OK so I have a 2001 800 Special 1.9TD and was wondering if it had an ECU/VAGCOM.

I would look myself but its in the garage getting a new cambelt and service.

Any ideas? Wish I had have done more research before buying now!!!

Cheers,

Dan

The 1.9 has no ECU

1.9 is not ECU controlled, so no ECU:)

Tony beat me to it

OK not a problem I don't think.

Anything else missing from the 800 special I should know about, apart from some horsepower :cool:

Hi Dan,

Are you new to Veedubs, or have you followed the path to the T4?

I would say that the 1.9TD performance is on a par with the older 1.9 petrol T3 and 2.0 litre T2, but with 50% more economy. (Believe me - I've done the maths).

The 1.9TD is very responsive to diesel pump fine tuning (depending on it's condition) - just wait to see what it is like when you get it back from the garage.

Then, there are some basic freebie checks to do:

Check for kinks in the throttle cable (if yes a new cable is needed), and make sure the throttle lever opens fully when the pedal is pressed to the floor.

At the same time check the throttle spindle for diesel leaks - new spindle kits are available for fitting by Bosch diesel specialists.

Ditch the throttle damper on the pump, if it hasn't been dumped already.

Before embarking on the tuning route, make sure that the oil consumption is okay - the 1.9TD is a hard working revvy engine (unlike the 2.4D na) and van gearing (as opposed to Caravelle gearing) means it can red line through the gears.

If oil consumption is okay, as part of normal servicing, wean it onto 10/40, or even thinner 5/40 (as I use) synthetic oil (rather than 15/40), which doesn't sludge up like the others do. The latest diesel oils are low ash for EU4/5 Diesel Particulate Filters so they are even better - you still need to change the oil every 6K though.

Buy a turbo boost gauge and plumb it in - the boost can safely be wound up to 1 bar, from 0.7 bar...

If you're still not happy then an intercooler will help...

Some have blanked off their EGR valves and ditched their Cats for straight through pipes - I haven't felt the need to go that far, so my engine is still EU2 friendly...

Wow thanks for the replies.

I'm completely new to VDubs and will be getting my hands dirty to carry out the mods mentioned on your post.

Why not trawl - sorry search^ - through all the stuff on 1.9pp (for project power -emphasis on the lower case, there chaps and chapesses)...

Even so, you'll be lucky to break 90bhp (from 68bhp) with what I've told you, so far...

... otherwise ze van is gute, ya?

I'm pretty new to the forum, but some excellent info there on how to increase the 1.9TD power. I've got a 1.9TD and a 2.5 102bhp model - it's pretty hard going getting back in the 1.9 these days !! So you reckon the max that you'll get is 90bhp... still, gotta be better than 68 T:
