Hi iam looking at buying a 02 tdci it's done 78000 miles, but it had gearbox oil On the bottom of the gearbox which we belive is coming from the driveshaft, and it had oil underneath the intercooler pipes mainly the one on the right.. Would you avoid this car or are these common faults which can easily be fixed.. The lad who is selling said he would fix the gearbox oil because he's a macanic but said its usual to get the oil underneath the intercooler pipes.. Any help would be great.. Thanks and it's a 1.8
