LPG servicing

[Berlingo2CV]

Have a 2007 M59 Berlingo 1.4 with LPG conversion which was carried out when before it was first registered in UK. The work was done by Nicholson MacLaren who are still in business but have not done LPG conversions for over a decade - now into motorsports etc. I think this was effectively ordered from new and Citroen got UK installers to do the work before the cars were registered. It is on the autogas register and DVLA have it down as dual fuel. The system is supposed to be serviced once a year, but I can't find anyone who lists this particular installation for servicing. 

Is there anyone on the forum with a similar installation? There is a nice metal plate with the installation details in the engine bay, but numbers and dates added by hand (see pic)

Hoping someone somewhere can help! Also no paperwork or advice on using LPG, so going from memory of 35 years ago I think its supposed to start on petrol and only switch over when engine is warmed up? 

All advice welcome!

Interesting problem! There are some others on here with LPG conversions so hopefully one will pick up on this.
You've probably already come across the following, but just in case:

I had a 1.6 with LPG until I sold it a few years back.

If it is running on LPG with no faults, there are generally two filters to change. A wet filter which is usually around a solenoid valve which filters the LPG in liquid form and another before the LPG injectors that filter it in gas form.

Most LPG installers should be able to look at it as long as they can obtain the replacement filters for it.

I used to do my own and also clean out the injectors which kept it going well.

Other than that, it just needed new spark plugs more often. Twice a year as LPG needs a good solid spark.

I used the list from http://www.drivelpg.co.uk to look up possible installers and cross referenced with a garage sticker and guessed at Kent / East London and just called a few people. Neil at Medway Dual Fuel was really helpful. I think it has been serviced there in the past as he was able to tell me what manufacturer's system was fitted (Autogas, parts from NL) and would be happy to service it!

Much relief!!

Now to build the camping boot jump - made more difficult by the fact that the car is 120 miles away and I'm wondering if I dare just go from measurements on the forum or wait till I can measure myself!

Thanks for the support and advice!
