Hello! Can someone tell me if using an oil extractor will cause any damage to the analog and digital oil sensors? I was at my local MB dealership the other day for an A service and asked what method they use to change the oil, i.e. with an oil extractor or the coventional pull the drain plug method. Their reply was that they pull the drain plug and that I should be careful should I ever use an oil extractor because it could cause some damage. Has anyone ever heard of this? Thanks, nboyer
