The Check Engine light on my 1999 TDI Jackaroo came on recently. A visit to Dealer revealed that the throttle position switch needed replacement. This rang a bell so I checked Forum archives and found post 9470. In this post others with same problem were advocating doing nothing and some suggested removing sensor and cleaning it. Can anyone provide me with an update - did cleaning the sensor solve the problem and was it a big job?If I do nothing and light remains on how will I know if another fault develops? Dealer has quoted $250 to supply and fit repalcement.

Hows this,my check engine light came on last year on a weekend away. I left it until I got home. I lifted up the bonnet & checked the engine, & it was there!, closed the bonnet & the light had gone off!

Keith, The cleaning does work but it is reccomended that you use a non oily cleaner. Biggus Dickus Smithus sells some that work. Isopropal alchohol is good as it dries & leaves no residue. Try cleaning before you buy a new switch. One question... are you using an oiled foam aircleaner? This particular glitch seems more prevalent with Oiled Foam filtes than with paper... the theroy being that microscopic oil droplets contaminate the switch. $250 seems a good price for this replacement... most people are charged around $700 - $1000 for this the dealer will say he has to replace the whole throttle body in most of the cases if you check it out on this forum. Its a bit of a pain to get to it as its between the throttle body & fire wall. If cleaning dosent work drop me a line as I have a friend who may be able to get a genuine switch at a sensible price and you can replace it yourself.

Thanks Rick, I have access to Isopropyl alcohol so I wil give it a go this weekend. I'm not really sure what I am looking for though, can you describe the switch and it's locatrion and how to get to it?
I don't use an oil filled filter but do have an oil impregnated filter scck in the snorkel and admit to having used excessive oi when cleaning and reoiling it in the past!. The quote for replacement did seem reasonable compared to what others have been quoted. The Dealer(Melville Motors in Perth) did say that the switches alone have only just become available and that previously they have had to replace the entire throttle body at $900 plus fitting.
I am driving from Perth to Sunshine Coast next week so I want to have everything A1 before I leave.

if you can locate the throttle body, aluminium towards the rear of the motor with the large air line from the intercooler going into it you will find on that some black plastic components with the usual plug and socket arrangement. the sensor is in this area. I found it easier to remove the whole throttle body and then wash the internals of it. I had 2 problems with mine and the dealer told me that because I had replaced the paper air filter with the oiled foam one that I'd voided my waranty but the other problem was an overheating one... the check engine light dosent give very specific clues as to why its on...
In itself the cleaning is not difficult but it will takea good half hour to get all the other stuff out of the way so the job can be done, get the body off and clean the whole lot in Iso it won't hurt anything just ensure that all is dry before powering it up again. This worked for me but since going back to paper filter I havent had this problem again.

Onya Jackers.......my light has been on for 12 months and whole thing still running sweetly.....might clean it up and go back to paper filters (I am on the finafilter - that's what did it I'm sure) but do we have to pay Holden prices for the papers ?

"but do we have to pay Holden prices for the papers ?" No! $78 for an air filter is robbery.

I emailled sydney filters last week and they quoted me on filters.
Air (8971786100) A1081 $31.20
Oil (8971679720) MO024 $13.90
Bypass (8972093060) 1006 $ 3.95
Fuel (8943940791) MF177 $ 6.90

Plus GST

The brand of filters is Nippon Max & Cooper, which are of a high quality.
Freight to Hobart would be approx. $10-$15.

Their contact details are:
Sydney Filter Services P/L
Unit 1 / 24 Lidco St
Arndell Park 2148
www.sydfil@bigpond.com or info@sydneyfilters.com

I haven't bought any filters from them yet, I too have a finerfilter, and I haven't used these brands before so I can't comment on quality.

Same in my case, 99TDI with light on, holden said it was the TPS, $700+ to fix but leave it and she'll be right for a while.
HOWEVER a mate that works at holden (mechanic) came around the other day when I wasn't home and left a message that there is now a differant part available through holden (presumably just the faulty bit and not the entire tps) on the market for a lot less then the $700 originally quoted, this might be the $250 part someone was reffering to?
