Hi all,

Apologies if this thread already exists but I am having issues searching the forum for specific threads (!).

Last week my 1.6 2006 Astra Design cut out suddenly and now does not start (engine turns / clicks when turning ignition but will not start). It is the first time it has cut out. AA could not diagnose the issue; my mechanics 'think' it is the ECU as there is no communication between the diagnostics machine and car. Frustrating as it would appear they either don't know what the issue is or simply don't want to take liability. Emission control system fault, oil pressure warning and charging system warning lights all appear[ed] on the dash.

Are these signs of an ECU fault (online research suggests it is)?. I need the car up and running asap as I go to uni in less than a week now - I have been quoted £295 for a replacement ECU including labour - does this sound right? As the garage cannot confirm it is the ECU I have been reluctant thus far to do anything but if I get the general consensus it is the ECU then happy to proceed and have it replaced.

Thanks!

Chetan

did anyone check the fuses to ecm and diagnostic connector ?
Not that I'm aware of - I myself haven't and mechanics have told me they checked cambelt, as fuel pumps / injectors and engine compression (all seemed fine). Beyond that I can't get anymore out of them.

Need someone with TECH II to check the car.
The generic OBDII tester the AA use is not enough to correctly interrogate the cars ECU's.

If it suddenly cut out and was fine up until that point. And now it turns over but does not even try to start ?.
To me that says "Direct Ignition cartridge".

Thanks for the reply! I had a Vauxhall specialist come down and run diagnostics - on the computer the only irregularity pointed to Crankshaft sensor. He also connected a new ECU and same issues, and also looked for damage within the engine, including the direct ignition cartridge. I've had the crankshaft sensor replaced today and still not starting. Now the garage say there is engine damage so best thing to do is scrap it. I can't really afford to replace the engine part by part until it starts - unless there's an oversight and simple fix it may be time to say goodbye!

Was it a cheap sensor? Always best going for genuine as Astras don’t seem to like the cheap ones

The cars don’t like non Vauxhall’s parts when it comes to sensors
