The fault
How you spot it
The EGR cooler can crack from the thermal load, and coolant gets into the intake through the crack. The fault is reported at around 120 000 kilometres.
The most telling sign is black foam in the expansion tank: the recirculated exhaust gas sooties up the coolant. With it comes the coolant going down while there is no leak from outside, white smoke from the exhaust, and the engine tending to run hot.
In severe cases the fluid getting into the intake causes a hydraulic lock, and engine damage follows from that. The fluid is not compressible, so once it is in the cylinder it is the connecting rod that has to give. The repair is replacement of the cooler, and it is not worth putting it off.

Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
