I had a slight hesitation problem on warm days on my MY2011 SD4 Auto.

That's a good article. I've considered having the gearbox oil changed - I'll get it done as soon as I can. My own gearbox issue is that when it's hot, it doesn't engage into Drive as quick as normal - there is a pause of about 1 second before it engages Drive.

Delete the EGR from the ECU and fit a blanking plate... Goodbye EGR problems forever |

I believe I have cured mine.

I have been told about the software fix and I believe it solves the problem - the main reservation in my situation is that the software fix (or software update if this is the same thing) resets my ECU remap that I had done last year So, if I'm right about the EGR mapping being the cause of my issues, and it doesn't cost too much to get it done, then I'm waiting to get this done first, so I don't overwrite my ECU remap. The other suggestion about blanking it out completely will fix the EGR issue (as well as improving MPG), but there might be MOT/emissions issues. It's a bit awkward to remove the EGR on a FL2 because it's at the back of the engine, and some coolant hoses need to be removed. It will be good to get it cleaned and clear out any pipes just to be sure that the flow of gases into/out of EGR is at maximum. As soon as I can get my EGR remapped, then I can find out if it also solves the problem, then hopefully other people could benefit from this. I'm still trying to find someone who'll do it. Did the software fix affect your MPG? This is the other reason for remapping the EGR - so it doesn't burn extra fuel at motorway speeds, by having lower mapping values. |

I wish you well but I have been on this forum for a few years now and lost count of the number of times people claim to have solved the 2011 hesitation problem. My son has seen it go away with various software resets by dealers but then come back again as the ambient temperature rises in the spring. There again when I took over his car it never happened to me so is it about driving style? My guess is that there are more than one causes and unless you had an FL2 loaded up with data loggers for a few months you be lucky to crack it. LandRover gave up several years ago. Anyway good on you for trying, you might be successful. 3 x FL1 2 manual + 1 auto

Thanks. If everyone who had this problem also had a diagnostic tool, then it would be easier to compare notes i.e. does everyone's EGR% spike at 60% at 1800rpm. My Foxwell will work on all the Land Rovers of a particular date-range as well as Jaguars (it worked on my previous 2004 XJR), so they are a good investment. So you can go from a FL2 to a L322 and you don't have to buy a new diag tool.

Prin reducerea diametrului la 7 mm ati redus si debitul gazelor. ECU comanda EGR pentru o anumita cantitate de gaze si in galeria de admisie ajune alta cantitate. |

Thanks. I will check the O2 sensors again. I am talking about Commanded EGR%. EGR Error gives a fixed value of 72% on my diagnostics, so I assume it is wrong. So I will calculate it - I think the formula for EGR error% = ((EGR actual - EGR commanded) / EGR commanded) * 100%, so I'll try to get these values from my Foxwell. |

I see that this hesitation problem is rearing its head again.
