Re: Technical Safety Bulletins - Discussion
All bulletins now posted.
Just a few typos to sort where Opel docs have been poorly translated to English for "Vauxhall sales make"
There are a few duplications where a
field remedy / TSB appears in two sections.

Re: Technical Safety Bulletins - Discussion
I am sure that there was a factory recall on our 1994 C18NZ LSi hatchback for the hand-brake.
(Small block front callipers and rear drum brakes.)
-------------------------------------------
Returning to Field Remedies.
Affecting the C20NE.
There is no mention of the slow rpm "wobbly" idle.
Complaint:
Engine idles at approx. 650 rpm
Remedy:
Initial issues were sorted by dealership technicians increasing the base rpm using the Vetronix Mastertech Tech1 / 1a hand held programmer.
Alternative remedy is to fit a Yellow Octane Coding Plug.
Yellow coding plug increases the idle by 100 rpm.
Part No = 90241963 /
Opel Kat Code = 12 86 527
----------------------------------
Complaint:
Erratic Idle. (Hot Engine).
Unplugging Idle Control Valve electrical connector increases the rpm significantly.
Cause:
Gummed up / sticking Idle Control Valve in conjunction with an oiled up breather system.
Remedy:
Clean or Replace Idle Control Valve.
And clean the breather pipes and gauze filter in the camshaft casing cover.
