Thank you

Thank you to every one that has contributed to this thread!!

Just picked the truck up from the mechanic and they have put a new water pump in plus re flushed the cooling system and installed a highflow thermostat !!! All at cost price thank god, I must say they have been good to me in that respect ....

I was also reading about partially blocked cat converters causing overheating! Not educated on this at all but figured it might be worth taking the truck in to have the exhaust checked before the next big trip in 2 weeks (more for piece of mind, would rather that than breaking down 8hours from home )

Hopefully we have resolved the problem and have a good trip 😊 will post again with the result 😉

Hopefully the issue is resolved.

A clogged Cat would probably cause above normal exhaust back pressure. Can you monitor that?

plugged cat would cause it to run poorly.

Yes. Lower power and higher heat. Just looking for a way to diagnose a plugged cat without having to cut into the exhaust.

I would be surprised if it has a cat. But a freed up exhaust certainly won't hurt anything! Be that as it may, my bet is that the water pump was the problem.

I agree. However, I had one on this e99. I can't find a pattern as to why some had them and others didn't.

I have no idea what the laws are in Australia, so they may very well have cats. Monitor the EBP/MAP together to get a clue. They should be very close together with normal driving.

Thank you for the info. That is what I thought but was't certain.
