bmw dis gt1

[stewartcampbell]

Hi guys have a big problem, my 1999 bmw 320d died while driving at about 60mph about a week ago and has not started since.The car has been in the garage since monday and the only fault codes are glow plug circuit and something to do with the clutch, clutch switch or something (but car has neither cruise control nor do you need to depress the clutch to start)The garage has just about given up with it as first they found no power at the fuel pump in the tank and after using a wire to get the in tank pump working now there is no pressure at the injectors.The nearest bmw garage dealer or independent is over 100 miles away so would not be financially viable to have it towed there.I wouldnt mind but i spent over £2000 getting a new turbo and the engine rebuilt about 6 months ago, my question is would it be worth buying the bmw dis software from ebay,how do you hook it up to the laptop as they seem to use a com port which seems quite rare on laptops.Can you use a comport adapter, would it be likely to read codes other than the ones the garages scanner has and can you read live data from it as if not the car will prob have to be scrapped.

Get yourself one of these: http://bmtechnic.co.uk

Piece of p* to install and is a normal USB cable so likely to work on your laptop. Has all the software you require (I should think so), and great support on the m3cutters forums.

will this do all that dis does and is it any more likely to point to something than a generic diagnostic scanner, thanks.

[stewartcampbell]

The fault thats coming out on a bosch diagnostic scanner is (8 main preheating relay signal improbable) anyone know what this means?

[stewartcampbell]

Got the bmw technic software and have scanned the car and there are quite a few fault codes but most not relating to the non starting so i will just list the one that i think could be the problem, in the in the fault codes
10 dde: Power supply undershot fault frequency 48.
In the dis test schedule it has come up as
DDE - 10 DDE Power supply - DDE voltage undershot - -- - -- - Currently not present - -- - 1.at:engine speed 0.0
? DDE main relay B1361__D3REL
=> Positive and ground supply B1361_D3UBH
When i test it it just sort of goes round in a loop checking the battery voltage asking if the setpoint has been reached then asking to start the engine which i cant do, does nothing if i just crank it.So does this mean a power supply issue to the dde or do i need a new dde, im guessing these are coded to the car so can these be coded using the bmw tech software?

Yes you can do code modules using the bmtechnic software.

Don't know how though!!

I would suggest this would be question better asked on a BMW/model specific forum.

Do you have a diesel specialist nearby? Might be worth a phonecall.

You can programme DDE using SSS Progman.

just found this http://www.ebay.co.uk/itm/BMW-320D- ... 2a28f32b4f , could this be my problem with my fault code?Should of said earlier it is also showing a fault with the glowplug system.

[stewartcampbell]

sorry that liks not working, here it is http://www.ebay.co.uk/itm/BMW-320D-136HP-DIESEL-FU...

It may be the problem but I'd recommend some more diagnosis before buying it. If I get a chance I'll dig out my M47 training notes.

Join the AA with homestart and relay ?

[helix402]

I've looked through the training folder, fuse 1+2 in the engine bay supply the DDE relay, F29 is the DDE ignition feed. DIS should lead you through a test plan to sort the problem. If you want any more tips drop me an e-mail.

Deleted the fault code memory and restarted the test and the faults listed are (leaving out ones that i know are not relevant, no idea what the first few are
INSTRUMENT - F6 KOMBI:No CAN identification (DME) Open circuit Currently not present
INSTRUMENT - F7 KOMBI:No CAN identification (DME) Open circuit Currently not present
INSTRUMENT - F8 KOMBI:No CAN identification (DME) Open circuit Currently not present
? CAN bus, instrument cluster B8442_00001
INSTRUMENT - D7 KOMBI:Tank lever-type sensor 2 - short circuit to positive currently not present
?Fuel gauge B6213_00005
DDE - 08 DDE:Glow plug system Glow plugs or glow-duration relays faulty - Currently present
Inccidentaly when going through a test schedule for No engine start possible it ran a clutch switch test which said to operate and not operate alternatively and displayed no operated throughout even when i was so does this mean anything, why would this car with no cruise control or depress clutch to start have a clutch switch?, thanks guys.

[helix402]

The first few faults relate to the instrument cluster, saying it is not getting data from the DDE via the canbus. I think the clutch switch fault may be a red herring.

[stewartcampbell]

Yes i thought that about the clutch switch to as it would seem to serve no function, does this car even have one.So is it possible i need a new engine ecu dde.Can these be programmed more than once so i can buy a secondhand unit and could i code it myself bmw technic software?

[stewartcampbell]

only reason i mentioned the clutch switch is it was when i put the clutch in to change gear that it died.

[helix402]

A used DDE can be reprogrammed, it will also need to be aligned with the ews. If you haven't done it before it could be tricky. For all reprogramming you need a good battery charger. Have you tried looking at the status list on DDE? This gives actual and desired values for things such as rail pressure. It might help to pinpoint the fault. Re the clutch switch I can't remember if the E46 such as yours has one, I never seen any problems with them. If you want to look into the clutch switch DIS should show the location if fitted. If one is fitted you could bridge it to rule it out.

[helix402]

I've checked the parts cd for your car and a clutch switch is listed, seems to be on the side of the master cylinder.

[stewartcampbell]

Cheers for the info, there is no fuel rail on this one its pre commonrail 136hp so not sure what values i can check realy without the engine running, just so happens i was using this feature on my father inlaws 318ci tonight, got a shot of it to use for a while, it has a missfire and now i have the software anyway thought id check it out, turned out that the 2nd lambda is showing no reading even though no fault is stored for this, other thing was the fault it did come up with was dme not yet programed.

[stewartcampbell]

Found the clutch switch, its on the pedal, dont suppose you know which pins to bridge on the plug, iv got a yellow and purple a yellow and brown and a blue wire going in?thanks.
