Engine warning light and loss of power? Could it be the EGR

Signs of Stuck EGR
If you leave it, the engine chokes and drags down the DPF and turbo. Timely repair is cheap.
Codes P0401/P0402/P0404. The car enters safe mode.
A stuck EGR valve introduces too much exhaust gas and chokes the engine.
More diesel, smoke, and carbon build-up that ends up saturating the DPF.
Why with Zamule Cars
We check if the EGR can be cleaned or needs replacement, and if the problem comes from elsewhere.
Disassembly, thorough cleaning or original part, and adaptation reprogramming.
OEM -10%EGR + decarbonization + DPF check. We attack the cause, not the symptom.

Faults common of the EGR
What we see most often. A dirty EGR affects the DPF, turbo, and injectors.
It's emitting too much exhaust, choking the engine: smoke, jerking, and power loss.
NOx emissions increase and the anti-pollution light comes on.
The valve is not moving. EGR circuit code (P0489/P0490).
EGR soot clogs the intake manifold. It needs cleaning.
Coolant mixes with gases. Loss of fluid and white smoke.
Excess carbon build-up ends up cementing the DPF.
