Do you have factory ISTA and XENTRY diagnostic systems?

Yes. We run genuine BMW ISTA and Mercedes-Benz XENTRY for full coding, programming, VANOS adaptation, AdBlue calibration and AIRMATIC strut coding.

Can you fix the timing chain on N20, N55 and S55 BMW engines?

Yes. Timing chain, guide and tensioner replacement on N20, N26, N55 and S55 BMW engines is a routine job for us — performed with OEM parts and post-repair adaptation through ISTA.

Do you service AIRMATIC and ABC suspension on Mercedes?

Yes. AIRMATIC strut replacement, compressor service, ABC pulsation damper and pump rebuilds, and full XENTRY-driven calibration are all performed in-house.

Where are you compared to the BMW and Mercedes dealers in Dallas?

We are in Plano, north of central Dallas, equally convenient to Highland Park, Frisco, Allen, McKinney and Southlake — typically 15-25 minutes from any of those areas.

Will independent service void my factory or CPO warranty?

No — under the Magnuson-Moss Warranty Act, qualified independent service performed with OEM-equivalent parts and documented to manufacturer specification generally does not void factory or certified pre-owned warranties.

BMW & Mercedes Repair Dallas TX | Motek EuroWerkz

Motek EuroWerkz is an independent BMW and Mercedes-Benz specialist in Plano, Texas, serving Dallas, Frisco, Highland Park, Southlake and the DFW Metroplex. We run factory ISTA and XENTRY diagnostics on every job and install OEM parts as standard.

Two German Brands, One Specialist Shop

If you own a BMW or a Mercedes in North Texas, you already know the drill: the dealer wants three weeks for an appointment, the chain shops are happy to throw parts at the car until something works, and the warning lights you cleared last spring keep coming back. Motek EuroWerkz takes a different approach. We run genuine BMW ISTA and Mercedes XENTRY on every car that comes through the door, we install OEM parts as the default, and we explain the diagnosis in plain English before we recommend the repair.

Our facility in Plano is a short drive for owners across Dallas, Highland Park, Frisco, Allen, McKinney and Southlake — and we offer pickup and delivery throughout the Metroplex for clients who would rather not sit in traffic on the DNT. Whether the car is a daily-driver X5, an enthusiast-owned M3, a chauffeur-driven S-Class or a recently retired AMG GT, the shop standard is the same.

Common Repairs DFW Owners See

Coolant & Cooling System

Plastic coolant components on both German brands have a finite lifespan, especially in Texas summers. We replace expansion tanks, water pumps, electric thermostats and radiators with revised OEM parts that handle the heat.

Oil Leaks

BMW oil filter housing gaskets, valve cover gaskets and oil pan gaskets — and Mercedes valve cover and rear main leaks — are routine for us. Done correctly the first time, with the seals that actually hold.

Suspension & AIRMATIC

AIRMATIC and Adaptive M Suspension struts, control arms, ball joints and bushings — coded and calibrated through XENTRY or ISTA so the ride height and dampers actually work as designed.

Brake Systems

BMW M Carbon Ceramic, Mercedes-AMG ceramic, and the standard composite/iron rotor packages — pads, sensors, fluid flush and proper bedding-in.

Coding & Retrofits

iDrive enable, video-in-motion (where legal), Apple CarPlay activation, headlight coding, comfort feature retrofits — done through ISTA/E-SYS or XENTRY, not eBay tools.

Pre-Purchase Inspection

Multi-point PPI for buyers in Dallas, Houston, Austin and out of state. Lift inspection, full ECU pull, leakdown where applicable and a written report.
