If your petrol car has a GPF warning light, is in limp mode, or is due an MOT, you're probably ready to book a professional GPF clean — but you want to know exactly what to expect first. This page answers every question petrol car owners ask before booking, with no jargon and no upselling.

BOOKING & SERVICE QUESTIONS — GPF CLEANING & REPAIR:

How do I find a GPF cleaning service near me? Auto Guru operates a fully mobile GPF cleaning service across the UK — we come to your home, workplace, or driveway. There's no need to search for a local garage; simply book online or call us and we'll confirm availability in your area. No recovery truck, no waiting room, no inconvenience.

How quickly can I get my GPF cleaned? In most cases, Auto Guru can attend within 24–48 hours of booking. We prioritise vehicles in limp mode or with urgent MOT deadlines. Same-day appointments may be available depending on your location — call us directly for urgent bookings.

Do I need to take my petrol car to a garage to get the GPF cleaned? No. Auto Guru's mobile service means we bring all specialist equipment directly to you. There's no need to arrange recovery or take time off work — we carry out the full GPF diagnostic and clean on-site at your home or workplace.

What happens during a professional GPF clean with Auto Guru? Our technician will: connect to your vehicle's OBD port to read live data and fault codes; assess GPF soot and ash load using specialist diagnostic software; carry out a professional-grade pressure clean to remove accumulated particulate matter; verify the result with a post-clean diagnostic; and clear all related fault codes. A test drive is performed where possible to confirm the fix.

Will GPF cleaning fix my engine warning light? In the majority of cases, yes. If the warning light is caused by a blocked or partially blocked GPF, a professional clean will restore filter function and allow fault codes to be cleared permanently. If the light is caused by a secondary fault — such as a faulty lambda sensor, injector issue, or turbo problem — our diagnostic will identify this and advise on the appropriate next step.

How long does a GPF clean take? A typical GPF diagnostic and clean takes between 1.5 and 3 hours depending on the vehicle make, model, and severity of blockage. We'll give you an accurate time estimate when you book so you can plan your day accordingly.

Is GPF cleaning a permanent fix? A professional clean restores your GPF to near-original efficiency and is a long-term solution in the vast majority of cases. However, if the underlying cause of blockage — such as predominantly short journeys, injector faults, or incorrect engine oil — is not addressed, the filter may block again over time. Auto Guru will provide tailored preventative advice after every service.

My petrol car is in limp mode — can you still clean the GPF? Yes. Limp mode is one of the most common symptoms of a severely blocked GPF and does not prevent us from carrying out the service. This is one of the most frequent reasons customers contact us. We'll diagnose the root cause, carry out the appropriate clean, and restore normal engine operation — all at your location.

Can you clean a GPF on a hybrid petrol car? Yes, in most cases. Many modern petrol hybrids — including mild hybrids (MHEV) and full hybrids with petrol direct injection — are fitted with GPFs. Our technicians are experienced with hybrid exhaust systems. Please confirm your vehicle make, model, and year when booking so we can advise on suitability before we attend.

Will GPF cleaning help me pass my MOT? Yes. If your MOT failure or advisory is related to a blocked GPF, excessive particulate emissions, or an illuminated warning light, a professional GPF clean is the most effective and cost-efficient solution before a retest. We recommend booking at least one week before your MOT date to allow time for the clean and a short settling period.

What if my GPF is too damaged to clean? If our diagnostic reveals that the GPF is cracked, melted, or beyond the point where cleaning will restore function, we will advise you honestly and provide a replacement quotation. We will never charge for a clean that we don't believe will resolve the issue — transparency is central to how we operate.

Do you offer a GPF cleaning service for fleet vehicles or company cars? Yes. Auto Guru offers trade and fleet rates for businesses managing multiple petrol vehicles. We can schedule batch visits to minimise vehicle downtime and provide full documentation for fleet maintenance records. Contact us directly to discuss fleet pricing and scheduling.

Can I book a GPF clean if I'm not sure whether my car has a GPF? Absolutely. Book a mobile diagnostic and our technician will confirm GPF fitment, assess its condition, and advise on the appropriate service. There is no obligation to proceed with a clean if it is not required — you only pay for what your vehicle actually needs.

What areas does Auto Guru cover for GPF cleaning? We operate across the UK with coverage expanding regularly. Our core service areas include London, the South East, the Midlands, and surrounding regions. Enter your postcode when booking to confirm availability, or call us directly for an immediate answer.

Is there a guarantee on GPF cleaning? Yes. Auto Guru stands behind every service. If your GPF warning light returns within a short period following our clean and is attributable to the same blockage, we will investigate and rectify at no additional charge. Full terms are provided at the point of booking.

How much does a mobile GPF clean cost compared to a garage? Auto Guru's mobile service is competitively priced against traditional garage rates — and when you factor in the cost of recovery, time off work, and the convenience of a doorstep service, the value is clear. We provide transparent, fixed pricing with no hidden charges. Call or book online for a quote specific to your vehicle.

What petrol car brands does Auto Guru service for GPF cleaning? We service all major petrol brands fitted with GPFs, including Volkswagen, Audi, BMW, Mercedes-Benz, Ford, Vauxhall, Toyota, Hyundai, Kia, Seat, Skoda, Peugeot, Renault, Nissan, and many more. If your petrol car has a direct injection engine and meets Euro 6d standards, we can help.

Can a GPF clean be combined with other services? Yes. Many customers combine a GPF clean with an injector service, fuel system clean, or engine diagnostic — particularly where injector deposits are contributing to excess soot production. Auto Guru will advise on any additional services that would benefit your vehicle during the initial diagnostic, with no pressure to proceed.

What should I do to prepare for my Auto Guru GPF appointment? Simply ensure the vehicle is accessible at your chosen location and that you have the vehicle keys available. If possible, avoid driving the car immediately before the appointment so the exhaust system is not excessively hot. Our technician will handle everything else.
