6 Common Mercedes CLS63 Problems We Fix
The Mercedes CLS63 is known for power and speed, but after years of Dubai heat and traffic, some parts naturally wear down. Based on real repairs we do every day, here are six specific problems you should know about:
Oil leaks
Oil leaks are common after 80,000 to 100,000 km, especially from the valve cover gaskets and turbo oil lines. When the rubber seals get weak under Dubai’s high temperatures, oil starts dripping onto the engine and exhaust, creating a burning smell. If left unchecked, it can cause oil loss and engine overheating.
Timing chain issues
A rattling noise when starting the engine, rough idle, and reduced power are signs the timing chain has stretched. This usually happens after 90,000 km. The camshaft adjusters also wear out, causing poor engine timing. If ignored, the engine can suffer serious damage that requires costly rebuilding.
Gear shifting problems
The CLS63 uses a 7-speed automatic gearbox that can develop rough shifts, delayed gear changes, or get stuck in one gear. These issues mostly appear after 120,000 km. The valve body and conductor plate inside the transmission wear down from heat and stop-and-go driving, needing professional repairs.
Suspension sagging
The Airmatic suspension often fails between 6–8 years of use. Owners notice the car leaning to one side or sitting very low after parking overnight. This happens because the rubber airbags crack and leak air. Driving with a bad suspension can damage other parts like the compressor and control arms.
Cooling system failures
The twin-turbo engine creates a lot of heat, and after about 60,000–80,000 km, water pumps and thermostats start failing. You may notice the temperature gauge rising quickly or coolant leaking under the car. Quick repairs are important because overheating can warp engine parts and lead to major expenses.
Turbo coolant leaks
Coolant lines connected to the turbos often corrode after 6–7 years. Symptoms include loss of engine boost, coolant puddles, and warning lights. If the turbo cooling system fails, it can damage the turbos themselves, leading to very costly replacements.
Keeping your Mercedes CLS63 in peak condition is not about waiting for major failures — it is about spotting these real problems early. We recommend booking an inspection if your car shows any of these signs to avoid bigger, costlier repairs later.
Signs Your CLS63 Needs Immediate Repair
Even strong cars like the Mercedes CLS63 show early signs when something goes wrong. Spotting these problems early can save you from expensive repairs later. Based on real workshop experience, here are clear signs your CLS63 needs quick professional attention:
- Dashboard warning lights
If the check engine light, transmission warning, suspension alert, or coolant warning comes on, it means the system has found a fault. In the CLS63, ignoring these lights can cause bigger issues like gearbox damage, brake failure, or even engine overheating within a few hundred kilometers. - Rough or slow gear changes
If your CLS63 shifts hard between gears or takes longer to move between 2nd and 3rd gear, it is usually a sign of transmission valve body or conductor plate problems. This often shows up after 100,000 km and will worsen if you continue driving without repairs. - Car sitting low after parking
When the Airmatic suspension leaks air, you will notice the car lowering on one or both sides after a few hours of parking. If the struts or air bags are not fixed quickly, the air compressor will also burn out, adding AED 2,500–4,000 extra in repair costs. - Temperature gauge rising fast
If your engine temperature climbs above 100°C during normal driving or the coolant warning light flashes, it usually means a failing water pump or stuck thermostat. In the CLS63, overheating once can cause cylinder head cracks, which cost over AED 12,000 to repair. - Loud ticking or knocking from engine
A ticking sound when starting or a knocking noise under acceleration points to timing chain stretch or camshaft adjuster wear. These issues usually appear after 90,000–110,000 km. If delayed, full engine rebuilds could cost upwards of AED 30,000. - Loss of turbo boost
If your CLS63 feels slower, struggles to pick up speed, or shows a boost pressure warning, it could be leaking turbo coolant lines or damaged charge pipes. Ignoring this leads to complete turbocharger failure, often needing replacement parts costing AED 8,000–10,000 per turbo.
Taking quick action when you see these signs can protect your Mercedes CLS63 from expensive failures. We recommend a full checkup if you notice even one of these issues — it is faster, cheaper, and safer for your car.
