Dubai Mercedes C63 Cam Adjuster Replacement Service
Engine Ticking in Your Mercedes C63? It Is Not Just Noise, It Is a Warning.
That sharp metallic tick-tick when you start your C63? It is not harmless. It is your cam adjuster failing, and ignoring it could cost you the entire engine.
We have seen it firsthand at our Mercedes-specialist garage in Dubai. One client brought in his C63 after months of strange sounds. Diagnosis? Worn cam adjusters. The result? Thousands in repairs that could have been avoided.
At our workshop, we focus only on Mercedes models. No shortcuts. No guesswork. When it comes to Mercedes C63 cam adjuster replacement, we use original parts not just OEM and every job includes proper timing, inspection, and post-repair testing. We have done it for dozens of C63s across Dubai, from Business Bay to Al Quoz.
Fact | A failing cam adjuster throws off your valve timing. That means poor throttle, engine knocking, and long-term wear.
Do not wait for the check engine light. If you hear ticking, feel rough idling, or notice sluggish power, book a proper cam adjuster inspection now. We know the M156 engine. We know the Dubai driving conditions. We fix what other garages miss.
Mercedes C63 cam adjuster replacement done right, done once, with full clarity.
Why the Cam Adjuster Matters in Your Mercedes C63?
The cam adjuster controls valve timing. In a performance car like the Mercedes C63, that means it decides how well your engine breathes and how fast it responds. If timing is off, everything feels wrong: power drops, fuel use spikes, and engine noise creeps in.
C63 owners often first notice a ticking noise. Then comes hesitation. Then the check engine light. We have seen it many times at our garage here in Dubai.
Fact: The M156 V8 in your C63 puts more strain on the cam adjuster than most engines. High pressure, high heat, aggressive driving, it all adds up.
That is why Mercedes C63 cam adjuster replacement is not just common. It is necessary. And if it is not done right, damage spreads fast, especially in the UAE’s tough driving conditions.
We replace cam adjusters using original parts, reset cam timing, inspect your timing chain tensioner, and run a full test. We fix it the way it should have come from the factory.
When the Engine Talks - You Need to Listen
If your Mercedes C63 sounds like a sewing machine at startup, do not ignore it. That ticking? It is the cam adjuster losing grip. And when it fails, the valve timing falls apart, along with your performance.
Most drivers notice it like this
- The engine ticks for 20–30 seconds after a cold start
- The throttle feels lazy, especially at low RPMs
- Occasional misfires or a rough idle
- The check engine light flashes on and off without warning.
We once had a C63 come in from Motor City driver thought it was “just a bad oil.” It was not. The adjuster had failed, and the timing chain was wearing out fast. If he had waited another week, it would have meant full camshaft replacement.
Tip: Engine damage from delayed cam adjuster replacement is real. And expensive.
How do We Replace the Cam Adjuster in a Mercedes C63?
The Right Way, Every Time. Mercedes C63 cam adjuster replacement is not just about changing a part. It is about restoring your engine’s timing precision. Miss one detail, and your C63 can lose its edge or worse, suffer long-term damage. That is why we follow a strict, step-by-step process built around this engine’s real-world behavior, especially in the UAE’s brutal conditions.
1. Diagnostic Inspection and Fault Code Scan
We begin with a full scan using dealer-level diagnostics. This is not a plug-in; I guess it is a detailed check of camshaft timing values, sensor responses, and misfire history. If the cam adjuster is failing, we usually spot advanced VVT (Variable Valve Timing) errors and deviations in cam angle data.
2. Valve Cover Removal for Direct Access
Once confirmed, we remove the valve covers to inspect the physical condition of the cam adjusters. This reveals any wear on the lobes, excessive play, or oil sludge buildup from degraded seals. On the M156 engine, clearance is tight, so disassembly is methodical to avoid damaging delicate wiring harnesses or breather lines.
