Der 8J Roadster leidet unter defekten Dachklappenservos. Die Teile sind in der Regel gut, aber Fett aus den Zahnrädern kann auf die Platine gelangen. Dies kann ein Fehlersignal erzeugen und verhindern, dass das Verdeck ordnungsgemäß funktioniert.
Es handelt sich um eine sehr einfache Reparatur, die auch bei einwandfreiem Funktionieren des Verdecks empfohlen wird, um dies in Zukunft zu verhindern.
Hey Barmy! Surprised you're not on the Audi TT UK forum. 
@ Swiss2004 - The early Mk2 TTs had a number of technical service bulletins issued against them for many of the issues I mentioned above. So you may want to look for a 2010 or later. By that time the early production issues were generally resolved. As TT-Eifel mentioned, the High Pressure Fuel Pump Cam Follower is not an issue with the 3.2, but as the 3.2 was only offered in early Mk2 production, most Mk2 TTs will not have the 3.2 engine which is why I mentioned in in the event you go with another engine.
@ Der Hausmeister Ist es möglich, eine private Nachricht an ein anderes Forumsmitglied zu senden? Wenn ja, wie wird das gemacht?
Or you could use Deepl and learn a new skill! 
@ TT-Eifel - The comment was posted in case he decides to look at another TT. Why is that a problem for you?
Hallo TTmichel63 - und mein Deutsch ist schrecklich! Ich bitte um Entschuldigung. (http://www.deepl.com)
One other thing to consider with VAG DFI engines is carbon build-up on the intake valves. This is common with all VW-Audi Direct Fuel Injected engines and will eventually have to be resolved. Walnut shell blasting is a good method, but finding a shop that can do this work can be a challenge.
When this service is performed, it's usually time to have the fuel injectors inspected, serviced or replaced.

A few things to consider on the TT you are looking at -
If you see "sport suspension" check to see if it has Audi Magnetic Ride or "Mag Ride". These are electronically controlled shocks. I have it on mine and I don't use it for daily driving. Be aware these are very expensive to replace.
The Audi head unit (Sat Nav), is called RNS-E. Audi doesn't mention it, but these were often set up to accept a Reverse Camera. The camera was never offered as an option, but if it has RFSL, it can be retrofitted. Because this is a very outdated unit, many people are replacing it with Xtron units which are Android based.
Since this is a 2007 with a VR 3.2, the timing chain tensioner may be an issue. See if there is any history of it being replaced. As mentioned above, a VCDS can be used to check for chain stretch.
Consider this is a 13-year old car you can expect some out of pocket maintenance expenses in the near future. Audi's are not cheap to own and maintain and a 3.2 is not common for Mk2. In fact it was only offered with the pre-facelift models. However since the mileage is relatively low, you should be able to get any issues resolved without too much trouble.
For both Coupes and Roadsters, typical problems to be aware of include saggy leather seats, noisy / failing window regulators, knocking steering racks, broken hood opening lever and poor (ground) connections to rear lights. There's also the risk of a broken glove box hinge if and when the damper stiffens up.
A VCDS or OBDeleven will provide some information including chain stretch, but there are a few things you will need to physically check as well -
Be aware that 2.0T TSI engines produced between 2009-2011 are prone to high oil consumption. Be sure the owner has a full service history.
The high pressure fuel pump cam follower is another issue Audi failed to mention during routine maintenance. If the cam follower fails, it can destroy the cam and will be an expensive repair. It's recommended for replacement every 25,000km.
Hole worn through cam follower results in damage to the cam lobes.
If you are looking at a Quattro, be sure the Haldex oil and filter have been changed regularly. Many service shops, including Audi, don't replace the filter because it doesn't show up on the parts list. But the Gen 2 and Gen 4 Haldex have two filters, including a small strainer on the pump.

I will be happy to do that!

Switzerland - 2007 (8J) Mk2 Audi TT 3.2 Quattro Roadster
For Mk2 (8J) Roadster owners, water behind the seats can often be traced to a blocked drip tray or if the drain tube has been disconnected inside the center bulkhead.

You may also want to replace the keyfob battery. Sometimes the signal can be too weak with an old battery - Type 2032.

I would recommend an OBDeleven to perform a fault scan to see what's wrong before you start guessing and replacing parts that may not be damaged.
If you're finding water in the trunk of a Roadster, you may want to check these places;
1. The convertible top drip trays below the roof flaps. If the drain tube is blocked or is not properly connected inside the center bulkhead, water can get into either the cabin or trunk area.
2. Rear spoiler drains. If they leak, water can get into the trunk area.
3. Antenna seal. As the Mk2 TTs continue to get older, these seals can fail.
4. Rear seal where the top meets the metal body work. Any damage along this area can result in water getting into the top storage area and from there, into the trunk.
Greetings from Switzerland! I am one of the moderators for the Audi TT UK Form and just found your website. If there are any other TT Mk2 Roadster owners who are having problems with the operation of the convertible top , we have a lot of good information we are happy to share with you.
