Hi All
Quick question regarding my mondeo. It's a 1.8TD P reg, 157400 miles on the clock.
It's started blowing black smoke from the exhaust when ever I press the accelerator, it seems to get worse once the revs reach about 2000, the car labours when accelerating then suddenly jumps forward as if it has just had a power boost it's at this point the black smoke puffs out the back.
It went to it the garage on Friday, they checked the air filter (replaced about 7000 miles ago at service) and fuel line for blockages, all clear. The garage think it may be a blocked intercooler and that it is affecting the turbo, at the moment I'm waiting for the garage to contact me as they are trying to find a second hand intercooler as they have said a new one will be expensive (the garage is very good and have looked after my car since I've had it).
Is there anything else this could be?
I've had a lot of work done on the car in the last 12 months (this is how long I have owned it), cambelt change, new starter motor, new brakes front (discs and pads) and back, new heater matrix, new radiator, new fuel shut off valve and full servicing and a bit more and the car is due it's MOT in about 4 weeks time, is it worth perservering?(spelling, sorry) the down side is I can't afford to go out and spend alot on another car.

Sounds like a stuck-open EGR valve. [Never seen a blocked intercooler.]
You've done most of the usual suspects; the MkII was the best of the bunch, so I'd stick with it. 158K is nothing on that engine - even if it's genuine.

Hi Could you tell me what an EGR valve does/is (sorry, I can be abit thick at times) and is it something we can check ourselves.
Thanks

It's the round tin thing on the exhaust manifold, down below the intercooler, with the braided hose going to it. It feeds exhaust gas back into the engine for emission purposes.

Thanks
I have read that it is possible to clean the EGR valve, possible solution instead of replacing it, any ideas how to go about this?

Hi,
I'm no expert, just an enthusiastic DIYer, but several people with simular problems with various cars are advised to change the Air filter, put diesel additive in the fuel, take it for a long drive at high revs (Keeping it in third gear, or as some people like to say 'An Italian Service!)
Inter Coolers are expensive as one of our daughters found out. She asked if I could do anything with hers which was leaking. Fortunately the leak was at one end so I literatly Chopped the offending section out and resealed it. I said it would more than likely reduce power but since I've done that (on a Ford Focus 'W' plate) she has said it has MORE power and her MPG is up and a lot quieter. It worked and she is happy.
I would take the Intercooler off and try & clean it with parafin and thoughorly rinse with fresh water. Allow it to dry properly. It may work, unless someone out there thinks that it could be dangerous.
Hope this is of some help

possible mass airflow sensor maf, measure's the amount of air going into engine

Had a similar problem with my Toledo TDI. After checking the Air filter and Air flow sensor I turned to the EGR. Unplugged the vacuum to check and yes indeed it helped, but the ultimate problem was caused by a partially restricted intake manifold, particularly the two ports nearest the EGR. I took the manifold off to clean but if you are not confident to do so, maybe something like Seafoam or the Ecotek equivalent "de-coke in a can" may help. Not sure your neighbours will appreciate it though ;-) Well, they have BBQs when your windows are open, don't they?

As some for you may remember (earlier post), I was having a problem with my mondeo puffing out black smoke constantly, I was told I needed a new intercooler, after posting on the forum and getting some sound advice I consulted another garage and it did turn out to be the EGR valve, a new EGR solenoid valve was fitted (we were struggling to find a second hand EGR valve, new one cost £251+VAT, that's half the value of the car) and a diesel treatment put in to try and clear it, no joy. the day before the car was due to go in and have the new valve fitted and MOT the spring coil on front offside wheel snapped, the car has now been sold as spares (we had it for a year and every month it was in the garage having something done, hence we had had enough).
we've now got a ford escort 1.6 1999, 85000 on the clock with very little tax and only a week remaining on the MOT for £300, MOT'd it today and it passed with flying colours and with no advisory notices either. We bought it off a local man who just wanted rid of it as he didn't have the space for it anymore. We are WELL PLEASED and I think it's safe to say a REAL BARGAIN.
Thank you to those who offered advice, you were spot on.
CHEERS GUYS
Joined up with the original post - nice bit of closure !
