So all going to plan my trusty L322 tdv8 Vogue will be replaced on the driveway with a 64 plate Autobiography next week.

Very happy with the price and spec apart from one very important to me feature - no towbar!

So what are the options for retro fitting a tow bar.
Not desperate to have the retractable version or a removable one either.
Primary towing is the wife's horses so a fixed solid tow bar is a bit more reassuring.

Any recommendations for a fixed towbar to fit?

PF Jones...

Thanks i’ll look at those.

Well being friends with the garage owner helps as next week turned into 5pm today.

Managed a quick run but have noticed something we didn’t during the test drive in that it feels like something is dragging at the rear at low speeds. I’ll have a chat with the garage about it tomorrow.

Had a detachable fitted a few months back, was around £800 all in , plus another £30 odd quid for a replacement under bumper panel

So a quick update.
So far my new car experience is being ruined by warnings on the dash.
Had the transfer box problem fixed and An issue with the car going to extend height when access mode was selected.
Had it back one day and now i have a body control warning and suspension height problems again so back to the dealer we go.
Knew my l322 was too reliable and now karma is getting me!

Had similar problems with the suspension, I was initially fobbed off with a software upgrade however it turned out to be the compressor, now it’s been replaced it’s working perfectly.

do you know how the fixed the transfer box problem? I'm assuming the judder? I have this and really need to set some time aside to carry out the TSB which is a double flush of the box as far as I can tell.

The first issue with the car going into extend mode when access mode selected was apparently down to a drain valve on the compressor so suspect fixing one issue has created another as they carried out a bulletin fix on the valve. Just dropped car off so will see what they say.

Yeah, when it shoots up after a command for lowered stance that has to do with the compressors exhaust valve. It attempts to lower but cannot vent air quickly enough so it raises back up. On the l322 you'd remove the exhaust silencer and drill a small hole in it for the fix vs a new exhaust silencer which will just clog again in time. I'm sure the l405 is similar.

I'd be really curious to know what they do to your transfer box though for a repair, keep us updated.

Tell me more about this please, as I think I have this problem.

Yes in order to lower there is a brass filter on the compressor where the air discharges. If it becomes clogged air cannot leave the system quick enough and the car rises. This is what would happen on an l322 but given it is the same situation I'd imagine similar root cause. I do not know if the l405 has a similar exhaust silencer or some other component but I'd bet whatever is between air leaving the system and the atmosphere is probably the cause.

I just brought up the l405 service manual to take a look... It is different than the l322 but there are still a couple of suspension exhaust components that would cause this.

From the manual

Pilot Exhaust Valve
Attached to the air-dryer body is a solenoid operated exhaust pilot valve. This valve is opened when the air springs are to be deflated or when the system pressure needs to be reduced.
The pilot exhaust valve is connected to the air delivery gallery, downstream of the air dryer. The pilot valve, when opened, operates the slave exhaust valve, allowing air to exhaust the system.
When the solenoid is energized, pilot air moves the slave exhaust valve plunger, allowing pressurized air from the air springs and/or the reservoir to pass through the air dryer to atmosphere.
Slave Exhaust Valve
The exhaust valve operates when the pilot exhaust valve is opened, allowing air to be exhausted quickly.
The slave exhaust valve also provides the system pressure relief function which protects the air suspension system from over inflation. The valve is pneumatically operated, responding to air pressure applied to it to overcome force from its internal spring. The valve is connected into the main pressure gallery which is always subject to the system pressure available in either the air springs or the reservoir. The valve is controlled by a spring which restricts the maximum operating pressure to the specified limit.
The minimum pressure in the system is also controlled by the slave exhaust valve to ensure that, even when deflated, the air springs contain a positive pressure with respect to atmosphere. This protects the air spring by ensuring it can still 'roll' over the piston without creasing.

I'd probably start by removing these bits and ensuring they're in good condition, no corrosion, if there is a filter/silencer to clean or open it up. It sounds like this system vents via the air drier, the air drier is going to be basically a compartment full of media to extract moisture. I'd bet the drier itself is tired/contaminate and inhibiting air flow. Or some other part of the system is failing.

I have an error on my l322 about the compressor not being able to get rid of the air quickly enough. All I get is “suspension fault, standard height only”. Got - 2017 SDV8 Autobiography in Loire Blue

Yeah I saved that TSB and have the fluid for double flush on the shop bench, just need to do it. As for the reprogramming I guess if the flush doesn't remedy the issue I'll take it in for an update post flush.
