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…….

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.

DPF Fault Code P2002 – Diesel Particulate Filter Efficiency Below Threshold

Thursday 14th March 2019

P2002 is just one example of one of the many DPF fault codes, the code is set by the engine management when it sees something unexpected, but it doesn’t offer any information as to what the actual cause was, at this point many garages will make assumptions based either on the fault code description, or information they find on forums, the problem with this is the fault code can be generated for many different reasons, this will invalidate the majority of the solutions offered on forums.

Today I was booked to fix this problem on a Kia Sportage it had been to an independent garage where it was fitted with a new sensor but this didn’t solve the issue so the garage refereed the car to the local Kia Main Dealer who did correctly diagnose the problem as blocked pipework but didn’t have a solution they could offer apart from replacing the DPF the dealer then recommended Terraclean as they knew we have a solution for this problem, I carried out my tests to confirm the fault and there was indeed a restriction in the pipe work which I cleaned and retested with flow test and driven test to confirm 100% fix.

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

Fri 19th Jan 2018

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 DPF, they didn’t want to invest this much money in a repair on a near end of service 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.

Engine Diagnostics

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.

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.
