Mr A Lawrence Posted November 28, 2017 Share Posted November 28, 2017 First FTP in the jag in 3 years!! Restricted performance message lit up accompanied by limiter not available. No fault codes logged. Anyone got any ideas what it could be? Link to comment Share on other sites More sharing options...

AMC Rebel Posted November 28, 2017 Share Posted November 28, 2017 What Jag? If it was mine I'd check the earth points and battery connections everywhere - then maybe the battery itself. When the earth points disintegrated on my previous X350 there was a series of totally spurious but increasingly alarming messages, none of which was "true" because the systems didn't know how to respond to earths being bad.

AMC Rebel Posted November 28, 2017 Share Posted November 28, 2017 Is it an actual ftp or just these messages? Link to comment Share on other sites More sharing options...
oldcars Posted November 28, 2017 Share Posted November 28, 2017 Still a nice place to sit while FTP is occurring. uk_senator 1 Link to comment Share on other sites More sharing options...
Mr A Lawrence Posted November 28, 2017 Author Share Posted November 28, 2017 It's an 06 2.7d Stype. When the warning comes on the power cuts and it won't go over 2k rpm. Would a blocked/old fuel filter cause this? Link to comment Share on other sites More sharing options...

Mr A Lawrence Posted November 28, 2017 Author Share Posted November 28, 2017 Turbots are fine. They were replaced just before I bought it. Link to comment Share on other sites More sharing options...

Would a blocked/old fuel filter cause this?Ah - my X350 (same engine) did this. I spent a lot of money at garages trying to fix it and it was never really fully cured. Mine would go back to normal as soon as I found a place to pull over and restart. It was made better by replacing the EGR valves and some other bits - but there was a stored code that indicated an imbalance between banks of cylinders. There are a lot of people out in the internet with the same issue and seemingly not many permanent fixes. Mine did it more in damp weather. I don't have any good news - and this was another reason I ditched that car. Link to comment Share on other sites More sharing options...
0ldCh0d Posted November 28, 2017 Share Posted November 28, 2017 Turbo related? Check all the pipework. What Bren Say's,Check the pipe work, The S Type that I bought & then sold to my Dad, did this very thing about 2 weeks ago, It turned out that it was a split pipe, after the MAF Sensor. However, this is a 3.0 V6 Petrol, so might not be the same on the 2.7 diesel. Cost was £35 fixed. Link to comment Share on other sites More sharing options...
privatewire Posted November 28, 2017 Share Posted November 28, 2017 Do these have a DPF? My old diesel X type would go into DPF cleaning mode after a while if it had only been used for short journeys. Usually cleared itself after a few miles and a restart . Completely different engine mind, so probably no help at all. Sorry. Link to comment Share on other sites More sharing options...
AMC Rebel Posted November 28, 2017 Share Posted November 28, 2017 Do these have a DPF?06 will have Dpf unless a very late reg. Early 2.7 S-Types didn't have a dpf - but not many of those around. privatewire 1 Link to comment Share on other sites More sharing options...
cort16 Posted November 29, 2017 Share Posted November 29, 2017 Does it go into limp mode when you accelerate or just when you're driving normally? I remember a Citroen C5 I went on a charidy rally with would throw overboost errors and go into limp mode if you applied too much throttle.Turning it of and turning it back on fixed it. Does this have some kind of turbo boost solenoid that could be causing the errors? It should be easier to diagnose if you can demonstrate it to someone with the right machine.
