FRONT VALVE BLOCK — PORT P ONLY

WILL NOT FIT THE REAR VALVE BLOCK.

This kit repairs the line connected to port P (P as in Paul) on the FRONT ABC valve block. The rear valve block also has a port marked P, but it uses a different line. This kit does not fit the rear port P line. Confirm the valve block is at the front of the vehicle and compare the product photos before ordering.

Mercedes R230 SL500 ABC Car Killer hose repair kit

A leak in the ABC hydraulic line connected to the front valve block can turn into an expensive repair. This kit provides a factory OEM hydraulic hose and a hydraulic coupler to replace the affected hose section by coupling it to the existing line. It is designed for the line shown in our product photos.

Fitment: 2003–2006 SL500 and front valve block port P

The listed application is the 2003, 2004, 2005 and 2006 Mercedes-Benz SL500, chassis R230, with ABC (Active Body Control) suspension. Locate the line originating at the front valve block port labeled P and compare it with all four gallery photos above.

The original hose reference associated with this repair is 2309970682 / 230-997-06-82. A matching model name or an ABC warning alone does not identify the leaking line. Confirm the line location and connections before ordering.

Use our R230 SL500 ABC hydraulic line diagrams as an additional reference. If your line looks different or you are unsure about your application, contact Benz Tech Modules or call/text (818) 510-3375 before purchasing.

What comes in the kit?

  • Factory OEM hydraulic hose.
  • Hydraulic coupler for joining the replacement hose to the existing line.

This listing is for a physical hose repair kit shipped to you. Installation is performed on the vehicle; it is not a mail-in module programming service. The current kit price and stock status appear beside the Add To Cart button.

Repair overview and installation videos

The repair replaces the affected section and joins the new hose to the original line with the supplied coupler. Watch the demonstrations to understand the kit and compare your line before beginning. Access, line condition and installer experience affect the work required; the kit does not establish a fixed labor time for every vehicle.

Watch our Mercedes R230 SL500 Car Killer hydraulic hose repair update on YouTube.

ABC is a pressurized hydraulic system. Installation requires the appropriate hydraulic-system repair, depressurization, filling and bleeding procedures. Have the repair performed by someone familiar with Mercedes ABC systems.

Car Killer hose kit questions

Is this an ABC suspension hose or a brake hose?

It is an ABC suspension hydraulic hose kit for the identified R230 SL500 line. It is not a brake hose kit.

Does this kit fix every ABC leak or warning?

No. It addresses the hose section shown in the gallery, connected to port P on the front valve block. A leak elsewhere in the ABC system needs its own diagnosis and repair.

Does it fit other R230 models or model years?

This listing covers the 2003–2006 SL500 application described above. Do not assume that another R230 model or year uses the same kit. Contact us with your vehicle and line details if the application is uncertain.

Do I need to mail my original hose to you?

No. You order the hose and coupler kit for installation on the vehicle. This is a shipped parts kit.

Can I buy replacement coupler ferrules?

Yes. See the separate hydraulic coupler ferrule listing (quantity two ferrules) for the current price and availability.

How do I confirm I am ordering the right kit?

Check the vehicle application, trace the line to front valve block port P, compare the gallery photos and review the videos. If you still need help, call or text (818) 510-3375 before placing your order.

Wife’s C300 stranded her in the Costco gas station, the car suddenly failed to start! After much testing & trouble shooting I fortunately found this place!!! The ESL failed and Michael absolutely has the fix. Not only with the video’s but when you call, you get a call back! I took out the Ignition and sent it and the key and just as promised, I got them and the Emulator back, put it all in and it’s never going to happen to her again! I only gave it 5 Stars because I couldn’t do 6!

There has only been a few times I received service as excellent as this. I was able to identify the issue I was having with my Mercedes from his YouTube step by step instructions. Once I contacted him the response was immediate and informative. I mailed the part from P.A. to C.A. on Sunday and received back on Wednesday morning. As soon as I plugged it in and turned the key my car started. Through Micheals instructions he was able to help me from making a simple mistake of my steering column locking up and that would have cost thousands. Its a fantastic and great service and I am so appreciative. This was a E S L reprogram on a 2008 Mercedes C3000

This is a great shop. Run by actual people. Many sites do not list a physical address or give you any confidence that you are going to get a solution to your aging Mercedes. All problems fixed and helped through the process. Thanks MBS!

I have a 2010 ML350 that was having an intermittent starting issue. I took out the EIS (Electronic Ignition Switch) and sent it to them. I know that these issues can be expensive but they did it for a much better reasonable price. They tried a basic fix but the unit was too broken. Once I received the cloned replacement, the engine started right up but I got an anti theft lockout on the radio. I messaged them and they told me it was an issue that happens on some ML's. They paid for shipping and I quickly sent it back out. The same day they received it, a new replacement was shipped out. Within the week, I received the replacement. Just installed it and now the car is starting with no more anti theft warnings and the electronic trunk hatch is working once again! (It was not operating when the EIS was out). Was so satisfying to get it working for such a reasonable price. These guys are blessed with talent and were able to do wonders for my 2010 ML!

The service that Michael provides is so valuable. I was quoted 3500 to fix my EI/ESL and was able to fix it myself with Michaels instructions and parts for around 900 including shipping. It only took a few days to get the parts back! My Mercedes would still be sitting if this service want available. Thank you Michael!
