[bangty 1]

hi all my signum 1.9cdti 150 go's in to limp mode every 5mins of driveing it. i had it go in to limp mode last night and so i left it and hoped it was just a one off. so i started it this morning half way down the road limp mode agen so i just left it by side of the road. so heres a bit of history on my car i only use it around town and if it go's on a moterway its only for like 10mile and i never go over 70 my cars on 110k and my EGR valve was done at 98k car pulls fine untill it go's in to limp mode so anyone got clue what it could be thanx

hi Bangty,

sounds like a pressure loss - check all of the feeds to your Turbo and get someont to rev the car whilst you have your head under the bonnet

in the mean time do a "brake pedal test" to see if you can read the code of the stored fault - it may help us further mate

could be a split hose / hose popped off or even a small tear or pinhole

hi m8 brake pedal test how i do that ill go do it and get back to you?? as im sat next to the scrap

what hoses should i look at the to main big ones or are there more???

Get in
Press and hold both brake and accelerator pedals to the limit of their respective travels
Turn ignition key to Position 2, ie dash lights on
Release accelerator pedal
Re-depress accelerator pedal to the floor
Turn off ignition
Turn on ignition to position 2
The engine symbol on the dash will then begin to blink
There will be a sequence of flashes, separated by small pauses between numbers and a longer pause between separate fault codes.
The number of flashes needs to be counted and thus the 4 digit fault code can be determined.

EG, if the flash count goes as such
10 flashes
small pause
1 flash
small pause
1 flash
small pause
10 flashes

Longer pause

10 flashes
small pause
1 flash
small pause
10 flashes
small pause
10 flashes



Then there are 2 fault codes recorded and they are
0110 (ie 10,1,1,10 flash sequence)
and
0100 (ie 10,1,10,10 flash sequence)



Hope this helps


read the code first then we can point you in the direction of the hoses
