ISTA diagnostics on a BMW at Bromspec Motorworks

No guessing, no wasted parts

A flashing warning light doesn't have to mean an expensive guessing game. We use full ISTA dealer-level diagnostic systems — the same tools the main dealer uses — to read your vehicle properly and find the real cause, rather than replacing parts and hoping.

That accuracy saves you money. You get a clear explanation of what's actually wrong, what it will take to fix, and a price before any work starts.

  • Full ISTA factory-level diagnostics
  • Accurate fault-finding, clearly explained
  • Coding, programming & module work
  • Retrofits and battery registration

Specialists in BMW & MINI

These cars are our speciality, so we know their common faults inside out — from timing chains and cooling systems to electrical gremlins and coding after a repair. All other makes are welcome too, and every job is backed by genuine or OE-quality parts and the option of interest-free finance.
