Click here to visit our new website >>

You can now view & place orders for all of our programming services - you can also search our database of thousands of ECUs, BCMs, Clusters etc for sale

 Based on Sprowston road Norwich we are experts in diagnosing and either repairing or programming & replacing clusters on all makes and model cars, we can 'clone' information from one cluster to a secondhand unit if you have a faulty cluster and wish to fit a donor unit to your car - even if your original cluster is completely dead! (Many modern cars have immobiliser information programmed to them and will not work if you plug them straight in). We also repair missing pixels on displays, commonly a problem on Audi and Peugeot units particularly. We can correct the mileage on most makes and model cars, useful if you have fitted a secondhand instrument cluster and the display is reading an incorrect mileage reading, or if your dash has had a voltage surge and sent the mileage reading haywire (Often 999999 miles can be displayed after a jump start) Peugeot / Citroen owners take note: If you fit a secondhand Body Control Unit (BSI) to you car - the mileage is stored in this unit and will overwrite the mileage on your cluster if it was from a higher mileage car! We can correct this and set your mileage to the original reading!
Instrument cluster replacement programming / cloning service
 Bench programming available for most makes & models of instrument clusters. Most instrument clusters on modern cars are programmed to the immobiliser and cannot simply be replaced with a secondhand unit. we can re-program seconhand clusters for re-use by transferring data files internally from the original unit - even from completely dead units! pictured below are 4 of the most common clusters we regularly re-program, simply bring or send us your faulty cluster with your secondhand unit and let us do the rest! Prices vary between makes so please call us for a quote and book your job today, the average price for this service is £75+ VAT & postage - After we have worked our magic you will simply have to plug your replacement cluster into your car and it will start and run with your original keys with no further programming necessary.

Legal disclaimer - We offer this service for legal purposes only - It is an offence under the Trade Descriptions Act 1968 to sell a vehicle showing a lower or higher mileage than the true mileage - unless the buyer is informed of the true reading.
If the vehicle mileage cannot be guaranteed you must display a disclaimer on the odometer the same size or larger than the odometer itself. We will not be held responsible for any illegal misuse of our service. We correct digital mileage when it has been corrupted for one or more of the following reasons:
1 - New or second hand instruments fitted to the vehicle.
2 - The vehicle has been converted from km/h to mp/h and has an incorrect odometer reading.
3 - The cluster reading has been corrupted (Voltage 'spikes' from jump starting, changing battery etc)
4 - An ECU kit has been fitted to a vehicle
