Ok so I'll start at the beginning.
The vehicle is a 2003 with a 1.9JTD engine, it's covered 262500 miles and drove ok'ish a bit down on power and a bit of black smoke.
The clutch had a very low biting point and when the water pump started getting noisy I decided to pull the engine and gearbox out and give it a bit of TLC.
The inlet manifold was full of crud about 10mm thick all around and when I took it off I could see the valves and ports were just the same so I took the head off took the valves out and cleaned and decarbonised everything,
Rebuilt it with full head set, new water pump, timing belt kit, nice clean inlet manifold, EGR cleaned, breather pipes cleaned, boost pipes cleaned, intercooler cleaned, new clutch and refitted it all back to the car.
All was good with the world it ran brilliantly, loads smoother, lots more power.
3 or 4 weeks later the management light came on, ran diagnostics and turned out to be the MAP sensor, replaced the sensor and all was well again.
A couple of days after this I went out and it was running brilliantly, stopped at a shop got back in and it had gone into limp mode, won't rev over 3000 rpm and some grey smoke when I try to get it to rev,
I have ran the diagnostics again but there are no codes found,
Checked all the vacuum pipes, checked boost pipes, checked fuel filter, checked MAF, took EGR off to make sure it hadn't clogged, what more can I check??
Any ideas anyone?
If it hadn't have been for sentimental reasons I would never have thrown so much money at a car thats probably worth less than I've spent on parts but I'm too far invested in it now I can't just leave it so if anyone has ay ideas I'd be very grateful of any advice.
