Diagnosis and repair price guide

These published market examples help plan diagnosis and repairs. Mechanics confirms the tests, work and complete total for your vehicle.

Work being considered	Planning price including 5% VAT	What to confirm
Extended electrical diagnosis	From AED 105	A published electrical-diagnosis starting example. A scan alone is different from proving a no-start fault. Agree the tests, time allowance and any further investigation.
Starter motor repair	From AED 210	A published repair starting example after the fault is established. Complete-unit replacement, difficult access, parts and associated damage need a separate fitted total.
Battery supply and fitting	Vehicle-specific quote	Confirm the battery technology and capacity, normal fitting, testing and any registration. A fitting-only charge is not the cost of a supplied battery.
Alternator, fuel, ignition or key-system repair	Quote after diagnosis	Separate repair from replacement and confirm the actual parts, access, programming and tests. One symptom does not establish which job is required.
Pickup, recovery or further fault tracing	Confirm before arrangement	Location, access, transport method, vehicle type and diagnostic time change the total. These charges are not included automatically.

These are indicative market planning budgets, not fixed Mechanics tariffs. The numerical starting budgets include 5% VAT. Your written quote confirms the agreed diagnosis, parts, repair labor and complete total.

Free initial inspection

Start with the free initial inspection advertised by Mechanics to discuss the symptom and the next step. Extended electrical tracing, timed testing, dismantling and recovery are separate when needed. Agree their scope and any charge before they begin.

Approve diagnosis and repair separately

A diagnosis charge does not include replacement parts. Ask which tests are included, whether the charge is credited toward an approved repair and when you will receive the findings.

Arrange a starting-fault assessment

Send the make, model, year, dashboard message and whether the engine cranks.

Describe the failure

What happens when you try to start?

Choose the closest symptom to see what needs checking and describe your enquiry. Inspection establishes the cause.

Check power, connections and the start command

No crank means the engine is not being turned by the starting system. Low battery output, loose or corroded connections, a poor earth, starter supply or solenoid, a relay or fuse, and a missing start-authorisation signal can produce overlapping symptoms. Working dashboard lights do not prove the battery can deliver starting current.

Useful next stepTell us whether there is silence, rapid clicking, one click or slow turning, and whether the lights dim. Avoid repeatedly holding the key or button.

Check what is missing while the engine turns

If a petrol or diesel engine turns at a normal starting speed without firing, assessment moves towards fuel delivery, engine-speed and timing signals, start authorisation and mechanical condition. Petrol engines also need the correct spark. Slow cranking still needs power and starter checks before assuming a fuel fault.

Useful next stepSend the sound of the attempt if safe, the fuel level, warning messages and any earlier stalling. A silent fuel pump or a stored code alone does not confirm a failed part.

Establish why running is not sustained

Starting and then stopping can involve immobiliser authorisation, fuel pressure, air control, electrical supply or an engine fault. Record whether it stops immediately, after warming up or only under a particular condition. A successful restart does not establish that it is ready to drive normally.

Useful next stepStop repeated restarts if it keeps stalling. Tell us about warning lights, recent repairs and any change in engine sound.

Check the correct recognition method

A weak remote-key battery, a missing key signal, a low vehicle supply or a start-authorisation fault may prevent starting. Use your vehicle manual for the backup-key position, which may be in a console slot rather than against the start button. A spare recognised key can provide useful information.

Useful next stepShare the exact display message and whether the spare key changes it. If a key fault is confirmed, see our key fob repair service. Do not attempt to bypass the immobiliser or repeatedly force an unrecognised start.

Read the vehicle-ready state and alerts

A hybrid can be ready to move without its petrol engine running, and an EV has no conventional engine-cranking sound. Check the fitted ready indicator or drive status and record the exact warnings. Low-voltage supply, key recognition or another system fault may need assessment. A traction-battery charge display does not prove every starting system is working.

Useful next stepShare the model, ready/drive status and alerts. Confirm coverage for the vehicle and follow its specified assistance and transport procedure.

