I've notice a subtle amount of surge in both my Puma's most noticeably in 1st & 2nd in both high and low range but it's only when moving on very low throttle or tickover. I've made a point of ensuring the pedal is motionless so I'm of the school of opinion that it's down to the anti stall. Steve.

Brake lights all work fine. It was doing it pretty badly today at one point, but only for a few seconds. 2011 110 USW

TBH if you are not happy or concerned about it I'd run it back to the dealers. That option is probably less worrying than a bunch of people suggesting the 101 things it might just possibly, perhaps, may conceivably be, have you tried x, y or z plus the price of potatoes when in fact it might not be anything other than characteristic of the vehicle

Miserableolgit. I can see where the name comes from now
Take it to the stealers - where's the fun in that when we can all second guess at what it might be ? ! Even if you're right  |

Or take yourself to the dealers, try a couple out and take yourself out of the equation
 I have driven 3 other Puma's now without clunky gearboxes and I couldn't get mine to surge just now. Tick over is only something like 900 rpm so I think if you get the revs up it will be fine, especially when towing. Getting the revs up to 2000 rpm + for changing gears and it also gives you time to change gear more precisely and slowly  Apologies re sucking eggs etc... |

I really think the driver can be the problem.......I'm beginning to think I'm the problem. my seems to run sweet sometimes and I feel like I can take it to over 3k without the enine blowing up othertimes I don't dare take it above 2k ? I've taken it to several places and yet everyone gives it the thumbs up. so although I'm sure they're all wrong the common problem seems to be me. any how I'm still not convinced but I don't know how to quantify it either. been trying different mixes of bio (including none) and it all still seems inconsistent? I've just bought some castrol actevo 2T and hope this sorts things out (I also hope thats the right 2SO?) but at the moment although I'm sure its not me the evidence seems to suggest the problem is all in my head   |

I reckon Zag has a point in that there's no substitute for trying other Defenders and comparing like for like. Steve.

They are funny things, just last night I was doing about 55mph in 6th and wanted to find a 7th gear...weird, other times it feels such a relaxed cruiser... 2011 110 USW

I change into 6th from 50+ mph
I think there is a section in the manual about what speed/revs to change into each gear. Will have a look after work...mutter and 29 Degrees today down here  |

I've had the same surging effect and I put a post on here quite a while ago. I thought about the foot on the pedal moving etc but ruled this one out. Symptoms same as yours - generally light pedal up slight incline, medium revvs - mentioned it to the dealers but no fault found. However, the recent ECU mapping update seems to have reduced the effects quite a bit.
Other suggestions at the time were the MAP/MAF sensor failure (no failure codes found on mine). I think that there may be more than one contributory source - ie driveline backlash, light use of throttle, turbo spinning up etc but the ECU update made the big difference to mine |

Report this to the dealer, get them to up-load the latest software and ask them to check that the software has actually up-loaded (sometimes it says its loaded but does not actually up-load). this should stop the surging problems. 130's have feeling's as well you know  |

I'd have thought a May build truck would have all the latest stuff already? I have to ask them about something else so will mention this, but its not a major concern, I was really wondering if it was normal or a problem. 2011 110 USW 1973 Series III 1-Ton 1972 Series III 1-Ton Cherrypicker 1969 IIA 1-Ton 1966 IIA 88" |

Not a 110, but my 90. I'm in 6th as soon as the engine can pull it. This is about 32 mph (as shown on the speedo') on the flat and it will pull from there without changing gear without straining things. It doesn't rocket forward from 32 mph, but will pull top o.k from here. On a good day he'll trundle along at 30 mph on the flat in top. Obviously I'm not towing anything. There's no surging either. The bonus is that you don't need to be changing gears all the time and from 35 mph with suitable road/traffic conditions you can leave him in top all day.
