I own a CLA, but here to talk about a truck (Mercedes Actros MP4).......work truck. We use a mobile service/repair guy who informs me that Mercedes recently published a "Service Measure" advising to replace the Sachs Kit (3400700531) with a Valeo kit (827521 or 827522) due to issues with the Sachs disc. He doesn't have this "Service Measure", but swears he saw it within the last 'couple of months' - much like work life balance and the Loch Ness Monster. Has anyone else heard or seen anything similar? We are due to replace the Sachs clutch on two trucks and we would do a like for like replacement. However, if they are recommending a different manufacturer, I would be inclined to do that. Sorry if this is not the place to post this, looked around for a truck thread but didn't find one.
