Bernie is a genuinely nice guy and knows anything and everything about DPF’s, he has fixed my van 2-3 times now and I wouldn’t use anyone else for diagnostics or DPF problems since meeting him.

Thanks Bernie, originally I was quoted £2,500 for a new DPF from my dealership for a new one! But was advised to get in touch with Bernie as he would be able to help! I am chuffed to bits with the customer service we received and value for money! Came out straightaway and very informative! Thanks again!x

I can’t recommend Bernie enough. Not only is he excellent at engine and DPF cleaning, he also helps identify any problems that might cause problems in the future. He’s a really nice gentleman as well, he didn’t mind me sending numerous messages about my car and was always polite and prompt with his replies. Yesterday he went out of his way to fit me in on a busy Sunday afternoon when I was having problems with my car, thanks Bernie, much appreciated!!!

We had our BMW 320i and 335d 'Terracleaned' last week by Bernie, who performed an Induction + Engine clean on the 320i and an EGR/Turbo + Engine clean on the 335d. Bernie noticed a misfire with the 320i after the job was finished, and suggested replacing the spark plugs, which was a good call as the spark plugs in the car weren't the correct type. Since the Terraclean / Spark plug change the car is completely transformed, with a massive increase in MPG. Motorway MPG is up from 42 to 52 and street driving has gone up from 25 to 34. It picks up speed better and any niggles I had before are now gone. As for the 335d, I immediately noticed that Turbo spool up was quicker, so the power comes in sooner and stronger. As for the MPG, it was pretty good before, getting about 48mpg on the motorway and 28mpg around town, but now I am getting about 5mpg more. I'd strongly recommend getting your car Terracleaned if you've just purchased a new, higher miles vehicle where you're unsure how well it's been looked after in the past... I intend on getting my cars Terracleaned every 2 years in order to maintain the benefits I'm noticing.

Cannot recommend the Terraclean service enough. I saved over £1000 on a main dealer recommendation for new DPF by having a clean which will offer me at least another 20,000 miles before needing a replacement filter. Thanks again.

Highly reccomended, phoned Bernie today, 05-06-17, he arrived at agreed time and, with the minimum of fuss, quickly diagnosed the problem on my 2.0lt Mondeo tdci. Problem sorted very swiftly even though it was raining and he was working outside. Knowing the sort of labour costs garages charge, all I can say is that I was very pleasantly surprised when presented with the bill. Knowledgable, friendly service at a very fair price. Thankyou Bernie.

DPF removal and clean on my Ford Focus 1.6TDCIDue to my poor MPG (43 average) and the car going into limp mode i spoke to Bernie, he told me the DPF would be totally clogged with ash. He took the car away to carryout the DPF clean.When i got it back it was like driving a different car, since i have had it back my average MPG is now 63. Great service and highly recommended.Thanks.

Bernie came to my home and did a clean on my 2010 Seat Leon FR. The process was straightforward from a customer point of view.Additionally Bernie helped me with some fault diagnosis on my turbo whilst he was here; potentially saving me a large amount of money had I taken it into a garage. Highly recommend A1 Terraclean, customer service at its best and Bernie is a genuine guy with a good bit of crack about him.

I was given dodgy information from a garage charging me for regenerations which they didn't do and trying to charge me £1250 for a new DPF. A1 TerraClean came out, arrived early and had the faulty sensor replaced rapidly. 5* service and no messing about. Polite, friendly and genuine service I would strongly recommend and will be using again in the future if the need arises. Thank you

Well I had looked in some detail of the TERRACLEAN SERVICE so last week decided to get my local agent Bernie to cast his magic wand over my 2004 SPRINTER VAN with 250.000 miles on clock...even though the engine was mechanically sound it struggled to achieve 65mph on roads.WOOOOOOWWWW .... MY VAN IS NOW DRIVING MINT !! PULLS LIKE A TRAIN...I CANT BELIEVE THAT AFTER ONE HOUR HOOKED UP TO BERNIES EQUIPMENT THAT THE TRANSFORMATION IS JUST.... STUNNING !! HIGHLY RECOMMEND THIS SERVICE.

Got my focus 2.o tdci done on 94 k miles and must admit was always sceptical about it but glad i took the leap. Definately made an improvement on tickover, performance and overall sound note has changed also. Feels a lot better to drive. Even cleared the fault and regen codes. Would definately recommend it if your old plugger is up on the miles and feeling lumpy. Happy 🙂

Bernie’s DPF Problems and Terraclean Blog


DPF Problem Diagnostics & DPF Cleaning

Fri 19th Jan 2018

2012 Peugeot Partner Van with a blocked DPF and in Limp Mode

A Company in Consett with a van off the road with DPF problems contacted me through a recommendation from a garage familiar with my work.

The Company had been given a quote of £1400.00 to rectify the problem with a replacement. they didn’t want to invest this much money in a repair on a 5 year old van.

First of all, I carried out a pressure test which confirmed the filter was blocked and also scanned the following faults:

  • P1490 Particle Filter. Detected Overloaded
  • P242f Particle Filter. Detected Clogged
  • P1435 Multiplexed additive pump. Can network fault or Pump fault
  • P1434 Multiplexed additive pump. Can network fault or Pump fault

The soot buildup was too excessive to allow a forced Regeneration.

I used the Terraclean DPF Cleaning System to remove the soot then tested the exhaust pressure to confirm the filter was clear.

