The fault
How you spot it
The length of the intake manifold is adjustable: a switching linkage moves the flaps, and that linkage is made of plastic. An oil leak appearing at the intake manifold turns the plastic porous, and the linkage breaks.
With a broken linkage the flaps do not move, which means the intake manifold stays in one position. The symptom is a noticeable loss of power and a fault lamp coming on.
The cause is therefore not the age of the linkage but the oil: until the leak is stopped, things end up in the same place again after a replacement. Repair kits are available on the market, but they do not deal with the leak that causes it.

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.
