Hi, wonder if anyone can help on this. Have tried looking on the forum but not seen a problem quite like this.
I have a 150 CDTi on an 05 plate. It has 45K on the clock and I've had it since 42K. I bought it privately through ebay.
When I first got it the emissions light was on and so I took it into a dealer and the EGR valve was replaced. I took this on the chin and the person who sold it to me contributed to the repair.
However, right after that the fault light started to come on when the engine was cold. It would go off after about 10 mins (when the engine had warmed up).
I also noticed another problem. When I drove the car a bit harder. e.g. over 2.5K revs for instance on the motorway or just having a bit of fun accelerating hard, the car performed brilliantly with loads of pull and all seemed well.
The problem arose when I slowed and was waiting at a junction or traffic lights. There'd be a strong sweet diesel smell come into the cabin. This would fade as I carried on driving but when I paused the car again or got out at the end of the journey it would come back. Its really strong when I get out of the car.
I took the car into my local dealer who had replaced the EGR valve and they listened to my fault description and checked the error codes. They tried a few things but weren't able to solve the problem and suggested I take it to a main dealer. I took it to Lookers Warrington and (eventually) they diagnosed the problem as 2 glow plugs and replaced them. They said they weren't burning off the diesel properly which was causing the smell. This sound feasible so I agreed. This stopped the warning light coming on but the diesel issue is still there. If I drive the car really gently all's well but as soon as I go over 2.5K - 3K then when I slow down I can smell the diesel. This was about 4 weeks ago and the car performance feels great. It has done a trip to London and back with no ill effects apart from this smell when its driven a little harder.
Has anyone got any ideas or pointers?
