Audi DPF Diagnosis

Told there's DPF fault?
Horrified by the quote?

Worry not, we are the solution you're looking for.
First we need to confirm the diagnosis (we've seen many wrong guesses!)
and decide on the best solution.

Emissions Control

Commonly known as the DPF (short for Diesel Particulate Filter), they are a rather expensive filter designed to collect diesel particulate (carbon and soot) from the exhaust emissions. Essentially a honeycomb design within a metal housing the filter captures the particulate and then treats it at very high temperatures. This is called a regeneration process and results in a short period of smoky emissions. If the regeneration fails or the filter becomes too blocked the system cannot work and warnings will start occurring.

Common Other Repairs

Audi Oil Flush & Filter

For best practice we would always recommend having an Audi oil flush and filter renewal with Audi DPF Repairs.

A DPF becoming blocked causes the system to continously attempt regeneration (up until the filter reaches maximum capacity for regen) which involves injecting additional diesel through the system.

This tends to contaminate the oil, hence the recommendation to flush the oil and renew the filter.

Audi Intake System

An unfortunate side effect of Audi DPF problems tends to be Audi intake system carbon buildup.

Basically the soot and carbon deposits from the diesel system coke up the intake pipes, manifolds, egr valves etc. The volume of soot and carbon is much increased once the DPF becomes blocked and inefficient.

We offer multiple Audi intake system decarb options, you'll receive more information from your customer service advisor.

Audi Intake System

One of the main causes we find for Audi DPF and Audi carbon problems is an undetected Audi intake system leak.

A small split in a pipe may not cause sufficient deviation from expected values for an Audi MAF fault code to trigger, however it will be having an effect on the carbon build up and subsequent DPF status.

We offer an Audi Smoke Pro Plus leak detector test which will highlight any intake system leaks.

Audi EGR Valve

Audi Exhaust Gas Recirculation basically recirculates a portion of exhaust gases back into the engine cylinders.

The valve is controlled by either a vacuum based or an electronic actuator valve which opens or closes to admit the exhaust under certain conditions. EGR Valve actuators stuck open or closed cause DPF issues.

Audi EGR Valve cleaning can help, alternatively a new part may be required.

From £125 (Ultrasonic Cleaning)

Audi EGR Valve

Audi EGR Valves can be unreliable and cause problems and as they are a quite expensive part it has become popular under certain circumstances to blank the valve and bypass it from the system.

Mechanical blanking off is required and an engine ECU map adjustment to maintain emission standards.

There are pros & cons to all modifications, request an info pack or ask about this.

Audi Swirl Flap

Audi Swirl Flaps are small butterly valves fitted to the intake manifold just before the cylinder head intake ports and operated with either a vacuum based or electronic servo mechanism.

Audi Carbon build up on the flaps cause them to stick in one position and strain the system. Flaps can break & get sucked though the engine causing catastrophic failure.

Audi Swirl Flap Bypass is therefore very popular as a precaution.

Audi Mass Air Flow

The Audi MAF sensor is used to measure the mass flow rate of air entering the engine.

The purpose of this is for the engine control unit to calculate the correct fuel mass. This means that if the mass air flow sensor or associated pipes have a fault, the engine will over or under fuel. This tends to increase carbon build up.

Audi MAF faults need resolving.

From £55 (Diagnosis)

Audi Sensor Faults

The multitude of Audi sensors on the intake and exhaust system are all linked to the whole system running correctly.

Any Audi sensor faults can trigger error codes & poor running. Even minor inefficiencies or variations can cause carbon build up or inoperation of the Audi DPF regeneration process. A sure way to get a blocked DPF.

Audi Sensor faults need identifying.

From £55 (Diagnosis)

Audi Injector Problems

The injectors obviously inject the fuel entering the engine.

If an injector develops a fault the engine will be over or under fuelling. Not only is this bad for the cylinders but it will also lead to increased carbonisation and soot build up. Audi injector bench testing tends to be the best way of confirming injector status.

Audi Injector cleaning is popular.

From £15 (Per Injecter Test)

Audi Turbo Actuator

The Audi turbo actuator (also known as Audi wastegate actuator) is responsible for controlling the boost output from the turbo by providing a pressure release valve diverting the gases away from the turbine wheel.

Pressure & heat are a recipe for wear & tear. The actuator spring will weaken & allow premature opening or the diagphram could fail.

An EML will likely illuminate, always get this checked!

From £55 (Diagnosis)

Audi Turbo Problems

The Audi turbocharger works hard and if a problem does develop it would be wise not to ignore it!

Turbochargers get carbonised just like the rest of the system and an Audi Turbo ChemClean will do wonders as a preventative maintenance routine. Keeping the turbine clean definitely increases longevity.

We offer Turbo ChemCleaning or in worse case scenarios replacement of the turbocharger.

From £65 (Turbo ChemClean)

Audi Carbon

All engines produce carbon as a side effect of the engine combustion process. Audi Carbon Buildup Causes All Sorts of Problems!

Unfortunately not all of the carbon gets emitted via the exhaust system (to be filtered by the DPF), with modern recircularisation systems carbon deposits build up in the intake system. Audi Decarbonisation prevents bigger issues.

We offer Audi Additive Treatments, Audi Chemical Cleaning & Audi Walnut Blasting.
