well lads, I know this is an old thead but this seems to be the only place with good information on the 16 valve. I have a 190 2.5 16valve and just have a few questions. when i bought the car nearly 3 years ago the hydraulic rear shocks had been replaced with spax shortened shocks and springs all round but my asd system doesnt work now either. theres nothing wrong with the diff itself and the pump is stil on the head, from what iv been told the asd and the sls both run off that pump so im wondering is it possible for the asd to work when the shocks have been changed to manual or what else could be wrong.?????? also is there anywhere i can get poly bushes for thic car. any help would be geat thanks....
