You have permanent all wheel drive dude. The system is always ready to go. If you want to do some offroading, activate the "off road" button that looks like a vehicle climbing uphill on the lower, center dash panel. This will allow more slip for the traction control system and hold lower gears longer in the trans

Hello I'm an M.B. tech- lot's of people have had dificulty with that code. The code means just what it means insuficiant air flow. The egr system does the same thing. What generaly ends up being the problem is a clogged port in the engine head. Unfortunatly on the air pump the port is near the exhaust side of the deck and you must remove the head to repair it where as the egr you can clean the port at the throttle motor. First thing you need to do is make sure there are no more codes in the system. The way that the ecu moniters the operation of the air pump is map senser for vac to the switcthover valve which is the same switch over valve for the egr located in the front of the cam cover. Next it will use the front o2s to moniter the airflow. Also it moniters the airpump relay operation. Operation is started during open loop by the coolant temp. senser. I beleive that this vehicle could possibly have a diagnostic mod along with the engine ecu which moniters the ecu performance. This also needs to be scanned for codes, They discontinued these in late 95. Make sure you have source vac, to the switchover valve-next moniter switchover valve otlet to diverter valve during air pump operation. To properly moniter o2 sensers you will need the proper equipment. Inspect all the airpump plumming as well. assuming the air pump is getting power and operating properly. I would recommend taking the vehicle to an M.B. repair shop and have the system function tested and scanned-with a flow check for the clogged air injection ports. Depending on how many miles I would just do a valve job. If you have any more questions just post and I will get back to you

over 80% of mercedes ever made are still on the road in use,only volvo can beat this fact with over 90%.
keep it serviced at 10k intervals,and it should last 30 plus years.
bodywork is galvanised,so look after paintwork(1 dent/scratch will knock over $1000 off the price...)only buy if full leather and keep it fed.
