Yeah, my mechanic has been plugging in to read the codes too. I know the throttle actuator needed to be replaced because it was also making a lot of noise. But I replaced it with a used one, so that one may be bad. I'd just hate to replace it again because it's not a cheap fix!

BTW, should you ever decide to sell your 320, let me know!

make a small slice in the actuator cable close to the unit, and see if the wires are bare or have severe damage from engine heat destroying the insulation, when you buy a used actuator you likely are getting on in as bad shape as the one you are replacing, if the used one was working on the donor engine it is likely that once it is removed, the wires if they are burned will move and eventually touch, if they do they could eventually cause damage to the cruise control/ idle control module.

Thanks for the advise, guys!

I took my car to the mechanic's today and he ran the diagnostic on it. Came up as the throttle actuator again, so I will be replacing it with a refurbished unit rather than a used one. He said it was also causing the ticking noise from behind the passenger side of the dash.

Hope it works this time!!

As far as I know, there is no such thing as a refurbished unit.

Potomac German Auto, in Frederick MD sells refurbished units. I talked to them yesterday and they said that they send out used ones to be refurbished. The difference in cost is about $300.

Used: $425
Refurbished: $750 or so

I'm not sure what to do, as I've already bought a used one and had it installed, only to learn that it was also bad. It has a warrenty, but I'm out the cost of labor from my mechanic. I'd hate to have another used one go bad on me and lose the installation cost again!

So I have to decide on a used or refurbished unit. What do you think?

I would be incredibly hesitant to buy a refurbished unit.

One of the rearsons they fail is due to failure of the insulation of the wiring.

Jim F. has posted pics of what these look like opened up internally, and I would find it impossible for anyone to completely rewire the internals of one of these units.

. . late, Stefano, but take a look at MENU#24 on my web page. There's info that you should 'consider' BEFORE you do anything.

You guys are GREAT!!

I've decided not to go the extra bucks for a refurbished unit and will buy another used one for a lot less.

Jim F: thanks for the info. Luckily my car doesn't have the ASR, so it shoudn't be a factor.
