1. Sometimes when trying to start the engine, i turn the key and i get a high pitched whirring sound. Then i will try agin and it will start ok.
2. While sitting around 70mph, i can feel the speed fluctuate, it will slow down slightly before speeding up again, as soon as it speeds up the engine management light comes on, it goes off again when i slow down to about 50mph.
3. Traction control light and hill descent light come on all the time, usually after breaking or when slowing down with the gears.
4. While speeding up through all the gears, i hear noise that sounds like the fans blowing, it stops as soon as i take my foot off the accelarator.

Hi,

Having a few different problems with my 2004 td4 commercial.

1. Sometimes when trying to start the engine, i turn the key and i get a high pitched whirring sound. Then i will try agin and it will start ok.
2. While sitting around 70mph, i can feel the speed fluctuate, it will slow down slightly before speeding up again, as soon as it speeds up the engine management light comes on, it goes off again when i slow down to about 50mph.

4. While speeding up through all the gears, i hear noise that sounds like the fans blowing, it stops as soon as i take my foot off the accelarator.

I recently had my clutch changed, soon after i had to return it as i had problems getting it into gear, i got this fixed but now the problem has returned and it is going back in this weekend, the Mechanic said it was the hydraulic cylinder which he will fix.

Has anyone on here experienced these same problems as me, any ideas how to fix them or what parts i need, and if they could be directly related to having my clutch changed: ie poor workmanship?

Thanks

hi danboy,just a point on your clutch prob, was the slave cylinder renewed when the guy did your clutch? if it was then your problem sounds like the master cylinder.most of the other probs sound like simple fixes as others have advised .tim
