Clk w209 270 diesel starting problem

[cyberj]

Evening all,

Had to replace crankshaft sensor recently due to the car dying and also the cam sensor but even before that the car was getting harder to start, it turns over but takes now about 4 seconds to fire up. I'm hoping it's a fuel filter replacement but cannot find anywhere where it's located. I have searched on the forum but nothing coming up, maybe it's my phone and also no fault codes on icarsoft , battery is fine and I'm not very mechanically minded so any help appreciated, thanks

Probably (again one more) air ingress caused by hardened o-rings/brittle low pressure lines. Lotsa info by search. Then injectors may leak too much to tank line and pressure in not rising up fast enough. But if you can't find a fuel filter in engine bay, I would let some indy do all checks needed...
