repair then there is a chance the data is not retrievable. We have sent you an email with further information and pricing on available units.

    Kind Regards


  5. I wonder if you can help me.

    I have an SRS airbag light on dashboard – constant flashing.

    I took it into the Toyota dealership to check it as it has happened before and they were able to clear the error that time. However, this time they could not clear the fault. They say the airbag ECU is faulty . MOT is due soon so need to get sorted. Have seen you advert but have a few questions.

    If I remove the ECU and post it to you – Do you think it is possible for you to repair the ECU ?
    If it works and I plug the ECU back in will it automatically clear the error – or will I still have to take it Toyota dealer for them to clear the code?
    How long will repair take?


  6. Hello George

    Thank you for your enquiry,

    We may be able to repair this unit or offer an exchange but we will require the part numbers from your airbag ECU. If you can give us a call with the part numbers we can confirm availability and pricing for you. Repairs vary depending on the part number, some easier units are repaired within 48 hours and others can take 5-7 working days.

    Kind Regards

  8. Hi Nigel

    Thanks for the enquiry,

    We’re currently out of stock on that part number and would need to see the unit before we can guarantee any kind of repair. If you prefer a replacement, give us a call and leave your details with us (name, contact number, vehicle registration and part numbers) and we can search to find one for you and give you a call once we get one back in stock.
