L320 TDV6 multiple issues at once with power drop

Hi all,

2010 3.tdv6 sport. 130k miles. 2019 front end damed but repaired. And ran since For 30k miles. Stamped service book but have my reservations about the latter services so first thing I did was oil service.

Had it 3 weeks was fine apart from front passenger side suspension always seemed to sit ever so slightly higher. Couldn't tell visually but the 4x4 display seemed to suggest this.

Compressor kicked in some mornings but not noisy. So bought car anyway thinking ill get that looked at soon.

Changed all 4 tyres on Saturday there and went for a jet wash after. The black circles guys put the car into offroad mode however left the car jacked up using 2 trolley Jack's at the front for over an hour....as they were short staffed. I mention this for context as I wondered if this might be linked as problems arised not long after.

When tyres fitted I drove off fine. Went for a power wash and all was OK on the new tyres. Or so I thought

Then on Monday morning having not really driven it much I went to go to work and within a minute I felt a dead spot while accelerating.

Almost like a bad fuel filter feeling I've experienced before. Stopped at a junction I tried to pull out and bing bong 4 warnings appeared. Stability control unavailable, park brake fault, gearbox fault and emergency brake assist unavailable drive with care. (Yellow).

I was able to continue albeit felt the car losing power under load. Got the car safely to a stop and turned it off and back on and the errors were gone but the power loss remained. The warnings have appeared again once on route to my mechanics but were not on when I got there.

Unfortunately my mechanic only has a snap on code reader and after an extensive read , took 10 minutes to read the modules gave me nothing for suspension but a LOT of communication codes with various modules. Key fob, fuel level, fuel filter to name a few (I'll get a photo next week).

He couldn't work on car there and then so as I went to take car with it being sat with ignition on for the code read but not running I noted I had a low battery warning, please start car. Car started fine as it always does. So suspected bad battery or alternator and booked in the next day.

Battery tested and other electrical checks and mechanic states all appears normal and he has suggested I start with a new fuel filter (Mondays job)

I have seen another similar thread although it centres around HDC but seems very similar symptomatically where a ride height recalibration sorted the issues. It just feels electrical to me with all these appearing at once and feel like I might replace the battery anyway despite what my mechanic has said about my current unit. He can't do a recalibration though as he isn't a LR specialist.

My issues will be getting it safely to a landrover specialist able to recalibrate the ride height as the closest one is 16 miles from me on fast A roads and don't really want to risk losing power or causing an accident.

Anyone else experienced similar? Could the jet wash have done something? Could the black circles guy have cocked something up changing tyres? Is this all a horrid coincidence?

Any thoughts appreciated.

Thanks D

I would not be surprised if the jet wash has caused a problem, water ingress is a common problem just from rain, a jet wash would make it worse.

Could well be water ingress but I'd check the battery is fully charged too

Thanks folk. Yeah that's why I mentioned it as that was a consideration, but funny it didn't cause any issues straight away and rather a day or two later with normal use and without issue.

Another thing I noted was the previous week I put in a Bluetooth receiver to the USB which worked great for music and left it plugged in. I wondered I'd that being innall the tome was slowly draining the battery or something as I was also only doing shirt 4 mile trips last week too.

Mechanic said battery fine but I never Seen results for myself so I might just go down that road first

when I get car back on Monday.

Low battery volts is a common cause of problems, after leaving over night you should see 12.6 volts or more, with the engine running, shortly after starting, you should see at least 14.5 volts.

So I've been reading. I have a meter to test this but car is at Garage at present so can't test. Certainly no battery warning prior to problems arising but did see tue warning as I say after the mechanic scanned with his snapon.

Where should I start to look to troubleshoot you reckon, assuming battery is as mechanic states OK?

I've just bought myself an icarsoft to get codes for myself next week so I don't have to reply on the garage. Hoping it works OK as seems fairly cheap for what it is.

Thanks again for your time in replying to me

A failing battery will cause all sorts of funny warnings so needs to be ruled out. How was it tested?
Our L322 liked to throw up a gearbox fault, would only stay on with the radio on for a few minutes before the low battery start the car came up. Like you it always started the car no issues. It got slowly more frequent. We don't do many short runs but as you say you have been lately then it could easily be to blame.
New Battery installed and it has been fine since.
I still use the battery (keep it charged) in the garage it works as a jumpstart battery fine so even though it was no good on the car its actually still seems quite good.

As for the jet wash, It shouldn't but the LRs today don't seem to like it up em in the wrong places so its possible you have sprayed high pressure water at a connector or its leaked in through a body seal and got in somewhere.

Interesting input and thank you for sharing your experience also. I guess I'll hand clean it from now on assuming I get it back on the road fully healthy. Worth trying a new battery then just in case and if nothing else it's one less thing I'll need to replace in the future.

I don't know how he tested it all he said was "tested the battery and other electrical items and all appeared normal" I presume he's used a multimeter or his scan tool has a battery voltage test function.

I'll ask him on Monday

If it is a jet wash what do you reccomend I look at trying to dry out or replace? Something near wheel arches I presume? Ride height sensor?
Thanks

It would certainly be worth checking the Ht sensor connectors and the L320 has its compressor underneath behind a cover, there could/probably be connectors in there to.

The jet wash may not have anything to do with the problem, we use 1 on ours (once or twice a year) its just something to be aware of.

Thanks. This is a great forum. More response than any other of seen so far so thanks very much for that. It is genuinely really appreciated. Yeah I'll keep an open mind re the cause and trust mechanic for now but great info for context and ideas for troubleshooting.

If you change the battery go for the biggest ah and cca one you can fit in it, dont just go by what the chart says as some trim models take a bigger one than the book says .

Oh and I forgot to mention another gremlin I noticed before all of this.

Heated seats didn't seem to work or at least heat up properly. And cruise control worked but when speed set would speed up on its own, that was the first issue I noticed.

The round tailgate button doesn't work. It's seized bit I know that won't be linked. Have a new one to fit though.

I was going to go for this battery. Thoughts?

Check the physical size of space you have, Then as above biggest capacity.
I don't know how much space you have.

I fitted an S5 A15 bosch battery it was a tight fit for the L322.

Thanks Marjon!

Before fitting a new battery, it will need to be fully charged. From the supplier it may have been sat on a shelf for ages, they rarely come more than half charged.

Thanks Datatek! I'll definitely do that!

Can you reccomend a decent charger to buy?

Lidl/Aldi often have smart chargers. Personally I don't recommend Cteck as I think they are overpriced. Google 4 amp smart charger, there are loads for about £25

I thought a 95ah battery would have required a higher amp charger. Thanks for the tip

If you can afford a higher current charger that's fine but they are very expensive. A 4 amp charger should top up the battery in 24 hours.
