Hi, me again, don't no if its coinsidence but had alternator fitted last couple days, today the dynamic response light has come on suspension not raising or lowering, do not drive over 30. I checked fuses and all ok, changed battery with new alternator, checked voltage and ignition off its 12.8v and running it 13.9v any ideas.

Yes checked level in bottle near airbox, all correct, I'm so confused.com this beast is really trying me at moment...

Read fault codes.
Is the light yellow or red

Unfortunately not got access to code reader anymore, will have to get codes read by garage. 😔 the light is red.

Could be cause by all sort's. The fact you've had an alternator changed and it's just gone might be a coincidence, or the garage that were changing it may have disturbed the ABS sensor while doing the job. If you've had the tracking done that could have thrown it out.
Does the 4x4 info screen show all 4 wheels as being the same height (on level ground of course) ?

Hi, mechanic went in through the front to change alternator but did have to undo dynamic response (ACE) pump to make room to remove alternator, 4x4 screen seems all ok, car states standard height, car looks standard height. All looks level on screen and outside.

He may have disturbed something/not put it back right hence the warning.....? Visitor from fullfatrr.com

Yes, hopefully it's simple fix will mention it to garage this morning when give them a call.

Are you sure you have dynamic response on the car ? As its only fitted to TDV8's and S/C's as standard. Was an extra on the V6's. The light on the dash can come on with General sus faults as I found out the other day working on a basic disco 3 2008 G4 RRSport TDV8 current
2009 TDCi 90 current
2018 Discovery 5 HSE lux current
1994 Dakar current

Hi, yes def got dynamic response, I've got the filler resiviour to the left of rad, by air box & I've got the pump directly bellow alternator, think the car had few extras when purchased new, it's got Brembo front brakes and 20" wheels. Hoping it is just a standard height sensor or similar, could it be air compressor failure as the front did raise very slow the last time I used it and got message (suspension raising slowly) thought that may of been because I went through the raise & lower procedure a couple times without letting compressor have min to recoupe.

Just got call from garage, they have done diagnostics and come up blank, they said it looks like it's a faulty alternator as it's overcharging and looks like it's shut down the suspension. I've tried calling advance factors but the number provided on invoice says no longer in service, can anyone point me in the right direction to contact them..

That's crap, When they removed the ACE pump did they disconnect the hydraulic pipes ?

The ACE system is self bleeding but needs to be "convinced" to take oil. When I replaced my ACE pump it didn't want to draw oil under it's own volition. I had to pressurise the reservoir to get oil back into the pump.

There will be fault codes relating to low pressure from the ACE system. I'm in Somerset (Taunton) where are you taking it too ?

My money is on it either being an air locked pump or more likely that the mechanic hasn't routed the auxilary belt correctly.
