MERECDES E320 CDi 1999 (UK)

Hi! Y’all. Thanks for your help so far.

My main problems seem to have been resolved with the change of the Air
Mass Sensor.

From time to time still getting;

Code 130 CAN comms with control unit N15/5 (electronic selector lever
module control unit) intermittent disturbance

and

Code :P1856-005 Selector lever position detection failed.

and

Code: P1664-002 Electric Heater Booster equipment fault

.... MB letting these ride for a while to check if they return.

The main thing I notice is that the cruise control backs off suddenly
when at speeds over 55 mph .... it will set .... run for a while ...
then suddenly back off .... resume and reset both get it back again
... but if you try this too many times it backs off totally and will
not set .... until you switch of and start again.

Still the best car I have ever had ... when it goes it goes great!

Thanks again all/any ideas welcome.

You say it "backs off" - you mean it quits and needs to be reset or
falls back to some lower speed?

If it simply quits I'd suspect its circuit board has a cracked solder
connection. But check its fuse before doing anything with the CC unit.

There are CC rebuilders who know these components and can repair them.

Are you referring to some W124 type of CC repair? This is a W210, a modern
car and I don't think it would have a separate circuit board for CC and if
the computer(s) taking care of the CC functionality would have circuit board
issues, the car should have problems running generally. Please clarify if
you are familiar with this W210 issue.

I checked with someone who knows about the modern CC systems. The new CC
function is integrated into the engine control system. So, in this
owner's car, the engine codes should lead to the CC fault.

Hi!

UK 1999 E320 CDi model diesel 3200ltr engine

It quits ...and needs reset or resume ...you can repeat this a few
times before it quits totally....OK (with same fault) after switch
off/on of engine.

This currently ... is the only known permanent problem ...

... as if one of the sensors involved in CC is unhappy ...do we know
all those involved ....got brake pedal switch got air mass sensor
.what else?

MB saying connected with fault codes but they are not permanent
