Why does pressure drop to 1 bar when it should be around 4 bar?

If so (and I admit it is an outside chance that this has occurred) releasing a pipe on the fuel rail (given it is higher than the injectors) should allow escape of any air. I'd do that if only to eliminate it as a possibility.

Problem solved (it seems to be) !
Fuel filter was clogged. In fact we think that it was fitted the wrong way. So it didn't last a lot of miles.
Could you please confirm that the upper fuel line is the one coming from the tank ?
Really happy to find a rational reason for this mess. Please note that the filter was fitted the wrong way in a Mercedes shop. Shame on them !

I don't care about the return line. At the filter area one fuel line is coming from the pump and another is going to the injectors rail. We found that the upper fuel line is the one coming from the pump. So the arrow on the filter should be top down. The old filter was fitted bottom up !Last edited by marcjero; 09-11-17, 10:51 PM.

We are all human and screw up from time to time. Most likely fuel filter support cradle was broken. Not uncommon on Smarts serviced by dealer and garages. That’s why I service all my own vehicles including sewing machines and garden machinery. Got an incredibly high reliability rate. Never any need to check the cars over before MOT except lights and check for broken springs.Last edited by tolsen; 09-11-17, 11:17 PM.
