Hi all... I recently bought a one-owner X150 XKR with low miles (40k) NOT from a dealer but a broker who had presented the car with a Health-check by the local Jaguar dealer.

So I didn't buy it blind from one of those 'prestige' dealers that scoop up the over 5 year old trade in's from the main dealers. Valet them, stick a big (lots of room to negotiate) price on them backed up by a Guarantee that has all kinds of caveats attached (electrics, hoses / pipes, sat-nav etc not covered)...

I knew what I was buying and budgeted for new discs, pads, full service (with Jag supplied plugs, fluids, filters). Had the car waxoyled (hope they didn't block the A/C evaporation pipe 'cos if they did there's going to be a soaking wet passenger footwell and a disgruntled mechanic taking out the dash to replace a little piece of pipe)...

And looked forward to learning to ease my way into supercharged driving - entirely different to an 80's Porsche 930 Turbo I owned back then - as well as learning to reverse through my standard size up and over garage door with 1.5" to spare either side with the mirrors out.

All good - but suddenly tempered by the fact that every time I had to make SMALL blip and brake on the throttle as I tentatively edged my way into the garage the ENGINE WARNING light comes on....

Once on the road the car didn't hesitate, drove / surged smooth and took off like a sling-shot with no apparent problems BUT the engine warning light glaring at me diminished the pleasure and excitement somewhat.

When my able mechanic plugged in his Snap-On ECU reader, it gave the following readout:

PO171 - System Too Lean (Bank 1)

PO174 - System Too Lean (Bank 2)

Once re-set it wouldn't reappear until once again I had to make tiny adjustments to the steering, brakes and throttle - moving at six inch intervals - and blip: the engine light's back on the dial.

I can't keep getting it re-set by the garage - and I can't ignore it in case it masks a newer, bigger problem somewhere later down the line...

So HELP! How do I get my ECU to disregard the signals / change its response to the very small blipped in-puts of throttle / brake and steering?

I'm hoping someone out there will know the answer.

Thanks JD

 

Hello, JD,
I'm familiar with all the caveats connected to warrentees and guarantees, I recently spent a very tense week trying to buy a replacement DD as someone wrecked my previous one.

Basically, only items that are touched by oil are covered in California. That means engine and transmission. There was no mention of power steering, but as it's bathed in oil that should be covered too.

Welcome.

A repost in the X150 section will get the answers, but retyping all that is a chore.

When the planets align better, one of the Moderators will "copy/paste" it for you.

It will cost you drinks shoudl you ever meet in person, but what the heck, any excuse for "drinkies" is good in my book.

I have no answers, but I would have thought the "brains" were smarter than that??.
