I HAVE A 2.0 HDI XANTIA 2001 MODEL & KEEP GETTING A POWER LOSS (E.G WHEN TRYING TO OVERTAKE) the fuel filter has been changed etc. one minute it will go then it won't. it is as if the turbo is not boosting, there is no codes loged in the ecu reading, it is getting worse ... any help would be greatly appreciated. thanks andy.

hi my c5 2.0hdi 2002 occasionally whilst driving along i get an audible bleep and all four suspension height lights flash alltogether and stay on for around 10 seconds. then it might not do it again for another 30 miles. anybody got any suggestions please? cheers andy
