URGENT: Astra 1.7CDTI wont start

[NoSmokeNoPoke234]

We think its the key not sending a message to the imobiliser. How do you go about getting a new key and what details do you need to tether it to your car?

If this is the case, I had a similar issue on an 05 Asta Diesel a few years ago. I had intermittent problems with it refusing to start.

Luckily, I had bought the car from a main dealer only a few weeks before so they fixed the problem. They said it was the immobiliser issue.

I think they re-code something (I had to leave them both of my keys to fix it).

This sounds like what i have. A few weeks a go it didnt start and throught the spanner sign up and then when id try again it worked and fired up. So what did you have done to the car?

Had exactly the same. Didn't start, tried it again and it worked.

I don't know the specifics of what was done to fix it. All I know is that I had to drop it off at the dealer with both keys. Apparently it was a module of some sort relating to the immobiliser and the keys.

I had similar problems with my elderly peugeot 306 this time last year, when the weather turned that wee bit colder, a new battery solved it.

Yep thats right, but the only thing in now my car wont start at all so ill have to tow it to the garage or something. Do you know how much this roughly cost?

Do you have breakdown cover with home start?

[NoSmokeNoPoke234]

Yep ive got a recovery service with my insurance that can get me to a garage. It'll take me to my garage in yorkshire even though im in Essex currently. At least that way i know where i stand with the garage and wont get ripped off

Make sure they have appropriate diagnostic equipment before you have the car taken there, lots of smaller garages do nowadays but without it, you're going to waste a trip.

I don't know if the breakdown people have stuff like that these days to get people going when there's silly electrical faults stopping a car from starting....

[NoSmokeNoPoke234]

Tbh the garage i go to is small but pretty big time at the same time, and the recovery service im using i only them to get me home. which they will

[NoSmokeNoPoke234]

The problems been resolved. Although checking everything through, when the breakdown guy came he reset the ecu. and then when he multimetered the battery it came up with 12.02 volts. I thought this was perfevt however he said all cars need 12.03 (Bit sceptical about this but i went with him). With a battery booster on it, she fired right up. Although it was annoying it was that, im glad it wasnt anything more expencive.

Well that's a meaningless test. I'd have thought any battery would be a bit down on volts after you'd been trying to start and then left it for a bit. More important would be to check what the volts are during cranking. Not that most 'mechanics' "don't do" electrics....
Low battery can cause a myriad of problems, especially with modern stuff. I connected my Op-com to a Signum (10 years old) and it took a while to connect to the 7 ECUS around the car! Scary.

Anyway, glad you got it sorted.

Good result OP; nice to see a newbie-asking-for-help thread go well on here for a change.
