Coincidence?
I tried out a new ebay purchased KKL USB cable on my 2004 1.9JTD Multiwagon the other day but couldn't get it to connect (installed okay on the PC and ran multiecuscan software).
Nevermind I thought and went back inside.

Next day when I drove the car - half power. Floored the throttle and the engine lamp came on.
Never had any engine issues in nearly 2years ownership.
What do you reckon please? Just a regular fault or could connecting the KKL interface cable rogered something?

Many thanks for any ideas, Ian


The error messages I got were:

Just a coincidence, amazing that it should play up directly after plugging in a diag lead!:bang:

It's the Wastegate Vacuum Switch evidently...

Is that a Fiat part - DIY or garage fit?

Just had it into DTM spealists in Bristol this morning Thursday6th .

Thanks, Ian

JTD engine has a variable geometry turbo, it doesn't have a wastegate.

Re: Coincidence? No vacuum to wastegate

Just wiki'ed variable geometry turbo - you're right, thanks for pointing that out.Looking on the invoice for the diagnostics it says:They said it was a FIAT only part and couldn't get one until the next day. As we live 30miles away we brought the car away again. I'll query it...
Cheers, Ian

Re: Coincidence? No vacuum to wastegate

The vanes in the turbo are adjusted by a vacuum operated diaphragm mounted on the turbo. Many people, including garage staff, mistake this for a wastegate. Vacuum to the diphragm is controlled by an electrically operated boost control valve. This is probably what your garage means by "turbo switching valve".

The boost control valve on early Stilos was mounted low down under the left headlamp where it was [FONT=&quot]susceptible to water ingress to the valve and/or it's electrical connector. A later modification moved it to the side of the battery box to avoid water ingress.

You could try disconnecting a cleaning the connecter with electrical contact cleaner, but if yours is still mounted low down, it will be difficult to get to.

If you need a new valve, there's a new original Fiat one for £75 here: http://www.ebay.co.uk/itm/110794990356?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 They are also available as an aftermarket part for about £45.

Diagram below shows it's new position on the side of the battery box. Fiat supplied a bracket for the modification. I fitted mine without the bracket.

Cool - thanks for that.
The engine lamp is on and I currently have no access to diagnostics (see error msg above).
If I were to try the contact cleaner and was lucky enough to fix it, would the fault need to be manually cleared/reset to get the engine out of limp mode or is it smart enough to see the part is working, use it and clear the fault/lamp by itself? CheersTa, Ian

Once the problem has been fixed, Stilo engine faults self clear after 3 clear runs.

Thanks very much Davern!

Sorted and at half the original cost - got the ebay item at £75 and my local garage charged £40 to change the solenoid and resite onto the battery tray. Hopefully that should put it at bay for a while.
Cheers, Ian

Hope they haven't left the two fixing poking too far into the battery box. There could be a danger of then penetrating the battery if you have a full size one. I fitted the bolts from the inside and there was still only a small gap between the bolt heads and the side of the battery.
