Our News

By the end of the year we will be able to remap new BMW & MINI F generation models through the diagnostic port ! No more ECU removal, no more board removals ! Quicker, safer and cheaper.

All VW Group 1.6 TDi engines can now be remapped through the diagnostic port (OBD) thanks to our new remapping tool purchase. This reduces the cost from £375 to £275.

Thanks to continued investment we now have the capability to remap the 2.2 TDCi Ford Transt Custom through the diagnostic port. No more ECU removal means the price has dropped from £375 to £295. Book yours in today !

Audi S5 Engine Carbon Clean

We are increasingly busy with the engine cleans and they are now the majority of our work, either combined with a remap or on their own. People are now adopting an 'engine carbon clean' as part of their annual maintenance. Not only is it restoring performance and economy, by cleaning up expensive components like turbos, EGR valves, CATs & DPFs it is ensuring they last a lot longer thereby saving hundreds and thousands in repair bills.

The latest statement by the VW Group is -

  • New vehicles with EU6 engines currently available not affected
  • All petrol models, as well as V6 TDI and V8 TDI models, unaffected
  • Technical solutions being developed and will be presented to responsible authorities before end of October

We are increasingly busy with engine cleans and remaps, but are concerned to see and hear of unscrupulous remappers using scare tactics to get work from owners of Volkswagen, Audi, SEAT & Skoda vehicles. Owners will not face fines or road tax increases if they do not get their vehicles remapped. Whatever happens VW and the government will resolve it and issue statements on any corrective action to be done by the VW Group.
