Wheel alignment on an E38 must be done via lazer, dont go to a back street garage!!.
Cats, firstly I would get a smog test done to ascertain if the cats have gone as it seems very strange that both have gone ???? after the smog test go out on the high and give it a good 50mile blast at say 100mph, then redo your smog test and see what the difference is.
Airbag, check under the drivers seat that all the connections are tight, this sometimes happens if the drivers seat has been removed at some point, you could try disconnecting the battery for 20 minutes to reset the ECU, Neg off 1st and on last.
If you dont have the OBC screen, make sure you have the radio code it may or may not need a code.
The machanic is pointing his finger at the cats for being "clogged" and excessively restricting the flow of the exhaust and thereby limiting the free revving of the engine. In park the engine will wind up quite nicely, but under load it struggles somewhat. The car has just competed a 750 - 800km trip at highway speeds (120km/h) and returned what I consider to be fairly good fuel consumption figures of 8.8l/100km. Will the exhaust composition be different between a healthy cat and a defective one? Is there an easy way to test if the Oxygen sensor has joined the cats in the scrap yard?
Are there replacable bushes on the trailing arm, or is it one disposable item? Does the wheel alingment process involve the rear axel as well as the normal front end adjustment? In Australia I have heard this referred to thrust alignment, or is that something different?
I'll have a poke around under the drivers seat tomorrow and see if I can find any suspect connections. with the disconnection of the battery, do I need to have any codes etc for the car to operate? The vehicle has an OBC with GPS & TV rather than just the basic radio. How long do I leave the car to "reboot" once the battery is reconnected? Do the keys need to be in the ignition when the battery is reconnected?
Thanks for your help WS & M5
You do not need any codes for the car as you have the screen, if you are worried, take the + (red) cable off the battery for 20 minutes and then reconnect.
But the best way is to take both leads off.
The car will re-boot straight away.
Most people don't realise the E38 actually takes 16 minutes to shut completely down after you remove the key and lock the doors....Fact.
I was thinking u usually use the front bumper or the tire.... then I realized not the animal
The car doesn't burn oil does it? Cause sometimes the OSV dies and burning oil could foul the cats...
