I am not responsible for any injuries or complications that may occur due to your actions while using this guide. Low oil levels/pressure causing tensioner to wear prematurely, this may be due to oil consumption commonly due to broken PCV, valve cover issues, or oil leak due to warped oil filter housing assembly. Poor cam follower maintenance causing metal pieces, flakes and shavings to enter cam cover causing tensioner to wear prematurely. Most commonly, the plastic guides for the timing chain on the tensioner break. Power loss, poor fuel economy or limp mode with check engine light. P000A check engine light sometimes precedes serious symptoms and may be intermittent.

Metal clinging or slapping sound from back of valve cover at idle which may or may not go away under load.

Please feel free to use the videos as a supplementary reference to this DIY. These videos were the only thing I could find to guide me through the daunting task of replacing my timing chain and tensioner. Special thanks to Timmy at Astral Auto Repairs on Youtube for his videos… 'can ya dig it?' I hope to make this process simple and less overwhelming so that anyone who can keep track of where their bolts and harnesses go can do this job with confidence. The most difficult part of this job is ensuring that the exhaust cam sprocket/adjuster bolt is not stripped when you are removing it and that the timing is set right before you close everything up. I know that a lot of people visit the main forum and few go to the B7 A4 Tech section, so I thought I would post here first so that people can see the walkthrough before I have it moved to the tech section.Īlthough there are only a few parts to take off, the bolts can be in unforgiving locations. Then I'll give you a breakdown of the tools and parts necessary to do this job, recommend additional optional parts to replace, and give you a walk-through of the job step by step with a few tips along the way. I'm going to start by talking about some symptoms and causes of a faulty/broken tensioner.

The timing belt and manual tensioner unit at a minimum must be replaced during scheduled maintenance intervals to maintain reliable and safe operation.The timing chain and tensioner on the 2005.5-2008 Audi A4 2.0T engine commonly causes issues and it has been difficult to find a concise DIY walk-through, so I thought I'd write one since recently doing the job myself.

Timing belts may also increase/decrease in size minimally during seasonal temperature changes, always check tension and adjust as necessary during heavy temperature fluctuations.Īlthough the IE manual timing belt kit is an upgrade over the OE setup, be sure to follow the factory timing belt replacement intervals. Timing belts tend to 'stretch-in' after installation, IE recommends you check your belt tension often (every oil change) and adjust if necessary. The IE manual timing belt tensioner is a much more reliable timing upgrade over the stock hydraulic setup, however, this is a performance timing setup designed for performance engines and requires maintenance to ensure proper long-term operation of your timing system. This setup is proven on many street and race applications and is used by VW/Audi 2.0T FSI successors after the 1.8T engine was discontinued. This tensioner is set to proper timing belt tension and tightened securely into place. The auto-adjusting tensioner is then replaced with a traditional style manual tensioner. This two-part timing solution includes a new in-house CNC machined aluminum idler bracket that replaces the hydraulic piston assembly. The IE Manual Timing Tensioner Kit is designed to give you timing confidence by completely replacing the 1.8T timing belt tension system with performance-minded parts. Many of the available non-OE tensioners worsen this issue further with cheaper components, lack of quality control, bad tolerances, and awful surface imperfections that further lead to rapid degradation of the hydraulic o ring. The piston arm on the tensioner is sealed with an under-spec o ring that commonly wears out, cracks, rots, or leaks leading to the instant discharge of the hydraulic fluid resulting in complete engine failure. Unfortunately, this design has been a constant source of complete timing failure and one of the weakest links on the 1.8T platform. This hydraulic tensioner has a gas-charged piston that provides tension on the tensioner roller, designed to increase/decrease tension automatically. All 058 1.8T 20V engines are factory equipped with a hydraulic style timing belt tensioner.
