❓ DPF Service FAQ

Frequently Asked Questions
about DPF and diesel

All practical answers from our technician about DPF (diesel particulate filter), EGR valve, AdBlue, and vehicle inspection. Specific question? Call or WhatsApp.

+What is a DPF (Diesel Particulate Filter) and what does it do?

A DPF (Diesel Particulate Filter, also known as FAP in French) is a ceramic component in the exhaust line of a diesel. It captures soot particles produced during diesel combustion, drastically reducing fine particle emissions. Mandatory since Euro 5 (2009) on new diesels.

+Why does my DPF clog?

Four main causes: too many short urban trips (filter never reaches regeneration temperature of 550°C), lower-quality fuel, defective differential pressure sensor (false alarms), or normal aging (after 200,000+ km, unburnable ash accumulates).

+What's the average lifespan?

A well-maintained DPF (no defects) lasts 150,000 to 250,000 km. Urban use shortens this lifespan (60-80% of normal). Motorway use extends it (smooth automatic regeneration). When fully saturated with ash: replacement is inevitable.

+Cleaning or replacement — how to choose?

In 90% of cases, cleaning without removal is the right choice (€150-€300). Replacement is only unavoidable for: cracked or melted substrate, ash saturation >50g, physical damage. Our OBD diagnostic gives you an honest answer before any service.

+How much does DPF cleaning cost in Belgium?

Between €150 and €300 for standard brands (VW, Peugeot, Renault, Ford, Opel). €200-€400 for BMW. €200-€450 for Mercedes. Combo with EGR valve cleaning: €200-€400. Free quote before any service.

+What guarantee do you offer?

30-day guarantee on all DPF cleanings. If the light comes back on within that period, we return free of charge to diagnose the cause and re-treat. Valid throughout Belgium where we serve.

+Do you really come to my location?

Yes, throughout Wallonia, Brussels-Capital Region, and parts of Flanders (Antwerp, Limburg, Flemish Brabant, parts of East and West Flanders). For Flanders, service window is 60-120 min depending on location.

+Do you speak English?

Yes, fully fluent English-speaking service. Particularly comfortable for the international community in Brussels: NATO personnel, EU institutions staff, embassies, international schools (BSB, ISB), and expatriate professionals. Phone and WhatsApp support in English.

+What payment methods do you accept?

Cash, Bancontact (debit card), bank transfer. For businesses: 30-day invoice possible after agreement. No upfront payment — payment only after service completion and validation.

+Do you service vehicles other than cars?

Yes: vans (Sprinter, Crafter, Master, Transit), light trucks (Transit, Iveco Daily), older motorhomes and campers. Not for heavy trucks (>7.5 t) or buses — different specialized equipment required.
