What we do
Diesel diagnostics and work, explained in English
The diesel system has several components working in a chain — from the tank through the fuel filter, high-pressure pump, rail, injectors, and DPF. When one of them fails, the error often appears elsewhere in the chain, which is why diagnosing in order matters.
We come to your car — home, garage, office, or car park. We do the diagnosis on-site and, if the repair can be done without a lift, we do it there. Jobs that need a workshop — injector removal, pump replacement, DPF replacement — are handled with a pick-up and return scheme or with you bringing the car to us. Everything explained in English, before we touch anything.
If you’re outside the coverage area, message us with your location: we assess the distance before confirming.
How we work
Cheapest fix first, every time
The same symptom can come from a €30 part or a €2000 part. We always start at the bottom of the list and only move up if the diagnosis justifies it.
Chain diagnosis
OBD scan, pressure checks, injector return test, fuel filter inspection. This tells us where the problem actually is before we touch anything expensive.
What can be done without replacing parts
Forced DPF regeneration, injector cleaning without removal, parameter adjustments, fuel filter replacement. The cheapest bracket, and the one that solves more cases than people expect.
What requires removal and specialist work
If injectors or DPF need to be removed, we take them off and they go to specialist cleaning or replacement. The car stays with us or at the destination workshop while the work is done.
Major component replacement
High-pressure pump, new DPF, injector set. The most expensive bracket, and the last we reach — only when the diagnosis confirms there is no other way.
This is what sets us apart from many garages: we don’t start by replacing the most expensive part. We start by understanding what’s failing, and only then decide what to replace.
¿Tienes el FAP eliminado o estás pensando en quitarlo?
El truco está dejando de funcionar. Los contadores de partículas ya se usan en Bélgica, Países Bajos, Suiza y Alemania, y detectan un filtro retirado aunque el coche no dé error. Ven a una diagnosis del filtro antes de que sea tarde: a tiempo se resuelve con una regeneración desde 50 €.
Detailed information
Each component has its own page
If your issue is in a specific part of the system, go straight there. Pages are in Spanish, but we answer on WhatsApp in English.
DPF removal and the ITV
Why cutting the filter no longer works, and what to do if you’ve already done it. (page in Spanish)
DPF / particulate filter
Regeneration, chemical cleaning and replacement. Three levels by price. (page in Spanish)
Diesel injectors
Return test, cleaning without removal, removal and specialist service, coding. (page in Spanish)
High-pressure pump
Full chain diagnosis. Important warning about metal shavings contamination. (page in Spanish)
Low rail pressure
Real case: pressure code, and it wasn’t the pump. (page in Spanish)
Diesel glow plugs
Symptoms, testing and replacement. Especially relevant in winter. (page in Spanish)

FAQ
Frequently asked questions
What people ask us before the first visit.
Do you speak English?
Yes. Everything is explained in English — what we find, what needs doing, what it costs, and what the options are. If you don’t speak Spanish, you won’t be left guessing.
What do you do on the first visit?
A full diesel chain diagnosis: OBD scan of active codes, pressure checks, injector return test, and fuel filter inspection. From that we identify the real point of failure. Then we give you a fixed quote with options in price order — and you decide what to do.
Can you fix it at my location or does the car need to go to a workshop?
On-site work: full diagnosis, forced DPF regeneration, fuel filter replacement, injector return test, glow plug diagnosis, pump diagnosis. Requires removal or workshop: injector removal, DPF removal, high-pressure pump replacement. In those cases the car stays with us or the component is removed and sent to a specialist.
Why do you insist on the cheapest-first order?
Because many faults that look serious aren’t, and many faults that look minor are. A low rail pressure code, for example, is almost always attributed to the high-pressure pump — the most expensive part — but is sometimes a clogged fuel filter that’s fixed for €30. Starting cheap isn’t doing less: it’s diagnosing in logical order instead of replacing parts by assumption.
Can a DPF be cleaned or does it have to be replaced?
It can be cleaned in most cases if it’s addressed early. There are three levels depending on condition: forced regeneration (from €50), chemical cleaning (€200–400), and replacement with a refurbished or new filter (€400–2500). Cleaning restores the filter’s capacity only if the original cause of clogging is resolved — dirty injectors, EGR, oil consumption, constant urban use.
Do you work on cars outside the usual area?
The usual area is Costa Blanca, Valencia, Alicante and Murcia. Outside that, message us on WhatsApp with your exact location — we assess the distance before confirming. No charge for the assessment, only if we go ahead.
