I popped in to see you guys a few weeks ago regarding power fluctuations and you gave the car a VCDS code read. The results were as follows, but tonight we seem to have an updated problem beyond the issues when I came to see you;
On my way back from Skelmersdale tonight, from literally moments after setting off the car would 'jump and jerk' under acceration to the point it feels like you are slamming the brakes on. Also it would also use a lot more fuel then normal to the point you can see the miles-till-empty dropping quickly. Once the on motorway the car would generally feel OK put only to the point that it was a steady speed of 65-70mph.2 Faults Found:
16490 - Manifold / Barometric Pressure (G71) / (F96)
P0106 - 35-00 - Implausible Signal
16622 - Manifold Pressure / Boost Sensor (G31)
P0238 - 35-00 - Signal too High
Readiness: 0000 0000
Coming off the motorway the car would react in the exact same way it did when the engine was cold, and it literally felt like I gave the car an emergency stop as I set off from the roundabout. Again the car was using more fuel and in 1st, 2nd and 3rd gears there was absolutely no power at majority of times. My original thoughts (and passengers) was that it could have been a case of having to pull over and call breakdown not knowing exactly what damage this could cause to the engine.
As I puilled up at home, reversing onto driveway the car seemed to near enough lose all power and I don't just mean engine management wise. Anyway fuel temps were perfectly normal all the way home and there are no signs of funny engine noises or smells. Could this just be my MAP sensor completely on it's way out or is it causing fuel pump/pressure issues? I know most of you will tell me that I should have just got the problem fixed from the start but unfortunately I can't afford it and that's the way things go.
ANY IDEAS? Cheers in advance
