A really good job done Bernie, meant to get in touch, Dave with the 3ltr diesel BMW said his return journey home was so much smoother and just had its mot. The emissions as stated by the tester were as good as if the car was new. Sue’s diesel mini did smoke for the first few miles as you said, but says the car accelerates better and is returning better mpg. My TT diesel is certainly quicker and I’m getting just under 60mpg on a run, better than previous. Great job. Have recommended you to a few close friends who may get in touch. Thanks again Bernie.

Had the pleasure of meeting Bernie from A1 Terraclean this morning as he came round to work his magic on my old girl…04 plate vectra she was running rough as a pig, but after Bernie did his stuff along with a quick EGR change cos mine was sticking all I can see is…….WOW, she’s like a different car, definitely money well spent and I will definately be recommending him to everyone I know…the service is second to none and Bernie certainly knows his stuff.
So if ya motor lagging a bit, smoking a bit too much or generally a bit sluggish give Bernie a message on here…I guarantee you won’t be disappointed

Cant recommend enough! Excellent service cracking bloke! Massive improvements
Just had my A4 2.0 TDI turbo veins cleaned, and all I can say is wow! Before it was constantly over boosting, going into limp mode, and driving very rough. Now its the best its ever drove drives like new! The pipes wire like new once the machine was taken off and id imagine the turbo will be like that too. Cant recommend enough thanks again.

Terraclean Review
Wow. Just had the Terraclean Treatment and Turbo Clean done on my 2005 VW Caravelle with 235000 miles on the clock. Took it for a test drive this afternoon and was blown away. It’s like driving a different vehicle. Gone has the limp mode, and this hidden power has come from somewhere. Throttle response I never knew it had and everything running so much smoother than before. Engine sounds a lot quieter too. Had to double check the on board computer twice as it was telling me I was getting an average of 43mpg. Not bad for a vehicle with the aerodynamics of a brick. I have no hesitation in recommending this treatment. I would go as far as to say go get it done and see the results yourself. Fantastic service all round. To say I am pleased is an under statement. Thanks…….

DPF Regeneration
DPF regeneration normally takes place automatically, but sometimes for various reasons this may fail to take place leading to the DPF blocking and illuminating a warning light on the dashboard.
- We are able to carry out forced regeneration’s with our advanced Diagnostics.
- There is always another reason for Regeneration failure we are able to carry out assessments to identify the causes.
- Severely blocked Diesel particulate filters are not able to regenerate we also carry equipment to clean them while not having to remove them from the vehicle.
- We operate a mobile service at a location to suit you.

