Since joining this forum I have had a few problems with my two Mercs. Each time I have searched the forum for help via previous posts and every time I have been pointed in right direction. Have prob saved well over £1000 by diagnosing and then buying parts myself. Well done to all contributors!!! Prior to joining I spent nearly 3K at stealers on problems for which parts cost £800. All were seemingly common problems though at time how was I to know....
