Evening guys and gals,
So the reached out and I have now had two interesting and indeed frustrating sessions with this vehicle, todays was 5 hours!
In the first session I completed the following:
- 3Q0907530L/C gateway in place. Re-coded correctly as additional modules were added to installation list which the vehicle does not have. Recoded vehicle also. Once error free I attempted to upload parameters with no luck. Replace Module and FES = Control module not valid.
- 5Q0907530T gateway in place, removed, parameter upload no go. Replace Module and FES = Control Module not valid.
- 3Q0907530L/C reinstalled, Drive Mode Issues remain, no errors on vehicle.
In the second session:
- 3Q0907530L/C installed, tested additional upload of parameter sets, no go.
- 5Q0907530T Gateway reinstalled and then flashed to AJ, Removed, parameter upload no go. Replace Module and FES = Control Module not valid.
- 5Q0907530T (now AJ) Gateway flashed to AM, Removed, parameter upload no go. Replace Module and FES = Control Module not valid.
- 5Q0907530T (now AM) Gateway flashed to Q, Removed, parameter upload no go. Replace Module and FES = Control Module not valid. Range Error Returned. Only available Q firmware was Audi so am guessing this was always going to fail but wanted to see the Range Error as its something I have not seen before and I have retrofit way too many to count / remember.
- 5Q0907530T (now Q) Gateway flashed to T, Removed, parameter upload no go. Replace Module and FES = Control Module not valid.
- 3Q0907530L/C installed in order to return vehicle to error free state, ECO, Normal and Individual Drive Modes.
Official parameterisation and FES is not possible with this vehicle / VIN. Tested all available manual parameter sets with interesting results as while able to always restore the basic drive modes of ECO, Normal and Individual whenever I managed to restore Race it would only be in conjunction with Individual and switching via the mode button was not possible. Also on ignition cycle any and all available drive modes would disappear. Disconnecting and reconnecting power to the Gateway would bring drive mode display back again but not allow switching. A further ignition cycle would then cause them to disappear again until re-uploading. Even a hard reset on the Gateway would not make them pop again.
Conclusion, unless anyone else can shed light on this, a used gateway from a golf R needs to be sourced and installed in to this vehicle with parameters intact or another golf R needs to host a gateway which can be parameterised / FES officially and then transferred over to the problem vehicle, example:
- Golf R with factory fitted T found.
- Replace factory T with another T module.
- Code, parameterise, FES etc.
- Remove and install in to problem vehicle.
Any ideas / thoughts would be welcome as I am not sure what else would be possible short of "spoofing" another R but this comes with its own set of complications...
