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
£1000-1200.

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
BOSCH, VDO, MAGNETTI MARELLI, SAGEM, SIEMENS & LUCAS ECU units and we are also
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
cost.

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.
