SDV8 Front Suspension Knocking - LTB00557v8 - Help Needed

Hi Gents,

I am dealing with the famous suspension knocking issue on the 2014 SDV8. Car already been 2 times to Hunters with no luck yet.

On the 1st visit they have replaced the bushes and the lower control arms. It was an improvement but knocking is still clearly audible.

On the 2nd visit, i mentioned the LTB00557v8 and the service advisor said they have carried that out and all my anti-roll parts are replaced with the latest available. Massive improvement on the handling, car feels much more tighter and flat however knocking is exactly same as before.

I recently bought the car have had some other issues ongoing with the suspension. They have sorted other bits but as it all added up i have spoken to head of business to reject the car by saying i have given them enough opportunity to rectify it. But in reality i like it and i would like to keep it Smile

He put me in touch with the workshop manager who explained ARC valve block was not replaced on the 2nd visit under LTB00557v8 as the bulltin does not instruct upgrade of the ARC valve block.

Guys at Hunters are trying to be helpful, i have mentioned about this forum and the information i had from here. They have kindly asked if we can provide a registration number that has the knocking fixed. Hunters are happy to check history of that car and do whatever needs to be done on my car and the other cars to follow.

Car is booked in for this Friday for the 3rd time, i am going for test drive with senior tech, and also they promised to arrange post 2015 SDV8 car to go out again as i mentioned post 2015 cars have the newer design twin damper ARC valve block and should not knock.

I know there are few other open topic which i have read them all but wanted to open new one and share all my experience to give it a bit more visibility under the new topic.

Sorry for the length but i am hoping this should help anyone who has deal with this in the future.

As far as i know new design came in after August 14 cars. MY15 should not have issue with ARC valve. I hope your issue due to less complex parts like bushing, control arm etc Smile

Memzy, just one thought.

I went out in my car with Andy Green from Hunters and the best place we found to demonstrate the knocking was going downhill on North Street in the middle of Guildford. Lumpy, uneven surface. Going uphill much less obvious.

Best

Hi Just had mine done and touch wood I think it has cured the knock. It took 2-3 attempts at the dealers to get it found and for them to agree to progress with the warranty claim. Try finding a speed hump and approaching on an angle so you go over on a diagonal with one front wheel lifting before the other. This would always create a knock when I needed it to but took me several 1000 miles to establish this. 2013 L405 AB 4.4SDV8 Luxor/Ivory, 2007 Vogue TDV8 Epson Green/Sand, 2008 Vogue TDV8 Buckingham Blue/Sand, 2003 Vogue 4.4 LPG Epsom Green/Sage, 1998 Vogue SE 4.6 LPG Epsom Green/Cream

Thanks for the tip CMJ, good to hear some of us managed to sort it out. Lets see how mine will go. I dropped the car on Friday morning and managed to replicate the knocking with master tech in the car who has acknowledged the problem.

Simon - thanks again for the North Street, it made the issue so obvious going down hill nearer TGI Fridays bend.

We agreed to have a test drive again with the master tech once they say it is fixed. I will also test the tip from CMJ

Car collected, after extensive tests i can happily say knocking is all gone. Car has been transformed it glides over the bumps and much tighter around the corners.

Lower control arms, anti roll bushes were all replaced earlier. Now they replaced both front air struts and the ARC valve block with the newly designed one as explained above.

It took me 3 visits and a lot of discussion with the workshop controller and with the master tech to sort this out. Even i printed out the technical bullettin and discussed with them. No idea why dealers are so resistant to do it.

It would be helpful to go for a drive with the master tech and point out the knocking otherwise they always come up with the usual "we dont hear any knocking sir".
