The Problem
Vehicle sags on one or more corner after shut off.
The ABC system on Mercedes Benz vehicles is a computer controlled hydraulic system, the system adds / removes fluid from the struts, the objective being to keep the chassis level at all times. This is a great system when fully functional.
A common failure point of this system is the valve blocks. This manifest itself as one or more corners of the vehicle sagging or lowering when the vehicle is parked after a few hours or days (longer term sagging isn’t necessary cause for concern). Or one or more corner raising shortly after vehicle shut off.
The valve block fails to make a good seal allowing fluid to escape the strut and return to the reservoir leading to the corner sagging. This failure to seal is more often than not caused by the O-rings deteriorating within the valve block solenoids, most likely the locking valve.
There are two valve blocks on each vehicle. One controls the front struts the other the rear. Each valve block has two locking valves and two control valves. The locking valve locks the level of the strut once the vehicle is turned off.
If any residue is stuck in the solenoid the plunger will not seal correctly and strut fluid will be lost resulting in that corner of the car sagging. Such residue is normally caused by the original O-rings deteriorating. Alongside the O-rings are backup rings to maintain the shape of the O-rings under pressure. Some valve block solenoids are fitted with nitrile back up rings, like the nitrile O-rings these deteriorate and can clog the plunger.
Symptoms of the fault
Car sagged, dropped, lower, down, lowered, at one or more corner after short period of time after vehicle shut off. Vehicle raised at one corner after shutting off. Common fault codes: “Too Low” warning on dash, C1525-001, C1525-002, C1525-004 or C1525-00.

In around 2007 the design of the valve block changed, our repair kit fits the design previous to the change in 2007. The later valves don’t tend to fail in the same way. If your valve block has been changed in its life it is possible it was changed to the newer version. To determine this the ABC pump can be inspected on the upper right side of the engine; If a black sphere is attached to the pump it is the 2007+ model.

Our solution
A full overhaul kit to repair the ABC valve, constructed of the finest materials to last the life of the vehicle.
Our complete overhaul kit includes all components required to restore the valve block. Our kit is for one valve block.
Our kit includes:
Replacement O-rings to replace original O-rings on the valve block solenoids. Our O-rings are constructed of Viton a vastly improved material suited to the fitting environment so will not deteriorate like the original part. Resolving existing faults and stopping them reoccurring.
Replacement support rings, these are constructed of PTFE to last the life of the vehicle. These replace the original nitrile support rings which if fitted to the valves tend to wear and cause issues. Our rings are a split design allowing easy install.
Replacement solenoid retaining clips x2, more often than not the originals snap when removing, we include x2 replacements to allow easy repair.
Replacement weather seals for the control valves. The original seals tend to deteriorate and are often damaged when removing the valves. Others try to seal this stacking O-rings we don’t believe this is the best solution so have moulded replacement seals to ensure a weather tight seal.
All components are labelled for easy install. Please check out our picture instructions and videos to see our comprehensive repair kit in action. Designed and engineered to resolve ABC valve faults for the life of the vehicle.
You will receive
14x Viton O-rings
14x PTFE split design support rings
2x Replacement valve retaining clips
2x Weather seals for control valves
4x Stickers to mark valve positions
This allows repair of 1 valve block, front or rear. If you wish to repair front and rear you will need two kits. - Авто та транспорт
The SL55 or other ABC cars get such a bad rap for expensive maintenance and repairs of the suspension system. If you have some mechanical skills and good source of parts at wholesale pricing, it is not really not that bad. When a side sags or the system springs a leak, most faint thinking OMG there goes thousands of dollars! The two valve blocks are some of the most expensive parts to replace at a dealership. This kit only cost less than $100 and rebuilding it yourself saves you thousands! The moral of the story is if you can't afford the upkeep of a used $120K+ Mercedes, don't freaking buy one. If you do, be ready and have cash saved up, otherwise don't bad mouth your dismal experience because you assumed the car would be like a Toyota.
It’s accurate apart from the fact the solenoids are quite tricky to get out. I carefully put them in a vice with soft jaws. Then tap the aluminium manifold with a large punch to remove them. I also used letter punches to stamp the manifold a b c d than put labels on the solenoids and take pictures of orientations. You have to use a pair of water pump pliers carefully to turn the solenoids.
Thank you for the good video.
Thanks for watching!
Nice video! subscribed.
Thanks for the sub!
Well I whish I was clever for I 've bought both front and rear , refurbished they are just under $400 . but at the dealer they are $2000 . I bought refurbished and hope they work , that's is expensive enough then there is the replacement cost . But you can get it any ware . Thank you
Great products. Pity the phone enquiry line is always engaged!!

Can I use alcohol or water to clean the valve block or is that a bad idea. Also is there anywhere to get the springs if mine are not firm anymore
Конкретно.
Pls this for 2002 models !
03 s55 amg abc light is on red no sag or leaks do you think this will help my issue?
It might. I recommend you get or borrow a STAT diagnostic system. Red light ABC warnings can be caused by many many things. But, yes, sagging is usually caused by failed o rings not allowing the system to keep pressure to hold up that heavy car.
Red light could also mean low ABC pressure in the system. Which could mean the pump is failing

Al Mad since I’m faced with doing this job I’d like to know what is wrong with their description. I don’t want to screw this job up! Thanks.
@@robertlaugherty4914 me too!!!!!
there are 2 different blocks, one in the front and one in the rear... they are similar enough that the service should be similar
@@bknobb4802 save yourself a lot of time and money. Just find a Benz part house and they will sell it rebuilt for 500
