Packages

Prices start where they start because the car decides the rest. Some ECUs are written through the diagnostic port; others have to come out and go on the bench, which is more work. Send us the registration and we will tell you which yours is before you commit.

My freelander had multiple fault warnings popping up and I wasn’t sure what they meant, so I needed a diagnostic scan and report to give my mechanic. Precision Autoworks was incredibly helpful and made the whole process easy. 10/10, highly recommend!!

My car entered a limp mode, restricting my speed to under 10 mph, I contacted Precision Autoworks UK for a mobile diagnosis. Their technician arrived promptly at my home and efficiently identified and resolved the issue. The entire process, from inspection to clearing the faults, took roughly 30 minutes. I was extremely pleased with the fast and effective service.

Thank you to Precision Autoworks UK who I went to for my 2023 VW Golf R tuning for Stage 1. Ishy was very professional and showed me the process step-by-step throughly. We did a live data log before and after which was sent away. We received a custom map, tweaked and tuned specifically for this car. We refined the tune to give it a little bit more aggressive pops and bangs and to increase the torque. The car is now an entirely different beast and I am very happy of how it turned out. 10/10 will recommend to everyone looking to get more gains and power from their cars. Shoutout to Ishy. Legend 😎

Great communication, resolved issues and remap has improved sluggish car, now pleasant to drive. Four stars due to not being able to suggest what to do or where to go in the area for 2.5hrs whilst work was completed. I recommend a walk to a cafe called the kitchen. Thanks

Common questions

Will a remap damage my engine?

It is capable of it, which is why the checks matter more than the map. We run diagnostics first and will not tune on top of a fault, every write runs on a 100-amp battery support unit so voltage cannot drop mid-write, and the calibration stays inside limits the engine was built to handle. If your car is not a sensible candidate we will say so.

Do I need to tell my insurer?

Yes. A remap is a modification and insurers treat it as one, whether it adds power or is written for economy. Declaring it may change what you pay; not declaring it can leave you without cover at the point you need it.

Which stage do I need?

If the car is standard, Stage 1. If it has a DSG, ZF or S-Tronic gearbox and you want the shift to match, Stage 1 Plus. If a downpipe, intake or intercooler is already fitted, Stage 2. If the goal is fuel rather than pace, economy tuning. Tell us the car and what you want from it and we will point you at the right one.

Can the car be put back to standard?

Yes, if you take the USB backup of your original file. That is your car exactly as it left the factory and it can go back on whenever you want — before selling it, or before a dealer visit.

Do you fit the hardware for Stage 2?

Not at the moment. Mechanical fitting is outsourced while there is no in-house mechanic, so we do the software and can point you at fitters we trust for the parts. Get the hardware fitted, then bring the car to us.

What about DPF, EGR and AdBlue deletes?

We offer them strictly for off-road, motorsport or export vehicles. For a car used on public roads, the answer is repair rather than delete, and a diagnostics check tells you what has actually failed before anyone spends money on parts.
