Hi all
Thank god I found your forum. Have found some good info and given me a sense of direction! Still have a problem tho and would love to have some advice from some better minds than mine! Would really appreciate some help.
Bought a Signum 1.9 CDTi (2006) about 4 months ago and was delighted with it. It now has 109K on the clock but its the only way I would afford a facelift model!
Problem started 2 weeks ago, loss of power at times, drove like it had 'lumpy' fuel in it. Popped to the local garage who put some 'gunk' in the tank but it made no difference.
Problem was getting worse and the spanner light came on so back to the garage. They had a new Solus Pro machine and read error code P2279 (intake air system leak). They cleared the code and put more 'gunk' in the tank.
No improvement.
Back to the garage but they couldn't find a leak in the hoses. When carrying out the throttle solenoid valve test - the vehicle stalls.
Found your site and info suggested 'swirl valve' which I passed on to the mechanic. He found that the valve was open and would close during the test. Admitted he was no expert but thought that was the wrong way round...Any Ideas please???
Back on your forum and see that the EGR could be the problem (now it's gettin scary). Some said its easily cleaned and I'm thinking it may be best to clean this first as the swirl valve looks like lots of cash which I can ill afford at this time of year.
Symptoms in brief:
Sometimes drives well, sometimes s***e.
Began being worse on first start and improved when left running for 5 mins but now seems to have little or no correlation with engine temp.
Worse at low and high speeds.
Service incl fuel filter change made no difference.
Strong smell of diesel at times.
A hiss can now be heard on accelleration (slow on the uptake I know, but I mend people not cars!)
Spanner light on only sometimes.
The engine warning light came on and stayed on once until cleared by the garage.
I was going to go to the stealers but after reading your threads I'm sure they're no better than anyone else and they charge a fortune for the priviledge. My local garage are good and honest I would love to be able to give them some clues!!!
Many many thanks for reading this story, I hope there's a wise man out there!
Happy christmas to all forum members.
