Went and got the following codes retrieved from my 1999 MB E430: Po753, po758, p0763, p0130, p0715, p0305, po306, po301?

SOURCE: Radio Code for 1999 Mercedes E430

If you call your merc dealer they should give it to you on the phone, if not have a look at this web site, if not, then if you take out the unit and let me know the s/no: i will see i have it.

po 753 Shift solenoid A electrical problem po758Shift solenoid B electrical problem hope this helps

SOURCE: where do i locate my vechicle speed sensor on 99

Take the car to autozone. They will do a free scan and tell you what the codes mean.

SOURCE: TROUBLE CODES PO301 & PO306 HAVE ALREADY

P0301 = Cyl no 1
P0306 = Cyl no 6

If you have changed plugs and leads and confident that they are now ok you need to run a compression check on all the cylinders, I'd emagine they should all be running at approximately 150psi per bore, if 1 & 6 are down it could be the head gasket, timing or piston rings.

PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...
