Risk of mixing up the tensioner and deflection pulleys

Risk of mixing up the tensioner and deflection pulleys in the CT1038K1 and CT1038K2 kits during fitting Problem: The deflection and tensioner pulleys are mixed up during fitting, resulting in incorrect tensioning. This can lead to increased noise and even engine damage. Cause: The two pulleys look almost identical with only a small difference in diameter. As a result, it is easy to mix up the two pulleys. Solution: The deflection pulley V55826 has a diameter of 67mm. The tensioner pulley V55822 has a smaller diameter of 63.7mm.

Get to know your vehicle warning lights

With the increasing electronic content in modern vehicles comes a multitude of new dashboard warning lights. And since cars can now effectively self-diagnose, these lights will communicate important error messages and faults, alongside less critical information. Worryingly, however, a recent survey suggested that nearly half of all motorists don’t understand what they mean. Do you? Here, we provide a quick overview of the most important lights and explain why you should never ignore them. Some warning lights aren’t cause for concern; they’ll simply go out once the car’s running. Others are a sign, usually the first sign, that something’s not...

Cooling system cannot be bled properly on vehicles with an electrically/pneumatically controlled water pump

Examples: Audi / Seat / Skoda / VW 1.4l, 1.6l, 2.0l TDI - CT1168WP1 Problem: Noise or temperature problems as a result of incorrectly bled cooling system. There is still air in the system following replacement of the electrically/pneumatically controlled water pump. Cause: On vehicles with an electrically/pneumatically controlled water pump, the cooling system must be bled after being refilled using our vacuum filling device (Tool Box W01) and an additional diagnostic device with the necessary functionality. The reason for this is the thermal management system, which has additional valves that supply different heating circuits. The valves need to be...

Caution V Common sense.

Diagnostics by nature can be quite repetitive, and I’m tempted to say boring; the obvious danger is omission or complacency in your process. This risk becomes greater with experience, the temptation to pre judge or take short cuts is always there. Sometimes the challenge is down to incomplete information, or the dreaded been worked on …
