'03MY L322 Petrol 114k5 miles

Above says it all really. Never had an SUV before let alone a Range Rover. So up pops this one at a price that couldn't be turned away. And that says it all!

This one's got some repair history. I have the infamous NSF ABS speed sensor fault showing "open circuit" on my iCarSoft i930. Together with the usual array of icons on the dash and message showing Air Suspension inoperative. Yet, after parking up overnight, starting again in the morning brings normal operation until about 20 miles later when the "Bong!" of gloom sounds and the icons come up again with no apparent change of car performance except the suspension heights can't be changed.
Forgive if there's a well thumbed thread about this or a FAQ -- and point me to it?

I should add that during the previous days I hadn't heard the suspension compressor softly whirring coming from the rear. But last night (after going thru all the suspension changes, I did) And today whenever there's a suspension height change, the compressor's heard and then shuts off.

Strange thing is that if you park up and switch off. Then wait say five mins the fault does not immediately return but comes back about 10 mins worth of driving later. Overnight switch off
gives you far far longer driving before the fault occurs... So I'm discounding for the moment bad connection, chafing of badly installed sensor cable etc...

The repair history shows sensor being changed in September 2017 but with what appears to be a cheepo Chinese clone that cost all of £22 inc. p&p. Each! There's no record of the fault returning until August 2018 when it showed up again. I've got a repair shop in Leatherhead lined up to change it for an OEM sensor next week. But in the meantime was wondering what else could I be looking at?

There's been some dark talk of the EPV (whatever that is) being at fault -- AFAIK it's some kind of computer module that controls the air suspension? Today I did 22 miles mostly motorway and all the functions of that -- going down to Motorway mode, and returning to normal mode, Access mode going down to lowest, etc. -- work fine. Yet, just when I thought the fault had gone (I've only had the car four days when the fault was mostly in the first five miles or so) I stopped to talk with neighbour on way back and without any steering input the "Bong!" came again...

Grateful for any guidance this ignorant can get...

Worth checking the battery condition and the alternator output. Low volts causes all manner of problems

I would be looking closely at the sensor and its cable - the cable if not routed correctly can rub on the inside of the wheel rim and cause issues.

The EAS will go out if there is an ABS fault.....so I think that is something to pass over at this stage and give the ABS system a good looking over.

Just to add to the above, not related..

Best make sure the Auto box is in good order, its around 100k they start showing TQ problems on the 5hp24.

Havn't yet done that yet. Nor checked the manufacturing date of the installed battery -- it's a Varta Blue with a barcode sticker on the top but think that's just someone's stock number rather than Verta's manufacturing date code. This from the Piston Heads site in 2015: "there are four numbers on top of the battery post, the negative one I think. The first two are 01 upto 52, which is the week number, the other two are the year." This info is also posted in Jaguar Forum.
There's no brightening and then dimming with revs of any filiament bulbs that I can see (my old Avo's busted).
When it's a bit brighter and warmer later today will check further. There's no starting problems and all displays are correct until tbe "Bong!" of gloom, some miles later.

Are there any precautions to take (like losing codings, radio code?) when disconnecting battery. I want to see what's stamped on the negative terminal

Thanks for taking the time to reply, well appreciated

Yes, don't have any service history on ATF and filter change.
Taking the top of the resovoir off shows very blackened ATF.
No faults showing on my iCarsoft 930 for gearbox. And the changes up and down are really smooth.
If this turns out to be a keeper (Halogens, Sunroof, clean interior, original 'phone, Prinz LPG, navi, but can't seem to see the CD Autochanger unit anywhere (?) then will have that done.
What's a "TQ" problem?

Slight tick on tickover when warmed up. Is there a timing chain tensioner to change or adjust on this BMW lump?

See that bird? I've 'ad 'er...

Didn't even know the sensor cable could possibly be so close to the wheel rim. Will have a look. There is a slight clunking coming from that NSF corner too. But seems to stop after a few minutes driving. I've come from Jags, and before that VWs. Both had reported faults of the reluctor ring either dirty, or moving out of true, or even breaking up to give an ABS fault. On VWs (when switched on) because of the difference in speed reading from a faulty ring, the Tyre Pressure Monitoring System shows a faulty tyre!

