I was interested in your response to a reader suffering a Turbo trouble with a Nissan X-Trail. The turbo and intercooler on my 2005 X-Trail were replaced by our local main dealer in December 2007 at 42,000 miles. I had missed a recommended service interval and was forced to pay for the replacement parts and labour. At MOT in August 2008 a leak in the intercooler was identified and the car was returned to the dealer in early September last year at 55,000 miles for a check-up and service. Apart from cleaning off the oil, no repairs or diagnosis were made. The oil has continued to leak and, on inspection at the same dealer a week ago at 62,000 miles, we are now informed that the turbo and intercooler both need replacement. Nissan Customer Services has offered to replace the turbo (as a warranty item) but claims that the intercooler is a consequential fault and I can expect a bill for £365 pounds to replace it. My view is that the car was returned with an independently identified fault in the intercooler within a year of the intercooler's replacement. It should have been identified and replaced then at no cost to me. Am I being unreasonable?
