The2.5 TDI engine described is a V6 with a 90 degree split angle and a total displacement of 2,469 cc. The compression ratio is relatively high compared to today’s standards, at 19.5. However, the design of the R5 had a compression ratio of as much as 21, although the later version was lowered to 18.5. Luckily the 2.0 TDI engines in the Audi A3 don’t have balance shaft modules, which were problematic in other Audi cars. This leaves us just with potential cylinder head problems.

The 2010 version of the 2.5 TDI CR engine was redesigned, correcting the previous problems of turbo failure. The DPF life is about 100,000 miles. Many DPF problems are down to faulty pressure sensors. biju2000 6 posts · Joined 2017. #10 · Aug 12, 2017. Yes the problem is only at idle hot. CGLC or CJCA has only one pressure sensor on the top of the engine which trigger between 0.3 and 0.6 bar "sensor for reduced oil pressure". There is no pressure sensor near oil filter like CAHA or others. Theirservice life was extended in the A4 B7 hidden under the Seat Exeo body, produced since 2008.

The main TheCR engines are much better than the PD, a lot less problems. If you do get a CR might be worth getting one that is 2011-2012 as the early CR engines 2008-2010 suffer with the oil pump balance shaft, where the hex key (77mm) would wear to an extend that you would lose oil pressure.
