Coding Out RPA/RDC Tyre Monitoring

Recommended Posts

Hi all,

 

probably one for gonzo as it's coding, I want to code out the rpa/rdc tyre monitoring system. It goes off randomly every couple of weeks and if I check the tyres there pressure is at most 2psi different so it's not overly accurate and it annoys me.

 

In ncsexpert I've ran codierdaten_lesen on all the ecu's listed individually and set any reference to rpa or rdc to nicht_active followed by coding each ecu with sg_codieren but when I go into the idrive vehicle settings RPA is still there, is there a $ code in the vo for the tyre monitoring if not I'm not sure what I've missed, anyone any ideas?

 

thanks

chris

Glad I'm not the only one then, I know the system works by monitoring the abs sensors and a flat tyre gives a different reading but I'm no where near that when it goes off and frankly I don't need the car to tell me to look at my tyres, my wife on the other hand...

Not figured this one out yet as it seems to be rotational or pressure valve monitoring (USA)

Noticed earlier my rpa screen now has the initialise option greyed out and below it says system error which should stop the flat tyre notifications , I need to work out how to remove it from the vehicle settings screen completely to satisfy my ocd

Do you reset the tyre pressure monitor each time you check the pressure? What's the build date? I run 2.6 bar at front(245/35/R19) and 2.8 at rear(275/30/R19) the only thing it activated was when my old front tyre had a slow puncture at 1.7 bar...

No I don't reset it everytime I check the tyres I shouldn't have to given I use the same pressures from the door plate each time.

I do that every time it gives the flat tyre alert and a couple of weeks later it does it again somethings evidently upsetting it and it's jot the tyre pressures so I'd rather just disable it

You have either a $2VB for tpms or $265 for a tire pressure monitor. Delete it from cas(if you read it from CAS) then FA_write to CAS and LMA. the quickest way would be to use the factory reset profile and do SG_codieren to CAPPL, KOMBI and DSC. if you want to do it manually it would be the RPA you need to find and disable. hope it helps.

I am guessing you have $2VB if you want to convert to tyre pressure monitor from RDC then enable above function

Thanks I'll look at it tomorrow, I did wonder if there'd be a string in the cas but couldn't find and information for what it might be
