Independent Mercedes care · Al Quoz, Dubai
Get lighting, wipers and other body-electrical functions working reliably again. We investigate SAM faults, repair suitable units and arrange compatible replacement and setup when repair is impractical.
STAR diagnostics and circuit checks help distinguish a failed module from a supply, wiring or connected-component fault.
SAM repair is estimated at AED 950–1,600 including VAT for a suitable repairable unit, removal, refitting and relevant function checks.

A SAM manages body-electrical signals and outputs; its responsibilities vary by vehicle. Repair, software work and replacement are different services, so the right starting point is the fault found on your car.
Planning estimates for the stated work, not fixed tariffs. Initial fault diagnosis is typically AED 200–350 including VAT and is listed separately. The written quote identifies any diagnostic or setup work already included. The first-service offer has not been deducted.
Get better prices for a SAM repair. Tell us your Mercedes model and which functions are failing. We will explain the next step and the work included.
Tell us what stopped working and whether it is constant or intermittent. That description helps us plan checks around the fault you want repaired instead of selling a module from a warning message alone.
A bulb or lamp assembly, motor, fuse, wiring connection or control signal may be responsible. We test the relevant circuit before pricing a module. That can identify a smaller repair, or provide a sound reason to replace a damaged controller.
A weak supply or communication problem can affect more than one function. The diagnostic findings are considered together so a collection of stored fault codes is not treated as proof that several expensive modules have failed.
An electrical component may remain active when it should not. We investigate the current draw and the relevant circuits. The SAM can be involved, but the symptom alone does not establish whether the module, another unit or an added accessory is responsible.
We inspect the relevant electrical connections and module area when a fault follows water entry. Drying the visible surface does not establish that the circuitry and terminals remain reliable. Corrosion or damage may persist after the function temporarily returns.
The repair plan must address how moisture reached the unit. Depending on the car and findings, that may involve seals, drainage, a damaged housing or another body leak. Replacing the SAM while leaving the water-entry problem active can expose the new part to the same conditions.
A connector or nearby loom can need its own repair. We explain whether the quoted work covers the module alone, the terminals and wiring, or both. That distinction is especially useful after a previous repair, because repeated symptoms do not automatically mean the replacement module is faulty.
Tell us about recent rain exposure, washing, a wet carpet or work near the relevant area. These details help guide the inspection. If you notice an electrical burning smell, smoke or heat from a damaged connection, stop using the car and call about safe recovery.
We assess the actual condition before offering component-level repair. A suitable localized fault may be repairable while retaining the original unit. The work should have a defined purpose, such as restoring the identified output or correcting an established internal fault, rather than simply clearing messages.
Severe corrosion, extensive heat damage, unsuitable hardware or an unsuccessful earlier modification can make a reliable repair impractical. We explain that finding and compare an appropriate replacement. Spending less on a repair is useful only when the repaired unit is suitable for the required job.
The price depends on the assessed unit and the work needed. We do not describe every SAM as repairable or promise that repair avoids all coding. Where the module cannot be reliably assessed until it is removed, we identify that stage and the cost before proceeding.
Ask us to check a replacement before you buy it. A low parts-only price can become expensive if the unit cannot be used in your vehicle.
Mercedes vehicles use different SAM arrangements. A front or rear SAM is selected according to the vehicle and the circuits it serves, not simply by its position in a search result. We identify the relevant unit on your car and check its part information before recommending a replacement.
If a module has already been replaced elsewhere, send the invoice or available part details when convenient. We can investigate whether the remaining problem relates to compatibility, installation, setup or an unresolved vehicle fault. We do not assume that another software session will correct a wrong or damaged part.
A fuse housing or connector can show damage that matters to the final repair. The supply and connected circuit need to be suitable before a repaired or replacement module is put back into use. We include the relevant electrical checks in the repair plan and explain any separate wiring work.
If an aftermarket accessory has been installed, tell us what it is and when it was fitted. Its wiring may be relevant, particularly when the symptoms began soon afterward. The purpose is to locate the fault; the presence of an accessory alone does not establish that it caused the damage.
A useful estimate distinguishes the controller, connectors, loom repairs and any other failed component. It also explains whether module removal, refitting and setup are included. This makes it easier to compare a repair with replacement and avoids a low parts-only figure being mistaken for a finished job.
When the fault extends beyond the SAM, our Mercedes electrical repair service can cover the related circuit work. Other controller problems are assessed through our Mercedes module repair and coding services.
After the agreed work, we check the original complaint and relevant linked functions. A lighting repair should include checking the required lighting behavior; a repaired electrical supply needs appropriate verification under the conditions involved. The final checks follow the actual job.
Clearing fault memory can be part of the procedure, but an empty fault list alone is not proof that an intermittent problem has been resolved. We explain what was checked and any further observation that is needed.
A fault that occurs only after parking or with particular equipment may need a longer observation period. Tell us how often it happens and the conditions you have noticed. That helps us plan workshop time without promising a same-day fix for a problem that has not yet been reproduced.
Parts availability, removal work, the required setup and functional checks affect collection time. We agree the expected timing for the confirmed job and explain the warranty applicable to the selected repair or replacement.
Answers about repairability, replacement and software work before you book.
A suitable SAM repair is estimated at AED 950–1,600 including VAT, with the agreed repair, removal, refitting and relevant function checks. Initial diagnosis and separate wiring, water-entry or replacement work are itemized where required.
It can be involved in an electrical drain, but a flat battery does not prove SAM failure. We investigate the source of the draw and related circuits before selecting the repair.
Only where the exact application and unit support the required procedure. Some units have compatibility or commissioning restrictions. Contact us before purchasing a used module so we can check its suitability and the available setup procedure.
Coding does not repair physical corrosion or burned connections. Water-damaged hardware needs assessment, and the source of water entry must be addressed. The appropriate result may be a repairable unit, wiring work or a replacement.
Start by contacting us with the model and symptoms. Vehicle-level checks are often needed to distinguish a module fault from its supply, wiring or connected components. We will tell you whether a removed unit can be assessed for the requested work.
Yes. Tell us what was replaced and what still fails. Part details, a prior invoice or diagnostic information can help, but they are not required for the first call. We assess compatibility, installation and the unresolved vehicle concern.
Call MercGarage with your Mercedes model and the functions that are not working. If the problem followed water entry, a battery incident, accessory installation or a previous module replacement, mention it. You do not need to identify the SAM location or part number yourself.
Our workshop is at 39, Al Quoz 4, Dubai. We explain the findings and the cost of the appropriate repair, supported software work or compatible replacement. If the car will not start or cannot be driven safely, ask about recovery arrangements and charges when you call.
