Another roof query... sorry

[Chippie]

That’s definitely a job that needed doing

[t90ark]

And after cleaning the motor out.... still the red light, the bong and 'roof movement impaired'.

Anybody know a roof person near Southampton?

[t90ark]

So, in case anybody has any thoughts.... cos I don't, lol, this is what happens when I try to open the roof.

Press button, red light and bong, message on idrive 'roof movement impaired'.

Nothing attempts to move, not the windows, not the roof.

Could it be the much talked about salmon relays?

[Chippie]

Unlikely to be the relays as when they fail they stick and the pump motor just keeps running until it burns out, it’s more likely to be a micro switch or hall sensor that’s failed or possibly a broken wire where they bend around the roof pivot points. Have you scanned the car again after putting it all back together?

I've just checked and roof related, I still have A6A3. I also have center roof A670.

Have a read of this post

Looks like it could need a new motor.

I've just checked and roof related, I still have A6A3. I also have center roof A670.

So the roof won't move due to the fatal error in the pump sensor..the other code appears to be more climate control related

But what is interesting though, if I move the car, it'll most likely work. Strange.

Its a very very quirky system with many undocumented 'features'...mine won't open on the fobs now but opens on the buttons..no errors..no logic..go figure..the CTM module that controls it is not very bright..so error diagnostics are poor..substitution is often the key strategy..

If that is the case, then chances are you have a damaged, but not broken, wire somewhere. Making a circuit sometimes but not always.

Even though it worked fine before it sat up over winter? I'm not fortunate enough to have a garage so it lives outside, lol. I kind of feel it's damp, corrosion related.

I'd be ecstatic to be wrong, though, lol.

Thanks for the comments everyone. Chucked this on and she breaths again, lol.

Until the next time...
