a mate is looking at buying this anyone had any issues with LPG ?

thanks all

[reserves]

That's the first one I've ever seen that's had it done!

Hi there that S4 was advertised about a month or so ago twice. at the time some members said that it looked like it was "sat strangely and that something else was dodgy about it just to let you know

[musty1]

as for the lpg there should not be a problem with it, far as I know there is a lpg kit on a mitsubishi evo with 700bhp with no prob'e. My old man has ls400 4.0 v8 on lpg and still drives like a bueaty.

I bought a boat from a guy a couple of years back who worked for a company that installed LPG kits (near Salisbury). He used to race a tuned S4 on LPG in some challenge cup.

We took the car for a spin after I reset these engine codes on VAGCOM the following codes came back I reckon as a result of running on gas for the lean readings but are the Lambda sensors gone ?
if so any ideas on replacement cost ?

the car was clean as a whistle and has a full stealer service history, it has been LPG for 50k of its 100k just think maybe the lambdas may have had enough but done really know

i know lpg has lower emissions that are not picked up by lambda's sometimes, did you get the problem on petrol? if not then its the lpg, for example my mate had a engine management light come on his impreza with lpg it was running so clean

Similar codes when MAF is shot

[tartan_rob]

MAF figures are an immediate tell tale if the MAF is shot.

[kies4]

I didn't see the maf readings go over 200 but rev range was changing quite a bit, very nice owner encouraged my pal to use his right foot alot.

My pal is dead keen, will have to speak to doug about mapping

Did your mate buy the car?

[kies4]

yeah he did, he's very happy with it, one of the springs was broken but that was all
