Hi all,
At my wits end with this odd problem I'm having on my 03/04 SL500 ABC system. I've got 39K on the clock
Started with the dreaded red warning to Drive carefully etc etc.
System had been flushed and refilled about 18 months and few miles prior. First thing then check levels which were low on the AN dipstick so filled to level
Had a period then of the warning appearing/not appearing and pools of fluid appearing under the left front wing traced to the filter/filler area on the expansion tank
A friend with the right kit cleared the messages for me and rodeo'd it and then filled to correct level again.
After running for a while the car was left and the Red warning came back and fluid ejected from same place overnight.
The ABC will raise and lower happily so long as the level is kept at a point about half of the recommended on the AN dipstick. Put any more in and it spills its guts again once you switch off.
I did notice that the seal under the filter cap had been deformed when the flush was done and I tried to refit correctly but fluid certainly comes out of there rather than the filler /dipstick
It seems that I have a functioning system apart from this and nobody near me (in the North East) seems to be able to diagnose and fix
Any thoughts recommendations on this issue greatly appreciated.
Meanwhile I dont go out without a tin of fluid!
Thanks
