diesel help......
evening people im looking for a few pointers so my tourer is starting to give me grief (first time in 3yrs),now how to describe this problem so starts great every time, pumps work great now when you come to drive it its very sluggish ie you can floor it and it well does nothing for a while then the turbo spools then it feels as though im only getting minimum boost does that sound like virton seals or maybe some thing electrical, now i have been running with full decat plus egr blank 160 map plus ron box set at 7 for 2 1/2yrs now i know alot will not agree with that but.
thanks gordon. |

Are you getting black smoke or any whistling sounds to hint of a possible boost leak?
Easy test is as above unplug the MAF sensor, common point of failure causing delayed and reduced power. If that fixes the issue then it could be the sensor being out of spec, but also worth having a look/clean out of the EGR If that doesn't solve the problem then check the intercooler area , as you've already mentioned the seals can fail. Replacement is cheap & easy so worth considering if not been done already |

If it comes on boost around 2500rpm, it will be a failing MAF sensor.
