AC leak test and recharge
The selected test and charge depend on the actual system. Do not repeatedly recharge a known leaking system; repair its confirmed source.
AED 250 to 450VW Polo Evaporator Replacement in Dubai
Polo AC losing its cold within days of a recharge, a musty smell from the vents or water on the passenger floor? These symptoms can have different causes; a leak elsewhere, moisture, a drain problem or heater-circuit fault must also be considered. We prove the leak first at our Al Quoz 4 workshop, then replace the evaporator, recharge the system and test the vent temperature before you collect.
Evaporator replacement AED 1,800 to 2,500. Indicative Dubai price for the Polo Mk5 and Mk6. The recharge and any seals are listed on the same written quote.
- Leak proven before work
- Written quote first
- Usually 4 to 6 hours
Quick answer
An evaporator is replaced when testing establishes a fault that needs replacement. Fast refrigerant loss can occur elsewhere, and musty smells alone usually call for moisture, drain and cabin-filter checks. Appropriate leak tests identify the source before dashboard work is quoted. A leak test and recharge is AED 250 to 450 and evaporator replacement is AED 1,800 to 2,500, on a written quote.

Before you approve a dashboard-out repair
Is it the evaporator, or something else?
Many Polo AC faults feel the same from the driver seat. Symptoms guide the checks; they do not identify a failed component by themselves.
Find the source
Leak, smell or wet carpet?
These symptoms need different checks before an evaporator is recommended.
- Cold air fades within days of a rechargeRefrigerant loss can be at the evaporator, condenser, pipes or connections; test the source.
- Musty or chemical smell from the ventsInspect moisture, drainage and the cabin filter. Odor alone is not an evaporator-leak test.
- Water on the passenger floorCheck the condensate drain, water ingress and heater circuit; wet carpet alone does not justify a new evaporator.
- Oily film on the inside of the windscreenInvestigate the source, including heater-circuit leakage or interior contamination; do not assume it is refrigerant oil.
Check the wider AC system
Cooling or airflow changed?
Airflow, refrigerant charge and AC controls can produce similar complaints.
- Cold while driving, warm at traffic lightsAssess condenser airflow, fan operation, refrigerant charge and compressor control. See Polo condenser replacement.
- Weak cooling after a whole summerCheck cooling performance and refrigerant condition; AC systems are not routinely topped up without considering leakage. See Polo AC recharge.
- Little air from the vents at any speedCheck the cabin filter, blower operation and airflow restrictions.
- Click and no cold at allCheck compressor regulation, electrical control and other AC faults. Compressor designs vary.
Start with the symptom
Unsure whether your Polo needs an evaporator?
Tell us when the AC loses its cold, whether it was recently recharged and any smell or water you notice. We explain the checks before quoting the repair.
What the evaporator does in your Polo
It is the part that actually makes the cabin air cold, and it sits in the hardest place to reach.
Where it sits
Inside the heater box, behind the dashboard. Access may require dashboard and heater-box removal. The required procedure depends on the fitted version and explains much of the labor.
Why it fails in Dubai
Corrosion or physical damage can affect the core. Moisture and debris can also cause odours or drain problems without a refrigerant leak; testing distinguishes these faults.
What gets replaced with it
New O rings and seals, and the expansion valve or drier when the test shows they are contaminated or worn.
Polo AC systems by year
Evaporator fitment, refrigerant and oil requirements vary by production version and market. We identify the actual system before ordering or charging.
| Polo | Common engines | Refrigerant | What we see most |
|---|---|---|---|
| Mk5, 2010 to 2017 | 1.6 and 1.4 petrol, 1.4 TSI on some trims | R134a on most UAE cars | Evaporator leaks on high mileage cars and blocked drains. |
| Mk6, 2018 onwards | 1.6 petrol, 1.0 and 1.4 TSI depending on market | R134a or R1234yf, depending on year and market | Musty smells, cabin filter neglect and condenser stone damage. |
| Polo GTI | 1.4, 1.8 and 2.0 TSI | Depends on year and market | Confirm the engine, body and AC specification; the GTI badge alone does not establish leak risk. |
Check the bonnet label. The sticker under the bonnet shows the refrigerant type and the exact gas weight for your Polo. We read it before any recharge and use the matching gas and oil.
How we replace a Polo evaporator
Most cars are ready the same day when the part is in stock.
- Prove the leakUse appropriate visual, electronic and compatible-dye or trace-gas tests as needed, including the drain or vent area where suitable. Pressures alone do not locate a leak, and the other components are checked too.
- Recover and stripWe recover the refrigerant, disconnect the battery and remove the dashboard and heater box with care for clips and airbags.
- Fit the new evaporatorGenuine or OEM evaporator with new seals, plus the expansion valve if it is contaminated. The drain is cleared and checked.
- Vacuum, recharge and testCheck repaired-system integrity using appropriate tests, evacuate and recharge to the specified weight, then verify cooling and relevant fault data. A vacuum hold alone does not rule out every leak.
Polo evaporator questions
Straight answers before you book in. More Polo jobs are on our Volkswagen Polo repair page.
How much does a VW Polo evaporator replacement cost in Dubai?
Typically AED 1,800 to 2,500, depending on the year and the parts needed. The refrigerant recharge and any seals or expansion valve are listed on the same written quote before work starts.
How long does the job take?
The existing fitting estimate is four to six hours for a straightforward quoted application after diagnosis and parts confirmation. Dashboard and heater-box access depend on the actual version; additional faults or access difficulties can extend the job.
How do you know it is the evaporator and not the condenser?
We test the system using suitable methods and assess the evaporator area along with the condenser, pipes and connections. Electronic detection or compatible dye at an accessible drain or vent can help, but no single pressure reading or negative test settles every case. Dashboard work is quoted only when the findings justify it.
Why does my Polo AC smell musty?
Usually mould growing on the evaporator and a dirty cabin filter. A new filter and an evaporator cleaning treatment often fix it. Replacement depends on confirmed damage or an unserviceable fault, rather than odor alone.
Can I keep driving with a leaking evaporator?
Avoid using an AC system known to be losing refrigerant and arrange diagnosis. Driving suitability depends on the whole vehicle, visibility and symptoms; stop safely for smoke, a burning smell or other serious warnings. Do not assume every cooling or cabin-odor problem is safe to continue with.
Which refrigerant does my Polo use?
Most older Polos use R134a, and some newer Polos use R1234yf, depending on the year and market. Check the bonnet label, which shows the gas type and weight. We use the matching gas and oil.
Polo AC not staying cold?
Tell us how the cooling changes and whether there is a smell or wet carpet; the year is helpful if known. We explain the next checks and guide price before dashboard work is approved.
