1. I have had the car since march 2009 so it's been 1.5 years
2. No idea my came with full dealer service history (Sheffield) it's been for a full service and recall for some work too since I bought the car.
3.I have a mixed driving pattern 50% Urban/50% Motorway
Ok I took the car to a friends garage that cleaned out the ERG Valve this was clocked up pretty bad. Rest the dash errors using my memoscan u581.
I then drove it at high rev down the M11 at last night, for 50 Miles 25 Each Way. Was doing 3k revs constant, the car went into limp mode around 5/6 times during the journey, I pulled up on the hard shoulder, switched the car off restarted, although the dash board is showing limp mode ( Red Triangle + Check VCS+Engine Light + Traction Control Light) The car pulls fine when re-stared. Its actually quite scary at night, when the car it hits limp mode, although the motorway is quite at night lorries coming fast from behind is nerve racking. The top speed I got in limp mode was 40/50mph and sometimes 60mph downhill, my foot was routed the carpet all the way in limp mode.
Although I do a lot of motorway driving ? I have always tend to jump to 6th gear asap this means I hardly ever touched 2k Revs always below, this would explain why I my DPF never cleared up, by itself.
After I came back I reset the error again. I have managed to drive about 60 miles urban without going into limp mode. My memoscan u581 does not tell me how full the particulate filter is ? or if I need to do this exercise again. I plan to do this exercise one more time I will fill up with Shell Diesel ( instead of my usual Tesco, no clubcard points for me anymore)+ I will use an additive see how that goes hopefully won't see this error again, and maybe save a lot of money.
