One of our Audi TT Forum members has been experiencing problems with his convertible top operation. I recommended that he purchase a VCDS (which he did) as the Roof Flap Servos (RFS) are generally responsible for 95% of convertible top failures. Sure enough, he came back with this and two other Address-26 (Auto Roof) faults shown below -

03246 - Sensor for Canopy Flap Left (G596)
008 - Implausible Signal - Intermittent

As I have for many Mk2 Roadster owners, I recommended that he remove both the left and right RFS, clean out the excess grease that tends to migrate onto the internal PCB then reinstall them and use his VCDS to run the Roof Flap Adaptation.

• [Select]
• [26 - Auto Roof]
• [Output Tests - 03]
• [Select] Selective Output Tests
• [Choose]Convertible Top Flap Initialization
• [Start]


Oddly, it came back with this message "Refused by Control Module" which I have never seen before.

Any idea what would cause this?

Note - the other two faults; 02000 & 01097 are not unexpected since the controller lock out automatic mode and these will clear once the Adaptation has been performed.

FYI this was a common problem on those cars. Make sure you have the updated part number. Should have A on the end. Otherwise your wasting your time.

@ Uwe - Auto-Scan forthcoming...

@ EuroX - Not a waste of time at all. This has worked on Mk2 Roadsters going back to my 2007 and think even a 2013 owner was able to do this repair too. In some cases, intermittent operation has been resolved doing this without an Adaptation when no faults from either RFS has been logged. The RFS clean and VCDS Adaption has proven successful almost 100% of the time.

They are a known problem. Most of the time as long as you set the gap correctly to 10MM they will work for some time. Sorry I rather not waste my time and purchase the correct updated parts and never have the issue again.

@ EuroX - When you say "...set the gap correctly to 10MM they will work for some time." What gap are you referring to?

Gap between electric windscreen edge and convertible top flaps in the up position. It needs to be 10mm or bigger.

Seems this was due to the user trying to run this test without the engine running so he ended up draining his battery.
I advised him to try it again with the engine running and everything worked out okay.

Good point on the 10mm gap.

However if the copper contacts of the potentiometer are fouled with grease, this can lead to the expected range for G596 & G597 being exceeded and it will register a fault.
That's why it's important to clean the grease off the contacts inside the RFS.
Whether this is an OEM factory fitted RFS or a replacement, the presence of excess grease in the potentiometer contacts can cause this problem.

Here's the auto-scan. As noted, there are a lot of low/under voltage faults, so the battery is suspect.

The owner has also gone through and checked the ground points, paying particular attention to the two below the air filter as these often get corroded.

But so far nothing has improved. So new battery in next.
