I’m on my 2nd fuel filter this week, was getting a bit of black smoke out of the exhaust so dumped injector cleaner directly into the old one and revved the stones off it . Big clouds of black smoke! Then changed the fuel filter for a fresh Bosch one and exhaust is back to normal now.
I had a spare intake so I took the two sensors from that fuel rail and swapped those along with a Mann 6.6 bar fuel filter onto the car. Started the car and it turned on and ran wonderful (so it seemed).
Fuel filter! I had the same on K9K 1.5 60kw
Fuel filter connectors or the filter itself is the issue, 100% confirmed it on my car.
Since my car is 2003 i found out that Delphi filter is a proper one as it has some sort of mechanism inside which is built properly unlike other brands such as Kamoka or Filtron.
Not sure what the thing inside is called but overall Delphi has OEM specs for the connectors and the rest.
Brand new Mahle fuel filter
I’m going with genuine BMW hoses and MAHLE fuel filter hoping this time it lasts and nothing rips
I just grabbed the duralast filter from AutoZone, I think it’s part number FF655DL. It was identical to what was already in my truck. Can’t say if it’s the best option or not but I’ve had no issues!
Wix is only $2 cheaper on rockauto. $28 vs $30.
Ran a bottle of it through once, saw no difference.
I removed the Meyle filter. There was no rust inside, nor in the fittings, luckily. The shell was heavily corroded. Edit: There was a corrosion in the fitting, on the rib where clip holds, not inside of a fuel part.
I bought a new set of Meyle rubber bushings for control arms, waiting to be installed. Not yet but soon (but MOT pass last month). Also I bought a Meyle fuel filter 5-6 years ago, to replace the OE aluminium fuel filter that developed corrosion in the fitting. Meyle fuel filter is made out of steel and rusts like crazy under the car.