Leave it off when damage is suspected

If the engine stopped in water, water ingestion is suspected or the vehicle was submerged, do not try another start or a jump-start. An abnormal mechanical noise, overheating event, smoke or fuel leak also changes the assessment. Rain exposure alone is different from an engine taking in water, but it does not prove restarting is safe.

Useful next stepExplain what happened and arrange suitable recovery or assessment before another attempt. Do not rely on leaving it in the sun as a repair.

Before another attempt

Useful checks and when to stop

Keep the observations that help assessment. Follow the vehicle instructions and avoid forcing a start when damage is suspected.

Confirm the normal starting conditions

With the vehicle safely stationary, follow its normal starting instructions. Check the required selector position, parking brake and brake or clutch input. The appropriate procedure depends on the transmission and ignition system.

Read the exact warning or key message
Check the indicated fuel level and recent refuelling history
Use the manual's backup-key position if required
Note recent battery, alarm, wiring or engine work

Report visible terminal corrosion or damaged cables. Leave electrical testing and handling of suspect batteries to someone equipped for the work.

Know when another attempt is inappropriate

Repeated cranking can drain the battery and overheat the starter. Follow the manufacturer's attempt and cooling limits. There is no universal number of tries that makes a damaged vehicle safe to restart.

Stop for suspected water ingestion or submersion
Stop for smoke, fuel leakage or abnormal mechanical noise
Keep away from a damaged, swollen or leaking battery
Arrange appropriate assistance if traffic or access makes checks unsafe

A jump-start must suit the vehicle, battery chemistry, connection points and equipment. Do not use a generic cable procedure for every car, hybrid or EV.

No crank or repeated flat battery

Check power before choosing a part

Battery, starter and charging faults can overlap. The right tests separate a weak supply from a failed component or missing command.

Checking battery-terminal voltage.

Battery condition and cable losses

Terminal voltage is only one measurement. The assessment should consider battery condition and output under the relevant load, along with the positive connections and earth path. A new battery can still be discharged or connected through a faulty cable.

If a suitable replacement is needed, confirm the correct technology, fitting and registration when arranging battery replacement.

Starter supply and command

A single click does not prove the starter needs replacement. Establish whether supply and the start command reach it, and whether it can engage and turn the engine. A confirmed unit fault may require starter motor repair or replacement.

A missing key-switch start signal may instead need ignition-switch diagnosis, with the wiring and authorisation inputs considered.

Charging and repeated discharge

On a conventional engine, the alternator charges the battery while running. A battery that goes flat again needs the charging system and possible parked electrical drain checked. A successful jump-start is not proof that only the battery is faulty. A confirmed charging fault may require alternator repair.

Petrol and diesel engines

The engine turns, but does not run

Diagnosis should establish which required condition is missing instead of replacing the first part named by a code.

Fuel delivery

Compare the indicated fuel level and fuel supply with the required pressure during starting. The pump, its power and control, delivery restrictions and injection system may need checking. Petrol and diesel systems use different procedures.

A pump noise is a clue, not a complete pressure test. Avoid replacing it solely because a faint hum cannot be heard.

Signals and authorisation

The engine control system needs usable speed and position information. Relevant crankshaft and camshaft signals, wiring, supplies and immobiliser authorisation can affect starting.

Stored codes and live data help direct tests. A code naming a sensor is not proof that the sensor itself is faulty.

Ignition and mechanical condition

Petrol-engine checks may involve spark, coils, plugs and control signals. Diesel starting calls for the appropriate fuel and, where relevant, cold-start system checks.

Unusual cranking, previous overheating or timing symptoms can require mechanical timing or compression assessment. An ignition switch and an ignition coil perform different jobs.

Only fails when hot, after overnight parking or just after a repair? Tell us the pattern. Reproducing an intermittent fault can require a different test plan from scanning a car that is currently starting normally.

From symptom to a written proposal

What the assessment should establish

The result should explain the fault, the suitable repair and what it costs to complete and check it.

