Audi A4 / S4 / RS4 DPF problems and cleaning

Yes, we clean the DPF on diesel A4s, including B8 models, at your home or workplace for £275 + VAT. The filter stays on the car and most cleans take 60 to 90 minutes.

What we can do on the A4

DPF cleaning for £275 + VAT

Hardened soot is broken down with a cleaning solution, then burnt off with a forced regeneration while the filter stays fitted.

Diagnostics for £100 + VAT

For a warning that keeps coming back, we read the codes and live data to find the cause.

DPF delete for £220 + VAT

The ECU stops monitoring the filter and stops regenerating it.

A4 versions we work on

DPF work applies to diesel A4s, including B8 saloons and Avants. If yours is a petrol S4 or RS4 with a particulate filter warning, we also offer petrol particulate filter cleaning.

Engines and ECUs vary across the range, so send the registration and we'll confirm the work before you book.

Frequently asked questions

Can you clean the DPF on my A4?

Usually, yes. Cracked filters and those full of ash can't be cleaned, and we'll tell you from the readings before any work starts.

How long does an A4 DPF clean take?

Most take between 60 and 90 minutes. If the filter is very full, the regeneration may need a bit longer.

What does an A4 DPF clean cost?

The clean is £275 + VAT. A delete costs £220 + VAT but is only for off-road and export cars, because a DPF delete on a road car is illegal, as our DPF removal guide explains.

Does the A4's DPF have to come off?

No. The filter is cleaned in place, which saves on labour and keeps the car usable.

Book your A4 DPF clean

Send the registration and where the car will be, and we'll arrange a visit. Other models are on our Audi DPF page, and the same car can be booked for A4 remapping or checked for A4 EGR problems.
