The E53 is doing daily duty ferrying the kids around town for summer activities and shopping. So, to address the slight roughness that INPA showed, I replaced the MAF with a Pierburg that I bought on Amazon. Runs smoother and, I hope, a little quicker.

Since mid-May the SES light has been on. There were two codes, one for the aux fan and one for the tank vent. Aux fan was solved by cleaning the connector and putting some dielectric grease. Ordered a new gas cap from FCP which, very promptly, fixed the tank vent code.

Next is replacing the o-rings on the fuel injectors. I also got the top rubber insert for the windscreen as replacing the glass, that has been cracked since 08 or 09, should really be replaced soon.
