Thread: Radar cruise control?

Chris, you don't have to run the 'run-flats'........I have changed every car I have ever owned that had them standard over to normal tyres and just carry a can of emergency goop. There is no advantage in run flats.......you can't get one when you need it, they are exorbitantly priced, they wear early because of the super stiff sidewalls and are very dependant on constantly correct alignment and pressures.
Get rid of them and get your comfort back.......ever see run flats on Porsche, Ferrari, Lambo, etc.......nope. They're rubbish!

Resume normal programming now........I have finished
Grant

But make sure you keep the run flats and wheels somewhere.


My son's new wife tried to sell her very nice no immaculate as her dad is a detailer 2006 BMW 325i recently.
They tried first on Carsales and then left it with a trusted dealer friend to sell on consignment or to the trade.
They ended up getting only 7.5 K as all buyers particularly Trade wanted the original Msport wheels .
Go Figure!!

My ACC radar uni, bracket, wiring harness and replacement left switch pack arrived today. I now know why the new/unused radar unit was so cheap - it's missing 1 locating grommet/cup. Not a problem though as I'll easily fabricate an alternate if a replacement cup can't be sourced.

I finally got to remove the front bumper and fit the radar unit, for which the supplier had supplied the missing cup that he hadn't spotted was missing. The short link loom previously acquired connected the radar unit to a nearby connector that had been plugged into a dummy connector. CCF changes have been made and the new left steering wheel switch bank fitted but now need to calibrate the system. The instrument cluster ACC symbol is displayed on start-up but 'Forward alert not available' is displayed after start-up and 'Cruise not available' if any of the CC buttons are pressed. My Faultmate Extreme has a radar calibrate function so will see tomorrow what can be achieved.

A slight hiccup - the radar unit is programmed for a Jag, not my RR and doesn't want to re-flash with LR firmware even though it is the same hardware. It was advertised as the correct LR part number (LR029157) but only labelled with a firmware assembly number (CX23-9G768-AD) which at the time I was not able to decode to spot the misrepresentation. Unless the failure to accept a re-flash can be overcome quickly, a replacement correct module (BH32-9G768-AD) will be acquired as used ones are readily available and as a bonus may not require calibration.

Gap Diagnostics have provided a reflash that has converted the radar unit to the correct RR version and are working on a calibration option - great support!

It's quite amazing how quickly Gap has been adding functionality to the iiD tool across the models.

ACC activation has been put on hold for a few months due to the task of adding the radar calibration function requiring more work than expected plus other priorities so standard CC is being re-activated. Not only do the CCF parameters have to be reset to standard CC but the original steering wheel CC switch bank has to be refitted as the data format from the ACC switches is invalid for normal CC. Maintaining 100 kph at 1250 rpm without CC requires constant attention which detracts from the otherwise effortless driving so worth the effort to temporarily change back.

Update: It wasn't the ACC switch bank preventing standard CC from working, it was unexpected data being sent by the radar unit, overcome by removing the ACC fuse from the engine bay fuse panel.