2014 Nissan Juke Blocked Dpf in Darlington
Today’s first Job was to Diagnose a Dpf issue on a Nissan Juke, It had been to another garage for repair and they had tried to clean the Dpf with 3 bottles of Dpf cleaner supplied by a well known motor factors but failed to clear the blockage the customer was told the dpf will need to be removed to be cleaned as they couldn’t clear it with the product supplied to them, the customer decided to book with us instead as we specialize in this type of work.
We confirmed the dpf was in fact blocked and carried out a Terraclean Dpf clean which reduced the soot content enough that we were able to test and carry out a regeneration which was successful.
2014 Ford Transit DPF
I was booked to clean a blocked Transit DPF in Stockton-on-Tees because the customer was told the DPF was blocked by another garage & required cleaning.
Diagnosis
I always start with a fault code scan and I have to bear in mind some fault codes may not be present as they have often been deleted beforehand which isn’t a good idea if you don’t understand what has caused them.
I was presented with the following codes:
P2033 – Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
P246C – Particulate Filter Restriction – Forced Limited Power (Bank 1)
P2463 – Particulate Filter Restriction – Soot Accumulation (Bank 1)
I then view actual live data to establish the calculated soot level, and also measure the exhaust differential pressure so I can decide if the DPF does require cleaning, in this case it could be cleared with a regeneration, the temperature sensor fault is however preventing a regeneration taking place, many people would just replace the sensor (this would have wasted about £200), I went further to establish if the error is the sensor itself or the wiring that its connected to, I first verified the ecu wasn’t receiving any data from the sensor by monitoring live data on the computer with the engine running and compare the temperature of the other 2 sensors and confirmed it wasn’t seeing any data, and to test the wiring I used a sensor simulator which confirmed it still didn’t see any data, I then tested the wiring further down the harness and found continuity to the ecu, so the fault had to be in the harness plug there was no visual sign of a break so I gently pulled on the wires in the back of the plug the signal wire broke free as it was only the insulation that was intact the copper wire inside had broken, I carried out a repair on the wire and retested to confirm the fix.
The moral of this story is that you need to understand the system to be able to correctly assess the problem, before you can fix it, in this case a clean wasn’t required despite another garage saying it did and it wouldn’t have solved the issue.
Nissan Juke Blocked Dpf
This car had been to other garages before me and had £600 spent on it and no further forward, in fact the car was losing more power every day.
My Diagnosis
Initially I scanned for faults and found a fault for differential pressure sensor which is what monitors the dpf pressure and calculates the soot content. so I checked the pressure and found it to be 960 mbar at idle which is severely blocked, I preceded with a Terraclean Dpf clean and afterwards the back pressure was 60 mbar at idle my eventual target is below 10 mbar, my next step was to establish the reason the dpf became blocked, I then identified poor boost performance from the turbo which one garage had told the owner it needed replacing, so I set about with further tests to confirm this but I identified a blocked vacuum pipe which was stopping the turbo being activated.
The Repair to original cause
I cleared the vacuum blockage and normal service resumed, I then drove the car and the car did a successful regeneration with no further issues. If I had been contacted when the problem first started this would have been a very inexpensive repair
Blocked DPF 2011 Skoda Octavia – Middlesbrough
Saturday 16/03/2019
Faults Stored on Engine Control Unit:
P0237 – Boost Pressure Sensor Signal Too Low
P2463 – Diesel Particulate Filter Partially Clogged
I was booked to clean the dpf on this vehicle, I always carry out my own Diagnostics which involves more than just reading the fault codes these are only meant to give you a starting point where to start looking for a problem.
The DPF is always the victim so it is important to find the cause first as cleaning alone doesn’t solve the problem, in this case the owner bought the car with the boost issue but no dpf issue at the time, the garage that sold him the car said they would fix the problem and they replaced the Map sensor & turbo vacuum transducer (N75 Valve) which didn’t solve the problem the owner continued to use the car unaware that the DPF can not regenerate with this issue which led to the DPF becoming blocked, the garage wrongly informed the owner that the dpf issue needs to be fixed before they can fix the boost issue that they had so far failed to fix.
My diagnosis involved testing the Map sensor circuit as the ecu wasn’t being provided with the manifold pressure signal so the car was driving in super limp mode, in my tests I established there was no 5v reference voltage going to the sensor so I tested this by providing a 5v feed to the sensor which confirmed the sensor was ok, I then Cleaned the dpf as it was to blocked now to carry out a Forged regeneration, I then carried out a forced regeneration with my Professional diagnostics equipment the car is now fixed and fault free.
The owner had taken the car to several so called specialists with diagnostic tools well capable of doing the work but what they lacked was expertise to use the equipment to find and fix the real problems.
Kia Sportage – P2002 – Diesel Particulate Filter Efficiency Below Threshold

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
Sat 27th Jan 2018
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.

2011 Nissan Qashqai DPF Light & Engine Management Light
25 Feb 2018
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.
2009 Audi A3 DPF Problem with Flashing Glow Light and EML in Darlington
If you think the services of a professional is expensive wait until you see how much an amateur costs!
March 23rd, 2018
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 Vaporiser 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.

DPF removal and clean on my Ford Focus 1.6TDCI
Due 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.

Seeing posts on fb about terraclean i thought id give it a go. I always keep my cars fully serviced i didnt think it would make much of a difference but couldnt do no harm to keep it tip top my BMW X5 3.0d Bernie arrived as agreed on sunday afternoo . And got straight on with it cleared a couple fault codes and set away doing his thing. I drove to work this morning and it feels like hes put in a brand new engine in my car loads of torqe and power and 100 times more responsive.. how wrong was i. Bernie thank you massive difference and such a nice bloke would reccommend him to anyone.
