Question about 2003 Jaguar X-Type

Multable light warnings

I have a 2003 X type2.5L that just reached 80,000 miles. For the last two weeks it has been telling me all kinds of things. Began with gearbox fault and engine light. Computer scan showed nothing. Then it began saying cruise control fault and engine light came on again. We discovered the battery was bad and replaced it. Then about a week later the engine light came on again and Cruise control fault re-lite. Scan said Mass air flow sensor, but they couldn't explain the warning lights. Now I had alt. cked and it said that it was putting out too much power, around 15 amp instead of the regular 12. They thought it was the main computer going bad. Any ideas??? The car seems to be running ok.

My 2002 x-type did the exact same thing on many occasions and had many repeated trips to the dealership. My "cruse not available" problem was ultimately cased by cracked hoses in the car's vacuum system (which is used in the cruise control and brakes among other things). Have the dealer check the vacuum lines and the breather hose (mine had completely collapsed). Chances are they are leaking and causing your car to "buck" and the cruise to not work. Don't ignore this as it will affect the functionality of your brakes too over the longer term.

I also had the "gearbox fault" with mine at around 75,000 miles. Unfortunately I don't have great news on this one. I took it to the dealer and they had to replace the transmission in the x-type. Luckily for me, I had purchased the extended warranty on the car (due to it's many previous visits to the dealership under the factory warranty) and it was covered.

2009 scion tc 80,000 miles struggles to start

When the warning light is on, you need to take it somewhere to get the computer scanned for trouble codes. Most auto parts stores can do it for free in hopes of selling you some parts. With the codes someone can begin the process of diagnosis.

Do i need to change the timing chain on my A4 2.4 V6 2003 95.000 miles

I'm not an Audi expert, but in most cases timing chains will last 150,000 miles or more. Its timing belts that have to be replaced before 80,000 miles.

When do I need to change the tinming belt on my Suzuki Grand Vitara 2.0 l itre petrol. My car has done 54000 miles. What signs will tell me the timing belt is going

their are no signs taht you can see ,i normally say 80/90 th kms in a dry hot climate and 20,000kms more in a cooler damper climate .The belts tend to dry out quicker in a dry climate ,if you remove the covers and see cracking at the base of the teeth of the belt then is the time to start to think about changing it ,cracking on the outside is not a major problem as this can appear on a belt after a small amount of use as i have seen this after a couple of weeks of changing a belt myself

Emission control light just turned on last night...i read the manual and dont think its a water problem. i have 43k miles on it...could you share what could be the problem...and if its a major cost for a...

whenever the computer sees a problem it stores a code, this code will tell you where the problem is, this cant be major its only got 43k on it, check your gas cap and make sure its tight, a loose or missing gas cap will turn the light on, if its loose tighten it and drive for a week and it will reset if it tight then go to an autopart store many of them scan the compuetr for free and give you the cide or codes , also one more thing, this is a federal law that dealers must warranty certian emmission control parts for 8 years or 80,000 miles, so if the code is something like an o2 sensor thats warranty part, hope this helps.

Water in fuel light just started to come on intermittently. Changed the fuel filters 3 weeks ago or 7500 miles back. Had never changed the filters on fuel or transmission since the first 80,000 miles....

The change in temperature from Las Vegas to Alaska could have resulted in condensation building up in your fuel tank. Also you could have gotten some diesel fuel contaminated with water. The transmission oil should be changed as per manufactures suggestion or at least every 50,00 miles especially if you are towing.
