Guys, Some advice for a work friend please? Our company hired a van from a well know local supplier, to visit site. On the return journey (a total journey distance of 233 miles) the oil light came on. My friend (and it is my friend, not me) pulled over and checked the oil level. There was none in, so he brought some oil and topped it up. I don't know at this point how much oil he added (I'm trying to confirm now). I don't know if all dash board lights had now gone off (checking with friend). He then continued on his way. Shortly after the van started to smoke and he was forced to stop and call for roadside assistance. The van was then recovered as it was suspected that the turbo had failed. Prior to this recovery the oil level was checked again and was at the maximum. Whilst on site it was noted that the van smelt during tick over and prior to the warning light coming on, the van had lost some power. We are now looking at a bill in the region of 5K to replace the engine due to it being "overfilled with oil". They have sent us a photo showing the dipstick oil level a good 4 or 5 inches over the maximum level. The van was a 2008 VW caddy. What the hell can we do now? Where could the oil have gone between the initial refill and the photo supplied to us this week? Any and all advice appreciated, all questions welcomed.
