Hi, I've got a Carravell edition 25 180 bitdi. I bought it private then realised it was using oil, so after checking the Internet I soon realised there was problems with the egr oil cooler on the CFCA engines, then I came across darkside developments at Barnsley, so had an oil analysing test done and wasn't good, but they did a conpression test and said its not the best, but not the worst by any means, so they blanked of the egr cooler and gutted the DPF and remapped it and went like a train, then the exhaust started to blow and the stock one was a ridiculous amount, so I got a bispoke stainless one for half the price and it's now 210 bhp. My oil consumption is still quite high, but a lot better since I started using millers oil.
