Avoid unnecessary garage bills by identifying the real cause before replacing components. A proper diagnosis first, then the right fix for your vehicle.
DPFs commonly block due to frequent short journeys that do not allow regeneration to complete, an underlying engine or sensor fault, or internal damage. Before any work, I always check for underlying faults, since a clean will not fix a DPF that is blocking for a different reason.
For most road-going vehicles, an on-car chemical clean with forced regeneration clears the blockage without anything being removed. This is a software and on-car service only. I do not offer off-car machine cleaning or physical DPF removal. If your vehicle needs either, I will tell you during diagnostics and point you towards a specialist workshop.
Tell me your vehicle and what you're noticing, a warning light, smoke, or reduced power.
Home, work, or another suitable location across the wider East Midlands, with no ramp or lift needed. If your town isn't listed, send your postcode to check coverage.
Fault code analysis and an exhaust inspection to check for underlying issues.
Where suitable, I use an on-car chemical clean with forced regeneration. If the filter is damaged or too heavily ash-loaded, I will recommend specialist cleaning or replacement.
Starting points, final pricing is always confirmed against your exact vehicle before booking.
Not sure which option suits your vehicle? Message me on WhatsApp or get in touch.
For qualifying vehicles only, I can consider software-calibration requests involving DPF, EGR and AdBlue/SCR functions, including selected combinations with Stage 1. These options are not offered for vehicles used, or intended to be used, on public roads.
I will only consider a dedicated competition vehicle transported to and from events without using public roads, a vehicle being exported with supporting evidence, or a vehicle that will remain permanently outside public-road use. A vehicle being SORN, trailered occasionally or described as “off-road use only” does not by itself establish eligibility.
I will ask for the vehicle's intended use, ownership, storage or operating location and transport arrangements in writing. I may request supporting evidence and may refuse any enquiry where the intended use or legal position is unclear. A declaration does not override legal requirements or transfer away Myst Auto's responsibilities.
Prices are starting points for software work on a supported ECU and exclude physical hardware work. The £180 new-customer Stage 1 promotion does not apply to these controlled-use packages.
I'd rather tell you upfront than take your money for something that won't help.
For road-going vehicles, this is a diagnostic and on-car cleaning service. I do not offer off-car machine cleaning, physical DPF removal, or DPF deletion, bypass or monitoring deactivation.
Manufacturer-fitted emissions equipment that is missing, obviously modified or defective can result in an MOT major defect, and using a non-compliant vehicle on a public road may be unlawful. Separate controlled-use software enquiries may be considered only for verified competition, export or permanently non-road vehicles. A customer declaration does not override those requirements.
On-car cleaning is most effective for early-to-moderate blockages. Heavily ash-loaded or damaged DPFs may need machine cleaning or replacement, which I don't carry out myself but can refer to a specialist.
Send me your registration and I will advise whether on-car cleaning is suitable or whether the vehicle needs specialist repair or replacement.
