Audi S4 4.2L V8 Timing Chain Replacement – Audi Repair Denver
This Audi S4 came in with camshaft timing errors in the ECU at around 100,000 miles. Tests revealed we had a problem with the camshaft timing and suspected boken timing chain guides. To repair the timing guides the engine must be removed. We ended up replacing most of the timing chain guides and the chains. This was an extensive repair.
