Hi all

I'm having trouble with my Saab 93 2.2 TID 2001, Basically the engine light is on, i assume in limp home mode??, it wont rev beyond 3000 rpm and some times struggles to rev at all. I have had it plugged in to a code reader which stated it was an EGR fault, but the guy said more likely to be a leaking pipe. So i replaced the EGR anyway but no luck still doing the same. I cleaned the sensor that goes into the top of the inlet manifold again no joy!

really starting to :cen: like :wall:

can anyone please suggest something else to try!!

If it was a pipe leak is their a "common" one that fails?

Regards

Neil

firstly im not expext , but was there just 1 code saying egr ? if you get a few codes it means 1 things wrong which is setting off others so dont immediately think its a massive job ..
i had P01100 & P0400 egr and mass air flow sensor , was going to change both but just did mass air flow which fixed the limp mode and stopped the light on the dash ..
you can check whether it is the egr by removing it ( but keep the wire connected ) and blanking off the hole .. i did mine http://twitpic.com/3wi5u5
if it's a vacuum pipe id say that the engine would sound ruff like a bag of spanners , have you noticed a change in engine sound ? check all the pipes as it only need a slight spit to set off and into limp mode ?
when did it go into limp mode , when the engine was under pressure ?
you say it struggles to sometimes rev unplug the mass air flow meter and see what that does .. clean the mass flow aswell, be carefull as it delicate, i used petrol with a toothbrush just to get the film/grease of it but others scorned me saying i should of used proper cleaner ... give it a try n see what happens
again mine went into limp mode and at 2.5/3000 rps in 3 and 4th gear and on the code reader it was bringing up 4 code faults, but all it turned out to be was the vacuum pipe detaching itself from the small plastic t piece, but once put back together the engine sounded a lot smoother
,oh ive just remembered its in limp mode so it'll have to go on a computer to reset it 1st

Again, not an expert by any means but I have had the same car as you for 5 years.

You've eliminated the EGR, so that's good, keep the old one and soak it in Parafin and give it a good clean, you'll need it one day.

As Dribbly says you also need to check the mass airflow sensor, and I also had the rubber intercooler pipe that runs from the turbo down to the bottom of the radiator split.

I think that's the most common ones. Other than that find a friendly specialist and ask the to check it with their Tech 2.

I hope this helps.

took the wire off the MAF sensor when it was ticking over, it didn't change anything ticked over the same!! also i think that the EGR was the only code!!

ok clean the mass air flow sensor , check hoses / pipes and you'll have to get the codes cleared n reset to see if cleaning the m.a.f made any difference ..
i might be scaremongering here but ..i chatted to the mechanic when mine was in for something n we were discussing how theses are troublesome engines and the egr valve being the most , he told me that the particle filter gets blocked which sets of the dash light n gives an egr code fault , so that could be 'a' problem .. if so, then it needs to be regenerated which means revving the nuts off if it for 10mins till it forces ( i think ) diesel down till it spits out sludge .. but sometimes they get so blocked you have to have a new filter ...
not saying it is but that's another possibility ..
p.s. should of said last night , disconnect the battery before you pull leads off ..
let us know how you get on n im sorry i carnt help you more , ive know how you feeling as ive had the same with mine

Hi Interested to hear how you get on mine did the same last week heading back up the M6 but with no lights on the dash. Would sit at 70mph no problem just slow getting there and no acceleration for overtaking.
I'm cleaning EGR etc today so will see how it goes next week.
Was your mpg effected I was still getting 44-45 mpg.
Don't know if its connected but my cruise control stopped working at the same time.
Hope you get it sorted regards Paul

code readers are just that , a reader that reads codes , it wont reset/clear the limp mode ... although i could be wrong
look in the local paper theres bound to be a mobile mechanic which does diagnostics who'll be cheaper than the garage and will prolly chuckin some advice for free

yeah you can get the ones that do both and more, some monitor car as you run the engine, but the one that resets light will do, i have an RAC OBD2 reader but wont pick up the car, yet read some posts saying some will, bit confused, just wanted someone to advise that had one that works on a similar model/year.

Hey Neil

I had a similar problem with my old 2.2, and it turned out to be the vacuum pipe that controls the turbo switch that had come off. I found the two ends of the narrow bore pipe had come apart at one of the connectors. Have a root around under the bonnet, nearside amongst the pipes and cables, you just never know!


Hope you get sorted

Neal :)

1. Even if the EGR is new, it doesn't mean the actuation of the EGR is working correctly
2. I had a similar problem of gutlessness but without the light and the code - this turned out to be a split hose on the manifold-feed side of the inlet. May be worth checking for leaks from the turbo to the manifold, including the intercooler (these, I am given to understand, being prone to splitting)

Not sure if you have the same engine layout, but on my 2003 car, it turned out to be a split in the short hose feeding the metal pipe that goes over the top of the engine. Replaced it with a chunk of turbo hose from a Pug406 HDi for £5 from a scrapper.

Check all vacuum pipes, probably best to just replace all with silicone. Similar problem last year on my 9-3 TiD was a vacuum leak.

If you post the error code (DTC), it will be simpler to help you.
About DTC reader, you need to post your engine code if you want help about it.
x22DTH ?
y22DTH ?

The error codes won't necessarily help. When I had the same problems, caused by a vacuum leak, the error codes pointed towards EGR valve and WAP sensor, both effect rather than cause. Once the leak was sorted out the error codes never came back.

The DTC will remain in memory until erased by user.
CEL will eventually go off with the repair, but the errors will be stored.

My mates rather expensive bit of kit erased the errors from the memory after we had traced and fixed the vacuum leak. 8)
