N20, N55 and B58 leak repair
Valve cover and filter housing leaks are the classic BMW case. We fix the source with genuine gaskets and check the PCV, which is often the real cause.

Why us
Marque-specific experience
Its engines run hotter and to tighter tolerances, so delaying oil or cooling work costs many times the service itself.
BMW faults are predictable if you know them: timing chains, valve cover leaks, electric water pumps and Valvetronic issues. We handle these daily and find the cause quickly instead of swapping parts.
We use BMW-specific diagnostic and coding tools to read and code every module after repair, and service ZF gearboxes including fluid, mechatronics and adaptation resets.
BMW service in Riyadh starts with the engine family: N20, N55, B48 and B58 each have their own weak points and procedures. We identify it from the VIN and build the plan on it.
Daily BMW complaints we handle: burnt oil smell after parking, low coolant messages, vibration under acceleration and delayed shifts. Inspect, report, then repair — always in that order.
Services
Specialist work
From engine leaks to module coding, this is the BMW work that comes through the workshop daily.
ZF 8HP transmission service
The ZF box is not really 'sealed for life'. A timely fluid and filter change extends its life, especially in Riyadh heat and city driving.
Cooling system and electric pump
The electric water pump and thermostat have a defined service life; sudden failure can overheat and damage the head. We check both at every service.
Coding and feature activation
We code modules after replacement, restore factory settings and fix CAN network faults that trigger several error messages at once.

Equipment
How we diagnose this marque
Marque-specific platforms and workshop equipment work together to isolate the cause.
01
Marque-level diagnostic tools
Every European marque has its own diagnostic platform that reaches all modules, not just the engine ECU. We read stored and live faults with their conditions, compare them against factory values for that exact model, and keep a copy of the report before and after the work so you always have a clear reference.
02
Lifts and wheel alignment equipment
Checking suspension means lifting the car and loading each joint individually, not shaking a wheel. After any suspension or steering work we align on measuring equipment and hand over the before-and-after readings, because one angle out of range is enough to eat a tyre and change high-speed stability.
03
Temperature-controlled gearbox filling
A modern gearbox does not accept estimated filling. The correct level is set at a specific fluid temperature with a calculated quantity; too much or too little later shows as overheating, low pressure or a shift jolt. We change the filter and gasket, clean the magnets in the same operation, then reset adaptations and road-test the car.
04
Refrigerant recovery, weighing and leak testing
We first recover and weigh the existing charge to learn how much the car actually lost, since a shortfall always means a leak. We trace it at joints, condenser, compressor seal and evaporator; after the repair we vacuum out moisture and charge the exact weight and oil specification. These steps are the difference between cooling that survives a Riyadh summer and a refill that fades in weeks.
05
Measured body and structural repair
A European body is engineered to absorb impact energy in a calculated way, so every accident repair starts by measuring the body points against factory data before any pulling. Partial respray uses a colour match verified with a test card inside a spray booth, and once finished we set the alignment and recalibrate cameras and radar if they were affected.
06
Organised parts store and trusted sources
We stock fast-moving parts for the marques we serve so your car does not wait days for a filter or a gasket. Parts are either genuine or from the original equipment manufacturers themselves, with the type stated in the report before work starts; anything not available locally is ordered with a stated lead time before you decide.
Technicians
Who works on your car?
Technical decisions based on the VIN, measurement and documentation, not guesswork.
01
A technician per marque
Your car goes to a technician used to that specific marque, not to whoever is free.
02
Work starts from the VIN
The VIN fixes the generation and the correct fluid and part spec, preventing look-alike part mistakes.
03
Photo report before work
You see photos and scan readings before approving; nothing outside the approved list is carried out.
04
Genuine or spec-matched parts
The part type is stated in the report, and you choose between genuine and approved equivalent.
05
Post-repair handover check
After any repair we rescan and road-test the car before handover.
06
Documented follow-up after handover
The handover records completed work and follow-up items, making later reviews easier against the vehicle history.
FAQ
FAQ
When does the timing chain need replacing?+
When you hear a cold-start rattle or a camshaft timing code appears. We verify by scan and inspection before recommending work.
Do you change 'lifetime' gearbox fluid?+
We recommend periodic changes based on use and Riyadh heat — the fluid is what protects the gearbox internally.
Do you provide scheduled BMW service?+
Yes, using the correct fluid, filters and interval for the model and Riyadh conditions.
Do you diagnose BMW before repair?+
We begin with module scanning and physical measurement, then explain the result before ordering parts or starting work.
