Used to have a 55 plate 2.0 TDI 140. After buying it found out about the oil pump problem. In my 9 month ownership had to replace wheel bearing, EGR cooler, had coolant system flushed as oil in coolant and also poor starting when cold. In the end I traded it in and went back to BMW's. I fancy another A4 but unsure whether to get a newer 2.0 tdi or a 1.9 tdi and get it re mapped. What is the most reliable and economicle option??
