Hi all, so might rear drives side has started to sag when standing on my R230. While at PCS it was discovered that the rear ABC valve block appears to be weeping. Having replaced the front valve block last year, I’d rather avoid paying C£1.5k again and discovered that there is a rebuild kit...

So, I sold the SL55 -- I wanted to keep it forever but reliability worried me and I needed the cash for an investment (which is currently paying off, hence my new questions) I am now daydreaming of an R231 early SL500, or possibly the SL63 - But the first question my wife asks, what about the...

Hi. Am currently replacing the seals & O rings on my ABC tandem pump. Have taken one of the 7 Allen bolts out that hold the spring & piston in. The bolts thread has broken in two for some reason. The other six bolts are fine. Does anyone know if the bolt cap can be purchased individually?

Hi folks, I have a 2001 CL500 and I recently had the red ABC warning light. I took it to Mercedes and they charged an hours labour for diagnostics. They came back to me and said the ABC control module blew up. They even showed me a picture of a burned terminal. They wanted 1500 euro for parts...

The left rear strut on My 2004 SL55 has suddenly become inoperative. Driving the car on Thursday and got a "grey" ABC fault "visit workshop" message, drove 10 miles to get home and could feel no difference with ride/handling. Switched off engine whilst moving cars to park it and when restarted...

Hi, Wondering if anyone could help me. I have a 2000 Cl500 W215. On friday i got a puncture in the near side front tyre. Went to change the tyre and it appears that a bolt from the suspension control arm has dug into the tyre and cut through the entire tyre as it has been rotating...

I recently suffered a bad leak on my rear suspension, first noticed when spotted hydraulic oil sprayed over rear wheel. eventually it went altogether and sank down on that corner. when I eventually got it home, I found that it was leaking from the a corroded section of rigid steel pipe inside...

Mods, please move this to DIY section... OK Chaps, so after much poking around it has been determined that my wagon needs the front ABC valve block stripped out and cleaned due to gunk buildup. I've asked for it to be rebuilt as well- new O-rings and spacers- and in order to do this have...

I have just got my car (SL500 r230 2003) back from a Independent garage that has replaced the transmission control. On my second day of driving it i got the dreaded ABC red drive carefully message. I have just checked the ABC fluid (See picture 1) and it appears to be below the top two notches...

Hi guys. I'm having some issues since the pump change and could do with some pointers please. I've just bought an iCarsoft i980 to allow me to clear and read codes and values. On turning the engine on I will usually get a red "drive carefully" with system pressure reading 4 bar. There is...

Hi, I was in Park with the car running and noticed that it slowly raised it suspension up to maximum height. It then suddenly went back to the lowest setting, and the cycle started again. All four corners are doing the same. I switched off the car. Waited half hour and tried again. The...

My car (C216 CL500) developed a loud drone/ humming noise (engine speed correlated) over the weekend, Mercedes Mobilo came out and the technician said it's highly likely to be the pulsation damper by the ABC pump or a pipe that is touching the bodywork hence making the noise/vibration. He'd...
