Professional DME (petrol) and DDE (diesel) ECU cloning for BMW and MINI — used ECU adaptation, ISN matching, plug-and-play replacement. Mobile across London & the South-East. Trade rates for body shops and indie BMW garages.
When a BMW DME (petrol ECU) or DDE (diesel ECU) fails, the dealer's default fix is "new ECU + programming" at £800-£2,500+. We clone a used ECU instead — same end result, fraction of the price, often same-day on the driveway or at your workshop.
E and F series petrol BMWs — MSD80, MSD81, MSV80, MSV90, MEVD17 series. We read your original DME, transfer the data (VIN, ISN, software, coding) to a used donor DME. Result: plug-and-play replacement, no dealer coding needed.
MSD80 · MSV80 · MEVD17BMW diesels from EDC15 onwards — EDC16, EDC17, MD1CP002. Same principle: clone original DDE data onto a used donor unit. Cost-effective alternative to a new DDE + dealer coding. Most jobs same-day.
EDC17 · MD1 · all DDEWhen the original DME/DDE can't be read (water damage, fire damage, internal fault), we extract the ISN from the CAS or FEM and match a used DME/DDE to your immobiliser. The car sees the new ECU as if it were original.
CAS · FEM · ISN extractUsed gearbox controllers (ZF 6HP, 8HP) need adapting to your immobiliser. We read EGS ISN, match it to your CAS or FEM, and verify gear changes before leaving. Saves £500+ vs dealer-supplied unit.
6HP · 8HP · ISN matchBody shops, accident repair centres, salvage rebuilders welcome. Used DME, DDE, CAS, FEM and key sets adapted to your vehicle. Trade rates for repeat work. 30-day invoice terms for established accounts.

Mobile or postalECU cloning is unforgiving — wrong steps can brick a £1,000+ used ECU. Every job follows a strict read-then-write procedure with verification at every stage.
First we read your existing DME/DDE (if functional) and the CAS or FEM immobiliser module. This gives us the ISN, VIN, vehicle coding and complete ECU map. If the original ECU is dead, we extract the ISN from the CAS/FEM directly.
Used donor ECU is read for hardware compatibility, then your original data is written over the top — VIN, ISN, coding, software level, injector codes (for diesels). The donor ECU effectively becomes a copy of your original.
Fitted to your car, verified by start and drive. No further dealer coding needed in most cases. Trade jobs receive written documentation showing the work performed and the donor ECU's provenance.
Mobile key programming covers most modern marques and immobiliser systems. These are the makes we programme keys for most often:
Don't see your make? Give us a call — Japanese, Korean, French and Italian marques are all on the list, just send the registration over and we'll confirm.
BMW dealers charge £800-£2,500+ for a new DME/DDE plus programming. A used ECU cloned by DashTech costs a fraction of that — same end result, often same-day, full warranty.
F30 320d with water-damaged DDE. BMW quoted £2,200 for a new unit programmed. DashTech sorted a used DDE with ISN matching for £380. Plug-and-play. Saved nearly two grand.
We run a BMW body shop — DashTech does all our ECU cloning. Fast turnaround, same-day in most cases. Saves us postal time and gets cars out the door faster. Trade rates make it commercially viable too.
E90 330d had the DDE fail. Donor on eBay £180, DashTech cloned it for £250. Total saving vs main dealer: £1,400. Car runs perfectly. Will use again.
