Hi,thinking of buying a nice astra eco4 2004 1.7, not heard of this model until viewing it! anyway the engine management light is on, the seller advised that the issue is with a turbo sensor?,does this mean egr valve etc? i test drove the car, it drives fine but there is no turbo boost or when you put yr foot to the floor the turbo dont feel like its doing anything, is this because the engine management light is on currently? suggest getting a code reader to check it out, the seller said it will cost approx £150 to correct it, i want to buy the car but bit reluctant due to the above! can anyone advise, the car starts and drives fine, but it has no real if any acceleration quickly! any help advice appreciated asap please.thanks to all..
