Hi,

 

from my point of view, you have to check:

 

- defect code memory

- diesel filter

- fuel pump (near cylinder head)

- glow plugs

 

regards

"defect code memory" = read the error codes. Do you have access to VAG-specific diagnostic tools or at least a ODB2 compatible reader?

[yllilepaja]

Yes i have read the error codes but nothing evry thing okay fuel fillter i have replacet yesterday fuel pump okey

[herr_tichy]

When replacing the fuel filter, the casing can crack easily. The crack isn't always very visible, but allows air into the fuel system over night. That would explain why the issues only occur in the morning.

But the funiest thing is wen it starts i have no more problems all day till next morning the battery is new with 100 mah and one boost with 30%

As I said, check for hair fractures in the diesel filter housing. Takes a few hours for enough air to seep in to become problematic.

Okey ill check that thank you very much but did you now does it have a fuel pump in the tank

[yllilepaja]

It is 1.4 tdi 55kw 2005

I don't drive a TDI, so I'm not sure, but as far as I remember, unlike the bigger VW/Audi TDIs they don't have a pump in the fuel tank, only the one one on the engine block. This is why air in the system is such a problem, the pump then runs dry and has trouble generating enough vacuum to pull diesel from the tank.

 

Official documentation says there actually IS a fuel pump in the tank, but that is not correct - maybe one of our diesel drivers could confirm this?

Thank you very much for the help

No pump in the fuel tank. Pump in front generates vacuum and pulls the diesel from the tank. Check the diesel filter housing, it often cracks when changing the filter. These cracks can be very small but big enough for air to get into the fuel system.
