Hello,
Please go easy as i'm new to VCDS.

I'm at work so currently have no access to my car, but i hoped id get a few tips prior to getting home tonight.

Car is a standard A4 2.0 TDI with a CAHA engine ( i believe).
Its had a hunting problem at idle for a while and i finally decided to tackle it last week. Fuel filter replacement, EGR, inlet manifold and anti shudder valve all cleaned. It went back together and was better but still not great. An engine scan gave the fault P1065 regulation discrepancy.
The fuel pressure was varying wildly at idle. I replaced the fuel pressure sensor, but no fix. then last night i replaced the N290 valve (no sign of metal on the gauze). After fitting the new valve, the car started and idled for around 5 seconds then stopped and wouldn't restart. I fitted the old valve, but still wouldn't start. I've cracked the fuel lines at each injector (with the fuel pump running via vcds) to check for fuel and bleed any air. But still the car refuses to start.

I'm stuck and would like a few pointers for me to check when i get home.

This is very frustrating, not once did I have starting issues before.

Thank you in advance.

I'm sorry, i'm at work and cant post a scan until tonight.
I scanned it last night, no fault codes were present.
Are there some checks, pressures i should check that could narrow down the fault?

I'm sorry, i'm at work and cant post a scan until tonight.
I scanned it last night, no fault codes were present.
Are there some checks, pressures i should check that could narrow down the fault?
Did you have any luck with this in the end ? I've just fitted known good injectors to a similar Audi with CAGA engine & I can't get it to start now, tried bleeding all injectors, fuel pressure is not peaking past 5400kPa on cranking - target pressure is 28000kPa, can't find anything which might be causing it, car has the P1065 code also - I have a thread on it but not getting anywhere

You could use a bit of starting fluid to help eliminate air in the pump /lines and injectors , .be careful with it , don t spray too much.
