Who Is DTUK? And What Do We Do?

abysscalendarLarge-1.jpg picture by ABYSS69

DTUK®, or to give us our full name of Diesel Tuning UK LTD, was formed in 2005 by our Managing Director, Andrew Pawley. He saw a gap in the market for a no nonsense approach to diesel tuning and offer the UK consumers one of the best diesel tuning systems on the market without the premium price tag. This all came about after he purchased a 3.0V6 CDTI Vauxhall Vectra 177PS during 2004, after trying tuning boxes from other companies without any success, and seeing that most "manufacturers" claiming to make boxes in the UK were basically buying boxes from anywhere and passing them off as their own..

You will never hear us claim to make the hardware, the actual tuning boxes, which are manufactured and supplied by one of Germany’s longest established Diesel Tuning Box manufacturers, who we work closely with and have been doing so for over 8 years. We have been heavily involved in the development of various systems and the relevant software. In fact the majority of the software we use here at DTUK in unique to ourselves which has been developed, for the UK market, in house by Andrew himself.

A rare photo of the man himself..

In 2009 we moved into 1,000 sqft premises, which was a 1,000 times improvement from our humble beginnings. Recently we expanded our space into a second 1,000 sqft unit. We are open 5 days a week and weekends by appointment, so if you’re in the area then please pop in for a coffee or a chat, or both. We charge for neither.

We’re confident that DTUK® is the only company in today’s market place that offers 24 hour telephone and email support for all customers, in fact 9 times out of 10, when calling out of hours, you’ll probably speak to Andrew himself as he has a very hands on approach to the business. His ethos is that the customer comes first, as they’re our "bread and butter".

These have involved a variety of vehicles that we have purchased or leased for long-term testing, including a Seat Leon 2.0 TDI 170PS CR which uses the VAG Common Rail engine and uses the DTUK® CRD-T® system, a 3.0 VG Nissan Navara using the DTUK® PDI® system and an Audi RS3 which uses the latest DTUK® CRD-P® system for petrol engines.

Over projects that we have had over the last 8 years include 240bhp 1.9CDTI Vauxhall Astra Estate nick named "The Hearse",

following the hearse came our 202bhp 1.9CDTI Astra Van complete with full Astra VXR make over...

Check out for lots of info, plus feedback on our CR, CRD2 and CRD-T systems that are popular with Vauxhall Astra CDTI Owners.

The Astra Van was sold in 2008 and made way for a Nissan Navara that we used to develop softwate for the new DTUK® PDI system that connects to all 4 injectors. This was rolling roaded and produced a whopping 215bhp!!!!!

Check out for unbiased feedback from users of this owners forum, some of which are seeing upto a 14% improvement in fuel economy. The majority of diesel tuning box manufacturers/resellers continue to tune the Navara/Pathfinders via the common rail. We continue to use this method on the majority of cars/vans etc, apart from the majority of Japanese 4X4’s. If you read the Navara forums, you will read that several members have experienced problems with EML lights when using a common rail system, since we introduced the PDI system that connects to the 4 injectors, this problem has been eradicated... NO MORE LIGHTS, LESS PHONE CALLS AND EMAILS means less headaches for us ..

In 2009 we took delivery of a new Seat Leon 2.0TDI 170PS that uses VAG’s latest 2.0 Common Rail Engine that produces 170PS as standard, and an Alpine White BMW E91 335d with 286PS as standard and 580nm of torque.
