ah yup diesel sport, thanks for that i checked the website of the company and cannot find bmw x5 in the drop down list of the vehicles that the product supports...and are there are any gurus out there who know if this type of sealant/air con top up can do damage?read in the reviews and online that there is a 50 50 chance of repair success depending on which part of the aircon system the leak is....x5 diesel is suited to this place, great up mountains much better than doing short runs on the m25 in london....although it is very dusty here due to sand from the sahara blowing across! and the air filter change on the diesel is near impossible i have read and seen...oh well
