What year is your 9-5? Mine is a US based 2003 Linear with Xenons. Do you think they would be the same?

 

Vehicle year is 2002. Neither WIS nor EPC list UK or US specific parts for the xenon system so I guess they're the same.

I can check when I get home in an hour or so.

 

Thank you

Hopefully this helps. My wiring is the same as yours and does not match my WIS diagrams either.

 

That is perfect. The sub-loom's now wired-up again. Thanks!

No problem, so many have helped me it's nice to have the opportunity to do the same.

 

I thought those suspension sensors were related to the stability control system. There is one in back too. Are they just for aiming the headlights?

 

EPC says they're "load angle sensors" and their (incorrect!) wiring diagram in the WIS comes under the heading of "Automatic headlamp beam adjustment, xenon headlamps".

However, there's no reason that the output from the sensors couldn't also be used by the ESP ECU to determine current vehicle behaviour such as pitch angle.

If the ESP ECU's as smart as the Trionic ECU then it probably even knows what you had to eat for lunch :lol:

ESP definately knows about lunch, but these sensors are only used for the headlights.

 

Hi everyone! I'm brand new to this forum - I came across it when I googled the problem I'm having with the Xenons on my 95 Aero.

Just to clarify - where exactly is this load angle sensor, and what does it look like? Does it tend to fail due to exposure to the elements? I'd like to have a look at this before I go to a Saab dealer, as those guys aren't cheap.

I'm getting the self levelling warning light on the dash, and the lights are pointing down to their lowest setting. The fault was intermittent, but is now permanent.

 

Welcome to SaabCentral Mark

The front load angle sensor is mounted on the bottom of the steering knuckle on the right-hand side of the vehicle. A rod with a ball and socket joint at each end joins the sensor to the suspension control arm.

Remove the front wheel and look at the leading edge of the suspension arm. You'll see the rod pushed onto a ball that's screwed into the arm. The rod's connected to another ball joint on the end of a lever that's on the sensor.

You can probably see the sensor if you put the steering on full right-hand lock.

The connector for the sensor is one of Saab's usual weather-proof jobbies with an extra rubber boot protecting.

The wire for the sensor runs through a rubber grommet in the wheel arch and then connects to the main loom inside the engine bay with another weatherproof connector. You will be able to see the grommet in the arch with a torch. A green brake pipe runs through the same grommet.

You really can't miss it but if you do then let us know and we'll provide more clues

Has any work been done on the car that may have strained the cable to the sensor?

Thanks Matthew.

I've had a good old read of the posts here, and the other info available on the net, about these cars and their potential for the engine to sludge up and die - and I'm cacking myself about mine now!

It has 71000 on the clock, and oil changes have been every 10000 miles, but I have no idea what oil has been used. I've had it 2 years now, and it's worth less than the finance on it, but I could hand it back and walk away now while it's all OK, and start afresh with another car that isn't a time bomb! Pity, as it's been reliable for the 2 years I've had it, and it's well loaded too - perforated leather with cooling fans, Sat Nav, Xenons, heated REAR seats etc! Good looking thing too, in that Electric Blue or whatever it's called.

Any thoughts from anyone? The car is going in for an oil and filter change tomorrow, and hopefully a new sensor.

 

Every 10,000 is a disaster for these cars. Lots of variables but dropping the pan is the only way to know for sure.

 

I know this now, but I reckon there are a lot of Saab 9-5 owners out there who don't - after all, what percentage of car owners join clubs or forums connected with their daily driver?

The car has been serviced at Saab Main Dealers all it's life - Why would they not inform me of this? My Dealer told me when I bought the car that every 10000 was the way to go. I'm raging.

Oh well, never mind - It can go back to the Finance Company now, before anything goes tits up. I feel something better designed coming on, like an Audi, Volvo, Mercedes or BMW. I have an old BMW here that's as reliable as rain in Scotland - a 1996 525i. No sludge, no engine trouble at all.

We had Saabs in the family years ago which were great - a 900 EMS and 3 900 Turbos, plus a couple of 9000's for good measure. My little Bro still drives a 1986 Turbo - they built them properly then! Maybe closing the book on Saab now is the way to go after all.

 

This is now completely off-topic now but I can understand your frustration. All Saab owners that have cars affected by the sludging issue received a letter from Saab/GM outlinging the problem and recommending a change to the owner manuals oil change interval. These same cars had the warrenty extended to 80000 miles. This is a pretty standard response from Saab and in line with other manufacturers. Toyota also suffered from sludging as well. They handled it in a similar fashion. I have a friend with BMW's of similar years and they have the same if not more issues with their cars. My friend just spent 6000 on a new motor because the cheap water pump BMW uses broke apart and destroyed his motor. This is common on BMWs. The previous owner should have revealed the letter that they received.

Where I will agree is the complete dishonesty of Saab dealers.My dealer is the same way. Even after showing them the letter they insist 10000 is ok. This is something that Spyker/Saab can hopefully fix.

 

Drop and clean out the sump and have the main and big-end bearings inspected. If all is well then fit a new PCV kit and run the engine on quality fully synthetic oil, changed every 6K. The engine should then be fine.

The B235 engines do use the oil and you must check it frequently. Don't rely on the dashboard oil pressure lamp to warn you when the oil level's low because it illuminates only when most oil pressure has gone and it's already too late.

I know 9-5s are far from perfect but I wouldn't be without mine. There's still enough proper Saab in them to make other vehicles ordinary and dull.

OK - an update to this.

The car was at the dealership yesterday for a service, and to have the Xenon lights attended to. The bad news was that their Tech 2 system was down, so they couldn't deal with the sensor problem, and in any case, there is apparently a backlog of these on order at the moment.

Good news is that, after voicing my concerns about the other issues, they dropped the sump and checked everything over, as well as investigating the car's history. Turns out that it has always been run on fully synthetic oil, the breather system has had some kind of upgrade, and there are no sludge issues. Total bill? £149.00!! Result!

So - I won't now be handing the car back to the finance company!

All I need now is to get my lights sorted out - they said it would probably be another 2 weeks before it can be done, so I'll just wait until Feb 24th and get the MOT done at the same time, for which, I'm told, nothing will be needed - for the second time in a row! :cheesy::cheesy:

Thanks for the replies lads!

 

A few pics of the car then, now that all is well again!! Sorry if these are in the wrong place -
Admins / Mods - can you move the post to wherever it should be?
