Seat 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

Seat Oil Flush & Filter

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

Seat Intake System

An unfortunate side effect of Seat DPF problems tends to be Seat 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 Seat intake system decarb options, you'll receive more information from your customer service advisor.

Seat Intake System

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

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

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

Seat EGR Valve

Seat 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.

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

Seat EGR Valve

Seat 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.

Seat Swirl Flap

Seat 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.

Seat 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.

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

Seat Mass Air Flow

The Seat 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.

Seat MAF faults need resolving.

From £55 (Diagnosis)

Seat Sensor Faults

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

Any Seat 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.

Seat Sensor faults need identifying.

From £55 (Diagnosis)

Seat 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.

Seat Injector cleaning is popular.

From £15 (Per Injecter Test)

Seat Turbo Actuator

The Seat turbo actuator (also known as Seat 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)

Seat Turbo Problems

The Seat 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 Seat 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)

Seat Carbon

All engines produce carbon as a side effect of the engine combustion process. Seat 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 Seat Additive Treatments, Seat Chemical Cleaning & Seat Walnut Blasting.
