[1340paul]

hello to all
first time here,
i am thinking of buying a scanner not pc type,
there are so many out there can you recomend one for faults resets etc.
is my car obd2 only had it a couple of weeks and ecu gone down, no spark on 2&3 changed coil checked wires, i had a test done it came up with codes 042 043 but i now believe i did not need the coil so i am hopping to save money buy the purchase.
many thanks
paul

dont think so

I do not recognize those code numbers it depends on what they were read on,,but i will look in the morning

 

[kth286]

It is not OBD2.

According to my code list for the PMS system the following show:

042 injectors

043 injectors


So check the injector plugs are fitted on correctly

The ignition codes for coil circuit to cylinders 2&3 are:

065
066
067

injectors

would a fault on the injectors cut the output on the coil.
cheers paul

 

[roofless]

have you replaced the pms or just the coils

 

[television]

would a fault on the injectors cut the output on the coil.
cheers paul

Not unless the ECU was damaged

 

[1340paul]

only one coil replaced

i have only replaced one coil as i do not know a lot about these, first mercedes i have owned, please bare with me where do i find PMS?

latest news on c200

the man came out today with his test equipment,
silly me disconected the battery the other day connected it back up and guess what no code faults came up.
man done some other tests all came back to ecu,
he has taken it away to test it he will let me know the verdict tommorow. if it is what he thinks it is he may be able to repair.
will let you know tommorow.

you might get one from a salvage yard if it's a exspensive repair ?

 

[1340paul]

been quoted £375 for one, but just waiting for results of test.
£375 is the cheepest i have found so far.

[dave.robbo]

Do you know anyone with the same car? Just thought you may be able to borrow one for a test..

Scanners are a total waste of money. Some scanners don't even display the codes even it there.

Buy a proper MB STAR 2008, set you back £500 plus a 44-pin IDE harddisk interface laptop(T20-23, 30, some even supply whatever you wanted by telling them the laptop you wish to use it with) but worth it.

that will give you a good idea if the repair is an option but i would try more yards & ask for a pms unit dont say ecu as they will up the price.if you find a older syle yard & remove the part your self you might get lucky

 

[1340paul]

had a phone call about ecu
the man cannot fix it himself so has sent it away to somewhere he always uses, he will then come back to me with a repair price i would think monday.ecu is at fault.

scanner

thanks for your info on this,
i have been looking at a snap on item as i need it to cover other models,
it is an mt2500 if anyone has any knowledge on these before i purchase.
does the star only cover mercedes?
one more question,
i now have two new coils
new plugs
i am going to replace the leads, mine are straight leads but i am not sure wether these are correct, as they are also shown with a right angle lead,
so not sure which is correct straight or angle, (coils under manifold).
cheers paul