Ref ABS system needing a good looking over. Would if I knew what I'm meant to be looking over for! Just been out to check again and yes, the same fault's there but not on the dash display. All air suspension (with comforting whirr from compressor) heights are selectable. On the iSoft i930 shows in ABS system: "0021 Front Left wheel speed sensor open circuit." and "005A Temporary System de-activation" But the iSoft "failed to clear" these faults. Some faults on Jags the iSoft can't clear either.

Reading around on the forums there's been mention of an EAS reset. I don't know what this is nor how it's performed.

Thanks for all the replies so far guyz.
It's all new to me so all challenging

Sounds like a keeper to me

TQ = Torque Convertor . Do a search on it and you will find lots on symptoms, issues, remedies and cures. Especially relevant if you have nothing showing it to have been dealt with before now. Also check your 'sealed for life' box, to see if it has been opened and at very least an oil change done.

You sure?

First I've heard of an ATF reservoir.

Your one, is it just beside the coolant tank, cylindrical in shape with a knobbly edged cap?

I don't believe in "sealed for life". Nor should anyone else: 80k miles for VAG's Aisin Warner Tiptronic box (VW were saying "it's sealed for life, sir" to anyone asking. VW north America blew the gaff by putting it into their service schedule for their region's cars Jaguar are now quoting 60k miles for all their boxes. Instead of main dealer service departments' receptionists sniggering at any customer enquiring.

Yes, I've got no indication that the ATF or filter's been changed. I did ask previous owner who's had for a year and he hadn't changed ATF either

Couldn't see anything close to the wheel rim. I'll try seeing whether I can upload a pic on this new-to-me board
Hmmm... all I'm getting is "there was a problem uploading your file". The other option is a file sharing gallery -- I used to use Photobucket but that's gone now...

I doubt there are any on here, for more than 5 minutes, who believe in sealed for life. Hence, my suggestion of checking it and the phrase being in apostrophes.
If you have no proof positive, then it should be high on your list.

Ticking is most likely the Vanos, however the M62 has a peculiar Timing chain tensioner set up they can get tired, they need to be inspected and/or replaced around 100k..

The upper chain tensioner is the little thing to the left with the metal coil sticking out of it.

In my experience the O-Ring that seals into the oil gallery in the cylinder head can break down, and leak oil, which in tern lessens the pressure applied on the tensioner.
Also the platic can wear and eventually the tensioner won't be able to compensate again causing a light tapping, as it wears the noise gets louder....

HOWEVER!! Vanos is the biggest M62 Gripe they also tend to make noise..

So long as it doesn't sound like this..


Which was a few failed tappets from lack of oil pressure an an iffy tensioner which is fixed now . .

The Transmission does require a good service every 50-60k it has an inherent fault with the Torque converter, and keeping the fluid fresh and clean gives it the best chance of survival.

Don't wait till it gets rough.

I don't know what VANOS is

Coming from XJ8s (three off) with the AJ-V8 timing chain tensioners were a favourite to fail. They were plastic and split vertically. So I had all of mine done. Two out of the three sets had their plastic cracked just waiting to fracture apart (the other car had been owned by an enthusiast so was already done)
Once this NSF ABS sensor fault's cleared and I'm confident it's not going to come back then I'll spring for the ATF & filter, and the upper chain tensioner as you suggest. Again, your adivce very welcome!

No, the one with the knobbly edge next to coolant resovoir AFAIK is Power Steering resovoir.
The one I'm referring to (not described but shown on the diagram) is forward of that with a large hex
shaped nut and a max Nm torque setting stamped in the plastic moulding

VANOS stands for something technical in German that basically means varible camshaft timng.

The M62TUB44 engine uses a system to vary the intake cam timing using a hydraulically operated gearset....this is the VANOS unit.....the internal seals can fail causing a rattle and ticking noise......

Heavy rattling and slapping is worn main chain tensioner or guides as they were also made of plastic, and fail.

Couldn't of said it better myself

THAT is the engine oil remote filter housing, NOT an ATF fluid reservoir.

I feel it's rather important you know that, in case your tempted to a transmission OR engine oil change.

So when you said, "that bird, I've ad her"......describe ad for us please?
I fear her version of events may differ from yours.................a lot.
