This might be a total noob suggestion. But the previous owner fitted 22 inch wheels aftermarket. Would this have this kind of effect in the cruise control due to the amount of distance covered per rotation of the hub being different from...
There are no relays on a L319 CC system, the inputs are direct voltage from the switchpack, brake pedal & composite speed signal from the ABS, broadcast on HS-CAN and transmission temperature (as an inhibit), again, on HS-CAN. It's a pretty...
Sorry no. Don't have access to manuals for RR after 2006. The earlier L322 manuals say it's done by the Engine Management ECU, so maybe there's info there ?
Doesn't seem sticky but I noticed the '-' button doesn't slow it down. It just races away past the speed limit. I figured if it was sticking it woukd set itself also. But doesn't. I'll get a look at the live values. What's the best and most...
The cruise control is a relatively basic function, there's a resistive ladder in the switch pack that sends a specific voltage to the ECM - which has the CC supervisory function on HS-CAN.
The first step is to look at live values from the...
I have never trusted cruise control since I experienced a 'surge' when travelling up the M1 in my old Jag, scared the bejesus out of me because it did n't respond to braking or adjusting from control unit, turned out to be a faulty relay, but put...
Hello again all
How are we all this fine easter Sunday?
Another gremlin with the 2011 RRS TDV6 auto.
Set the cruise control to a set speed but regardless of the set speed it continues to accelerate beyond and continues until you hit the brake...
So starting to think it's 100% suspension related. The power drop is the first noticeable symptom if I don't have 4x4 display up however passenger side front wheel does start to act up sitting around 20mm lower than it should.
When all the...
Ordered Brake Light switch this morning.
My mechanic has tested electrical system (so I'm told) and found no faults. In fact he couldn't recreate the symptoms I am experiencing. They come and go and appear when I use the vehicle more. So I will...
The first thing you should deal with is the brake pedal switch, check the wiring, if OK, then replace the switch. All the other powertrain & chassis errors will 'cascade' from that one, 'Vehicle Dynamics' errors can only be from other systems as...
Try graphing the alternator output if you can. It's possible the alternator isn't outputting the correct voltage all the time, so the battery has to take up the slack. All those lost or invalid comms codes are likely due to low voltage on the...
Hi all
2011 RRS TDV6 auto
Trying a post here to see if someone can offer their advice. Forum user Bison posted a few years ago about the same symptoms and a ride height recalibration sorted it out but not for me.
Car has been losing power ...
So managed to somehow jinx it and all the errors came back. Symptoms started with losing power Intermittently. The air compressor was kicking in while driving here and there too. Then ping. Lights all came on and stayed on. Scanned the car and...
No issues since and today the car nearly died a couple of times after initial start when pulling away from lights.
Scanned the car and only faults are
B103C-15
And another for digital radio.
That's it.
Got me home but very disconcerting...
Hi all
I have no warning lights for this or codes but ive noticed that the fuel cap although turning until it clicks isn't actually threading and locking into place as it should, I have also noticed the fuel tank opening isn't square with the...
Sounds overly complicated and I'm sure you agree a little above and beyond. Diesels are dead, strangled and manipulated to hell for their dirty crimes...
The amount of complex crap I'm seeing with questionable build quality is disgusting. We are...
Sorry, manufacturer-speak - in this case, module = assembly, the pump is encased in a tub with various other bits.
There are manufacturers that have pump control modules, notably Merc & Renault (and I think VWG) where the requested and actual...
Just done an adaptation on a Volvo xc70, running with just a percentage of its oil capacity. It eventually ended up trying to force itself to lock the tc up causing a fault saying the valve was stuck open ... After putting 3.25ltrs of oil back...
Fuel pump pre-filter blocked in tank, I've had many, many of these in the past with those symptoms, eventually it'll get bad enough to set a DTC - sometimes it's caused by fuel 'bloom', sometimes by cr@p fuel from too cheap sources....
The...
