New Mercedes GLA 180 CDI Turbo – Ref. A6070900400

Identifying the correct turbo reference for your Mercedes GLA

Before placing an order, it is essential to check the reference number stamped on the original turbo fitted to your Mercedes GLA, as several turbochargers may have been used on this model depending on the engine and year of manufacture. This new turbo is compatible with reference A6070900400, as well as a range of equivalent references from manufacturer and supplier catalogues, which can be viewed directly in the technical sheet on this page. Take the time to compare the number engraved on your old turbo before confirming your purchase, to ensure perfect compatibility with your vehicle.

Compatibility with the GLA 180 CDI diesel engine

This new turbo is designed for the Mercedes GLA fitted with the 180 CDI engine, a 1.5-litre diesel unit (1461 cm³) known under engine code K9K 666. This engine, shared with other models in the group, is noted for its fuel efficiency and reliability; however, the turbocharger remains a sensitive component subject to significant thermal and mechanical stress, particularly in urban use with frequent stop-start cycles.

Straightforward sale: nothing to return

This turbo is sold new as a straightforward sale: you receive a single delivery and have nothing to return — no collection, no deposit, no old unit to send back. The turbo comes with a 12-month parts warranty, subject to fitting by a qualified professional. Payment for your order can be spread over up to 10 instalments to make your purchase easier.

Common causes of turbo failure on the GLA K9K engine

On this 1.5 diesel engine, the majority of turbo failures stem from a lubrication fault: old oil, missed oil changes, or a clogged oil filter. A blocked air filter or a cracked intercooler can also cause abnormal boost pressure and accelerate wear on the internal bearings. Driving too aggressively from a cold start, before the oil has reached its operating temperature, also weakens the turbocharger over time.

• Check the condition and cleanliness of the intake and boost hoses
• Inspect the oil circuit (feed and return lines) before fitting
• Clean or replace the air filter if necessary
• Check for any obstruction at the air intake

Tips for running in the new turbo

During installation, it is recommended to prime the oil circuit before the first start, to avoid the turbocharger running dry. Let the engine idle for a few minutes after fitting, without putting the turbo under load by accelerating, to allow oil pressure to stabilise throughout the circuit.