3. Camshaft Locking and Timing Mark Setup
Before anything is removed, we lock both intake and exhaust camshafts using precise timing tools. This prevents rotation and ensures that once the new adjuster is in, the timing remains accurate. The camshaft position must align with Mercedes factory spec, no guesswork.
4. Releasing the Timing Chain Tensioner
We carefully release pressure from the timing chain tensioner. This allows controlled access to the adjusters without pulling the entire chain assembly. Tensioners are checked for smooth operation, and we look for stretch indicators in the chain itself. If anything shows abnormal wear, we notify you before proceeding.
5. Removal of Worn Cam Adjusters
Now comes the core step, removing the damaged adjusters. We inspect the splines, oil ports, and mechanical advance mechanism inside. Often, we find wear caused by oil breakdown or heat stress from long Dubai commutes. Broken springs, delayed advance timing, and scoring are common issues.
6. Installing Original Cam Adjusters (Not OEM Alternatives)
We do not use random OEM parts sold under generic branding. We install original cam adjusters, made to the same standards Mercedes installs at the factory. Why? Because OEM parts often skip quality control, especially in variable timing systems.
7. Resetting Camshaft Timing and Verifying Alignment
With the new adjusters in place, we rotate the crank manually to confirm alignment. We reset the camshaft timing values and rechecked all marks using Mercedes cam position graphs. There is no room for error here; one degree off, and the engine starts misfiring under load.
8. Final Chain Tension Check and Assembly
Before closing everything up, we check the timing chain tension, tensioner rebound, and listen for any unusual resistance. If chain guides or tensioner shoes show scoring or warping, we replace them immediately no cut corners. The valve covers are resealed with high-heat gaskets to prevent future leaks.
9. Engine Start-Up and Timing Verification
Once assembled, we fire the engine and immediately check:
- Cold idle RPM stability
- Camshaft advance delay using live data
- Oil pressure at startup
- Engine sound tick-free, smooth, no misfires
We test it under various RPM ranges and scan again to confirm all cam timing parameters are restored.
Why the C63’s Cam Adjusters Fail So Often - Especially in Dubai
The Mercedes C63 runs hard. The M156 engine is not gentle on its internals, and the cam adjusters take the biggest hit.
These parts control your valve timing, constantly shifting under load. In Dubai’s traffic, with high heat and stop-go driving, they wear out faster than most owners expect.
Fact: We have replaced cam adjusters on C63s with just over 45,000 miles.
Here is why
- High-performance stress – The cam adjuster is always active, adjusting valve timing at speed. That constant motion leads to early fatigue.
- Extreme UAE heat – Oil breaks down faster, causing sludge. Blocked oil ports inside the adjuster = failure.
- Old design flaws – Many C63s still run the earlier version of the adjuster with weak seals and poor durability.
If your C63 is hesitating, ticking, or lighting up the dash, it is not random. You probably need a Mercedes C63 cam adjuster replacement before things get worse.
Why C63 Owners Across Dubai Trust Us for Cam Adjuster Replacements?
You would be surprised how many Mercedes C63 owners walk into our garage after getting burned by another workshop. We hear it all the time: “They said it was a quick fix.” Or worse, “They replaced it, but now it sounds even worse.”
The reality? Mercedes C63 cam adjuster replacement is not a side job. It is one of the most sensitive procedures on the M156 engine. Mess it up, and you’re looking at camshaft damage, timing chain failure, or engine timing that’s completely out of sync.
One C63 from JVC came in after just two weeks at another shop, both cam adjusters were installed out of phase. The engine barely started. We had to strip everything back and redo it from scratch.
That is not how we operate.
Here is why C63 owners across Dubai Business Bay, Jumeirah, Motor City, and Al Quoz come to us:
1. We Specialize in Mercedes-Benz, Not Just “German Cars.”
This is not a general garage. We work only on Mercedes models, and we know how the C63 behaves under stress. That includes real-world conditions in Dubai traffic and heat, not just factory test scenarios.
2. Original Cam Adjusters Only, Never Generic OEM
OEM parts sold by third-party manufacturers often look the same, but they do not perform the same. We install original cam adjusters, the same spec Mercedes installs during production, with tighter tolerances and stronger internals.
