Classic Saab 9-5 (MY 1998-2010) / Tow Bar Electrics

« on: 03 September 2013, 03:16:56 PM »

Has anybody fitted a towbar to a 2002 estate and in the process of wiring up the tow bar electrics had to cut the wire that appears to link the two fog light wires on the tow bar electrics plug?

The bypass relay that came with the tow bar looks pretty comprehensive, but there are two red & white wires and they are linked in the Saab loom to the plug - as the kit is generic its not clear on where to cut.

Any experiences would be gratefully received!

Well - I finally got it sorted.

I drew out the whole system on paper and worked my way through it end to end. It possibly a culmination of things but the main culprit was the pipe at the end of the intercooler, it had come off just enough that I couldn't see it - but when I grabbed it to check it was firmly on I could pull it right away! I did remove and clean the MAFF as well so that may have helped.

Thanks for all the suggestions guys - I just didn't realise how much a small leak could affect how the car runs.

That's the pipe chaps.

I've just ordered some hose and one way valves to replace it to see if it improves things, though from what you say I don't think it could be the cause.

Going to have a good look at all the other hoses - I replaced all the small vacuum pipes so they shouldn't be a problem but I'm going to remove each one and check it through - just to be safe.

I'm starting to think it is something more sinister like the throttle body! I'll clean it and see what I find.

Thanks for the helps guys - if you think of anything else please do shout.

SGould - no not the brake servo pipe - though I have checked that.

This is the pipe that runs around the off side inner wing to the rear of the inlet manifold, under the back of the throttle body. I'm trying to find suitable pipe and valves to make a replacement...

I've checked the APC pipe connections and they are definitely on there correctly.

One pipe has my curiosity, on the pipe to the intake system from the APC there is a "T" piece, this connects to a pipe from the inlet manifold, which has some one way valves in it. This pipe is part rigid and runs along the inside of the inner wing - on the left hand side when looking at the engine bay from the front of the car. I've taken this pipe off and can't suck or blow from either end - so I'm wondering if this might at least be part of my problem.

Does anybody know what this pipe does and what the effect of a faulty valve or blockage could potentially be?

Thanks

Andy

Thanks for the update Handjammer.

You've given me something to think about now. Since the last problem I'm beginning to wonder if my intercooler could be a problem - maybe a hole from the massive over boost?

Everybody I've spoken to so far thinks it is a vacuum leak somewhere - this would certainly fall in to that category as the hole would be after the MASS unit.

I don't have a Saab specialist near me so am planning on getting in taken to one thats been recommended - but its over 100 miles away so its going to be interesting!

Will keep you all posted.

Hi guys,

I'm curious to find out what the fix was here?

I've just replaced my turbo on my 2002 2.3lpt auto - on start up it was fine, on test drive it was over boosting. It then went in to limp home mode.

I called the turbo supplier who asked my to remove the rubber pipe from the waste gate actuator and drive it to see if it still over boosted. Well it did - the gauge went straight in to the red, the fuel system shut down and the car coasted to a halt.

I restarted the car - it ran really rough - so I shut it off and refitted the pipe. Well - it barely runs - I can hold the revs at 1500 - 2000rpm but when I gently drop the revs it gets lumpy, the boost gauge goes in to the red and the engine stalls. This is an auto so it is undriveable.

Prior to removing the pipe I could drive it but had to be very careful how much I accelerated to keep the boost gauge out of the red. It was very peaky indeed!

Any suggestions?

As part of the turbo work I fitted the latest breather kit and replaced all the small rubber hoses with new silicon ones. I've checked they are all in the right places - which they are - I've also checked the pipes on the APC - they are all correct as well.

I'm thinking this is something to do with an air leak somewhere but I can't find it. The only thing I can think of is perhaps a damaged pipe in the wing - the bottom 2 brackets are broken off the airbox so by coincidence I suppose it could have moved and perhaps a pipe broke?

Any suggestions are extremely welcome!

Andy
