Auto Ride Light Bleep 1993 Turbo R

Is there a reason why the Auto Light seems to bleep as I pull off or sporadically slow down in normal driving?

The Auto ride beeps when an error code is generated by the Autoride ECU. Fluid levels have nothing to do with an error code being generated. An issue we find sometimes is just a dirty connection at one of the strut solenoids. I would clean the plug connections on each strut and see if that cures the fault code generation. If not you need to plug in the ECU test box to determine what the error code is. SBI Electronic Engineering in Bolton makes the test boxes and rebuilds the ECU's. You should read the appropriate section of the shop manual for an understanding of the Autoride system. The only thing you can do without the test box is to check all the wiring connections for good connectivity. There are accelerometers in the ECU that measure G forces as you accelerate or brake, if it is beeping only as you do those actions then it's most likely one of those out of alignment. The test box will realign them if they are just out of adjustment, but the only way to do this is with the test box. A Rolls-Royce specialist may have either the factory test box or the SBI test box, you'll need to find one who does.

I have not noticed any hard rear ride. I have the car up on axle stands now and will have a look at the connections, if I find them. I would say that getting this car up is a revelation, just as well I purchased a high lift jack and lorry axle stands. Some formidable beast and really important to follow safety procedures. I put the stands at the rear sub frames and front wishbones with wooden isolators. I did read the procedure for topping up the LHM fluid in the owners manual, seems rather complicated to say the least.

They will beep if the fluid is low. But if it is "Auto Ride" this is an electronic issue and will beep also when it is displayed.

Adam - you can check the level of the LHM by looking at the sight glass. There is a green marker that should sit between two lines. If you need to top up, getting the LHM in requires the correct attachment on the bottle - there is a spring loaded ball valve in the filler which wont allow admission of the fluid unless it is pushed down. It is possible to do it with a screwdriver or something, but not ideal.

However, it sounds as though your issue is electrical.

I was due to collect my Turbo R from various work such as new rear suspension cups and brake pump rebuilds. That work is complete.
The last issue was the auto ride bleep and hard ride.
This is how it was explained to me. Yes a plug in diagnosis would give one but he doesn't have the tool, will invest in one at some point soon.
Apparently if there's a fault with the ECU the suspension reverts to sports mode thus the hard ride apparently intermittent. Gas shocks/spheres deemed good. So next port of call will be to send the ECU to Guru 'Op North' who will check and do his tricks. I note this is in accordance with Jim W above.Watch this space, will report back.

it might be worth checking the cables for continuity from the front inner wings to the struts.....on my 90 turbo R the cables looked ok externally but the actual conductor inside was broken and would play up intermittently.......took a lot of cable wiggling and a long time to find.
