Did you pressure clean under the vehicle coming off the island or go through some water on the beach? I had all sorts of tranny faults come up after giving my girl a really good pressure clean under her skirt 😀😀😀 Dry weather should be your saviour. Give it a day or 3.
Otherwise, my money is on your battery. It's amazing the difference a new battery makes. Matti
If it's the original battery then it wont have much life left. However dropping voltage to cause gearbox and other faults whilst driving then being OK later wont be caused by a battery failing to keep its charge but could be due to an internal break in the battery. Another possibility is an intermittent short circuit in wiring somewhere causing excessive current draw which may take some finding although as circuits are fused the cable would have to be heavy, such as the starter cable. Monitoring the voltage whilst driving and especially during one of its episodes might provide a useful clue.
I started the car myself with no one else to watch but by the time I got around to the multimeter the car was up in the 13's already.
i was driving around the island for a few days which includes plenty of water however the fault first happened just after I jump started the car which was when I woke up in the morning, as in I went to move the car and there was a distinct lack of power. I turned it off and the car performed normally again.
after leaving the island I power washed under the car but the next drop in power didnt happen until 4+hours of driving later.
I had the fridge still still plugged in as well as an arc pack charging in the boot so when the next default happened I wondered weather this was causing the issues so I unplugged both for the remainder of the trip home but had it once more after that.
I will I'll give it a few days and see how she goes, and look for anyone selling an iidtool too!
Ill make sure to teport back!
Hi,
It could possibly be a grounding issue with a sensor/module. I went through intermittent faults with my car awhile ago, difference being my car was setting itself to limp mode.
It took Landrover 3 attempts of finding the issue. They changed main fuses, a sensor in the steering wheel and who knows what else prior to finding the ground fault.
Each time it came back from LR, and i took the car over some rough road or hit a speed bump hard (to test it), the car threw the fault each time.
I forget which sensor it was, i do know it was near the rear suspension. Since then the car has been great.
Maybe you could pay someone with a iid tool to add an extra VIN to their iid tool if you want to save a few dollars.
Cheers
