Tech2 Test Failed connection not established

[nwdaniel]

Ok, so I went to the garage for a tech2 test:

The EML comes on when driving down hill, depress the cluch and the revs drop to 0 and the engine stalls...restart the engine or bump start while still moving and the light goes off and normall service resumes.

When they plugged in the computer they couldn't get a response - the communication failed, the chap doing it suggested checking all the relays to the ECU and diagnostics ports.

So thats what I've gotta do tomorrow while sticking on some new allys, have another go at fixing the spedo (sender unit) & fitting a big bore back-box. any idea's on the EMS fault or why its not talking?

Thanks Guys/Gals

speedo will be the reason its cutting out... does it do it when comming up to roundabouts?

i have the connection problem with my 14xe... will be intreaged to find out whats up with it

small update -

The speedo cable had snapped (only 7 days old) again, so it looks like I may have put it in at too-sharp angle above the sender unit and I'll have to order another one and try again...
...also found a fauly earth (main engine strap) so thats to be done tomorrow

rich: yeas at high speeds to roundabout like bypass etc.

But it mainly happens going down hill

it will be your speedo and possible your EGR

u may need to clean it as it gets clogged up with carbon and sticks open
ii had the same problem

so i replaced it after about 1 hr ahah well annoyed me but my EGR made my car stall and die and splutter fixedd nowww

[nwdaniel]

Yeah, I replaced the snapped cable (tip: remove the air filter box to make installation easier ) and the spedo now works, touch-wood the light hasn't been on since so I think its fixed