Afterwards I did a road test to confirm the filter was clear and able to regenerate as normal.

To deal with the Additive fault I had to carry out tests on the system and found a configuration problem.

Cost of Repair and Diagnostics and reconfiguration £280.00 a saving of £1120.00 and peace of mind that the problem has been rectified properly.


TerraClean Peugeot 207 1.6 Petrol – Stockton-On -Tees

Sat 27th Jan 2018

Before the Terraclean Engine service the customer commented the car is running fine, but on occasion, it would sometimes produce a small amount of white smoke when the engine had warmed up.

First we checked the oil and coolant levels and also scanned the engine management for fault codes, but revealed nothing.

During the Terraclean service we monitored the engine with live data with our diagnostics equipment, and observed an occasional random misfire on cylinder 2 which seemed relevant and can be caused by several things, after the service the misfire didn’t occur again, we advised it would be a good idea to renew the spark plugs and change the air filter.


2008 Mondeo 2.0 TDCI DPF Problems and Terraclean

A customer from Stockton-On Tees that had previously used our services booked with us again after we had correctly diagnosed and repaired a simple problem with a turbocharger on his Previous car.

The customers new car had just developed a fault and illuminated the engine management light, another garage had scanned the engine for faults and revealed a fault for the DPF P2002 – DPF Efficiency, this code doesn’t identify the actual problem it simply means the engine management saw data that it doesn’t expect to see so the cause can be one of many things, in this case it was a perished hose causing a lower than expected pressure reading.

I replaced the hose then the customer took advantage of a Terraclean service at the same time as this saved him the cost of my call out and diagnostics so made the repair very economical and he will now benefit from improved fuel economy.

A very big problem in the motor trade is misdiagnosis leading to wasted money and failed repairs.

Today we had an example where the customer wanted to book us to do a DPF clean, the problem is until we have done our diagnostics which involves more than merely reading fault codes.

Once I had read the fault codes which included an indication of a blocked DPF but further testing showed this wasn’t the case, there was also a fault for an exhaust temperature sensor so infact this was the fault that caused a failed regeneration causing the other faults, in this case a clean would have been a wasted expense which is why so many fail to cure the problem.

If you think the services of a professional is expensive wait until you see how much an amateur costs!

This is a story that is typical in my days work, the customer had taken his car to a garage to solve an issue with his DPF last year and was charged £400 for 5 hours Diagnostics by a garage that doesn’t understand how the system works, which ended up with the garage not finding the fault the customer was advised to put an additive in the tank to assist regeneration which is like taking a painkiller, it doesn’t fix the fault but only relieves the symptom temporarily.

It took me 10 mins to find and fix the problem (a faulty sensor) the DPF had only a partitial blockage so we took the car on a road test during which the Regeneration took place naturally demonstrating that the car is now fixed and able to operate normally, the owner had been driving in Limp home mode for so long he didn’t even realise it was in reduced performance mode.


Ford – Peugeot – Citroen – DPF Vaporizer Valve

We are very experienced in diagnosing and fixing the problems with cars and vans from:

Ford  Peugeot & Citroen

A common issue with these is failure of the Exhaust fuel Vaporizer causing Regeneration failure these are an expensive part and very difficult to access & remove.

We have extensive experience in diagnosing and repairing these we have invested in solutions that will save you on costly replacement, previously the solution was replacement of both the DPF and the Vaporizer which is very costly we can save you up 75% on the cost of replacement and put you back on the road much more quickly.

Common DPF Fault Codes:

P244B Diesel Particulate Filter Differential Pressure Too High

P246C Diesel Particulate Filter Restriction – Forced Limited Power

P24A4 Diesel Particulate Filter Restriction – Soot Accumulation Too High (Bank 1)

P2463 Diesel Particulate Filter – Soot Accumulation

P246B Vehicle Conditions Incorrect For Diesel Particulate Filter Regeneration

P244C Catalyst Temperature Too Low During Regeneration,Bank 1

these fault codes are a record of an a event they are not a full diagnosis, they do not state what caused the event or confirm the actual state of the DPF, which is why so many garages without the proper training and equipment misdiagnose dpf issues, and cost the customer dearly with repairs and replacements 90% of dpf cleans and replacement carried out were not actually required.

If your garage plugs a computer in to read the codes and tells you it needs a new DPF without further testing it is highly likely that they are wrong and you will be in for a large bill or a cleaning service that isn’t required also without resolving the problem and sometimes making it worse, a large percentage of our customers have been elsewhere first only to be met by failure.


When is a DPF Problem not a DPF Fault?

Mercedes Sprinter 14/11/2018

Today I was called to look at a 2012 Mercedes Sprinter that had no power, it had previously been to a garage with a dpf issue which the owner believed they had cleaned, but in fact it had been gutted and mapped out, the problem apart from being illegal now is the van still had no power, the garage had only diagnosed and targeted the symptom of the problem which was low boost due to a vacuum transducer going faulty and venting the vacuum that controlled the turbo wastegate which resulted in the wastegate not closing so not able to produce any boost pressure in the intake, this caused the engine to run very rich and caused regenerations to fail, so what should have been a cheap fix was actually an incorrect expensive non fix for the owner, but people still look for the cheapest quote to fix a vehicle and end up paying a lot more,

If you think a good Technician is expensive wait till you hire a bad Mechanic.
