Your engine breathes better professional decarbonization from 120€ + VAT
Professional cleaning with pure hydrogen + additives for valves, EGR, turbo, DPF and injectors. Annual maintenance recommended. If the intake is heavily carbonized, also we dismantle and clean by ultrasound.
Carbon in your engine it doesn't go away on its own and multiplies breakdowns every month
When the engine starts with loss of power, smoke, high consumption, unstable idle or engine light on, every week without action adds carbon buildup to valves, EGR, turbo, and particulate filter. What today are 120 ? + VAT of preventive decarbonisation, in 4-6 weeks it easily turns into 1,500 - 3,500 ? in consecutive breakdowns (Saturated DPF, broken EGR, damaged turbo, injectors).

unique in Mallorca with professional ultrasound + hydrogen decarbonization
We combine the two most effective technologies on the market to return your engine to factory condition: hydrogen decarbonisation as annual maintenance + ultrasound cleaning when parts need to be disassembled.

When disassembly is required, parts come out like new
We have ultrasonic cleaning machine specific for engine parts. When the case is severe (cemented intake, clogged EGR, blocked EGR cooler), we physically dismantle the parts and place them in the ultrasonic tank with professional chemicals.
Result: the parts return to factory condition without replacing anything. You save the cost of a new EGR (400 - 800 ?), a new EGR cooler (350 - 700 ?) or a new intake manifold (450 - 900 ?). Multiply this by the labor cost and you'll understand the advantage.
In Mallorca, we are one of the few workshops with this combination of technologies available to the end customer.

OBD errors that are solved with decarbonization
Codes that frequently disappear after a professional decarbonization (alone or with disassembly depending on severity).
Low turbo boost
- Meaning
- Turbo not generating nominal pressure. Common cause: carbonized fins, variable geometry blocked by soot.
- Solution
- Decarbonisation + reset. If the turbo is completely caked, disassembly + ultrasound.
Insufficient EGR flow
- Meaning
- EGR valve stuck by carbon. Restricted mechanical opening.
- Solution
- Intermediate decarbonization dissolves carbon. In severe cases, EGR removal + ultrasound.
Excessive EGR flow
- Meaning
- EGR not closing correctly due to dirt. Permanent rich mixture.
- Solution
- Deep EGR cleaning. Restores correct closing function.
DPF high soot accumulation
- Meaning
- DPF saturation. Carbon build-up from poor combustion + carbonized intake.
- Solution
- Decarbonization improves combustion + DPF cleaning if saturation > 60%.
Low efficiency catalytic converter
- Meaning
- DOC/catalyst does not oxidize hydrocarbons correctly. Carbon buildup.
- Solution
- Additive decarbonization + check lambda sensors.
Air mass flow correlation
- Meaning
- MAF sensor reads out of range due to dirt or carbonized intake.
- Solution
- MAF cleaning + intake decarbonization. If the intake is cemented, disassembly required.
Economic comparison decarbonization vs future breakdowns
The cost of annual maintenance decarbonization vs. the cost of not doing it and repairing the breakdowns that follow.
| Option | Approximate cost + VAT | Comment |
|---|---|---|
| Preventive decarbonization 1 h | 120 € | Normal passenger cars 1 time a year or every 80,000 - 100,000 km factory result. |
| Intermediate decarbonization 1.5 h | 140 € | SUV or > 100,000 km extra cleaning EGR + turbo + intake. |
| Intensive decarbonization 2 h | 180 € | Double cycle + gas test for heavily carbonized engines with symptoms. |
| Disassembly + ultrasound (commercial vehicles) | from 580 ? | Intake + EGR + EGR cooler. Severe case. Save on new parts. |
| Disassembly + ultrasound (high-end) | from 980 ? | Audi BMW Mercedes Land Rover Porsche. Serious case. |
| Professional DPF Cleaning | from 280 ? | If you waited too long and the filter became saturated (see DPF). |
| New OEM EGR | 400 - 800EUR | If it wasn't cleaned in time and the valve broke. |
| New / reconditioned turbo | 800 - 2.500 ? | If carbon buildup blocked variable geometry and caused the turbo to fail. |
| New DPF OEM + labor | 1,500 - 3,500 EUR | If the filter crystallized due to chronic malfunction. |
Summary: do annual maintenance decarbonization (120 - 180 ?) and you'll very likely avoid breakdowns that cost between 10 and 30 times more. It's pure mathematics.

If you're looking for engine decarbonization Palma, EGR intake cleaning Inca, engine ultrasound Marratxí o hydrogen engine Calvià we are the local benchmark.
Technical specialists in professional engine cleaning
What do we do? Full engine hydrogen decarbonization (intake, valves, turbo, EGR, DPF, combustion chambers, injectors) + physical ultrasonic cleaning when parts need to be disassembled.
How do we work? We always start with OEM diagnosis to identify the engine's real condition. If symptoms are mild or it's maintenance, hydrogen decarbonization is enough. If the intake or EGR are heavily carbonized, we propose physical removal + ultrasound to restore original parts without replacing them.
Why do decarbonisation as annual maintenance? Because it prevents DPF saturation, EGR valve deterioration, turbo carbonization, and valve deposits. An annual decarbonisation at 120 - 180EUR avoids breakdowns of 1,500 - 3,500EUR that would appear in 1-3 years if not done.

Engine internal cleaning process by introducing pure hydrogen in the intake for 1-2 hours. Dissolves and removes carbon deposits from valves, EGR, turbo, DPF, and combustion chambers.
At Zamule Cars Palma: 120 ? + VAT (1h basic), 140 ? + VAT (1.5h intermediate recommended annually), 180 ? + VAT (2h intensive). Severe cases with disassembly + ultrasound from 580 ? + VAT.
For maintenance Once a year or every 80,000 - 100,000 km in modern diesel cars. Especially if you mostly do short urban trips.
Yes, totally safe if performed by a workshop with calibrated professional equipment. It doesn't damage probes, sensors, or the catalytic converter. On the contrary, it benefits them.
S. Preventive engine decarbonization improves combustion, reduces the amount of soot reaching the DPF, and extends its lifespan. Combined with good oil and filters, it prevents most blockages.
When the intake is cemented (petrified carbon), mechanically stuck EGR valve or clogged EGR cooler. A prior diagnosis confirms this. Cost from 580 € (commercial vehicles) or 980 € + VAT (high-end vehicles).
