Thread: td5 bad throttle response

Clean the MAP sensor before buying another. I had 2 MAP sensors so that I could swap out the dirty one and clean it later using a solvent.

If he has access to a Nanocom, he could also check the readings, that's what I did with mine, then I tried cleaning it but I suppose after somewhere around 450,000 it had just had it. Also, with Nanocom, you can put an SD card in it, go for a drive and record the readings, and analyse them

Just swapped the MAP sensor to an new one (BOSCH [COLOR=rgba(0, 0, 0, 0.9)]0281002205) and nothing has changed, maybe it can be a faulty throttle ?

PS: [/COLOR]While I was driving by the streets to test the new map sensor, I had to stop the vehicle in the middle of a steep climb, and when trying to pull away again it didnt even move from its place , I had to select LOW traction mode to be able to move up and finish climbing Haha.

PS 2: When i turn on the A/C i have the same "lack of power" described above

You really need to plug in a nanocom or similar to go further

My TD5 days were a long time ago but doesn't the MAF get its 12V via a loom that runs across the front of the head and that loom can chaff when the plastic cover deteriorates and cause the fuse to blow when short circuited, thus leaving the MAF without 12V power?

Please do this if you can, someone within striking distance will have one.

Depending on the revision of the Auto controller you have, you may be able to retrieve some information from that with an OBD2 reader.

Didnt find any nanocom on sale on my country at good price, and as i dont know any owner of it i had to buy an generic scan tool to check some parameters to go further.
Well it just arrived here, and i connected it in the car, there are some parameters i found.

Obs1: i forgot to take a shot of MAF numbers, but it says 0.00 kg/h
Obs2: i recently tested MAF wiring with an multimeter and It seems to be ok, it is not interrupted.
Obs3: curiously BCU odometer shows a different mileage than the dashboard

From what I understand, the symbol in the bottom left corner of the LCD is because the odometer and the BCU are not synced
