Our Permanent Solutions
Permanent DPF Solution
Blocked or failed DPF? We physically remove the substrate (required for code-out) and write a custom ECU file that bypasses DPF regen cycles. The fault clears, power returns, MPG restores — for life.
EGR Delete & Remap
Faulty EGR valve causing warning lights, rough idle, reduced MPG? We offer cleaning, repair, or full remap delete — whichever your vehicle needs. Permanent off-road solution.
AdBlue Fix — In 1 Hour
AdBlue no-start error? SCR system failure? We bypass the AdBlue system directly in the ECU. No more refills, no more dashboard warnings, no more expensive dealer quotes.

Frequently Asked Questions
Is a DPF / EGR / AdBlue delete legal in the UK?+
These solutions are sold for off-road / motorsport / export use only. Use on the public highway is at the customer's discretion and may be illegal.
Is it an MOT failure?+
Visual DPF presence is checked at MOT; we don't remove the casing where required. EGR/AdBlue code-outs are software.
Will my engine be louder afterwards?+
No noticeable change for standard exhausts.
How long does each solution take?+
Most jobs complete in 1–2 hours on your driveway.
Will the warning light come back?+
No — the fault is bypassed in the ECU. Lifetime warranty.
Can these be combined with a Stage 1 remap?+
Yes. We can bundle a custom Stage 1 file with any delete.
Do you cover commercial fleets?+
Yes — we look after several local fleets. Ask for fleet pricing.
