Can you put your car details in your signature, go to settings top right, then halfway down on the left, under "My Settings" select "Edit Signature". Put your car model, engine size, year and rough mileage in, it helps give accurate advice, though I assume you have a diesel, we don't know if it's an electronic or vacuum actuated turbo.

 

put details in my signature, colour same as yours, ty for your reply

 

Still can't see your signature....

I think the problem may be wiring related, see here:

Do you know if you have the vacuum or electronic turbo?

Is the fault intermittent?

I don't think it is unsafe to drive.

 

Thanks Benedict, after my service and a good burn up on the motorway for a few days my engine is running sweet again, still have engine malfunction light on and was wondering if I diconnect the battery it might reset itself, I know I will have to get code to reset my radio and its the one thing that was not in my book.Thank you for your help.

 

No need to do that, the code can be reset. Have you got a code reader? If you live near me I can re set it. If not post your location and someone may be able to reset it for you.

I still suspect you have a wiring issue though.

 

I believe I have just cured my P0235 fault. It would only come on at low revs, idling in traffic, pulling up to a junction etc.

I fitted a new MAP sensor; about £25 from Tansit Parts on Ebay. It was listed for a 2.2D Mondeo. Really fiddly to fit though.

So far so good, the P0235 hasn't returned.

One thing I did note, was that the MAP sensor reading on the live data on my code reader: with the old sensor, the value would drop below 100 at idle. The new sensor is 110 or higher at idle.

 

Thanks for your offer Benedict but a little to far for you I live in Lancashire, I think I have put everything in my signature and profile now location and such, so maybe someone close by might help

 

Code readers are cheap if you have something to connect them to though.

 

Hang on Johnb has topped my low mileage on 2004 2.0D 75K now on mine :roll:

 

What do you think about this code reader Car fault reader code scanner diagnostic tool OBD 2 CAN | eBay I do have a laptop and I phone if there is something better that works through these, but this look a handy device.

 

hope to use mine more this year a lot more motorways here so maybe catch you up

 

Hi Benedict
i got a scanner and got same fault code but was unable to erase it, its a vacuum turbo where do I find wires to check for fault.
thanking you .

 

I don't know where the MAP sensor is but as Winco has just changed his perhaps he can advise. I would check and clean the connector to it, then replace if it still throws the same error. Also, can your reader display turbo boost pressure? If so read it at idle and whilst reving and post the results here.

 

The map sensor is located on the hose that comes from the bottom of the egr where it meets the elbow from the intercooler.

 

Many thanks, it'll probably get damp there so I would've thought using contact cleaner on the connectors first may save some hassle and expense, though the sensors are not expensive.

 

Problem resovled, car was in limp mode shows what type of driving I do thought as it felt like it was running ok around town and could do 70 on the moterway it was ok, had it into a garage and checked and it was the MAP once replaced it is back to its oldself and what a difference, at a cost of £276 and to me worth it, Thanking all for there help.

 

Out of interest how much was the sensor?

 

Not to sure not got my invoice , but think it was £76 or £86

 

Cheers. So around 200 for labour then?

 

labour and vat around £200