Record the failure

Confirm the vehicle, symptom and conditions. Preserve relevant messages and fault information before assuming a part or clearing records.

Agree the testing

Start with the relevant supply, command or running checks. A code scan is one tool. Confirm the initial charge and approval for additional tracing.

Choose the repair

Explain what failed and compare an appropriate repair with replacement. Identify the parts, fitting, programming and testing on the written quote.

Check the result

Recheck starting under the relevant conditions and review related warnings or charging performance where required. Confirm follow-up and written coverage.

Example diagnostic quotations

See what a starting-fault quote can cover

These are illustrative budgets including 5% VAT, not completed customer jobs or fixed offers. Paid testing begins only after its scope and charge are agreed.

Clicking with a confirmed starter fault

Example total: AED 315. AED 105 agreed electrical diagnosis plus AED 210 suitable starter repair. A complete replacement unit, difficult access and recovery are excluded. Confirm whether a diagnosis credit applies.

Engine cranks but will not start

Example testing budget: AED 105. An agreed initial block of electrical fault tracing. Parts and further testing need approval after the findings; this is not a promise to solve every fault within that budget.

Key-not-detected message

Example testing budget: AED 105. Agreed supply and key-recognition checks. New keys, programming and start-authorization modules are quoted separately if the diagnosis identifies them.

Before choosing a part

Starting-fault questions answered

Costs, safe next steps and what the symptoms can actually tell you.

Why won't my car start when the lights still work?

Dashboard lights use less current than an engine starter. They do not prove the battery, cables or earth path can support cranking. Battery output, connections, starter supply and the start command may still need testing. Clicking alone does not identify the failed part.

What is the difference between no crank and crank but no start?

No crank means the engine is not being turned by the starting system. Crank but no start means it is rotating without running. The second pattern directs checks towards fuel, engine signals, authorisation, petrol ignition and mechanical condition, while slow cranking still needs supply and starter checks.

Does starting after a jump mean I only need a new battery?

No. Starting support shows that added supply helped under those conditions. The battery may be discharged because of poor charging, a connection fault, parked electrical drain or its condition. Battery and relevant charging tests are needed before choosing the repair.

How much does no-start diagnosis cost in Dubai?

Published market starts include AED 105 for electrical diagnosis and AED 210 for starter repair, including the source's stated 5% VAT. They are not Mechanics tariffs or complete repair totals for every car. Confirm the initial tests, further tracing, parts, recovery and payable total for your vehicle.

Is a fault-code scan enough to diagnose a car that will not start?

Not always. Codes and live data help direct the investigation, but supply, start command, fuel pressure, sensor signals or mechanical checks may be required. No stored code does not rule out a fault, and a named component code does not establish that the component must be replaced.

What should I do with a key-not-detected message?

Read the vehicle's backup-key instructions and report whether a spare recognised key changes the result. The backup position is model-specific and is not always the start button. A low vehicle supply or recognition fault may also need checking. Do not bypass the security system.

Should I try to start a car that stopped in water?

Do not restart it if water ingestion or submersion is suspected. Leave it off and arrange suitable assessment or recovery. Rain exposure alone is different, but waiting for it to dry does not establish that the engine or electrical system is safe to operate.

Why is my hybrid silent after I press start?

Some hybrids can be ready to move without the petrol engine running. Use the fitted ready or drive indicator and the vehicle's instructions, not engine noise alone. If it does not reach ready status, report the exact alerts and confirm assessment for that model. EVs likewise do not have a conventional cranking sound.

Can you help where the car is parked?

Describe the location, vehicle, access and fault so the appropriate next step can be confirmed. Mechanics offers Dubai pickup, subject to arrangement. Do not assume every fault can be repaired on site or that a call-out, recovery or complex diagnosis is free.

How long does a starting-fault diagnosis take?

It depends on the symptom and how readily it can be reproduced. A simple supply problem and an intermittent hot-start fault need different tests. Confirm the initial investigation time, approval for further tracing and expected collection time after the work and parts requirements are established.
