Hi all

went out shooting this morning, on the way way I got the dreaded HDC Disabled, Transmission fault suspension lowered Special programs disabled, however the suspension didn't lower and the car didn't go into limp mode.

So I checked the brake lights, neither were out, and then I had the battery checked at STS and it was absolutely fine.

So I decided to change the brake lamps anyway and found water in the connector, so I dried it out and spayed in some WD40, d dried again and then disconnected the battery and Voila, one working RRS again!

just thought I would share this in case any one was having similar issue

TMF

2006 RRS 4.2 SC

I had the same thing happen me to me, but it was found that my rear diff motor had packed up, luckily enough I had extended warranty and my local dealer replaced it. I was told that it would have cost me about £600 if I did not have the warranty

Hi guys I'm new on here and not to sure how to use the site so please let me no if I'm going wrong rite I have if problem with my 2005 rrs tdv6 I jump in and start it up and I get hdc fault system not available / suspension fault /transmission fault and the car is as low as it can go and will not raise also green lo mountain light flashes all the time with amber lights ether side can any one shed any light

Nick, it could be anything. You will have to have the car plugged in, to diagnose any fault codes stored.

However, the brake pedal switch is a very common failure, as is issue with the brake light bulbs.

It would be well worthwhile spending the £25 to replace all of these, just incase this is where your issue lies. There have been an alarming amount of D3's/RRS's left stranded by a faulty brake light bulb/switch

If the problem is still there after replacing the bulb and/or brake switch you could try replacing the fuel filter, especially if it has not had a good or regular service history. On my TDV8 RRS it was the fuel filter that caused the cascade of warnings. Good luck, and as Mikey said, try and get your codes read too. Regards, Marty

Thanks i will get it plugged in as iv change the battary for a new s5 bosch and replace the brake peddle switch .dont no if it makes a difference but my brake swich was blue and white but the one i got to replace it was blue and brown they assured me it was the right one but coule just have said that to make a sale .any way i will get it plugged in asap thanks

Also forgot to mention i blanked of the egr's but thats seemed to be fine when i did that

Just to add my input, I had the same problem, and new battery didn't help. Checked bulbs and all ok. So got a new brake light switch for £5 +VAT from Island 4x4 and it solved all my problems!

I replaced the brake light switch and still no different cost me £20 was blue and brown is there another brake light switch ?

i would start from checking Transfer Case ecu for corded connectors
from your description most likely the cause
have you power washed engine bay lately?

Ye i did power wash under the bonnet when i got it as the whole car needed i good clean ill have a look and see what i can see thanks

So at least no one else to blame
