| Engine and gear box in security mode |
|
Hello everyone,
I have a problem with my Disco 3 2,7 TDV6 from 2005.
I was driving on the highway since 800 km without any problem when suddenly the car went in security mode with many warning lights ON on the dashboard (see pics). I switched OFF ignition waited for a couple of seconds and started again. All OK till the next event… I have linked the car to the computer and I have a code U2023. I have opened the gearbox control module to check for moisture/water ingress and all was ok, no signs of corrosion or bad contact. I have flushed the automatic gearbox to be sure to have the correct level of oil. All ok.
I have been driving my car for two months without any problem and yesterday the problem reappeared.
Temperature has no influence as it happens on cold or warm engine/gearbox.
The EGR valves have been removed and I have permanently the check engine light ON with two errors codes (P0405 and P140A). From what I have noticed, these codes have no influence on the problem. The problem arises when the code U2023 appears (randomly). Can anyone help and tell me what to check and maybe how to solve the problem. I will add some pictures to illustrate the text. Thank you very much for your returns!
