According to VW, the CT 1044 is necessary from a certain engine number, depending on the engine code. VW has increased the change intervals as of that point. The CT 1044 can however also be used for all the older TDI engines. The OEM number is 038109119M.
The CT 945 is required for applications subject to higher loads, such as all Sharan, Galaxy and Alhambra models. However, the CT 945 can always be used instead of the CT 867 (but not vice versa). The OEM number is 028109119AA.
The corresponding type of engine is factory fitted with a belt similar to CT 849 (152 teeth, OEM number 058109119D). According to VW/Audi documentation, the thermal damper has to be exchanged for a hydraulic damper when the timing belt is changed. This replacement requires a different timing belt called a CT 919 (153 teeth, OEM number 058109119C). This means that an upgrade kit is required, containing the changed belt, a pulley and damper.
We always carefully research these details using the manufacturer's specifications. However, we would advise you to carefully check the removed parts for any differences and, if necessary, to contact the ContiTech hotline at +49 511 938-5178 to discuss the matter.
The "lifetime belt" described in some press reports is not intended for retrofitting vehicles already on the market. This is because the modified timing belt also requires modified engine control components (camshafts, oval sprocket technology, pulleys, bearings, etc.). As a result, no retrofitting is possible here. However, for some time now there have been vehicles on the market for which the manufacturer does not provide any change recommendations. Instead, a test mode is required that allows a trained mechanic to decide on the replacement.
For final consumers there is a warranty period of two years. In all other respects, the statutory regulations apply.
No, the kits are numbered chronologically on the basis of when they were introduced. The K2 kit, for example, may contain just one pulley. Refer to the symbol on the packaging for information on what the kit contains and/or check the contents and user advice indicated in the catalog.
Elastic multi V-belts can easily be stretched during installation in order to establish the required belt tension, therefore it is not possible to install normal multi V-belts as an alternative.
Performing a proper belt change usually involves more than a belt alone. Workshops play it safe if they also renew the tension, idler or guide pulleys at the same time as changing the belt. The kits from ContiTech give the workshop a complete package containing a full set of matching parts for performing the installation properly. This guarantees the best possible quality and safety for a technically proficient and effective timing belt change.
The kits contain different contents for different vehicle applications, for example because the vehicle manufacturer has made changes to the belt drive (e.g. automatic instead of manual tension pulleys introduced from a particular model year onwards).

Intervals specified by the vehicle manufacturer must always be complied with. If the vehicle manufacturer increases the interval between belt changes due to a new type of belt, and this change is also valid retrospectively for older vehicle models, the km increase can also be applied in the case of the corresponding CT belts (check OEM number!).
As a rule the change intervals indicated are the manufacturer recommendations. As belts are used to a certain extent in different vehicles and exposed to varying load conditions, ContiTech cannot say anything definite for a specific belt type. In any case, the manufacturer recommendations concerning change intervals for a given vehicle also apply to ContiTech belts.
Leakage occurring at a later date can significantly impair the function of the belt and the automatic pulleys, even leading to total failure.
This can be roughly assessed by simply rotating the bearing by hand. As a rule the parts have been in use at least since the last belt change. Replacement is always advisable as subsequent replacement or a related failure always entails a considerable cost.
Even if a timing belt appears to be in good condition, years of use under constantly changing temperatures can cause severe aging and considerable engine damage could result if the belt tears suddenly.
The tension is a crucial factor in attaining the normal change interval. Insufficient tension overtaxes the teeth and can cause the belt to fail as a result of torn teeth. Excessively high tension is usually indicated by a typical sound while the belt is running and can usually be corrected in time before failure occurs due to overload. Incorrect alignment of the belt drive can cause the belt to chafe sideward against a flanged pulley or covering. This will lead to corresponding wear and eventually cause premature failure (belt rupture due to insufficient width).
There is an increasing tendency to use technically elaborate components for accessory drives. These parts are also subject to wear. Here it is particularly important to check for any cracking on the decoupled torsional vibration damper ? if such exists ? and to also check the proper functioning of the alternator freewheel clutch ? likewise if such exists.
The BTT Hz is basically intended for tension pulleys that are adjusted manually. Multi V-belt drives can now also be measured. A data manual provided with the gauge gives clear information on the settings ? in the frequency unit Hz ? for all of the most common vehicles.
An application list for specific vehicles can be found in the handbook and is also available here as a download from the Internet.
No, the handbook is only available in conjunction with the belt tension tester.
No, force measurements cannot be converted into frequencies. We therefore recommend buying the BTT Hz so that a modern tension measuring method is assured using the parameter of frequency.
The device is self-calibrating. This can be done by any user with reference to the instructions provided with the product.

Element types B, C/E and the timing belt basket can be combined as required, and attached to the display frame with base. The V-belt/ multi V-belt hanger type A is only suitable for mounting on walls.
