UK: diesel Audi problems

Hi there, was just wondering if anyone can help me with my audi a6 c6 2.7tdi le mans. My car will start in a morning but if I turn it off it won't start again. Ive put a new battery and also had it in the garage and had 2 new injectors done. I've also had a full service done incase it might have been a dirty filter.when it starts it idles and runs fine and still got power. Also if I'm driving a long distance the esp light and glow plug lights come on. Can anybody tell me what it could be as I'm having no look with garages 🙄. I've had my old reader on it and it says there's alot of underpowered components. It doesn't stall or anything like that.

The word "underpowered" sounds like a solid clue to me. I would look at connection points for corrosion/bad connections especially those requiring a lot of current like glow plugs but not limited to them. Also, by "won't start again" do you mean it does not turn over or it just won't fire up?

It will turn over but wont fire. I've just changed the battery control monitor to see if it was that but nope.

Try a meter on your car when it's running, do you get around 14.5 Volts?

To add to the above comment, what happens when you try to restart it? Just clicks, or only cranks or nothing??

These are some of the codes off my pals obd reader. The car just cranks but if i leave it for a couple hours it will start again. But it will start straight away if i put a jump pack on the pins under the bonnet everytime.

I've changed the battery control module and that seems to have solved the esp light coming on as its not come on since I fitted it a few days ago. Where abouts am I checking for voltage on the battery or under the bonnet?
