An update:
After several installers replied that there was no kit available for the T6 CJKA TSi engine, I approached Prins themselves who put me in touch with an installer in Huddersfield. As that is only 20 mins away from Exploria, who I was visiting today, I drove round on the way home for a discussion. Here are some of the salient points:
1. Warranty - my van is only a few months old, so I have plenty of warranty left. I was informed that although the dealer might jump up and down and claim that the warrranty is invalidated becausee of an LPG conversion, they can only really object if they can prove that any failure was directly caused by the LPG system. So they can’t refuse to repair a broken gearbox on the grounds that LPG was fitted. The installer/Prins won’t take on any part of the warranty that may be affected, other than they do warrant their equipment. So if a failure occurs that “may” be caused by LPG, say burnt valves, things may get a bit tricky. I am going to speak to my dealer in Preston to try and get their general agreement.
2. Tank - one of the biggest practical issues with fitting LPG is the size and location of the tank. I had hoped for underbody tanks, thinking that as I don’t have any water tanks etc. underneath there should be room. However, I have been warned that such tanks may not be very big (though several can be connected together) whereas one that replaces the spare wheel is about 90 litres. I definitely don’t want to lose any space inside the van, so I may have to accept the loss or an alternative mounting of the spare. As for the filling nozzle, I’m hoping that it can utilise the vacant Adblue filler space below the petrol cap.
3. Cost - not as cheap as I hoped. I was told it would be about £2300 + VAT, which is about the VAT more than I was expecting. I suspect that if I start requesting multiple fuel tanks then it will get more expensive.
4. Mapping - not that I find the exising 204 bhp lacking in any way, but it is always on the cards that I will get my van mapped at some point. Apparently, this may be problematic with LPG. The Prins kit is tailored to each specific engine model, and if that engine starts behaving outside its normal parameters, then the LPG brain may have a fit. It may be fine, or it may just limit the available increase. Hopefully this would be a challenge that Pendle (just up the road from me) will relish!
5. Time - at the point of ordering, a deposit of £800 or so is paid to order the kit from Holland. This will take about 4-6 weeks to arrive. The installer would then want the van for about 7 to 8 days - though he admitted that he likes to drive the vehicles around for a few days post conversion to make sure that they are running correctly, which is included in that time.
6. Prins - they are apparently based in Holland and one of the biggest LPG conversion firms out there operating throughout Europe.
New: Prins Dual Injection technology
So there you have it. I may have mis-understood any of the above, so don’t take me to task if I’ve got anything wrong, but please feel free to comment/correct me. However, that is my current understanding, and I will be speaking to my dealer and then hopefully getting an order for the Prins LPG conversion in early next year.
