Fuel filter Mann or Bosch
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.
Pros: exhaust back to normal
Cons: black smoke out of exhaust
Vehicle:
Skoda Octavia
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).
Pros: ran wonderful
Vehicle:
Volkswagen
I use Mann filter. They're trustworthy and not very expensive either
Pros: trustworthy, inexpensive

I am a sucker for Mann so I bought it. Took out the old filter, and no fuel coming from inside the filter. Slammed it couple of times and finally the fuel came out, black. It’s literally like black coffee coming out from the filter. Installed the new fuel filter, and cranked the car couple of time to let the fuel pumped to the engine. And finally it starts, but it misfired here and there. Crank it couple more times and it starts normally. The idle is absolutely silky smooth. And the performance improved a lot.
Pros: silky smooth idle, improved performance
Cons: misfired here and there

VDO is OE and can be got for €120~. Get a fuel filter for €15 from Bosch, part of your maintenance anyway.
Pros: affordable price, easy maintenance
Recently, (about 2 weeks ago) I did a new fuel filter, new spark plugs, new plug wires, new distributor rotor and cap.
Mann from ECS for me. Every other filter change I pull what fuel is left in the housing, refill with your diesel treatment of choice and then prime. For me it’s just a bit of extra lube for the pump on my ‘14 JSW. When I skip this step I don’t prime and never had an issue.
Pros: easy to install, no issues
Vehicle:
Volkswagen
Bosch is not as good as it used to be because they want to get into the DIY market. As far as their fuel filters, I do not think you will go wrong.
Pros: fuel filters are okay
Cons: not as good as it used to be
The best would be OEM. But Mann is what I used to replace mine. Didn\u2019t feel any difference though and I had about 108k on my car.
Cons: didn't feel any difference
Mileage: 108000 km
I opened the Fuel Filter Housing up and noticed the Bosch Fairy had stopped by and littered my system with metal fairy dust. I dropped a magnet into the housing and pulled out plenty of extremely fine metal dust.
Pros: easy to check
Cons: metal dust in system
