Hi I have a skoda octavia on 2010 which developed a problem almost randomly I have changed diesal low pressure pump ( in tank x 2 times) and high pressure pump ( in engine two times) also tested injectors for excessive leak bck cleaned fuel pressure rail ( due to initial suspect off shaving in high pressure pump) in case off shavings off old pump in system. Also changed two coolant sensors in engine.

 

The car when cold drives till the temp reaches about quarter. Then the coil light, management light and dpf regeneration light com on together  or randomly and car Cutts out.

 

Or will at times run for upto 30 odd miles  please can someone help who has experienced this or has dealt with this sort off issue would be grateful as I done timming belts, oil changes, fuel pumps, fuel filters etc. But to no avail.

 

Fuel pressure jumps up and down. Shows no code checked MAF sensors etc all fine no electrical faults fuel does not seems to circulate/return to tank.

@Danny2018 - Diesels don't have coil lights! The glow plug warning light (amber) has a picture of a coiled wire on it.

 

If the CEL light is coming on, then you must have a fault code. Do you have VCDS or just a generic "code reader"? In the latter case you need at least shareware VCDS.

Reply ment one for glow plugs andyes read with delphi noticed tonight my climatronic control are not displaying on my stereo screen and ac button is not turning my ac fan after replacing injectors back in car. Wonder if it is internal rather than engine compartment.

Hi if anybody else has this issue then please check crank sensor as mine didn't bring management light but a whole loada other know hopefully sorted thanks to anybody who replied.
