Why does the turbo fail on the Mercedes CLS 350 BlueTEC/d?
On the V6 3.0 Diesel OM642LS fitted to the Mercedes CLS 350 BlueTEC/d and its 4MATIC variant, the variable-geometry turbo is put under considerable strain during sustained acceleration and long motorway runs at a steady speed — both typical of how this saloon is used. Insufficient lubrication, degraded or non-approved engine oil, a clogged air filter or a faulty intercooler are the most common causes of premature wear to the turbine and bearings. Driving habits that involve sharp bursts of high revs without allowing the turbo to warm up or cool down before switching off the engine also accelerate mechanical fatigue throughout the assembly.
New turbo compatible with reference 826830-5004S for this Mercedes CLS
This new turbo is compatible with reference 826830-5004S and fits the CLS 350 BlueTEC/d and CLS 350 BlueTEC/d 4MATIC, equipped with the 3.0 V6 Diesel engine (engine codes OM642LS, OM 642.852, OM 642.853, OM 642.858). Before placing an order, we recommend checking the exact reference marked on the old turbo once removed, as production revisions may coexist within the same model.
Warranty and delivery of the new turbo for the CLS
This new turbo is sold outright: there is no old unit to return and no core return required. Delivery is made in a single shipment. The part carries a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments.
Fitting advice for the CLS 350 BlueTEC turbo
Before installation on the V6 OM642LS, check the oil circuit (feed and return lines), the condition of the air hoses and the cleanliness of the air intake upstream of the turbo. Prime the turbo with oil before the first start-up to ensure immediate lubrication of the bearings. Also check the intercooler and replace the air filter if necessary — both are essential steps to protect the longevity of the new turbo on this engine.
- Check the oil circuit and its cleanliness before fitting
- Inspect the hoses and air intake
- Prime with oil before starting the engine
- Observe oil change intervals using the correct grade of oil
