At Dudley Auto Service, we provide expert DPF cleaning and AdBlue services to keep your diesel vehicle performing at its best. Located in Luton, our workshop specializes in diagnosing, repairing, and maintaining diesel particulate filter (DPF) and AdBlue systems for customers across Bedfordshire.
Our track record speaks for itself: 100% success rate in our last 50 DPF cleaning services, backed by our exclusive “No Repair, No Pay” warranty.
Whether you drive for work, family, or business, keeping your DPF and AdBlue systems properly maintained prevents costly breakdowns and extends your vehicle’s lifespan. Our team of skilled technicians serves drivers from Luton, St Albans, Dunstable, and surrounding areas with reliable, professional automotive solutions.
Modern diesel vehicles are fitted with a Diesel Particulate Filter (DPF) to reduce harmful soot and emissions. Over time, the DPF can become blocked with carbon build-up, leading to engine problems, reduced fuel economy, and dashboard warning lights.
AdBlue, on the other hand, is a liquid solution used in Selective Catalytic Reduction (SCR) systems. It helps convert harmful nitrogen oxides into harmless nitrogen and water vapor. When the AdBlue system malfunctions or runs low, your car may lose performance or even fail to start.
That’s where Dudley Auto Service steps in, offering complete DPF and AdBlue services for drivers across Luton and surrounding areas.
Just two weeks ago, a BMW 118d owner contacted us about his 2016 vehicle experiencing loss of power and DPF warning lights. He’d already been to another garage who diagnosed the problem and told him he needed an exhaust back pressure sensor replacement and DPF cleaning.
The customer was frustrated – he drove on the motorway for at least an hour, five days a week, which should have prevented DPF clogging through natural regeneration. Something didn’t add up.
Our Diagnostic Approach: Instead of simply replacing the parts as requested, we applied our systematic diagnostic process. Using our professional diagnostic equipment, we checked live data from the exhaust back pressure sensor and DPF differential pressure sensors. Both sensors were actually working perfectly – their readings were simply outside normal range due to the blocked DPF.
The Real Problem: Our diagnostics revealed a jammed EGR actuator. Since the ECU requires correct EGR operation for DPF regeneration, the automatic cleaning cycles had stopped working entirely.
Our Solution: Fixed the jammed EGR actuator, professionally cleaned the DPF, and road tested with forced regeneration to confirm proper operation.
Result: The BMW now runs with full power, DPF regenerates normally, and the customer saved money by not replacing working sensors.
A Ford Transit 2020 owner came to us panicking about an “AdBlue Low – No Start in 10 Miles” warning message. He’d just filled the AdBlue tank, but the warning persisted and wouldn’t clear.
Our Investigation: While the AdBlue tank was full, our diagnostics revealed the system wasn’t detecting the fluid level correctly. We traced the problem to damaged wiring in the loom near the AdBlue tank – a common issue where road debris and moisture cause corrosion.
The Fix: Repaired the damaged wiring loom and reset the system.
Result: Warning cleared immediately, and the customer avoided expensive AdBlue tank or sensor replacement that other garages might have suggested.
A Jaguar owner was frustrated with persistent “Faulty SCR System” warnings and fault codes for low AdBlue quality and insufficient SCR catalyst efficiency. Two previous garages had suggested replacing the entire SCR catalyst system – a £2,000+ repair.
Our Diagnosis: Advanced diagnostics revealed the SCR catalyst was actually fine. The problem was a blocked AdBlue injector preventing proper AdBlue delivery into the exhaust system.
Technical Note: This is a common issue we see regularly in Volvo and Jaguar vehicles, less frequently in Audi and VAG Group cars, and rarely in Mercedes-Benz vehicles.
Our Solution: Cleaned and recalibrated the AdBlue injector system.
Result: All warnings cleared, SCR system functioning perfectly, and the customer saved over £1,500 compared to unnecessary catalyst replacement.
These cases perfectly demonstrate why proper automotive diagnostics matter – and why we achieve a 100% success rate in our DPF and AdBlue services.

Q: What’s the difference between DPF and AdBlue problems? A: DPF issues usually affect engine performance and power, while AdBlue problems typically trigger warning messages and can prevent the vehicle from starting. Both require different diagnostic approaches.
Q: Why do some vehicle brands have more AdBlue injector problems? A: Based on our experience, Volvo and Jaguar vehicles seem more prone to blocked AdBlue injectors, while Mercedes-Benz vehicles are generally more reliable. This relates to injector design and AdBlue system architecture.
Q: Can you fix AdBlue “No Start” warnings? A: Yes, we regularly fix these issues. Often it’s wiring problems rather than expensive component replacement, as demonstrated in our Ford Transit case study.
Q: What’s your “No Repair, No Pay” warranty? A: We’re so confident in our DPF cleaning success that if we can’t fix your DPF problem, you don’t pay for the service. This applies specifically to our DPF cleaning services.
