In een ander topic over zijn heel veel raakvlakken te zien

Zal kijken of ik foto's kan maken van waar je moet meten en wat de waardes
zouden moeten zijn

Fotos zouden echt fijn zijn elgriffo.
Wou proberen wat heftrucker had beschreven maar kwam ook niet echt verder omdat ik dat leiding van de blok niet heb kunnen vinden.
Nu het kouder wordt, maakt hij een bonkend geluid bij het starten wat echt van het filter en pomp huis vandaan komt. Dat doet hij dan bij het starten en tot dat hij op zijn gestationeerd toeren komt. Dan schud de hele auto en hoor je van rechts achter bonk bonk en als die op zijn toeren zit hoor je dat geluid niet meer.

ja inderdaad ik lees net het topic zelf , klinkt idd het zelfde !
zou het meschien ook met slechte of vieze injectoren te maken hebben meschien ,
die iets na lekken, of over een langere tijd wat lekken ,

al zijn die drukken ook zeer intresant denk ik , foto welkom :D

ik ga binnekort ook een nieuwe lmm potmeter bestellen op ebay , ga het gewoon proberen
300 euro bij Mercedes is me toch echt even te gortig ,

maar daar kom ik nog op terug als ie binnen is

Ik heb (voorlopig) slecht Nieuws, zoals een goede monteur beaamd is hij bij de basis begonnen, en stelde al snel vast dat het CO heeeeeeel erg arm stond. Ik heb deze zelf voor de vakantie met speciale apparatuur via de stekker op het linker binnenscherm afgesteld. :evil:
(ik heb een geregelde 3weg katalysator) . na het opnieuw juist afstellen van het CO starte de auto gedurende de hele dag warm, koud met tussenpozen van een half uur, uur en 2 uur , 30 min , 10 min nog een keer een uur als nieuw.

Ik ga het eerst even aan kijken want ik denk dat het probleem vooralsnog opgelost is

Ik had een foto belooft dus bij deze de S gerepareerd en gewassen voor de zaak :)

dus wat ik het zo nu snap ligt het aan zijn CO afstelling. Heb de auto nu 3 weken geleden in Zutphen af laten stellen waarna het probleem nog niet verholpen was.

Vond nog wat over de werking van een acumulator. 't Is wel in het Engels maar dat zal voor de meeste geen problemen opleveren hoop ik 8-)



"Often times the noise you hear can be a droan or a moan which is caused by a faulty fuel accumulator. It's a component that maintains constant pressure in the lines. It can either be leaking fuel or the inner diaphragm spring could be broken".

Fuel accumulator
The fuel accumulator maintains the pressure in the fuel system for a certain time after the engine has been switched off. When the engine is running it serves to deaden the noise of the electric fuel pump. After the engine has been switched off, the fuel accumulator maintains the pressure in the fuel system in order to facilitate re-starting, particularly when the engine is hot. The design of the accumulator housing is such that it deadens the noise from the fuel pump when the engine is running. The interior of the fuel accumulator is divided into two chambers by means of a diaphragm. One chamber serves as the accumulator volume for the fuel, the other chamber contains a spring. During operation the accumulator chamber is filled with fuel. This causes the diaphragm to bend back against the force of the spring until it is halted by the stops in the spring chamber. The diaphragm remains in this position, which corresponds to the maximum accumulator volume, as long as the engine is running.fuelaccu.jpg
