Your Mercedes engine was built to go the distance when it’s maintained – but only if the small problems get caught before they become big ones. A weeping cam cover turns into a smoking exhaust manifold. A stretched timing chain starts as a faint rattle and ends as a tow bill. At Hyperformance Garage, we find these problems early because we know exactly where Mercedes engines like to fail.
I’m Dave Garcia, master technician and owner. When you bring your car in, you talk to me – the person who will actually open your hood – not a service advisor reading from a script. I’ve spent my career inside German engines, and Mercedes powerplants are what I know best. From M272 balance shaft issues to the timing chain guides on high-mileage M276s, I diagnose based on pattern knowledge and evidence, not guesswork and parts cannon.
If your Mercedes is leaking oil, making a noise it didn’t make last month, running hot, or just not pulling the way it used to, bring it by our Apex shop. We’ll tell you exactly what’s wrong, what it needs, and what it doesn’t – in plain English, before any work starts.

Mercedes Engine Questions
My Mercedes is leaking oil but the light isn’t on. Can I wait?
Short answer: don’t. Small Mercedes oil leaks almost never stay small – oil migrates onto belts, mounts, and exhaust components and multiplies the repair. Bring it in and I’ll show you exactly where it’s coming from; many leaks are straightforward fixes if caught early.
How do I know if my timing chain needs attention?
Cold-start rattle that fades as the engine warms up is the classic early warning, and certain Mercedes engines are known for chain stretch and guide wear at higher mileage. We can inspect chain stretch data with the scan tool and give you a straight answer – no need to guess.
Do you use dealer parts for engine repairs?
We use quality OEM and OE parts – genuine Mercedes-Benz parts, without the dealership markup. For critical engine components, fit and quality are never compromised to save a few dollars.
Quotes are always free – diagnosis is part of the quote, so there’s no separate diagnostic fee.

Frequently Asked Questions
How much does Mercedes engine repair cost?
It depends on what’s wrong – a failed sensor and a timing component are completely different jobs. That’s exactly why the quote is free: tell Dave the symptoms and the model, and he’ll diagnose it and give you a real number before any work starts. Quotes are always free – diagnosis is part of the quote, so there’s no separate diagnostic fee.
Do you use genuine Mercedes-Benz parts?
Yes. The shop uses genuine Mercedes-Benz parts on Mercedes repairs, and Mobil 1 fluids across the board. On a Mercedes engine, correct parts and correct fluids aren’t optional – they’re what the engine was designed around.
Is engine work covered by your warranty?
Qualifying repairs are backed by our 24-month / 24,000-mile warranty – in writing, on the invoice. Dave will tell you exactly what qualifies before the work starts, so there are no surprises.
What happens when I bring the car in?
Dave road-tests it, runs full diagnostics, and inspects what’s actually failing – not just what the fault code says. You get a clear quote spelling out the problem, the fix, and the cost. Nothing happens until you approve it.
My Mercedes is making a noise / losing power / using oil. How urgent is it?
Don’t ignore it, but don’t panic either – describe it in your quote request and Dave will tell you straight whether it’s safe to drive in or needs attention now. Engine symptoms don’t get better with time, so sooner is always cheaper than later.
