OK, I have a 2.0d X type 06 plate with just under 100k on the clock. It has the electronic EGR. Recently I have been having a hot start problem. Run the car and park up for five ten mins then try to start the car and it chugs as if only firing on two cylinders and will not catch on the throttle. Switch off and back on and it might do it three or four times before it fires up. When it runs it is sweet no faults at all. Lots of talk about the EGR on here so I blanked it off with the blanking plate with the small hole. Still a problem. Took the EGR off and gave it a good clean which was amazing that the car was even running with the amount of cr*p in there. Still had the same problem.
Took it to my local garage which specialises in chipping cars and got them to check the ECU. It came up with an EGR fault code so I had them upgrade the ECU program, remove the EGR electronically and clear all the faults.
Drove the car away from the garage and it went like a train, pulled well and the economy was up. Got home and went in the house for an hour, came out to pop to the shops and car took three attempts to start. Still chugging. Once it was going the engine Management light had come back on.
Took it back to the garage this morning and they plugged it back in and there are no faults showing!!!!!!!
They cleared the ECU even though there were no faults showing and the engine management light went off.
Going to run it over the weekend to see if the fault comes back and then the garage is going to have another look on Wednesday.
Has anyone else had a problem of this nature and if so did they just sell the car on or did they get a fix for it. If they did get a fix what was the problem as we can't seem to find it.

From the workshop manual here are the possibilities.

Contaminated fuel
Air ingress
Blocked air cleaner
Blocked fuel filter
Low-pressure circuit
fault
Fuel metering valve
blocked/contaminated
Exhaust gas
recirculation (EGR) valve
fault
Fuel pressure sensor
fault
Intake air temperature
(IAT) sensor fault
Camshaft position
(CMP) sensor fault
Crankshaft position
(CKP) sensor fault
Injector(s)
fault/programming
Pump fault
Blocked catalyst
Valve train fault
Low compression

Take your pick from that lot.

Many have had the ECU software updated, to cure the hot-soak start problem. I had the same thing after I disconnected the battery, has taken about 10 days for the ECU to re-learn & now it's hot-starting again.

I had the same problem. Cleaned out the egr and the inlet manifold, updated the software. Went like a train! Sounds very familiar! The hot start problem went away for a few days and came back.

I gave up worrying about it, it always starts first turn of the starter, it just means sitting there for about 3 seconds until it roars into life.

I only seem to start with a hot engine about once a week, so I just live with it. It's slightly embarrassing if someone is listening, but no less embarrassing than the rattle coming from the auxilliary belt and air con.

BUT, if you fix it in an easy and cheap way, I'll have yet another go.

Good luck!

Thanks Roger but not very helpful. Most of the stuff on this list would cause a fault to come up on the ECU reader but there are no faults showing. The other suggestions such as contaminated fuel I will ignore as I buy my fuel from several sources across the south of England and they cannot all be the same and the others don't fit the scenario such as the blocked catalyst as this make make it happen every time and it does not. Car goes back in on Wednesday for further investigations so I will let you know what happens. If anyone else has had the same fault and cured it I would like to hear from them. I am leaning towards Injectors or just filthy engine bearing in mind the c*ap I had to clean out of the EGR and the inlet manifold. The same garage does an engine clean with Hydrogen being pumped into the inlet manifold which cleans the engine of all internal c*ap and carbon right through and out of the exhaust. Last resort but might be an idea.
