Audi A4 not starting

Audi A4 2005 2l tdi 1705000 miles
Got in my audi a4 earlier (2005 model) turned the ignition on... nothing working on the dash apart from the handbrake light and airbag light. Crank it, starts briefly then died. Won't start, dash lights and gauges not functioning at all! now i know that if it starts then dies straight away it's usually an immobiliser issue, but why would the dash not work? long shot, but anyone had this before? i know there are a few people on here with a4's,

Is the glow plug light flashing or on constant? If flashing it could be the turbo shutting down that’s why you have no power. The ABS and traction control could be due to an ABS sensor gone but won’t know for sure until it’s plugged in.

Problema en la ECU, debe tener un corto. Inicia de repente, desaparece de ves en cuando, hasta que llega el día que queda fija.

Its solvent will dissolve the glue around the plastic plate beside the sensor...
However, on mine that glue had cracked & the solvent did clean the actual sensor, and by using its glue dissolving powers, I was able to reform the glue & reglue the plastic plate back on. The glues similar to tree sap in ways.

Sometimes I get 3 faults pop up on the dash. ESC (Stabilisation Control) , Parking Brake Fault, Drive System Fault. I sent it into a garage for testing and diagnosis, where they diagnosed the fault as malfunctioning water pump (leaking down onto camshaft intake sensor - thus throwing up the fault codes). After all this work, it was fine for around 8 months, until the fault began to come back again. I took it back to the garage who said they were unable to replicate the fault. I have tried to replicate the fault to see if there is any manner of driving that causes the fault to show up, but the… Read complete
