Excellent news on the new abode Dilli.
Couldn't put this in the 'what have you fixed lately' thread as I didn't do the work but it did make me happy. I recently found a leak of coolant emanating from somewhere in the rear wheel arch of my car. I knew there was pipework under there serving the rear air-con/heater unit so guessed that was likely to be the problem. A little searching yielded the answer I didn't want - a design fault which meant that a small vulnerable area of the pipework was prone to corrosion from road salt etc. and required the entire rear section of pipework to be removed and replaced. Fearing a bill of c. £750, I had a look at the rest of the pipework under the car and noticed that the front and rear sections of the pipes were connected with flexible hoses so I thought an acceptable work around would be to simply join the flow and return sections at that point thereby isolating the damaged rear section in situ. A local garage did the job for £60 a couple of days ago and so far so good. We've never used the rear heater in the car anyway and only rarely use the rear air-con which still functions properly so I'm a happy bunny right now.
