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.

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 🙂

Then Burnie came and sorted it all, so incredibly knowledgeable and genuine lovely guy!!! Would give 10 stars!! Saved me a fortune!! Now drives like a dream not a puff of smoke!! And so much better on fuel consumption!!!! My dad had his car done as well and he says it's driving like a new car, it has power he didn't know it had!!!! Also better on fuel consumption!!

The pug 206 1.4 hdi with 106000 had the full treatment and the results are fantastic feels like a new engine as been dropped in ran it dry and we are getting 750 miles on a tank of fuel mostly motorway.

EGR Valves are well known for getting clogged up with carbon often blocking or sticking!

Did you know that the Turbo also gets clogged the same way and impairs its operation?

In Variable Vanes Turbos (VNT) the carbon build up causes desired boost pressures not being met properly, causing poor air fuel ratios which increases the soot produced during combustion, so the problem accelerates itself.

Terraclean have produced a tool that can clean the full system including EGR, Connecting pipework, EGR Cooler and the Turbo restoring the proper function of all the components, it is advised to clean the full system because just cleaning the egr does not give a lasting result as the soot will build back up quickly.
