QuestionHi,
I own a Discovery Series II, TD5, MY 2000 with ACE and SLS.
Since April this year the car produces "knocks", when you are cornering at low speeds. The dealer order some bearings, fixed them, knocks are still there, searched again, and exchanged the whole ACE Assembly on the rear axle. The knocks are still existing(Dealer says, some noises are now no longer present).
Today a specialist from Land Rover was at the dealer and we were going driving, back to the garage, trying to fix something, and going driving and so on.
We were able to locate the ACE system as the source of the knocks, with the ACE-Relais R14 removed there are no knocks when cornering, also when going reverse, also when the ignition is switched off and car is rolling.
When we are cornering (slalom) at 10-15 mph the knocks occours at every change of direction, when we go right-straight on-right or left-straight on-left the knocks occur only on the first change.
We tried to remove the air from the system on the front-axle with testbook procedere, we did the ACE test with the test book some times, where the whole car shakes and the result should be, that the ACE Valve Block should be the defective part.
Is it necessary to exchange the whole valve block, which is about 1200 Euro, or could this be only one of the solenoids not working properly or the pressure-sensor, which delivers not the correct values (and so the system "overpowers")?
Testbook did not find any errors, I had the ACE warning lamp turned on only once a long time ago. Car has only 84000 km, and is used 99,9% on road for pulling my heavy trailer (only been twice on an offroad-yard).
Thanks in advance,
Christian (Germany)
AnswerI don't think so. Mainly the anti-roll bar's 2 mounting rubbers, use to wobble. Or the ACE actuator cylinders mountings can wobble too. And if you just go on rough road at straight direction?
So, these are the main problems which can cause that noises.
If you send me an e-mail address, I can send pictures to 100% identify the parts i've talked from.
