Independent service for BMW 3 Series (F30/G20) owners at the Ümraniye Kadosan Auto Industrial Estate. Computerized fault diagnosis on B48/N20 petrol and B47/N47 diesel engines, oil-leak and EGR repair, guaranteed workmanship, and the assurance of original or quality equivalent parts.
Ulu Otomotiv is an independent service in the Ümraniye Kadosan Auto Industrial Estate, specializing in the BMW 3 Series; we service to factory standards and use original or quality equivalent parts. We are highly experienced with all F30 and G20 chassis, as well as the B48 and older N20 petrol and the B47 and N47 diesel engines. Every vehicle first goes through a computerized fault diagnosis with an ISTA/diagnostic device, and we interpret fault codes based on measured data rather than guesswork. The valve cover and oil pan leaks common on this model, plastic cooling-system component cracks, EGR fouling, and timing chain inspection are our areas of expertise. We discuss every procedure with you in advance, never resort to unnecessary parts replacement, and cover both the installed parts and the labor under warranty. Our goal is to preserve the driving pleasure and reliability of your 3 Series for many years.
If you notice any of the symptoms below, a prompt expert inspection is important.
Dark oil drops under the vehicle or a burnt-oil smell from the engine is the first sign of the valve cover gasket or oil pan leak typical on the F30/G20; it should not be neglected.
A metallic rattle from the front of the engine, especially on the first cold start in the morning, can indicate that timing chain tension has dropped; it calls for a chain inspection.
A dropping expansion tank level, a fluctuating temperature gauge, or a coolant smell stems from leaks tied to this model's chronic plastic-component cracking.
On B47/N47 engines, the EGR clogs with carbon in city driving; misfiring, power loss, and the engine warning light appear, requiring diagnosis and cleaning.
Jerky or delayed shifts on the ZF automatic transmission indicate that it is time for an oil and filter service or that a mechatronic check is needed.
A clunk over bumps, noise in corners, or a shudder in the steering signals control arm bushing, ball joint, and sway bar wear on the F30/G20.

“I came from Ataşehir with a burnt-oil smell from the engine. They checked it with ISTA and clearly showed me the problem was the valve cover gasket. They didn't suggest any unnecessary parts, just replaced the leaking gasket. The smell and the leak are completely gone, and the labor is under warranty. They work transparently.”
“I live in Çekmeköy and my diesel had power loss and a warning light. They diagnosed EGR carbon buildup and cleaned it, and didn't suggest anything illegal like deleting it. The car is back to its old power, and they explained every step beforehand. I recommend them with complete peace of mind.”
“I brought my car from Maltepe because it kept losing coolant. They found the cracked plastic water pump and thermostat and replaced them with quality equivalent parts. The overheating problem is gone, and they informed me about the price and timing up front. An honest team that knows its work.”
