Terraclean Review – Phil Rolfe – Audi TT, Mini, BMW 530D – Bishop Auckland

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

Ben Carroll – Wallsend – Audi A4 TerraClean Review

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.

Darren Michael Lloyd – Toft Hill Bishop Auckland – VW T5 TerraClean Review

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…….

Terraclean is a Decarbonisation process administered via your fuel system this enables the clean to reach more places including the injection system.

It restores injector atomisation and remove’s tars and lacquers that build up inside which improves injector response times and fuel vaporisation for a cleaner more complete burn during combustion.

  • Restores Lost Economy
  • Restores Lost Performance
  • Reduces Emissions

Prices: Up to 2 litre £110 / Larger than 2 Litre £130



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.


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.
