Driving home today the "Engine Fail Safe" mode came up on the dash, with an amber light.
Is this serious? The car drove ok but did sound a little "tappety" Its a 1999 S Type.
Any advice?
Cheers Gav

This happened with my S-Type several years ago, intermittently. Took the car to a JMD and the fault code revealed the possibility of a failing lambda sensor. The JMD receommended that I did not have a new sensor fitted at that time and instead check things out again at the next service, which I did. It was then recommended that it was changed so it was. No problems since.

It did happen last week and then today so it could be similar problem...Did your engine sound ok?
Do you remember how much it cost to repair? Im gutted! I got rid of a nice x300 for this car....

Engine sounded fine, performance was not seemingly affected. Not sure of the repair cost because the car had an extrended warranty at that time. Got a feeling the sensor was about £400, then there's labour.

When mine did this sometimes (2.7D) it was caused by a mouse nest under the engine cover...

When mine did this (2.7D), it required 2 new Turbo's!

Luckily covered by an AA waranty I had!

I have to say, I didn't often push the car that hard, just enjoyed driving it!

On the day it went I had hust comlpeted a 200 mile trip to Hull when the light came on. I drove back 200 miles at a steady 70 mph, and the only difference I noticed was that it was slow to pick up, and going up a rather steep hill, it kicked out a lot of black smoke.

Sadly I sold it 12 months ago, not the best decission I have ever made with regards to cars!

From memory it had done about 80K at the time?

I had the car from 28k to 96k. Had a few issues, but that aside, it was a great car!

Mine's on 90K and the turbos do whistle for the first mile, more so in this very cold weather, but otherwise fine. I thought that when a turbo failed you got a big cloud of white smoke...?

I have to trust the main Jag dealer who's diagnostics were inspected by an assessor on behalf of the AA due to the value.

They 1st replaced the left turbo, and then they found the right had gone as well when they did further tests.

No problems before this, car ran like a dream, and no noticible difference afterwards, ie no extra power due to new turbo's rather than turbo's that had done 80k!

Main dealer comunication was 1st class

Hmm!

My dealer diagnosed (1) low fuel pressure (2) high fuel pressure and (3) the need for a new fuel injector. About £500. In their defence they also found the mouse's nest. I removed it and the problem stopped.



I think if someone tried to sell me two new turbos I'd need the old ones to be a bit more broken smile

I guess that's why the AA employed a professional to check the diagnosis of the Jag main dealer on their behalf before they parted with 'their' money?

It was not my place or business to question the diagnosis made by the Jag main dealer when someone else (who knew what to look for / knew what they were talking about) was checking on behalf of the AA before confirming the work could go ahead!

Were the mouse eggs blocking up the injectors?

The covering on some wires had been nibbled - not through to bare metal but evidently enough to upset the system's composure. Either that or the nest (made from fluffed-up sound insulation) may have been causing things to get too warm.

I cleared it all out and left the engine cver off for a week so the stowaway found a new home. The cost for the diagnostics was £36 so not too bad. There is no readout for 'mouse' it seems!


Are whistling turbos a sign of impending doom or do they all do that?
