K03 Turbo 53039880049 06A145704H Turbocharger for Sharan 1.8T AWC Engine
Product Overview
High-Performance K03 Turbocharger for Sharan 1.8T & Seat Alhambra
- Factory Precision Fit: Built as a 100% direct bolt-on for the AWC engine platform. All oil, coolant, and mounting flanges are machined to exact OEM positions, ensuring a seamless installation without the need for manifold modification or custom pipework.
- Severe Heat Protection: The turbine housing is cast from high-nickel ductile iron. This premium material ensures the unit can handle the constant 900°C+ exhaust gases typical of the 1.8T engine without the housing cracking or warping—a major failure point in lower-quality aftermarket units.
- VSR Certified Balancing: Each core assembly is balanced on a high-speed Vibration Sorting Rig (VSR) at speeds exceeding 150,000 RPM. This process eliminates high-frequency resonance and protects the internal journal bearings, providing smooth, quiet operation and a significantly longer service life.
- Advanced Turbine Metallurgy: The turbine wheel is manufactured from K418 high-nickel alloy, maintaining its structural integrity at extreme rotational speeds. Paired with a precision-machined C355 aluminum compressor wheel, it delivers a sharp spool-up to restore your engine's original torque and responsiveness.
- Pre-Calibrated Wastegate: The internal wastegate and pneumatic actuator are pre-set to original factory boost levels right out of the box. No manual tuning or actuator adjustment is required to restore the original 150PS (110kW) power output, saving you time and cost in the shop.

Q1: Is this K03 turbo compatible with other 1.8T engines like the AGU or AUM?
No. While many 1.8T turbos look physically similar, the 53039880049 is clocked and calibrated specifically for the AWC engine's layout in the Sharan and Alhambra. Using it on other engine codes may cause misalignment with the oil lines or exhaust downpipe. Always verify your engine code is AWC before ordering.
Q2: I have part number 06A145713H on my car; is this the correct replacement?
Yes. Part numbers 06A145704H and 06A145713H are essentially the same part. Original brand often updates their part numbers or uses different codes for factory-new vs. remanufactured units, but this turbo is a 100% direct replacement for both.
Q3: Does the package include the necessary installation gaskets?
Yes, we include a complete gasket kit with every turbo, including the manifold gasket, oil drain gasket, and the necessary washers. We always recommend using these new gaskets to ensure a perfect, leak-free seal after installation.
Q4: What is the most critical step during the installation of this turbo?
Priming the unit with oil is vital. Before you connect the oil feed line, pour clean engine oil into the turbo’s oil inlet and spin the compressor wheel by hand. This ensures the journal bearings are lubricated the very second the engine fires up. We also strongly advise installing a new oil feed pipe to prevent old carbon debris from ruining your new turbocharger.
Q5: Do you provide worldwide shipping?What is the delivery timeframe?
We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
