Not been on the forum in a while mainly because the car has been running great. Now has 220K on it and has been very good to me so far. However i had an issue today where car was running fine then out of the blue it was very sluggish going up hill even on the flat it was very very slow. This proceeded to be the case for about 15 miles of driving over country roads with short steep climbs and descents. There was no engine fault warning on the dash or any kind of lights on the dash at all either.
So after a while of this i noticed i have turbo assistance back but that the turbo was kicking in around the the 2000 RPM point where it normally comes in around 1600 to 1700 RPM. Then i went on a long down hill run for about 3 miles and then everything back to normal again. On the way home i got in alongside a new 19 plate peugeot with the adblue engine in it and he was shifting on but i managed to keep up with him all the way till i turned off that section of road.
Upon arriving home i done a quick code read where i found a manufacturers code P11AB which WAS NOT in the stored codes section of the reader. Upon googling this it appears to be connected to a multiple number of issues but seems to centre upon boost pressure sensor or boost pressure solenoid. One suggestion was that a blockage in the fuel filter can reduce fuel flow which in turn could restrict boost pressure. The car has been running fine for a while again and no re-occurrence of the issue so far so not sure if it is serious problem, start of a problem or just one of these odd things that crops up.
I suppose the best i can hope for here is that it is just a blocked filter which is due changed soon anyway or just one of these things that happens.
If anyone has seen this code crop up and know what it is likely to be a heads up for it would be great.
Thanks
