- What the customer had
- The car was in limp mode with a DPF warning light on.
- What it actually was
- A failed DPF pressure sensor and a split turbo hose. Another company had changed the sensor before us but never reset the codes or cleaned the filter, so it was never actually fixed.
- What we did
- We changed the turbo hose, reset the sensor codes and brought the car out of limp mode, then completed the regeneration and put everything back to proper working order.

Why Hemel Hempstead Diesels Block Their DPFs
Hemel is a commuter town, so a lot of diesels here mix a short school-run-and-shops week with the odd motorway trip. The short weeks are the ones that block a filter, and by the time the light comes on a single motorway run will not clear it.
A proper forced clean clears what those short trips cannot, and we confirm the filter is back within range before we leave.

Hemel Hempstead DPF Cleaning FAQs
How fast can you reach me in Hemel Hempstead?
About 16 minutes from our Watford base, straight down the M1. We work by appointment, so you get a booked slot rather than a wait, and we can often come the same day or the next.
Do you cover the whole of Hemel Hempstead?
Yes. We cover Hemel Hempstead and the surrounding HP1 area (HP1, HP2, HP3). Send your postcode and we will confirm before you book.
Will a clean fix it, or do I need a new DPF?
In most cases a clean restores the filter. We diagnose first and tell you straight if it is genuinely beyond cleaning, rather than selling you a replacement you may not need.
