The other way is to alter the zcs coding to tell the car not to look for the sat nav in future (although I suspect they wouldn’t know how to do that if they can’t get past the first hurdle)
TRIKEY - In my letter to garage, I am going to use your sentence about testing ECUs individually which they could have done. Garage either lazy B. or thick B.

(What does ZCS stand for?)

You're right, it wasnt scuffed. Garage says they used the vacuum method.

Zcs translates from German ‘central coding’ the garage should be able to do it as it’s standard on T4.

Assuming they can operate T4 correctly Andy. I applaude my fellow forum members for helping lida out with this, either physically or with advice/input.

Which they have already demonstrated that they cannot.

Lida, next time you go to log in to the forums, after entering your username tick the ‘remember me’ box before entering your password and logging in.

That way your computer or phone will keep you logged in all the time and you can take as long as you need to type your posts

Internal temp gauge did not go to red, stays in middle of gauge showing that vehicle is not overheating.
Just a quick post on the above. Should the fan really be kicking in this time of year, unless sitting in stationary traffic? Are there two sensors that read temperature? Anyone with half a brain knows that temperature guages do not move quickly and lag behind the true situation.

No it shouldn't Ian, that's what the garage's Service Manager fails to understand.

No, only one. The Service Manager has not adequately explained from where he has obtained the 83˚ reading but I suspect it's from the open expansion tank which he also referred to.

Thank you REEBS, I am doing that now! It's getting thoughts together that delays me, because my typing speed is actually 75+ wpm.
