Yes, there's an a missing, it should have said what sort of area in case someone has experience locally..
When you say it rise and inch or so, do you mean from the position it was left in? It will always drop very slightly as the air in the system cools down, so rising slightly as soon as you start it is correct. Unless you are getting the constant stream in the two boxes as shown on the video, then it isn't connected. Some USB-serial adapters work fine (usually ones using the FTDI chipset) while others can be very flaky. Have you installed the drivers for the adapter? What operating system is your computer running? What Com port is it setting itself up as? Ignition does need to be on or engine running.
It rises an inch or so when i restart it after a few hours or a day, which from what you said sounds like normal.
I installed the drivers for the USB, as the OBD lead connects to the USB lead via the 9 pin adaptor, I presume that is what you mean? No driver for the adaptor specifically came with the CD. If this means that there is something better that I can buy i am happy to do so, I don't want to be wasting time with dodgy equipment. neither do i want to be wasting my money.
The laptop is 11 years old & runs Windows Vista Home basic. It is using COMMS port 4 or 5 [depending on which USB port on laptop I used, I tried both to see if it would make a difference, which it didn't], but shows as something like USB [plus something else which i cannot remember] All the others just said Comms & a number, so i presumed the USB one was correct. Plus i had the ignition on.
As I think this is the UK site do you have recommendations for any independents nearby who I might use in the future?
I will try & locate the relay & check the pins over the next few days.
Where is the best info on changing the bags? I have downloaded RAVE & just had a quick look. It doesn't look like too difficult a job, although the YOUTUBE video intimates that disconnecting & reconnecting the pipes can be tricky? Do you have to depressurise the system? If yes, do you do it via the EAS unlock software?
Also do i presume that if the EAS system comes up with no faults, but the 35 max warning keeps coming on, even after resetting [that is presuming that the EAS etc is installed OK] , that there is likely to be a fault which needs checking out by a RR garage, because the fault will only get worse & potentially more expensive?
Happy new Year
