Title: 2.5TD Limp Home Mode
Post by: francais on 06 September 2010, 11:21:41

Hi


Thanks for the welcome.


I have a LHD 2002 Opel 2.5TD (BMW Engine) 5 speed auto Estate.

Had the car for 5 years, it's done 140,000 miles and since having a new engine (2 actually but it's a looong story!!) it's been running well until a couple of weeks ago. It decided to go into limp home mode, very annoying as I was a log way from home.

Anyway, got it back and did some reseach on the net and came up with low gearbox oil as the most like cause. Took it to a local garage (not VX) who said they think it may be throttle sensor. VX want 260€ for a new one! They took the complete pedal assembly off and I brought it home to try and find a new one. Opened it up to find that there is a pronted circuit with a couple of carbon tracks that it the throttle sensor position. Put my meter on the tracks and they seem fine. Thought I would try and find a new pcb - dead easy to fit. But seems that the LHD pedal is different to the UK version - surprise surpise!

So my question is this:

Does anyone know what resistance I should see on the carbon track? Can I get a new PCB and if so, where?

Are there any other common cause of limp home mode?

Thanks all.

Tim

Lots of causes of limp home. It really, really, really needs a proper code reader on it, complete with an operator who understands it

It might be worth doing paperclip test to see if anything shows up:

If you have no means to get a code reader on to it.
