What is the 2009-2017 Audi Q5 EA888 Timing Chain Tensioner Failure?
The Q5 2.0T uses the EA888 engine with the well-documented timing chain tensioner weakness. The 8R Q5 (2009-2017) is particularly affected as the heavier SUV puts more load on the engine. The tensioner loses pressure overnight, allowing chain slack on cold starts that progressive… Repairs typically run $1,800-$4,000. Severity: high.
What is the 2009-2017 Audi Q5 S-Tronic Mechatronic Unit and Clutch Pack Failure?
The 8R Q5 uses the DL501 7-speed S-Tronic dual-clutch transmission that suffers from mechatronic unit failures and premature clutch pack wear. The heavier Q5 puts more stress on the clutch packs than sedan variants. The mechatronic unit develops internal valve body wear causing h… Repairs typically run $1,500-$6,000. Severity: high.
What is the 2009-2017 Audi Q5 Timing Chain Tensioner Failure (Class Action Settlement)?
The 2009-2017 Audi Q5 2.0T TFSI experiences timing chain tensioner failures that cause catastrophic engine damage. The upper timing chain tensioner fails prematurely (often 90k-110k miles), allowing the timing chain to skip or break, causing bent valves, piston damage, and comple… Repairs typically run $1,500-$15,000. Severity: high.
