From my personal experience of running both over a period of 14 months the pedal box gives better consistancy, reliability and the better bang for your buck, trying to set the best combination between the CRDT box (Not TREVOR) and the pedal box is definately not a set equation, after months of pushing the boundries and experiencing problems I have settled for 3+1 (Box) and full sport setting (Pedal). I have run this for about 6 weeks and no issues. Pushing my luck results in limp mode and dangerous lack of power when most needed...

Are these still Available? Will they fit the estate/combi? Thanks

I have been running both Crdt and pedal boxes on mine for a year now with mixed results. Has anyone else noticed an electronic alternator whine through speakers when they have fitted the pedal box? This happens whether the radio is on or not...This is common to bad earthing on car audio systems, but can't see why this should effect this application.

The fact that Andrew's car will not run on anything over 4+1 is well documented, so he we won't be able to give you this information...

Any update on this? Mine has failed on me about 6 times on me under hard acceleration on 4+1 now and I am also now starting to think about reducing the setting....

I'm intrigued by this as you seem to be now having the opposite effect to me!!!! Perhaps seasonal temperature and atmospherics aren't to blame?... It would be great to get back to 4+2 at least! Keep up the good work...Out of interest, what made you try the leap to 4+2?

Another thing though, I had a couple times when the stupid stop/start system couldnt make its mind up and decide it would kick in... This is one option I would quite gladly of left on the shelf...

This has actually happened to me also after returning to 4+1, but as you mention perhaps it is due to having to adjust to a different setting, out of interest, this actually hapened to me as I was about to accelerate again after slowing down nearly to a halt, not from a stand still start off... I have had the pedal box fitted for 6 months now and as per above, I have stalled the car, so it is possible... Having said that the pedal box is a neat bit of kit and does compliment the car, I was lucky enough to be able to run my car on 4+3 and pedal box set at Full Sport mode, now that did make a HUGE difference.

I think I'm going to take a closer inspection of mine, sure in the wetter months the restriction stops excessive moisture getting into the box, but in the dryer months (If we have such a thing), the blanks can come out...

Well i'm still banking on the laws of physics, but perhaps you are right... I'm maybe barking up the wrong tree... This is the first turbo diesel I have owned, can someone please enlighten me... Surely I can't be that dumb... :-)

I ran mine for 4 months with no hassle and with consistant driving, I'm more than certain, infact definate that I red lined mine (occaisonally) in fact bounced the needle on miss shifts (I'm not advocating irresponsible driving before anyone chips in) on 4+3 in the colder months and it never brought on the coil lamp. So I guess that with others having the same results, we can again blame the weather... Has anyone looked at derestricting the air flow into the air fiter box by removing all standard intake restrictive plastic blanking parts? I'm not getting into the whole air filter debate!!!! Just whether anybody had taken any notice of the inlet pipe arrangement?...

The risk is your coil light will show and you will lose power and go into limp mode, whilst this will not (As far as I can tell) harm your Car, it may leave you in a situation when you are depending on the power and don't have it, for example in spirited overtaking maneuvers...

I never witnessed any vibration on any setting, started on 4+3, then 4+2 and now the car seems to have settled on 4+1 with no coil light showing... and that is with Pedal Box fitted. I would love to run the 4+3 again, but as explained in an earlier post, perhaps the (slightly) warmer temperatures we are having now effect it, I first fitted the box in November on my car on 4+3 with no problems and it was extremely quick with the pedal box

Makes sense... Less air mass/density... I forget basics sometimes... It will effect the overall fueling ratio/performance. But you tend think modern engines will compensate, probably on the contrary. But you never miss what you never had, and I had it and now miss it. HA I suppose I'll have to wind it back up come winter...

None at all whatsoever, it's just as if the car is getting less tolerant with the box...
