Trans Failsafe Prog

[royemaun]

Hi all,

I know there are lot of threads, sorry to post again ;P.
Wondering if anyone has any advise on my problem. I have a 2001 X5, 4.4i. two weeks ago, the 'Trans Failsafe Prog' message always appears in my cluster. Clearing it from the scanner did the trick but only for the meantime. i found out that the boot going to the throttle body is a bit loose so tightened it and the X runs smoother and strong. However, after few days the message is there again. this time it appears when i'm on a downshift especially 2nd or 1st gear or on a complete stop. cleared the message by turning off and on ignition but sometimes it doesn't even engage to 1st gear then 'Trans Failsafe Prog' message appear. prior to this, few months ago the cluster always displays this message then sent it to the dealer for a software update and the message disappeared. but the last few days it's driving me crazy... I have the GT1 but is off to the seller for replacement, never had a chance to use it for diagnosis. my other obd scanner pulled a code referring to Camshaft position A but it showed only once. work done so far to trace this issue was cleaned the MAF and throttle body with a brake cleaner. replaced one camshaft sensor (passenger side of the engine)....

thanks for any help in advance.

cheers,
