What did you do with your Range Rover today

Have another play and turn off EKA if you haven't done it already.
Is the speedo over or under reading in mid range?

I think I turned off the EKA too but not sure. I don't find nanocom completely intuitive.

Speedo accurate to about 25mph, and from about 65mph upwards, but under reads by 10mph consistently between those according to 2 different GPS speedos.
If in doubt drop to 3rd and revs give a check at 20mph per thousand RPM.

Take a look at the ABS wheel sensors live data and check the ABS ECU for any fault codes.

speedo should never read 'under'. if you have larger than oem wheels then its a possibility

There are a couple of pots on the back of the instrument cluster that calibrate how the speedo shows the speed signal given from the BECM. I'm sure I saw a post from someone who fiddled with them. Might have been on here or RR.net. Might be easier to try a spare one off eBay although remember the mileage has to be lower.

Don't know what the eff I've just done.
Green flag is £112 pa so cancelled renewal and went to sign up with autoaid and have just received an email confirming I'm with emergency assist FFS

Oh well, it was only £25 for 12 months personal cover.
Although there are some shìte reviews

Possibly. They'll be on the back. Someone explained what each one did in the post. Mine pretty much matches the GPS at all speeds so whoever did mine at the factory must have been on form. No other car I've ever had has been that close. Means it can be done!

I don't know if it is the ABS module or the BECM that calculates the speed, only that it counts the pulses from each ABS sensor, averages them and the converts to speed (4000 pulses at 60 mph rings a bell). Should be pretty damn accurate unless a sensor is acting up and then you'd have a fault code. Probably the ABS ECU but either way, the BECM then converts that to a voltage and feeds that to the instrument cluster to move the needle. The needle is calibrated accordingly using the pots - think he said there were 2 of them for some reason.

So after getting my height sensors to work properly the other day, the Green P38 decided to throw me another problem today.

Was on the way to Reading & Aldermaston, and the diaphragm valve failed just befor J10 on the M4, allowing the compressor air out the exhaust port. Had to turn round & drive home, although luckily it didn't hit the bump stops until about a mile from home. Moved laptop & stuff into the Blue P38, and got to Reading about 12:00 instead of 10:30 !!

Swapped a diaphragm from a spare valve block this evening, and all up in the air again
