I have a 2005 C55one owner with only 75,000 miles, I purchased it damaged and was hit in right rear fender/door, got it at a great price. Repaired it and had to fit new door right airbag and a few suspension parts. When we hook up to clear SRS light it shows the following;
R12/6 left rear ETR ignition squib is to high also shows
R12/1 drivers ETR ignition squib is to high.
Are these the seat belt tensioners, if so does anybody know what the part numbers are. Thanks
