Poor Performance... Smokey...

[Huxo]

Hi all, first post from a newbie.

Got some issues going on with my Mondeo 06 plate (51k miles) 2.0 TDCI. Car drives well but then whilst at low speeds (circa 30mph at 2k revs), I feel lumpy power delivery - this will carry on unless I accelerate a little. Also, this morning, I approached a roundabout and had to back off the gas when checking for traffic. My way was clear (still in 2nd gear with speed about 15mph) but when I went to accelerate again, I got nothing for about 3 seconds until the turbo finally opened up. I looked in the rear view and saw a large cloud of black - presumably all the unburnt extra fuel pumped in whilst trying to accelerate? There are no warning lights on the dash at any point.

What's going on?? I removed the EGR last Saturday to try and solve the lumpiness and gave it good clean with carb cleaner (quite easy, but damn, it was messy!). Car seemed very good, not smokey for about 2 days afterwards

My concern is that I've been here before with my last car - an Audi A4 2.0 TDI. That developed the same issues and got progressively worse (got rid of it as it was costing a fortune in garage bills). I lost total and utter faith in that car and I don't want the same thing to happen again! Starting to think that it's either the way I drive diesel cars or the injector cleaner additive I add when filling up is actually poison... as it didn't seem to do this before I started using it...

Anybody got any hints, tips or suggestions? Gutted as the car is a relatively low miler and it was last serviced in May.

Paul.

check the intercooler pipe for splits, its the large pipe from the bottom of the egr valve
