I think it was more to do with the fact that the old style tray covered everything and when the oil leaked from the timing chain case or front seal it soaked into the tray which appears to be made of a fibre board. Unfortunately where the oil collected is about 20 mms from the exhaust which gets very hot and has in some cases I understand caused a fire. I removed mine when the recall came as we were going away with the caravan and things do get hotter towing, the tray had a stain but was by no means wet with oil and had been fine for three years although not sure when the oil leak started.
Interesting to see your photo of the dpf Victor, where exactly is it in the system?
