AG LPG Service (Read this!)

scott02464 · Jan 5, 2011

Iv got an AG multi-point system fitted to me 4.0 V8.

I rang round a few places for a LPG service quote. Prices were between £95-£145!!

Finally I rang a place that would do it for 'Half an hour Labour plus price of a Filter'

Fantastic! So off i went thinking to me sen how much the other places were money grabbing Cooonts!!!

Had a great chat with the service guy and watched what he did.....

Litrally took off two jubillee clips, Took off the In-line filter, Put in new filter and tightened up the jubillee clips, fired it up, squirted some soapy stuff on all conections and pipes to check for leaks!!

Thats it!! Thats fooooking it!!

The software didnt need looking at as it runs great and apparently the AG system doesnt need retuning once set!

So bottom line, next years LPG service will cost me 15 quid for a filter and and a massive grin on me face with how much money ill be saving!

I urge anyone else with this or a similar system to do the same and save your sen a bloody fortune!!! £145 my foooking hairy arse!!!!

So they didn't check your long term trims, check the delivery pressure or sniff all the connections ? You get what you pay for.

Rewmer is right Scott; ya may be happy at the money-saving now.....who wouldn't.....IF that's all the others were going to do.

Playing devils advocate, nah, cut to it.........I'd not have wasted the few quid you did spend (filter less than a tenner ffs) on a partial service!

All pipes and joints must be checked, along with pressures....it's these afterall which are most likely and common causes in LPG probs.

Pay cheap, pay twice mate!

Guys thats all true, all connections were checked and good.

Would it run fine if the pressures were incorrect?

Ridesafe · Jan 5, 2011

Quite possibly run "fine" but you won't know if any leakage, or worse, over-pressure which, although most unlikely if system fitted profesionaly, could cause untold problems!

You would think it is because the clever Engine ECU makes up for low/high pressure gas by adjusting the injector dwell keeping the engine running sweetly. It can only do this up to a certain point though and after that

I asked the guy to do me a LPG service... thats what he did so if thats what you do for a service i think ill replicate what he did in future.

He said the AG system, when installed, is set up with the ecu and doesnt need any further adjustments (Also heard the same from somewhere else when getting quotes)

What im saying is how on earth can one place charge 145 quid when thats all thats done?

I would get him to do the next full service on the rest of the car. Think of how much you will save when they just dip the oil and perhaps put half a litre in to top up.

Oh yeah i didnt think of that! And then il get him to hook it up to the PS3 and and re-programme the hooter!

Maybe the £145 place would do it properly,most of the lpg installers I have repaired cars for have little idea about how to set them up.Most seem quite good at bolting on bits and drilling holes,trouble is they dont understand about fuel trims - short or long.Your car is probably not running right,but you have no way of telling.
A proper service would also include checking the security of the tank/s,pipework plus coolant connections on the vaporiser/s.
To tune an LPG system normally requires running on petrol to note short term trims under various engine speeds/loads which are then adjusted to the same numbers on LPG by trimming the LPG software - Often not a 10 min job.Even the E-gas LPG systems I have seen that just run off the K bus diagnostic wire dont seem to be set for life.
So you pay your money......

In that case i could do most of that myself as a routine (More often than once a year) then go and get the trims checked out and set. That way i wont have to pay the £145!