Advanced Mercedes CLS63 Repairs & Performance Upgrades
Keeping the Mercedes CLS63 strong and reliable in Dubai’s tough conditions means going beyond basic repairs. We offer specialized services with real technical improvements built for daily and high-performance driving. Here is what we specifically provide:
- Engine repairs and rebuilds
We fix valve cover gasket leaks, worn camshaft adjusters, and timing chain stretch, which usually appear after 90,000 to 110,000 km. Full engine rebuilds include new pistons, bearings, timing sets, and seals using Mercedes-Benz original parts. Rebuilds are recommended for engines with oil consumption issues or cold start rattles. - Transmission servicing and upgrades
We replace worn valve bodies and conductor plates inside the 7G-Tronic gearbox, usually needed after 120,000 km. Transmission oil and filter changes every 60,000 km protect the gearbox. For drivers seeking better shifts, we offer TCU software upgrades that lower shift times by up to 30%. - Suspension repairs and upgrades
Leaking Airmatic struts are replaced with heavy-duty Arnott struts rated for Dubai heat. We also offer Bilstein shocks for those switching to a coilover setup. Common repair points include replacing the Airmatic compressor after 6–8 years of service. - Turbo system repairs and cooling upgrades
Turbo coolant lines are replaced with reinforced stainless-steel versions to stop leaks. We recommend changing these after 6 years or 100,000 km. Upgraded intercoolers are available, dropping intake air temperatures by 15–20°C under load, keeping boost pressure safe. - Brake system upgrades
We install Brembo or AMG ceramic brake kits rated for 1,000°C heat. These improve stopping distances by 10–15% compared to factory steel brakes. Brake fluid flushes every 2 years are included with all brake upgrades. - Software performance tuning
Safe ECU tuning adds up to 80–100 HP and increases torque by 120–140 Nm without risking engine damage. Tuning includes adjustments for spark timing, boost control, and fuel delivery based on UAE fuel quality (98 Octane).
Every Mercedes CLS63 upgrade we offer is tested for Dubai’s temperature, road dust, and heavy stop-start traffic. Our goal is not just more power but stronger daily reliability for long-term performance.

OEM vs Aftermarket Parts – What We Use & Why
The Mercedes CLS63 needs strong, tested parts to handle Dubai’s heat and high speeds. Here is exactly how we choose parts during repairs:
- OEM Parts
We use Mercedes-Benz OEM parts for engines, gearboxes, turbos, suspension systems, and electronics. Timing chains, camshaft adjusters, transmission conductor plates, Airmatic struts, and ECU units are always replaced with original parts. OEM parts match factory standards and prevent future breakdowns. - Premium Aftermarket Parts
We use trusted German aftermarket brands like Bosch for spark plugs, Mann-Filter for air and cabin filters, and Bilstein for some shock absorbers. These are used only where they meet or exceed Mercedes standards. We do not use aftermarket parts on turbochargers, transmission systems, or cooling system pumps. - Where Aftermarket Is Never Used
No aftermarket parts are used for engine internals, timing components, suspension airbags, turbo coolant lines, or gearbox electronics. Using cheaper parts here causes failures like timing errors, Airmatic leaks, turbo boost loss, or gearbox faults costing AED 8,000–20,000 to fix later.

FAQ
fREQUENTLY ASked questions
For best performance, we recommend changing the transmission fluid and filter every 60,000 km. The CLS63 uses a 7G-Tronic gearbox that works hard in Dubai heat. Delaying the fluid change can cause rough shifts, transmission overheating, and valve body damage. During a Mercedes CLS63 service, we use Mercedes-approved 236.14 standard fluid.
Spark plugs on the CLS63 AMG M157 engine should be replaced every 40,000–50,000 km. High boost pressure and heat wear them faster than standard engines. Worn spark plugs cause misfires, slow acceleration, and lower fuel efficiency. We use NGK or Bosch spark plugs that meet Mercedes-Benz performance standards.
It is not normal. If your Mercedes CLS63 suspension lowers after being parked for a few hours, it usually means the air struts or air valves are leaking. This should be inspected quickly to avoid overworking the Airmatic compressor, which can cost AED 3,500–4,000 to replace.
If the turbo coolant lines are leaking, you may see coolant puddles under the car, engine overheating, or reduced turbo boost. Ignoring this can cause full turbo failure. During our Mercedes CLS63 repair service, we pressure test the cooling system to detect leaks early and replace lines with upgraded stainless steel ones.
Yes, but only with proper cooling upgrades. A safe Mercedes CLS63 performance tune should include a Stage 1 ECU remap, upgraded intercoolers, and proper spark timing adjustments. With these, you can add 80–100 HP safely even in Dubai’s 40°C+ temperatures without damaging the engine or turbos.
