I bought a used GTC! - Fantastic car but a few issues i could do with advice about

[Mattymush]

your 100% be better of with an MDI and GDS2 (main dealer level software and interface) but the cost of this isn't worth it.

The next option is an OP-com I recommend you buy from the link below, you can get it cheaper on ebay etc but low quality units etc.

Please note the op-com is still very limited on the Astra-J/GTC so don't really expect much other than reading and clearing fault codes.

Hey Rusty! 

I have an updated.

I got the error codes to read when I sent the car to get its air-con working (all working now). 

got three codes:

p0069 - manifold pressure - not a big deal I'm told. 

p0580 - this is the cruise control  - not overly concerned about this one. Garage thinks it would be a lot of work to fix/find the fault. 

b0957 - which is an error for the front right corner parking sensor, and my main concern.

Here's what I need some advice one.....


I bought a new parking sensor and swapped it over and still the system does not work, same "service parking assist" warning as before. 

 I did look at the middle right parking sensor, and interestingly the sensor has been glued directly onto the wire (see photo). There should be a female attachment that the sensor locks into but it is gone. 

I'm wondering if the problem is connected, do you/anyone have any ideas, or routes to go down to find the issue.
