1.9 JTD/Saab Tid Problems

Having problems with a Saab Tid engine, same as the 1.9 JTD so hopefuuly some of you wise folk will be able to help...

2006 9-3 1.9Tid (120) 122,000 Miles (Same as the 1.9 JTD 8V)

Cold Starting - Very lazy starting in the morning and at 5pm after work. 10+ seconds to fire. Coughs and splutters for ages but always eventually starts. It's been getting worse for the last 18 months and no one can figure it out. Occasionally it comes up with the "water in fuel, contact service" on the SID but not always.

Once started - Sweet as a nut. Perfect idle, good performance, 50 - 60mpg on the SID and no smoke whatsoever. Has never missed a beat.

Warm Starting - Much Better but not perfect even after an hour on the road doing 50+mph. It just has a brief splutter before catching. Not quite normal.

Work carried out:

Battery Replaced
Glow Plugs Replaced
Leak back pipes replaced
EGR Valve cleaned out checked valve working (Twice)
DPF Regenerated (this was almost two years ago. It helped for a while but then got worse and worse)
Fully serviced
Diesel filter checked for leaks
Full diagnostics with no faults picked up
Just got it back from a Diesel Specialist who checked fuel pressure, Crank Sensor, etc. He said there is a slight fuel leak around 3 of the 4 injectors but he didnt think this would cause the problem. Ended up saying he had run out of ideas and gave it back! I asked him if the injector seals/washers would cause these symptoms and he said no.

I'm at my wit's end with this now, any help much appreciated.

Thanks for reading.

Have you tried plugging it in to a laptop and resetting the ECU so it relearns variables? Have you tested the MAF air flow sensor, maybe the electronic choke is running lean on start up? Mostly guess work here I'm afraid matey.

Hi, how slow is it to turn over before it catches.? with a new battery it should spin over quickly, if not then you could have an engine earth problem.
My car was always quite slow to turn over but I thought that was just how it was as the battery was new, then in the summer the earth cable failed completely, now with the replacement and the temporary earth cable still in place it spins over much quicker and starts straight away.. Try putting a jump lead from the battery negative directly to the engine, on a lifting eye or similar.

These diesels run at super hi pressure so if there is a leak at the injectors it will not help starting even if it is small. Injectors can also fail but it is quite rare. If they are leaking back I could see that as a starting issue too. Might also be worth getting a compression test done at the same time. Low compression will also cause lazy starting. Hope that helps

Try replacing fuel pump relay. My 2.4 was suffering from this and then finally wouldn't start at all. The relay was found to be faulty along with the main control relay. Replaced these and now fires up instantly.

This thread is over a year old! If he's not solved it by now he's probably got rid
