Top 20 1999 Mercedes-Benz E-Class Questions & Answers

Question edited for a lot more clarity. Question moved to model category. Did you have the radio or CD on when you were doing all this work? Low battery voltage can cause it along with other reasons. https://www.google.com/search?q=1999+E320+BAS+ASR+light+on ..

have you check the gearbox oil level / last gearbox oil service

There may be a wiring issue that goes to the component causing the P (powertrain) code to set, however the component itself may be just fine although it may not be sending a return signal back to the PCM causing mis-information to set the code. I would take it to the dealer before further funds are mis-appropriated.

One possibility is a blocked fuel line or filter. It basically runs out of fuel and you have to wait for it to come through slowly. The other possibility is the ignition system is losing spark as something heats up. You have to wait until it's cooled down before it runs again.

Can you hear it the petrol pump you might need to remove the fuel inlet pipe to see if there is any fuel getting to the engine or the return fuel pipe there should be fuel either way if there is fuel remove 1 plug keep the leed atached and use some insulating plyers to keep a hold of it place the electrode on a bit of the engine to see if you have spark as long asvyou have these 2 things it should start

check the fuel pressure , if your car is kompressor , check the air temperature for overheating

Most likely the oil pan gasket or timing cover gadket. How much oil did you put in it when you changed the oil? Did you over fill it?

Only if your about 4 years old its very small there is a metal bulk head behind the seat with just this small gap for skies wood ect

common problem with them at that mileage -change the gaskets

check connector --wiring harness --ground--for short or fray but most likely connector will be problem

Most manufacturers will install a cable in the trunk on the fill side to pull for manual release. It may be in sight or possibly behind a panel. Owners manual should give instructions as well

A battery at 9.46V is weakening. 5 days of just at idle may have brought the voltage down some if there where any lights, heater/ac,alarm system or another type of short. Possibly a dirty or bad battery connector at the battery change was the cause & the booster cable clamp solved the problem. After the boost did the idle go up any? The 14.26 is the sign of a good working alternator. I would double check those battery cables first GOOD LUCK< FRANK M

Daryl, fuse #59 in the driver's side fuse box under the hood powers your starter relay. Attached is a pic of your starter relay, which could also be the reason your starter isn't engaging. Also check the fuse for your starter relay and it's holder (polish off deposits)

You will get hosed because it is a Mercedes. Regular cars runs about 200 dollars but .......................

The batteries in the key don't have anything to do with its ability to start the car. Try turning the key to the run position several times before starting the car. This will get the fuel pump running and build pressure in the fuel system. If this technique works you are looking at a fuel pressure leak when the car is off. If the problem only happens when the engine is hot, you likely have a failing crankshaft position sensor. Beyond that, I can't help without the car in front of me for testing.

It is gearbox problem,could be oil level issue,please check level first.

if the air suspension is going down its one of 2 things either the pump is going but then the doors ect wouldn't work or you have a leak on the system very expensive to replace cheaper to replace shocks with standard ones

Hi, It is more than likely the interior sensor, it is in the roof panel if it is an MB factory alarm, or on the dash if not! you need to get it tested, if you can cover it with tape and set your alarm to see if it goes off, hope this helps

most fuses are in the engine bay depending on what side the steering wheel is it should be in the engine bay just under windscreen when you take the lid off the fuse box under the lid there should be a plan telling you where each fuse is located on the board

We have had check engine lights on all vehicles for 35 years--so why the question? Check for OBD Codes,look them up & diagnose them
