Over the past few years all BMW vehicles have had the old style
mechanical dashboards replaced with new digital ones. The main reasons for this are down to cost and reliability.
These days it is cheaper to build an electronic dashboard than the old mechanical style dash boards. Unfortunately
this new technology has it's own set of problems. Electrical pulses in the car's electrical system can cause the
data in the dashboards onboard eeprom / MCU to become corrupt.
This could happen for example
vehicles battery has become discharged and the car had to be jump started.
vehicle may have been in for repair / service and the battery had to be
dashboard may develop an electrical fault.
dashboard may have been damaged in an accident or through vandalism.
speedo may have failed and you were forced to replace it with a new or second-hand unit.
This in turn causes the wrong reading to be displayed on your mileometer and will make selling your car very difficult.
If the new reading is low then the purchaser may think you have clocked the speedo. If the reading is high then
the value will be lower. This is where we can help by re programming the onboard eeprom / MCU / Micro with the
correct data. The new data overwrites the old data and the change becomes undetectable. This means that you will
be able to realise the full market value for your car when sold.
We carry out digital mileage correction across the complete range
of BMW vehicles in house. Unlike other companies, we carry out all programming on the premises, facilitating same
day service. We utilise the very latest state of the art programming equipment so you can be assured your vehicle
is in safe hands. All of our work is carried out at our premises in an EPA (Electrostatic Protective Area) We do
offer a mobile service as this work should not be carried out on the side of the road, where dirt and static can have dramatic
affects on the ESD sensitive electronic components inside your dashboard. Failure to have this work carried out
under the correct conditions can result in the corruption of the data stored in the processor and or chips within
your dashboard / CAS unit. Should this happen, your vehicle will be immobilised resulting in the purchase of a
new unit. Unlike many other so called correction specialists we don't have to replace the chip inside your instrument
cluster. We have the abillity to re-program all of the chips used inside BMW instrument clusters. Including the
very latest D80D0W and D160D0W.
BMW vehicles up to 2005 have the mileage stored in upto 5 locations, these are the instrument cluster, the EWS
the LCM (light control module) and the ignition key and auto gearbox. Vehicles built from 2005 onwards have the ability
to store the mileage in any of the 120 + ECU's on the vehicle. Everytime a fault occurs it will be logged by it's
controlling ECU along with a fault code and the mileage value at the time of the fault. (see below for more info) As part
of our mileage correction service we carry out a deep memory scan which scans every onboard ECU. Any historic faults
will have the code and mileage cleared, any present faults will have the value reset to the present mileage.
|The image below is a screen shot taken from our genuine BMW DIS (diagnostic information
system) In this example you can see that there is a fault code stored in the DSC control module. (Synamic Stability
Control module) If you look in the Messages and results section you will see that the mileage when the fault last
occured is listed. If these fault codes are not deleted then anyone with a DIS system can find references to the
old mileage. After correction we make sure that all vehicles are scanned with our genuine BMW DIS to find and delete
all old fault codes.
