Hey guys
I'm suddenly struggling to get much over 30mpg around the doors from my a4 136bhp. I'm getting 100-104 miles to £20 of diesel, the car has recently been terracleaned, oil and filter change, timing belt and water pump, new egr valve. Does anyone have any suggestion on what could be wrong? The book states urban mpg should be 52mpg however we all know that's bull. But as low as 30mpg? I was getting more mpg from my 1.6 petrol Nissan qashqai
