having done a search here & looking at the owners manual i was none the wiser in changing the rubber wiper blades...
having bought the wrong set of blades, i then went to a mb spare parts & garage and bought the correct bosch 4224 22inch blades... (AUD$18.00 each - even though they came in a pair packet - maybe the garage priced them that way to make it easier for them when replacing only one on customer's cars)
i removed the old ones and correctly fitted the new ones, but realised they didn't look right - as in the manual... there were no 'metal' strips in the rubber blades... so, i took the metal strips out from the old blades and , , , voila, , , success!!!
so, just in case, another benzworld and car newbie doesn't know "how to" change things, i thought i'd post this as well as attach a pic of the correct bits :)
How to install: reversing / parking sensor system. . .
for my 1990 420SE
just bought a "magic mirror" 4 sensor reversing / parking sensor system which comes with very easy / simple instructions...
my only problem is how best to run the connecting cable (keep it hidden) from the controller - in the boot to the led display mirror - which attaches onto the car's mirror...
instruction's diagram shows the cable travelling inside rear pillar and seemingly under the trim then to the front of the driver's trim and coming out near the rear vision mirror...
any suggestions / with or without photos would be appreciated as it would be a shame to waste $120 installation fee for something so simple...
Below is a list of links that will answer most questions about what rims will fit on a W126. the single most important thing to remember is that an offset (ET) of 25 or less is what the car calls for.
Here's a list of wheel widths and offsets that I wanted to add last night but couldn't get to format right. I think Talbir is the one to thank for the original list.
Per Factory Service manual V-8 Engine 116..96 & 117.96:
Checking electric activation of idle spead adjuster (ICV)
Engine - operating temperature.
Ignition switched on.
Pull coupling from idle speed adjuster and measure voltage.
Readout approx. 12v then
Checking regulation of control unit
Engine at idle at operating temp. Plug on couple at idle speed adjuster in a manner that voltage can be measured on plug.
Readout 5v +-1 then
Check idle speed adjuster
Engine at idle.
Simulate coolant temp <42 degree C, for this purpose pull coupling from temp switch and bridge. (located at rear passenger side on top of manifold)
Idle speed increases to approx. 750/min.
End of test
Any other values then those described above suggest a faulty control unit (located at firewall)
If a faulty control unit is found, nowhere within the Mercedes Manual does it suggest this method but others have suggested this and it worked for me. Remove the control unit cover and lightly twisting from side to side while engine is running. Idle should drop to normal speed once twisted in a manner that effects the potential poor solder union. Heat each and every connection, adding a bit of solder to each point. My idle is now on the money.
