Common Engine + Transmission Problems in BMW & MINI Models
From warning lights to total failure, we’ve seen it all. Some of the most frequent engine and transmission issues we diagnose and repair include:
-
Check engine light with no obvious symptoms
-
Oil leaks from valve cover, oil pan, or timing cover
-
Misfiring, stalling, or rough idle during acceleration or cold starts
-
Timing chain rattle on startup or at idle
-
Transmission slipping or harsh shifting between gears
-
Delayed engagement when shifting into drive or reverse
-
Overheating engine due to water pump or thermostat failure
-
Low transmission fluid pressure or burnt ATF smell
-
Torque converter shudder or transmission whining noises
-
Gear selector or DCT faults on MINI and M-series models
We’re especially familiar with BMW engines like the N20, N52, N54, N55, B58, and MINI’s 1.6L turbo and 2.0L engines, including common issues like timing chain guides, valve cover cracks, and ZF transmission.
How We Diagnose Your Engine + Transmission
Engines and transmissions are some of the most complex systems in your BMW or MINI, so when something feels off, a surface-level scan just won’t cut it. Whether you’re dealing with a misfire, transmission hesitation, or a check engine light that won’t go away, we use a combination of:
-
Visual inspections to check for leaks, damaged components, worn mounts, and fluid condition
-
BMW ISTA software to scan fault codes, read live data, and isolate transmission or drivetrain errors
-
Compression + leakdown tests to assess internal engine health and pinpoint mechanical failure
-
Fluid analysis to identify contamination, metal particles, or signs of overheating
-
Component-level testing for sensors, solenoids, vanos units, ignition systems, and valve timing
No matter the issue, we’ll get you answers fast. No guessing, no parts-slinging, no wasted money.

Why Engine & Transmission Repairs Matter in Georgia
Your BMW or MINI’s engine and transmission are precision-tuned machines, built for performance, but not immune to wear. Georgia’s heat, humidity, and stop-and-go traffic only accelerate that wear, especially if warning signs go unchecked.
Modern BMWs use advanced sensors and control modules to monitor everything from engine timing and fuel delivery to gear shifting and clutch response. But once a misfire, leak, or hard shift shows up, ignoring it can lead to catastrophic failure or even a full engine or transmission replacement.
We help drivers across Roswell, Kennesaw, Decatur, Marietta, Alpharetta, Sandy Springs, and beyond keep their performance machines running right, with BMW-trained diagnostics, OEM parts, and repairs you can count on.
