• Boost low, high or unstable under load
• Loss of power with black smoke

🛠️ Service Notes

• Turbocharger 3801158 is also a wastegate unit for 2 TAD applications at 15.921 kg and 3801163 is 15.422 kg, so under a kilogram covers all three and the designation decides
• Check the oil feed, air filter and charge air pipework before the new unit is run
