I don't appear to have one on my 2007 s type -- but it doesn't have a sunroof either [for which I am glad]. But when I saw "Amber light" I thought it might be the "Engine malfunction" light, which cam on in my car yesterday. There are four solutions, after you have diagnosed the problem, which in my case was the EGR valves, as it has happened before. The Four possible solutions are:- 1. Follow the instruction in the manual and take the car immediately to a Jaguar Main Dealer, and they will charge you £69 for a diagnostic check and then recommend that the EGR Valves need replacing. Each Valve - two on the s type - costs about £185 and then there is the labour charge. 2. Take your car to an independent Jag Specialist and he will probably clean the valves with a significantly lower cost. 3. Remove the valves and clean them yourself - dirty job, and I don't get my hands dirty any more, but all you will pay for is probably new gaskets, about a fiver each. 4. Take the car out on the nearest bit of fast dual carriageway, press the S button and give a bit of a blast up to 70mph, come back home, have a cup of coffee, go out and start the car again, and the light will not show. If it does, go back to the beginning. But I would say that it has worked for me three times, and my mechanic has told me that a sticky EGR valve is usually cured by a good blast, Peter.
