The current trend from Euro car makers to create big power out of 2.0 litre turbocharged four cylinder engines could be showing the first real signs of stress. Last week we brought you news of a Mercedes-Benz A45 AMG on fire in Sydney and now there’s reports of turbo dramas affecting the latest range of Volkswagen Group hot hatches.
While the cause of the fire in that A45 AMG is yet to be established, getting 265kW from a 2.0 litre with such high boost has raised many eyebrows for those considering long-term reliability. That’s not to say it can’t be done, but a quick look at relevant forums will show there’s plenty of A45 owners with issues of varying types.
Similarly, the latest EA888 engine from the Volkswagen Group which is tuned to produce up to 221kW and used in the Audi S3, Seat Lean Cupra 280 and Volkswagen Golf R is attracting a number of complaints, mostly to do with turbo failure.
According to an article published by Motor Authority the part number of the faulty turbo is 06K 145 702 N which they report is made by IHI Turbo. The relevant engine codes are CJXB and CJXC.
Motor Authority’s investigations point to a production fault for turbos made between April and May 2014, where there is a fault with the manifold sealing surface. Outside of this date range some owners of 2013 S3s are also reporting similar problems.
It’s been suggested Audi will be fitting a new turbo design for future S3s and has in turn delayed the launch of the TTS until the problem has been satisfactorily resolved.
Which begs the question, is the Mercedes v Volkswagen four-cylinder war one that is really worth winning?
