today I am getting continuous TPMS faults which come back after dtc erase even after performing angle sensor calibration. Could this be due to the failing arm bushes above? which would give angle sensor faults too?? or do you think angle sensor needs replacing??
angle sensor error?? can someone explain??

No, a failing bushing should not throw a steering angle sensor DTC. I know you have done many many retrofits in your car (very interesting reads, thank you) so I would first check wiring. Maybe a connector got loose somewhere.

That would be a nightmare hope it is the angle sensor failing or the bush arm having failed causing considerable play.
After some thinking, will replace bush arm guides first before changing the squib or before checking the angle sensor to brake electronics connectors.
Thanks for your reply.
Just in case never did the following will also give it a try.
Vehicle Inclination Sensor (G384)
Necessary after Replacing the Parking Brake Control Module (J540)
Prerequisites:
Parking brake control module properly installed (bolted down).
System voltage at least 12.0 V.
Car parked on a level surface.
Do NOT move/rock car while performing basic setting.
Perform Function Test (BS 010) prior to Initiation G384 (BS 020)
Function Test
Prerequisites:
Cycle the Parking Brake ON, then OFF first.
[Select] [53 - Parking Brake] [Basic Settings - 04]
Group 010 [Go!]
The brake pads are now opening and closing 3 times.
Wait 30 seconds after the the brakes stop making noise. [Done, Go Back] [Close Controller, Go Back - 06]
[Select] [53 - Parking Brake] [Basic Settings - 04]
Group 020 [Go!]
Activate the Basic Setting. [ON/OFF/Next]
The status of the Vehicle Inclination Sensor (G384) is now being displayed. [Done, Go Back]

Did the above successfully but no joy.
Also Removed all TPMS codings (from 3 control units ) to disable TPMS and now I receive a stabilization issue message on instrument cluster display. Any ideas guys?

seems to me that correct procedure is
1. install the new arms and test
2. If dtc remains change angle sensor/squib and check connectors.
will post more info after arms are installed.

Will do so. Should I keep esp disengaged or does it disengage by itself???
Nobody in this forum had a similar issue?? Probably not something usual. There are more important issues I guess with the Q5.
UPDATE:
Disabling ESP does not stop the stability issue / error message.
I would assume, and worry, that if you get an ESP error message that the ESP system is not actually functioning so do not expect it to work properly in any situation where it might be needed.

Thanks. I concur.
Note I only get the stability error on instrument cluster once during my drive then it turns off whereas with TPMS, the lights(and one on the display of IC so actually 2) were always on. So will keep coding with TPMS off until parts arrive and installed. Because there was a noise behind the steering wheel in the past' it could be a connector to the slipring or the slip ring broken (or the steering column). That is why I purchase the slipring 6 months ago. However will first do the arms just to be sure.

I think I have a solution.
Checks I did.
1. Check abs sensors.ABS controller measuring block 1. If all abs sensors show correctly the speed then they are OK. Pass
2. Check angle sensor. Steering wheel, security access, then enter basic setting then steering angle Calibration, turn steering wheel slowly and check angles if seem fine. Mine jumps to an awkward angle and there is a noise when that happens like a click in the slipring. This happens twice from zero angle turning clockwise. No click or angle jumps anticlockwise from zero.
A third check I could have done is the yaw rate sensor functionality check.
maybe slipring failed because both front bushes failed?? probably will first do arms because steering wheel trembles when braking. dont want slip ring to fail again.
Note after the stabilization message ESP is disabled' so is ESP off button so is hill hold assist.
Purchased a 2011 second hand yaw sensor for future use. Expensive part, if purchased new, for its size. Future cost benefit risk assesment analysis I guess.

Changed today the 2 arms went for a drive and I have no steeringwheelstabilizer faults. Did not change clockspring. Will try to do angle senssor calibration Then reenable tpms coding and remove faults. Go for a ride and report.
Does not seem it was the angle sensor failing however the bushes failing can influence the angle sensor and ESP system. Will do more tests, premature thinking I believe .
Cost €110 for the 2 arms
Labour €30 ( incl. Changing the oil and oil filter)
Total €140
I suppose dealer charges would be higher.
___ update.
Tomorrow probably I will change the slipring because I was going to do it anyway (for ACC retrofit).
But it could also be the slipring failing. Got a stability fault again after starting the car.
Note my airfilter this time was in very good condition due to retrofittimg the air flow screen filter. (The filter swap I do it myself later at home after the oil change).
I am also upgrading my laptop miix 2 11 msata SSD HDD to 250gb (from 120 and I have to do hdd cloning so i have some other things to do), I should have also have done CP removal of radio concert but I forgot about it (this laptop miix 2 11 was only sold to USA right?? it is great as a tablet but as a laptop the worst I had. Yes this is the windows 10 tablet I use with VCP and VCDs diagnostics). However its memory cannot be upgraded and mine came with just 4gb (it is soldered, shame you lenovo).
I am also upgrading my silverstone home theater atx power supply to 450watt (from 300 watt, another USA product), worth showing my silverstone SG06 case HTPC because it is a piece of art. All parts apart from graphics card are same as one used in a laptop including WiFi card but I added external antennas for better reception drilled holes on rear metal plate). Have had it for many years but upgrading it occasionally, now graphics card is hungry for power. This just to have a break from the subject to have a laugh. Might get more responses from IT people.
Slip ringhas failed. Confirmed with VCDs. Still clicks at 2 angles and reading is incorrect at those angles.
