200K ABY Avant

[psiconauta911]

Intermidiate milestone!

[psiconauta911]

A litle update:

The Avant has gone to the doctor, a young mechanic who owns an AAN S4 and is a former international rally team mechanic who as a natural gift, I´ve seen him work on my S2 before and gladly left the Audi dealer that is full of young tdi part exangers, the old guys are all retired.
Back to diagnosis at 425.000Km, compression test done with:
cyl.1 - 12
cyl.2 - 12
cyl.3 - 11
cyl.4 - 11.5
cyl.5 - 12
nice numbers I guess, it needs and will get 4 new bisltein B6/B8 dampers which I´ve already bought, the ones in the car are still the originals, diff and gearbox supports but the engine ones are still original and good, one subframe support, all the other 7 are still good from factory, a master and slave cylinder and other smaller stuff, not bad considering the age and mileage.

So the Avant isn´t young anymore nor am I but its healthy and a testament to this cars build quality and the good care I´ve given it, next milestone will be the 500.000Km and I hope I´ll be back for many more milestone updates.

Thank you for reading!

I´m glad I helped.

Since reading this post I've been using Nivea on all my leather seats. The deep 24 hour moisturiser also works well on dried out leather. Top tip, thanks for posting. Has saved me a fortune on unnecessary, expensive leather creams.

My dad uses sun lotion on his '69 Jaguar seats. Kept them nice for years

Thanks for thorough responses gents, what a fascinating mod, and the resulting fuel economy (in $/km) effectively doubles! That must certainly help justify the initial cost, and perhaps hasten the pay-back period. I will go find a manual to read.

There's no pump, it just uses the pressure from the tank, plus a vaporiser to, well, vaporise it before it being injected into the engine.

The lpg ecus normally piggy back off the petrol system, adding a fudge factor to get the required injector opening time correct.

Tanks are heavy, very heavy... then add in 0.8kg per litre of added gas.

LPG doesn't really play too nicely with high boost, despite having higher octane.

A lot of the ecu manufacturers have manuals online for reading.

[psiconauta911]

So perhaps you have two entirely independent fuel systems providing an extra measure of reliability, - Yes

better than stock weight distribution when both tanks are full,- yes but is added wheight, +/- 80Kgs with the gaz deposit full

tremendous range potential before refueling is required,- double or near it

and maybe the capability for increased boost w/LPG if one wanted to pursue that? - easely done with an aftermarket ecu and a dedicated tuning since LPG is 120 octane, without that you loose around 10% to 15% of HP

Does the LPG require a fuel pump?- not sure but think so.

I don't imagine you can you switch fuels on the fly, can you? - yes via the on/off button but smoother if lift the gas pedal at the same time, it can also be programed to comute to gasoline at a choosen rpm

As the LPG's energy density may be lower, perhaps the increased economy you see Is due to a sales tax advantage when buying LPG vs. gasoline?- yes, since the the LPG as 25% less "caloric" power to go the same distance you usually spend that 25% more, I´m averaging 14L of LPG every 100KM and 1Lt of 98, in my calculation I´m driving around for half the price of runing 98 solo. (my country prices of course)

Thank you sir,

That is all so interesting and unobtrusive. Questions - So perhaps you have two entirely independent fuel systems providing an extra measure of reliability, better than stock weight distribution when both tanks are full, tremendous range potential before refueling is required, and maybe the capability for increased boost w/LPG if one wanted to pursue that?

Thank you Lago Blue.

Here are some pictures of the LPG:

Congratulations! Best listed car feature ever - "2 light bulbs in 24 years!" I know this kind of reliability is true (I've over 1/2 a million k on my Coupe). Sadly, in North America, they classify durable goods as consumer products that last 3 years. The embedded energy savings in not buying a new vehicle every 3 years or so has got to be a huge number also!

If you think of it, perhaps sometime you would post photos of what all the installed LPG gear looks like?

400.000Km and the S2 is still running strong!

[psiconauta911]

Somehow missed this Piscanought. Lovely car and good to read it's been so reliable.
There's something about the B4 chassis cars in that yours and mine
(20 years in a 80 2.6 avant) have been incredibly reliable.

I think it likes being driven instead of sleeping in the garage!

not bad for a 200k car
