Audi S3 (2013–)
The chain cam EA888 engine in the Audi S3 from 2009 to 2012 was widely criticised as badly engineered ('Autocar' 23-10-2019 Page 77.) They suffer worn piston rings, burned valves and failing timing chains. This was corrected in 2012 in the Audi S3 and concurrent Octavias, Leons and Golfs which are exhaust manifold in head with direct as well as indirect injection to make sure the inlet valves are washed with petrol to prevent carbon forming on them.
What to watch out for
15-9-2017: Report of clutch of 2016 Audi S3 failing at 14,000 miles. Dealer reported: "clutch slip on friction plate, excessive heat on pressure plate and flywheel face. No mechanical defects. Requires new clutch kit" and has quoted £2,355.74 (inc. VAT).
4-4-2018: Complaint of transmission lag from 2018 Audi S3 2.0TFSI 310 quatto s-tronic saloon. Will either be the DQ381 or DQ500 7-speed wet clutch DSG/s-tronic.
4-11-2015: EA288 1.8TFSI and 2.0TFSI engines recalled in USA because the rear camshaft lobe is prone to unexpectedly shear off from the shaft. The failure causes reduced engine power and loss of vacuum pump power, cutting vacuum supply to the brake booster and eventually resulting in increased braking effort."A reduction in engine power and/or increased need for braking effort after vacuum reserve has been depleted while driving can increase the risk of a crash," a statement cautions. The campaign affects approximately 92,000 vehicles including the 2015-2016 Beetle, Beetle Convertible, Golf, Golf GTI, Golf SportWagen, Jetta and Passat. In notifying the National Highway Traffic Safety Administration, VAG stated that the root cause of the camshaft failures has not been fully understood. The company is still continuing an in-depth failure analysis and development of a repair solution, however a fix may not be ready until the end of the first quarter of 2016.
