106 diesel starting problems

[matthieus5s]

Hi all, Im new to this forum but I know what my spanners are for. My 1997 106 pug diesel tends to have a hot start problem. It wont start occasionally, but if its left for half an hour or so it starts as normal. Sometimes when cold its the same.

I know what your thinking, but Ive had all the glowplugs out & checked that they work & checked the voltage is getting to each of them, so that side of things are fine. I looked into the haynes book of lies & it pointed me towards a stop solinoid, but on my bosch unit i couldnt find one?? can any one point me in the right direction..Thanks.......

Could be the Immobiliser? After turning the engine over without starting, smell the exhaust. If the immobiliser is keeping the fuel off, there will be no smell of fuel or smoke.

To fix, take off the steering wheel covers and unclip transponder aerial assembly from ignition lock barrel. Open it up, clean and straighten the pins connecting the transponder aerial loop to the circuit board. File the housing a little and fix the board with blutack to ensure 2 pin connector is fully mated. Very lightly coat the pins with petroleum jelly - they tarnish.

Otherwise, replace transponder receiver unit.

Another possibility is that the fuel cut off is sticking. (Not sure why this should only happen when hot though.) Bosch ones are reliable and hard to replace, Valeo ones aren’t so good but much easier to replace/fix.
