mastacrx Posted February 19, 2020 Report Share Posted February 19, 2020 Does anyone habe similar noise when idling? Tensioner? Rod bearing? Sounds is coming from the bottom vanos or disa area. Cheers Matt Quote Link to comment Share on other sites More sharing options...

Schumacher Posted July 20, 2020 Report Share Posted July 20, 2020 Did you replace it with an OE or aftermarket unit? I've found the aftermarket ones just don't last. Quote Link to comment Share on other sites More sharing options...
mastacrx Posted July 20, 2020 Author Report Share Posted July 20, 2020 Aftermarket. It was SKF one. Quote Link to comment Share on other sites More sharing options...
Schumacher Posted July 20, 2020 Report Share Posted July 20, 2020 SKFs have a plastic/composite impeller so it should be ok? Fitted a Kolbenschmidt from C3 BMW, lasted ~23k miles before it failed. Then fitted a Meyle, that failed too. It's the ones with a metal impeller that wear out the bearing causing premature failure. Nidec GPM and Saleri (OE for Ferrari) are OE suppliers to BMW. Nidec only sell direct to BMW so bought a Saleri with a composite impeller. Quote Link to comment Share on other sites More sharing options...
mastacrx Posted July 21, 2020 Author Report Share Posted July 21, 2020 In my previous E39 I fitted one with the metal impeller and the bearing failed after 40 000 miles. Can't remember the make tbh. I know SKF does good bearings though. Quote Link to comment Share on other sites More sharing options...
Schumacher Posted July 22, 2020 Report Share Posted July 22, 2020 Hopefully the SKF will be ok. I just got tired of changing mine hence why I went OE. mastacrx 1 Quote Link to comment Share on other sites More sharing options...
