Kalimex is the UK distributor of the JLM Lubricants’ range of products which they supply to thousands of stockists throughout the UK and direct to the DPF Doctors.
Darren and DPF Doctor Chay Blyth explain why its a no for forced regens.
Too many technicians promote themselves as DPF specialists when they have neither the skillset nor the diagnostic expertise to meet the standard required for a first-time fix. Yet there’s a massive financial gain for garages with genuine DPF Knowhow to capitalise on the increase in blocked/damaged DPFs due to the stop start short journey driving that’s been established in the last few years. They need to invest in their technical development,” says Darren.
Chay Blyth DPF Doctor agrees saying: “Out of every 10 DPF assessments I undertake 6-7 are damaged beyond repair. The main issue is a lack of understanding from the customer but also from other garages. There is widespread use of cheap additives with a high iron content being applied regularly (fire juice as it’s commonly referred to in the DPF Doctor network), incorrect cleaning techniques and mechanics simply hitting that forced regen button on the scan tool, hoping for the best. What they don’t realise is that too many forced regens – as few as 3 – will melt the DPF! Yet I see mechanics not even asking a customer if their car’s had a forced regen before and if products with a high iron content have been used. If so, in what quantity.”
“All too often I take a call from a desperate customer and upon asking the initial question: ‘Has your car been seen by another garage?’ I’m met with the standard reply of: ‘Yes. They initially told me to put some DPF cleaning stuff in the fuel tank from Halfords and to thrash it for twenty miles on the motorway. That didn’t work so the garage tried several forced Regens. And then I was advised to come to you.’
Unfortunately, by this stage, we’re almost always dealing with a damaged beyond repair DPF – across all makes of car.”
The DPF Doctors share how to keep a DPF in good condition.
“One of the most effective things you can do is to change the oil and include an engine oil flush as part of the process. Carbon and diesel will accumulate in the oil, particularly on vehicles that are struggling to complete DPF regen cycles, and this contamination will promote DPF blockages. Clean oil helps to protect the DPF. Modern diesel engines are designed to trap emissions contaminants within the engine and exhaust to prevent them entering the atmosphere. One of the major drawbacks is that oil vapour is recirculated via the air intake with the intention of burning this off via the combustion process. The problem is that the oil contaminates the air intake which in turn traps soot particles, slowly constricting the air flow and the performance of the engine. Using a professional air intake cleaning process, such as the JLM Diesel Intake Extreme Clean System, will maintain engine performance, reduce emissions, and protect the DPF.”
Darren has developed a unique training portal including a mix of live, online and interactive options:
“There are three sections to the portal. Every workshop signing up for Darren’s training has unrestricted access to this for 12 months.
‘Live Training’ broadcast in full HD from Darren’s HQ in Ashington. Delegates can ask questions and Darren will answer them live.
‘Training Reruns’ section where every training session is uploaded so it can be viewed 24/7. Members can catch up on training and keep up to date at their own convenience. There are over 90 2-hour training sessions.
Video Guides’ section – a searchable series with 100+ short training videos offering ‘just in time’ training. Ideal when a technician has a job in their workshop, and they need guidance.
Members can access the portal 24 hours a day, 365 days a year. They can also attend as many live training sessions as often as they like; no pressure to learn everything to perfection first time around.
