Dpf Specialist Avis 

Extremely proficient technician. Prompt , polite and courteous. Would highly recommend it from booking to completing the service.

From my first call to the company to the technician arriving was absolutely first class.
Luke was brilliant, explained everything fully, was polite and listened to what had happened to my van, he proceeded to do the diagnostic and then cleaned the filter, all the time telling me what he was doing. He gave good advice about maintaining the 'health' of my van too.
I can't recommend Luke and this company enough. Plus compared to the garage quoting £2,600 for a new filter....this was superb and I wouldn't hesitate to use the company again or recommend them to others.
First class, very happy customer.

Lewis was so helpful very honest and clear turnt up on time and explained everything would recommend 100% reliable and trustworthy thanks Lewis

The guy who came from Dpf specialist has fixed the dpf issue and his advice to prevent any issues in the future is really valuable ,overall experience was good

Amazing service friendly staff and sorted my problems great prices too
Will definitely return any other issues

The engineer was really friendly and explained everything to me. I can not be more pleased with how the whole process went.

Very quick service , chris arrived on tine & was very polite & very informative job well done would highly recommend

The technicians themselves are fine (have had one before) but the bookings/customer service side is beyond painful. The online calendar you ‘select’ a date from is only your ‘preferred’ date and they will then likely tell you they can’t do that day (happened both times with me, most people will assume that you are booking a slot and they clearly know this when they take your deposit payment).

Prepare to wait possibly days for a text response or to have to email them to get any response/confirmation of a booking. They then blamed me for not replying fast (24 hours for texts to get to them it seems) enough and said they couldn’t also change the oil & filter as a result (failed DPF regens often necessitate an oil change due to unspent fuel getting into the oil. I caved in and agreed to just the DPF clean.

Half an hour after the technician is meant to be here I call them, ‘he’s having problems with his van and we sent you a text’ (shockingly I didn’t get one). ‘Earliest we can now do is Saturday’, I’ve cancelled and asked for a refund, not holding out much hope of getting one. And fascinatingly the girl I just spoke to had the same name as the one who didn’t bother replying to me via text 4 days ago. So I’ve wasted 4 days including most of a day off work.

Update: got my deposit back quickly.

Craig was excellent. Honest in the possibility that cleaning wouldn't work. Polite and efficient too.

Turned up on time. My vehicle is complex , I am used to indrawn breathe followed by "I am not sure etc"- didn't phase him at all. He was obviously familiar with dealing with complex cars and had zero problem sorting it out. He was professional and friendly. Job completed rapidly and advice given afterwards. Based on the person who attended my house I recommend this company to anyone needing DPF sorting.

Adam was friendly and helpful and answered my questions. Efficient individual.

The engineer was spot-on, very knowledgeable friendly and would recommend,

Craig was excellent. He was on time and polite, and he completed the job professionally. He gave me some advice and recommendations which were also helpful.

Had them came out to clean dpf for it to only came back on after 4 days found out they didnt do what they say , chucked a bit of cleaner in , rev it few times when asked if regen was done he said yes they were here less than 30 mins . When light came back I actually had it force regen it as I had tool that took 40 mins on its own , so I they took my money and ran , should have read reviews first . Never again use them as I could have done what he done for 3 quarter of the price the asked

Very important warning to those with DPF issues!! Head for a Specialist garage rather. Stress free.
Chemicals were added to my car messing up house windows as well as my neighbour. Thankfully i had upvc cleaner.End result messed up my Car too!! Was told all O.K BUT a sensor will need replacing.
Same day DPF back,lost power?Got a quotation £800 inc labour and sensor!! I said No and manage to buy a £120 new sensor.
After repair it broke down onroute to work after system burst!!
Now my DPF specialist has found diagnostic misreading mistakes etc and is repairing my car.I offered hi the two extra chemical cans received by Mobile repair.He simply said dump them??
Now im stuck with outstanding payment for repair funds while this company has been paid in full for unprofessional service of my car. More shocking news but will keep for a later date.
Luckily for those receiving perfect service. BE CAREFULL ,DONT REGRET

Prompt , efficient , friendly service . Cleaned the filter perfectly and gave me hints and tips to ensure does not clog in the future .

Technician arrived earlier thab planned. Thry gave excellent advice about the cause of the loss of power in my vehicle. The DPF was done professionally and promptly. All done outside my home. Excellent service.

Great service and pleased with results

⚠️ WARNING: One of the worst companies I have ever had the misfortune to encounter
My car became sluggish, hesitant, and returned reduced MPG. After researching, the symptoms resembled a blocked DPF, but I made it clear from the start that I wasn’t sure it was a DPF issue. Auto Assist (trading as DPF Specialist) assured me they would carry out an in depth inspection and diagnostic first, and discuss the findings before doing any work.
Their brochure promises “state of the art equipment, highly trained engineers, industry leaders in DPF cleaning.” The reality was the complete opposite.
• They arrived 1 hour 15 minutes late • They began removing panels before doing any diagnostic • Their diagnostic showed faults unrelated to the DPF • They ignored those faults and carried out a DPF clean anyway
From the moment they took the first diagnostic to the moment they reassembled (poorly) the engine components and packed up, only 31 minutes had passed. The actual “clean” lasted under 15 minutes — far below the manufacturer’s stated process time for the equipment they use.
It then took two weeks, multiple calls, and emails before they reluctantly provided the diagnostic report they had promised. When it finally arrived, it was fabricated and misleading, clearly altered to justify the unnecessary DPF clean.
Unsurprisingly, the DPF clean made no difference to the car’s symptoms — because it was never a DPF issue. My credit card provider reviewed the evidence and refunded the full amount immediately.
Auto Assist (DPF Specialist) appear to perform the same rushed DPF clean on every vehicle, whether it needs it or not. When it doesn’t fix the problem, they simply claim your car “has other issues” and refuse responsibility.
⚠️ Additional Warning Auto Assist’s “DPF clean” involves dumping toxic waste directly onto your driveway instead of collecting it for proper disposal, as Environmental Health regulations require. The residue contains carcinogenic particulates and heavy metal contaminants that should never be released into the environment. This hazardous sludge is a serious danger to health and no responsible company would ever dispose of DPF waste this way.
A company that cuts corners on diagnostics, honesty, workmanship, and even hazardous waste disposal is not a company anyone should trust with their vehicle or their safety. Avoid them.
