Hi, after reading this forum for years its my first time post so go easy :-)

100 miles after VW fitting a new DSG box just out of warranty i get a front assist unavailable dash light come on. After a bit of googling i am not sure if its a radar unit fault or it needs calibration. Could one of you good fellows cast your eye over the scan and offer some advice?. i am not sure on the component protection error as the car has only ever had work done by VW. If i need to replace the radar unit i would prefer to source and fit myself and return to VW just for calibration. i am not keen on giving vw any more money than i need too.

Hello,

The fault codes that are present in your Auto-Scan would indicate there is a concern with the J428-Adaptive cruise control unit, it's wiring/connections or it's components. You may want to have a visual inspection of the J428-Adaptive cruise control unit to be sure there are no obvious concerns.

Silly question, have you tried to clear all the fault codes? If so you maybe able to disconnect the battery for 30 minutes and then reconnect it, turn the ignition on and then try to clear all the fault codes.

Note : All three of these components are connected together with an Extended CAN-Bus and a Sensor fusion CAN-Bus connection, see the Official Factory Repair manuals and wiring diagrams for more information and where to check for possible wiring concerns as this is a little different than the normal CAN-Bus.
- J428 Adaptive cruise control unit
- J533 Data bus diagnosis interface
- R242 Front camera for driver assist systems


If the J428 is original to this vehicle, the "Component Protection" fault code can set if the J428 has lost communications with other vehicle controllers that provide the unique vehicle information that the J428 needs to make sure it has not been installed into a different vehicle.

You can install a new J428, it will need to go to the dealer for the proper calibration procedures.

Hope this helps,

drpeter

Thanks for your reply. Prior to posting the auto scan i tried to clear the fault codes but they come back straight away. i also disconnected the battery but it was nowhere close to 30 minutes. initial inspection of the radar unit does not show anything obvious. I don't think this car (september 2016 Mk7 UK Golf) has the R242 camera as its definitely not part of the rear view mirror housing. i also noticed today that the mode button to select Eco, normal or race no longer works which i assume is the last fault showing on the autoscan. Is this a coincidence or is there anyway it could possibly be related? i will try disconnecting the battery for a longer period and then start looking for a 5Q0 907 561 G cruise control unit. i read somewhere that disconnecting the J428 unit from the extended can bus or removing power to it would need the unit to be re-calibrated even if its not physically moved. would that be correct?
thanks,
J.

I do not recall any mention of any calibrations of the J428 if the battery was disconnected. I do see the repair manual states the following:

Under the following conditions the Distance Regulation Control Module - J428- must be calibrated:
♦ Distance Regulation Control Module - J428- was removed and installed or replaced.
♦ The lock carrier service position was performed
♦ The lock carrier was removed and installed.
♦ The lock carrier was replaced
♦ The rear axle toe were replaced

So I think it is safe to disconnect the battery for a while. Also if there is no R242 Camera, the CAN-Bus appears to be the same.

I would try dealer first to try and get this one removed :

Code:
5360256 - Component Protection 
          U1101 00 [009] - Active
          [FAULT_THP_EC_COUNTER]
          Confirmed - Tested Since Memory Clear
             Freeze Frame:
                    Fault Status: 00000001
                    Fault Priority: 2

                    Date: 2019.11.03
                    Time: 16:31:12

                    Control Module temperature: 19 °C
                    Voltage terminal 15: 11.8 V
                    Velocity_vehicle_reference: 0.00 m/s
                    Longitudinal_acceleration_vehicle_reference: 0.00 m/s²
                    Status_ACC_System: ACC_irreversible error

That will cause the radar to disconnect and cause a front assist unavailable error. New DSG mecha will require CP removal and most likely your dealer just forgot to do it ACC module. It is very hard for me to believe that the radar would be broken all of a sudden.

It’s hard for me to believe as well. I emailed the service guy at the dealer soon after the light came on. They said they couldn’t see how it was related but were happy to investigate it for £85. With the drive mode button not working, the ACC and the component protection fault happening 100 miles after the gearbox being replaced does seem to be a bit odd... then again having the car serviced in warranty and then 300 miles later (4weeks out of warranty) it needs a new gearbox (at 20k miles) says it all. If it wasn’t for bad luck I wouldn’t have any ;-).

If gearbox CP got removed without renewing other CP stuff then this is exactly how it happens.

There are few tpis about this for techs that do one and only one thing. Also FeC-s also tend to dissapear when renewing CP.

hmm.........Yes, it's just indicative - but the difference between the mileage values on the autoscan date of production and the mileage value on the CP error suggests that this car doesn't travel far (i.e. 37 kms in 2 x days).

Plus the CP error in the hex13 module doesn't have a matching twin DTC in the CP master module (i.e. hex19) - which is real odd (I've seen this happen in hacked MIB units).

Not sure what it all means, but proper CP interrogation is only meant to happen after ignition switch-on (as I understand) and given that the hex13 module hasn't been changed it should have easily passed the routine challenge/response identity-check process on 3rd November 2019.

And, even if the module had an unfortunately timed hiccup when OP turned the ignition key on 3rd November 2019, the module should have re-established its legitimacy to be on the CAN network in a subsequent ignition cycle.

So, given the odd nature of these circumstances and notwithstanding the requirement for FAZIT connection in dealing with CP errors, (IMO) it's worth attempting to delete this DTC with VCDS (or try DrPeter's suggestion). It's an easy try and there is no downside and there is very little "downtime" -pun intended ;).

Good thinking again Don but unfortunately OP already tried clearing DTCs and wrote that they come back immediately.

DSG mecha and TCM seem to have more mastery touch to the cars systems as for example you can clear CAN installation info from DSG module.

So if ACC CP is matched somehow to both engine ECM and transmission TCM then naturally they’re not matching now and CP is triggered.

Thanks all for the information and advise. Went back to the dealer who cleared the faults and “reset basic settings”. Not easy getting information from someone in service who doesn’t know an ass from an elbow. There was no charge and all is working again....for now.
Cheers,
J.
