Zeekr 008 Diesel Losing Power Under Load? EGR and DPF Checks First

If your Zeekr 008 (the diesel variant, if you have one – most are electric) is losing power when you put your foot down and blows black smoke, you're looking at a fuel/air/exhaust restriction. The usual culprits are the EGR system and the DPF. Let's walk through this like I would with a car in my shop.

Likely Causes

• Clogged EGR valve or cooler – Exhaust gas recirculation that sticks open or blocks can choke the engine of fresh air, causing black smoke and power loss. On most diesel engines, the EGR valve is a separate part from the cooler and can often be cleaned or replaced individually.
• Partially blocked DPF – A diesel particulate filter that's filling with soot increases backpressure. The engine can't breathe out, so it loses power under load and may smoke. In many cases, the DPF is a separate unit from the catalytic converter, so a forced regeneration or professional cleaning might fix it without replacing the whole exhaust section.
• Faulty sensors – The MAF (mass air flow), MAP (manifold absolute pressure), boost pressure sensor, or EGR position sensor can send wrong readings, which messes up the air/fuel mix. These are usually individually replaceable parts.
• Injector issues – Less common, but a worn or dripping injector can cause poor atomization and black smoke. Check these after ruling out EGR and DPF.

What to Check First

• Use an OBD-II scanner for codes like P0401 (EGR flow) or P2463 (DPF restriction). That gives you a solid starting point.
• Inspect the EGR valve for carbon buildup while it's off – if it's sticking, cleaning or swapping it alone often does the trick. On many models, the valve and cooler are separate, so you don't need to replace the whole assembly unless both are damaged.
• Check the DPF pressure sensor (differential pressure) readings. A high reading at idle or over a certain threshold suggests a clogged filter. Some shops can do a forced regeneration, which might clear it without any parts.
• Look for boost leaks – cracked hoses or loose clamps between the turbo and intake can cause black smoke and power loss too.

Is It Safe to Keep Driving?

In my honest opinion, it's not great to keep driving like this for long. A heavily clogged DPF can overheat and damage the turbo or injectors, and an EGR stuck open can make the engine run rough and hot. You can drive gently to a repair shop – avoid hard acceleration, long hills, or towing – but I'd get it looked at soon. Since the 008 is usually an EV, double-check that your model actually has a diesel engine and the same diagnostic steps apply; if so, this is a well-trodden path for most modern diesels.
