Non start/non crank with flashing "F" on dash.(though aparrantly it did fire up briefly last night) Faultcodes as follows using Launch...


Engine management.

ECU identification data seems good!

P0136 (O2 sensor-intermittant)

P1615 (Incorect vehicle ID from BCM)

P1616 (Incorrect vehicle ID from instrument cluser)


Transmission ECU

ECU identification data seems scrambled. VIN numbers etc all seem replaced with "***?**"

However codes follow..

P1722-008 (selector lever agreement-Not present)

P1723-008 (Selector lever redundent data agreement-not present)

U2107-C (CAN No coms with IPC (istruments) or BCM-Not present)

P1607-000 (Controller replace-Present)

P0725-004 (Engine speed sensor CAN bus Malf-Present)

P1895-004 (Engine torque sensor CAN bus Malf-present)

U2100-c (CAN bus Malf-not present)

U2108-C (CAN bus no coms with ABS, Reprogram/replace controller-present)

U2105-C (CAN no coms ECU- present)

A scan of instrument cluster, Immobiliser and ABS revealed no stored faults.

Autodata does not appear to have any additional info on the transmission fault codes and although a google search suggests that although the "Flashing F" problem is not uncommon, none of the examples I have found seem to correspond with this list of fault codes.

In addition, the hydralic fluid resevoir on the top of the gearbox contains a nasty dark brown fluid with small bits floating in it! Whether this is related to this particular problem or not (Or is just another nasty for the future) I cannot really say.

Now the question is...

Is this likly to be a scrambled ECU requiring dealer level reprogramming/replacement. Mechanical issues within the gearbox, or a loose wire somewhere??

Or a combination thereof...

Any thoughts gratefully received..
