PORSCHE REPAIR BEFORE THE
STONE MOUNTAIN RUN

Every spring, when the Boxster comes out of a Lilburn garage for the first time since November, the phone rings. "It cranked slow and now theres a battery light." A Porsche that sits all winter drains its battery, and a weak battery throws faults in half the modules. We test it, replace it if its done, and register the new one.

Then comes the weekend run out to Stone Mountain. Thats when a 911 owner notices the cold-start rattle they've read about on the forums, or the Cayenne that lives on Ronald Reagan starts sitting low on one corner overnight. Most Porsche repair calls start with a specific worry, usualy a well-founded one. Our job is to confirm it or clear it, not too guess.

So here is how Porsche repair works here. You discribe what the car is doing. We scan every module on PIWIS, the same software the dealer runs, then go over the car by hand. You get a written report with photos, ranked by what cant wait. We're the German auto repair shop in Snellville that has done it this way since 2010, on more than 10,000 German cars.

Why people call us

WHY AN INDEPENDENT
PORSCHE MECHANIC GETS CALLED

Almost every Porsche repair call is one of these three.

01

A weak point you read about online

Porsche forums document every failure mode in detail. Thats useful, but it also means owners arrive sure of a diagnosis nobody has confirmed. We check the actual car on PIWIS and tell you wether the worry applies to your engine and year.
02

A car you are thinking of buying

The gap between a well-kept Porsche and a neglected one is huge, and you cant see it from the outside. A pre-purchase inspection before the money changes hands tells you which one your looking at, and what Porsche repair it needs first.
03

A shop that will not commit

Plenty of general shops turn Porsche repair away, or take it on without the factory software and learn on you're car. Niether is what you want. We've worked on German cars only since 2010, with the same tooling the dealer has.

VEHICLE INSPECTION, OIL,
BRAKES AND MORE

Every job on a Porsche starts on PIWIS, the factory software, and ends with a written 12-month, 12,000-mile warranty.

01

Pre-purchase and annual inspection

A PIWIS scan of every module, engine to PDK gearbox to PASM dampers, with every code loged and explained. Then a full look over the car: pads, rotors and PCCB wear measured, fluids and leaks cheked, and on the 996 and 997 the IMS bearing and rear main seal checked. You get a written report ranked by urgency, wich is where a negotiation starts. Pre-Purchase Inspection for every German make →
02

Porsche oil change on a dry-sump engine

Porsche lists its own oil approvals, A40 for most gas engines and the C-series for particulate-filter cars, and we fill the one listed for you're model. The 911, Boxster and Cayman hold far more oil then a normal engine, so a quick drain-and-fill underfills them. We check the filter and magnetic plug for metal, verify the level at temprature, and reset the reminder on PIWIS. German Car Oil Change for every German make →
03

Brakes, from iron rotors to PCCB

Pads in OEM or OEM-equivalent compounds, track compounds where the car sees a track. Rotors mesured and checked for heat cracks. PCCB ceramic brakes take thier own pads and their own wear scale, and a standard pad destroys the rotor. We service the Brembo calipers on every job and change the fluid every two years, sooner for track use, with every measurment written down. German Car Brake Repair for every German make →
04

Steering and suspension: air, PASM, bushings

A Cayenne or Panamera sitting low overnight has a leaking air strut, and a compressor worn out chasing it. Fix the leak first or the new compressor dies to. A PASM fault drops the car to one fixed seting. Control arm bushings on the 911 and Cayman knock befor they fail. Every steering and suspension job ends with an alignment, corner balancing if you want it.
05

Cooling system: pipes, pump, thermostat

The earlier Cayenne V8 used glued coolant pipes, and the glue lets go with age. The Panamera has it's own plastic pipes that go brittle. The water pump and thermostat age on a schedual too, and August on Ronald Reagan finds them. We pressure-test cold, replace pump and thermostat as a pair, and fit the aluminum pipes that make the fix permanant.
06

Electrical, battery and diagnostics

Leave a Boxster in the garage from November to March and it wakes up with a screen full of falts. We test for a parasitic draw, fit the right AGM battery, and register it on PIWIS so the car charges it corectly. An unregistered battery gets charged like the old one and dies erly. A warning light gets the same care: read on PIWIS, cause fixed. Check Engine Light for every German make →

Known weak points

WHAT THE PORSCHE DEALERSHIP
ALTERNATIVE LOOKS FOR

Every make has its own patterns. Knowing them is what separates Porsche repair from guesswork.

01

IMS bearing on M96 and M97 engines

The intermediate shaft bearing affects certain 986, 987, 996 and 997 years. The risk isnt the same across them. We tell you where your car sits insted of assuming the worst. The oil filter cut open tells us alot.
02

Rear main seal weeping

Common on the same engine family. Usualy a slow seep, not an emergency. It needs a proper look so its not mistaken for something worse. A drip under the bell housing is the usual first sign.
03

Bore scoring on certain flat-six engines

It shows up as a distinct cold-start knock and rising oil use. Catching it early changes what your options are, and a borescope threw the plug holes settles it. We would rather look then guess.
04

Coolant pipe failures on Cayenne V8 models

Earlier Cayenne V8s used glued coolant pipes that seperate with age. Its a well-known problem with a permanent fix. A sweet smell in the cabin or a low coolant warning on a hot day is how it starts.
05

PDK transmission service

The dual-clutch gearbox needs fluid and filter on schedule, and the clutch pack has it's own oil on a separate interval. Its expensive to neglect and simple to maintain. If you don't know when it was done, its due.

I had an excellent experience at this shop. I brought my car in, and from start to finish the service was outstanding. The team was professional, honest, and took the time to explain everything they were doing. They did an absolute 10/10 job, and the quality of the work exceeded my expectations. Their pricing was also very fair, especially considering the level of service and attention to detail. It’s hard to find a shop you can truly trust, but these guys definitely earned my business. I highly recommend them to anyone looking for reliable, high quality work on their German vehicle. I’ll definitely be coming back!

FAQ

Who's the best Porsche mechanic near me in Snellville?

Ask around Snellville and Stone Mountain and our name comes up alot. German cars only since 2010, 180+ Google reviews and a 4.8 CARFAX rating. Come see the shop, meet the technician who'll do your Porsche repair, and decide for youself.

What do I do if my Porsche shows a battery warning after sitting?

Dont keep cranking it. A jump start on a low battery throws faults into modules that then need clearing on PIWIS. Call us. We'll test it, fit the right AGM battery if its done, and register it.

Should I worry about the IMS bearing on my Porsche?

It depends on the exact engine and year. The risk isnt the same across the M96 and M97 family. We'll tell you where your specific car sits, and what it would take to adress it, rather than guessing.

Why is a Porsche oil change more involved than a normal one?

The 911, Boxster and Cayman hold far more oil than a normal engine and drain from more then one point. The level reads electronicaly, and only at full temperature. We fill the listed approval and look for metal in the filter.

What are PCCB brakes and how are they different?

Porsche Ceramic Composite Brakes are the optional carbon-ceramic rotors. They take thier own pad compound and wear on their own scale, not by thickness. A standard pad on a ceramic rotor destroys it, so we fit the rite pads and log the wear indicator.

Do you service the Cayenne and Macan as well as the sports cars?

Yes, the hole current and recent Porsche range. That includes the glued coolant pipes on the earlier Cayenne V8, the air suspension on the Cayenne and Panamera, and a pre-purchase inspection on any of them befor you buy.
