I have a Citroen Dispatch first registered in May 2009, which has done 58,000 miles. It had two anti-roll bars under warranty and now, out of warranty and less than 20,000 miles after the last one, it is knocking again.

Am I unlucky or is this a problem with the type? Should I be seeking further assistance from Citroen or is there a modification which the dealer should be doing? This apart, I am well pleased with the vehicle, which is kitted as a seven-seater.
