Black smoke and loss of power was an alarm bell that I could have done without, coming only a couple of weeks after my Freelander 1's Td4 engine flash upgrade. Of course, I feared the worst.
But a check under the bonnet showed that the original rubber intercooler hose had failed and the air compressed by the turbocharger was leaking through the split - it's a common occurrence on Td4 Freelander 1s, especially the top right-angled hose next to the battery. I could have gone for a set of standard replacements (about £30), but I decided to push the boat out.
Fitting was simple - I only needed a flat-blade screwdriver - but access was tricky. The hoses are still going strong 100,000 miles and eight years later.
