My 2019 Disco 5 makes a series of thuds (usually 2-4) which sound and feel like they are coming from the transmission. It usually occurs shortly after standing overnight in slow moving traffic on a slight uphill incline. After that it can be intermittent with an occasional judder feel, usually at slow speed with light acceleration.
I have tried to eliminate the gearbox by holding the car in 1st on the tiptronic and the thudding still occurs.
The local LR dealing has been unable to hear the noise even after leaving for test drives overnight, but then I feel it as soon as I drive out of the carpark.
It only has 25k miles on the clock. Have suggested flushing the transfer and gearbox box but that’s expensive unless know the cause. Others have suggested the automatic parking brake but it’s a clear thud rather than a screech.
Any other suggestions for me?

Hi

may I ask have u had diagnostics plugged in plse and if so any codes

Personally am with u regarding flushing gearboxes , also wouldn’t have it done, , Maybe the gearbox needs a software update ?

out of curiosity does it make a noise with the wheels dead straight or only when u turn the wheel left or right plse

know that’s not much help but at least starting with diagnostics ur be able to see if any codes come up and then go from there

There is a cheap diagnostic reader u an get for around £60 , let me check for u first to ensure it will work on ur year of Landy

hope that may help a little

FIXD shows no errors.
Veepak lists the pending codes shown in the attached.
When I took it to LR first time they performed an Airpath Routine Setup, but I have no idea what that would correspond to.
Can’t 100% be sure but I think it occurs on straight and turns. Seems to occur most often on slight incline and slow speed.
Checked for trapped cyclists, none obvious.

many thks im afraid that elm 327 might as well be thrown in the bin as useless on a discovery 5 , need a good scanner like a gap iid , cheap ones will give wrong codes etc and send u down the wrong path

Do u have a good independent garage that can plug a decent scanner in for u

might be ur steering wheel angle sensor as if that’s not reading true can also cause issues

first ensure ur battery is in tip top condition and fully charged along with the alternator working properly

sorry that’s not much help, only advice I can give is finding a decent garage , personally don’t go near Land Rover dealers as found them very expensive , customer service terrible and can sometimes be rude

plse let us know how u get on

A couple of you have mentioned steering calibration. I'm not sure how it would impact this noise but I notice (with reasonable certainty rather than 100%) that it seems to occur when steering slightly to the left on a slight uphill. Would this make any sense?

I can't see how an air path calibration will help with a transmission or driveline fault. Besides at 25k it shouldn't need it, as it's unlikely that any intake sensors have been changed.
