#1 of 44 Major engine problem by tedman Mar 16, 2007 (10:17 am)
I purchased a 99 XJ8L with a remanufactured engine at 54k miles in 2003. My CHECK ENGINE LIGHT came on 72k in 2007 so I went to my mechanic who worked for Mercedes-Benz. He has a side business. He said I needed 4 sensors 1600 and an Air Flow Meter 260.00. The job was done but the C.E.L. stayed on. I took it to the dealership. The service man said that my air filter housing was cracked along with a hose and minor wirirng of 307 dollars. He called me and said everything is ok and to pick it up after he test drives it 5 or 10 miles. It was driven 18 miles. The service man called me and said I would need another engine. I still owe on vehicle. Is it worth the money to fix or should I suck it up and take lost? Is there reliable data on these engines?Are there legal avenues to pursue? The car was doing fine before I took it in. Replies to this message: djagman (Jul 25, 2008 10:33 pm)
#2 of 44 Three Engines Two Too Many by freeoppressed Mar 23, 2007 (1:43 pm)
Sure doesn't pass the smell test. The was a period of time when XJ8's had a problem with NiCad linings on their cylinder walls. I don't know if the problem stretched into 99 or not. There is plenty of info about the issue ont the web. Certainly, you don't run less than 20,000 miles and need to replace the engine each time. I have a 1998 Jag XJ8 that I purchased with 72,000 miles. It now has 203,000 miles; doesn't use a drop of oil; and runs like a top. If somebody didn't satisfy my inquiries, I think I would look into legal avenues to approach. Replies to this message: tibimakai (Apr 08, 2007 6:13 pm)

Replying to: freeoppressed (Mar 23, 2007 1:43 pm) I wouldn't buy a pre 2000 XJ Jaguar. They could have a Nicasil problems in the engine. If it has this problem you need to replace the engine(!!). Check the VIN # to have the last five characters beginning with A_ _ _ _(the A is important). Those cars with A in the VIN # have steel cylinder walls not like the pre 2000 once(cylinders bored out from the aluminum block and coated with Nicasil). To make sure that you don't have this problem you should take the car to a shop where they can make a cylinder leak down test.
#4 of 44 XJ12 oil leak by kwrp Apr 26, 2007 (8:40 am)
I discovered an oil and white pasty leak under the front part of the engine. Any idea what causes this and how to fix it? Replies to this message: euphonium (Apr 26, 2007 9:19 am) kwrp (Apr 27, 2007 7:57 pm)

Replying to: kwrp (Apr 26, 2007 8:40 am) Check for leaks in the transmission cooler line. Often tranny coolers have a small radiator mounted in front of the engine radiator and tranny fluid is cooled by it.   Another possibility is the need to replace one or both of the main radiator hoses due to corruption over time.

Replying to: euphonium (Apr 26, 2007 9:19 am) Thanks for the response, I took it to my mechanic and they couldn't find an oil leak. But had to top of the trans fluid. I'll definitely keep your comments in mind as I start out this driving season.
#7 of 44 1996 XJR Not started in 6months and now wont start!! by eshaze May 21, 2007 (8:00 am)
Hi there i've got a 96 XJR, I started it 6months ago with no problems it used to be a daily driver however since moving abroad I haven't started it for 6 months. After coming back into the UK I knew that the battery would need replacing so I bought a new one, I've turned it over and tried to start it and it doesn't fire what so ever, what could have happened in the time that it was standing?? any help greatly accepted thankyou Sam Replies to this message: euphonium (May 21, 2007 8:07 am) kwrp (May 21, 2007 8:48 am)

Replying to: eshaze (May 21, 2007 8:00 am) Perhaps there wasn't enough fuel stabilizer in the petrol tank while in storage. For ignition you need fire and fuel. Your battery supplies the fire so I question the quality of the fuel.

Replying to: eshaze (May 21, 2007 8:00 am) I can tell you what happened to my '94 XJ12. I bought a new battery and discovered that the starter wires had corroded sp? and had new ones replaced. It starts every time.
#10 of 44 2000 XJ8 ASC/TRAC/Failsafe Engine Mode Lights! by lzolidis May 24, 2007 (11:35 am)
The ASC not available and TRAC not available lights came on when I was driving last week, triggering "Failsafe Engine Mode" as an immediate response. The dealership service center tells me the car needs a new throttle body assembly at a cost of $1550. They looked at the exact same problem 8 months ago and replaced a module (for $1700). Should the throttle body issue have been caught on the first visit? Since the dealer says the current problem is "new," it falls outside the 12-month guarantee of their work and I'll be out both for the repair and the rental car.
