Hi fellow owners, can someone please show or guide me to the light at the end of the tunnel. I have an 04 1.4 tdci that refuses to start. I initially had a leaking leakoff pipe I repaired it with new R clips rebuilt the covers etc but now the engine will not start have had to recharge battery twice trying to start, turns over great but not even a cough. Could I have damaged the injector loom as I only pulled it out of the way and not removed it. Or could it be the immobiliser as I used the Blue Master key instead of the key fob remote. I had read somewhere that it can play havoc with immobiliser. I did try to recode the key in the ignition turning it on and off quickly till it beebed then pressed both buttons. I thought about getting an ELM327 cable can someone confirm mine is OBD2.

Waiting with baited breath in anticipation.

Had car checked out the engine ecu is dead computer will not talk to it, all other electrics and mechanics are fine. My question is if I buy a 2nd hand unit from a reputable dismantler and purchase the engine ecu with the central locking ecu with induction coil for the ignition and a key fob matched set will I be able to fit it to my car without any programming and will I need the instrument cluster as well. My engine ecu is a Seimens 3S61-12A650-LB 5WS40140D-T (SID 804)

thanks in advance

Have you checked ECU fuse and supply?

Might pay to get an auto sparky on it
