I have a weird one.
Toyota rav 4 iii diesel turbo 2005-2010 (133)
I have been trying to fix the problems of my rav4 for a couple of months.
General info. The car was bought second hand, the ecu is manipulated. It had gone through a dpf delete, and mileage was for sure changed, all of this i found out after purchase.
The car now runs a new dpf and a new turbo, after these changes it drove well for a couple of months. But had very little power under 2,000 .
then came a limp mode (without a code) coming again and again when throttle is open. Looks like turbo overboost. Because of the low power on low revs and other issues i changed the egr valve (no help)
also changed all filters.
the car was at more then one official toyota garages in germany but as they could not get a diagnosis (no code) they all gave up and said i should get rid of it. On top of it all the cruse works occasionally and sometimes won’t switch on at all.
last and most important detail-
i have recently noticed that the car drives completely well when it rains and the road is wet. It has complete power, doesnt go into limp, and cruse works. Just perfectly functional. This brings me to the theory that a bad e connection is the cause of it all.
my question, which wiring area or part in the car is low enough to get wet when driving and would cause the cruse to not work + engine to not run currectly.
Any help is very appreciated.
