Looking at replacing the oil filter and coolant gaskets, are Elring OEM quality, or would febi bilstien be better, or is there any other brands I should be looking at
I believe the tensioner is INA from BMW, but what about the belt?
Febi have been hit and miss for me for other things. I've used Elring for other gaskets in the past but for this job, because it's such a PITA, just buy OE and do it once.
I got tensioners and pulleys from INA, Dayco belt. Though I think Conti are the OEM.
I must have used Autodoc 20 or 30 times. Most recent boxful arrived last Friday, in fact. They did once annoy me by substituting their own brand stuff for the brand I'd ordered and trying to persuade me it was just as good, but every other time they've been good.
