Re: Euro 6 engine software update letter?

It does sound like very similar issues and it may well be worth starting a new thread, especially as they may not be related to the software update.

The pedal was one of the possible culprits, but it looks like your dealer swapping that out has made that less likely. It's probably the same pedal gubbins as in all the other current Panda models, and likely in many other cars. That being the case, it would probably be happening elsewhere - which brings us back to the MTJ engine, the fuel input or the ECU.

I notice no difference from the car being cold, or warm, or having sat for a while. Whilst the engine is under load, and having to work to keep a steady speed or accelerate, it seems to be fine. It's only really noticeable when going along flat, or slightly downhill bits, or when coming out of junctions. If the engine isnít under load and the pedal position hasnít moved, or has been up and is then going down again, there are times when engine doesn't seem to be able to quickly decide what to do. The revs then seem to monetarily drop and you can feel the power surge off/on if moving, or it will stutter if coming out of a junction. Once she has made her mind up, then off she goes, albeit maybe not quite as strongly and smoothly as she normally would when sheís working well. All very frustrating.

Re: Euro 6 engine software update letter?

Sounds like old fashioned weak mixture. Make sure the plugs are properly gapped and not wide. I fitted Denso iridium plugs in my 1.2 and the difference was astounding. Certainly in the first instance it may even be an idea to reduce the existing gap by a couple of thou. Used to help cars with a slightly weak mixture.

Re: Euro 6 engine software update letter?

Sorry. My last post refers to petrol engines, I forgot we were discussing diesels.

Thanks for all of your input mate...it's very much appreciated.

I'll start a new thread over the next few days when I get a chance to sit down at a real computer, then I'll shoot you a PM, or drop a link in here if there's a minimum post limit for PM's.
