Hi Funsters,
I previously posted earlier this year about an issue where the automatic gearbox suddenly failed to change up en-route on my Rimor 645 Sailor.
Mid-August I took my Rimor 645 to Mercedes servicing specialists who plugged it in - and found nothing wrong. No surprise, because the hydro-server, clutch and flywheel - the entire transmission components - had been replaced with new Mercedes parts at the 52000 mile point - so less that 13000 miles on the transmission since being renewed to the current mileage point of 64800 miles.
They spent hours checking all three ECUs (engine, transmission and dashboard), the looms, and each course of wiring to try to replicate the fault. Nothing found - all ECUs, looms and individual wiring in good condition. Not giving up, they persevered and eventually traced it back to a faulty fuel pressure valve.
They explained that this was stopping the auto from changing up the gears because the valve wasn't quite providing the amount nof fuel needed to change up. They replaced this one simple component and it's been faultless ever since.
Motto of the story is that tiny inexpensive things can cause bigger issues - but can be fixed easily
. All now perfect and for sale in the ads section. (The Rimor, not the faulty pressure valve).
