The engine and gearbox are where we truly excel. Our workshop in Musaffah is equipped with engine hoists, precision measuring tools, rebuild benches, and the latest diagnostic software covering all major manufacturers. When your car comes to us with an engine or gearbox problem, we follow a clear process every time.
First, we carry out a thorough engine diagnostic scan and visual inspection to identify all fault codes and physical signs of damage. Second, we call you with a detailed, honest assessment and a firm quote before any work begins. Third, our technicians carry out the repair using quality parts — OEM or equivalent — with no shortcuts. Finally, we road test the vehicle and carry out a post-repair scan to confirm the fault is fully resolved before we return your keys.
We cover all engine and gearbox services including engine repair and overhaul, engine oil leak repair, head gasket repair, timing belt and chain replacement, water pump replacement, radiator repair, coolant leak repair, engine mounting replacement, full gearbox repair and rebuild, automatic transmission service, transmission oil change, clutch replacement, CV joint replacement, and differential repair.
If your check engine light is on, your car is losing power, overheating, making unusual noises, or shifting badly — bring it to Muller Motors. We will find out exactly what is wrong and give you a clear path to fixing it.
