BMW Diagnostics Dublin — ISTA Fault Scan & Coding Checks
Dealer-level BMW diagnostics in Dublin using ISTA / Rheingold. A full fault scan across every control unit, a clear read on what the codes mean and a written summary you can act on.
In person across Dublin, Kildare, Wicklow & Meath · remote across Ireland
A warning light or a vague fault is rarely the whole story. We run a complete BMW diagnostic scan with ISTA / Rheingold — the same diagnostic platform used at dealer level — reading every control unit, not just the engine. You get the actual fault codes, a plain-English explanation of what they point to, and an honest view of what is worth doing next.
Diagnostics are useful before buying a used BMW, after a warning light appears, or to confirm a coding or retrofit job is clean. We work in person across Dublin and the surrounding counties, and the price is agreed before we start so there are no surprises.

Frequently asked questions
Can you diagnose BMW faults with ISTA?
Yes. We run a full fault scan with ISTA / Rheingold across every control unit, then explain the codes and give you a written summary of findings.
Do you do pre-purchase BMW inspections?
We offer a full diagnostic scan that is ideal before buying a used BMW — it shows stored faults and the overall health of the control units. It is a software scan, not a mechanical inspection.
Will you clear the fault codes?
We can read and clear codes, but clearing without fixing the cause only hides the issue. We explain what each code means so you can decide what to address.
What information do you need?
Your model, year, VIN-derived build and a short description of the symptoms or warning lights. That lets us prepare and confirm the price before we arrive.
What is possible depends on your exact model, year, head unit (NBT, NBT Evo or MGU) and software version, plus any installed hardware. We confirm compatibility from your model, year and VIN before any work starts.