Fact: Most cam adjuster failures we see are either due to missed oil service or low-quality aftermarket parts.
3. Full Cam Timing Reset and Verification
We do not just replace the adjuster and hand back the keys. Our team resets your camshaft timing, verifies cam angles using live data, and does a test run to make sure throttle response and timing performance are restored.
4. No Surprises, No Guessing
Before we start, we walk you through every step. If we see other wear chain guides, bolts, or tensioners, we will show you. Nothing is changed without your approval, and nothing is guessed.
5. Real Experience with the M156 Engine
This engine has quirks. Timing marks are sensitive, cam bolts stretch under torque, and valve cover gaskets often leak if reused. We have done this job again and again. We know what fails and how to get it right the first time.
In short, this is not about selling a service. It is about giving your AMG the kind of repair it was built to expect. Mercedes C63 cam adjuster replacement is not where you want shortcuts, and with us, you never get them.
Got it. Here’s a more refined version of Section 7 that focuses on cost in paragraph and tabular format, keeping it clear, precise, and matched to your Dubai market and Mercedes C63 owners:
How Much Does Mercedes C63 Cam Adjuster Replacement Cost in Dubai?
Most Mercedes C63 cam adjuster replacement jobs in Dubai fall between AED 3,800 and AED 7,500. The final cost depends on what exactly your engine needs once we inspect it. Some C63s only require a single adjuster change. Others need both adjusters, a full timing reset, and supporting parts like chain guides or tensioners replaced.
This is not a basic oil change it is engine timing work on a high-performance AMG motor. And if done wrong, it can cause more damage than it fixes.
Unlike garages that hand you a vague quote with no breakdown, we show you what you are paying for. Here’s a realistic cost range based on actual jobs we’ve done at our Dubai Mercedes garage:
Estimated Cam Adjuster Replacement Cost – Mercedes C63
Service Detail | Estimated Cost (AED) |
Full diagnostic scan & engine inspection | 300 – 500 |
Single cam adjuster replacement (parts + labor) | 3,800 – 4,500 |
Both cam adjuster replacements | 5,000 – 6,000 |
Add-on: Camshaft bolt & tensioner (if worn) | 300 – 700 |
Add-on: Timing chain guide replacement (if needed) | 500 – 900 |
Full job (both adjusters + timing reset + parts) | 6,500 – 7,500 |
This includes:
- Original cam adjusters (not aftermarket or low-grade OEM)
- Timing chain tension check
- Precise camshaft timing reset
- Engine testing & live data verification
- Post-repair test drive and report
Tip: Delaying cam adjuster replacement might save you AED 2,000 now, but cost you AED 12,000 later in engine repairs. We’ve seen it happen more than once.
We always inspect first. If everything checks out clean, we’ll quote you for just what needs to be done, no upsells, no pressure.

Mercedes C63 Cam Adjuster Replacement – FAQs
Most jobs take 1 to 2 working days. If you are only replacing one cam adjuster and no other components need attention, it can be quicker. If chain tensioners, bolts, or guides show wear, we may need a bit longer to complete the job properly.
Technically, yes. But should you? Absolutely not. Delayed replacement can throw off camshaft timing, cause misfires, or damage the chain and cams. We have seen cars driven too long end up with full valvetrain repairs.
Simple your C63 should be quiet on cold starts, idle smoothly, and the throttle should feel crisp again. We also provide live timing data before and after the job, so you can see the difference, not just feel it.
Only original. Not generic OEM. OEM-sold adjusters are cheaper, but do not hold up in the M156 engine. We use factory-spec original cam adjusters, the kind Mercedes installs during production.
We often see failures between 45,000 and 65,000 miles, especially in UAE conditions. If your car’s past that and has not had this done, it's time for a check, even if it seems fine now.
Tip: Don’t wait for major symptoms. Book a timing inspection if you’re unsure. It’s quick, and it might save you from a bigger repair bill later.
