Just a quick update, after fitting the used SAGEM MAF I have now managed to go for a reasonable drive around to get the ECU to adapt to the change. It is now a very different car, smooth as silk, idles as steady as a rock, no hesitation when...
Believe me there were a multitude of cuss words, some really, really naughty ones :)
Funny thing is a local chap pulled in in a s3 Landy and asked if I wanted to sell it, hmm, the thought had been crossing my mind, trouble is it would be like...
Just to update. I have again tried the 2 new MAFs with the same ending, chugging black smoke and backfiring. I have now fitted a good used one from James Coleman (SAGEM OEM) and tried it, it started but was really rough. I checked for any faults...
Water ingress in the nearside rear quarter is not unknown or corroded connectors. Have you looked in the spare wheel well? The tailgate seals are a know problem with an official mod to fix the leaks, bend the flange on which the seal is mounted...
The first one looks like a deliberately drilled hole? If you use an arc welder, disconnect the battery negative or you may destroy the electronics. Personally, I would treat with Phosphoric acid to kill the rust and then repair with fibre...
All sorted, pretty easy TBH, the plastic latch piece on both had got gunked up with old grease, dirt and rust, a few squirts of brake cleaner and nice new lube. I didn't even need to remove the latches, both smooth as silk now and close and open...
The lower one has a screw in the door the upper is held with the pin and sac cup. I am not sure if there is a screw in the front of the door, mine is just clip on with the above fittings. I have some in my spares boxes just in case :)
Also check that GEMS is set for the correct engine size. 2nd screen in settings menu.
Once you get the settings in the right ballpark, you should do some drive cycles to train the ECU.
Many thanks, lotsa info to get on with there, the engine was idling on the old MAF for all screen shots, odd about the airflow bit, I did wonder but I am not au fait with using engine diagnostics so I wouldn't fully know what I am looking at!
Thanks Pete,
My MAF only has 3 pins, it is a GEMS and not Bosch/Motronic.
When I put the new MAF in (either one) I cannot physically drive the car because it won't rev no matter how hard I press the pedal.
The readings do change when revving on...
Thanks Pete, I have done the reset adaptive values with the Nano but both of the new MAFs still overfuel and I cannot get a tickover let alone any revs, as soon as I unplug either of them the engine then goes to idle and runs and revs etc. If I...
There's only one Adaptive Values Reset in Nanocom for either GEMS or Thor. (Can't remember which you have) No option to reset MAF, O2, etc separately because the ECU learns using all of the sensors together.
Have you also checked the O2...
Mines a 4.6 HSE Petrol, where do I check the MAP? When I replaced the MAF 11 years or so ago I just fitted it, plugged it in and all was ok, this time not so. The MAF shows up when doing the fault check so I would assume again that the thing is...
There are no adaptive setting for the MAF on the diesel. all of the above could still be a dodgy connection. Worth checking that the MAP sensor is working.
Hi Keith, I would have thought that if it was the connector or connections that it would make no difference with it plugged or unplugged. If I start the car with either of the new MAFs the thing overfuels and I cannot get it to rev, if I pull the...
Since I put the original MAF in the engine is doing what it is supposed to so I am assuming the other bits are doing what they should, I will run a check though. I would like to put one of the new ones on though because I don't trust the old one...
Right, I have checked the old MAF with the Nanocom and it came up with fault 102 circuit low input. I cleared it and restarted but the fault returned. I have 2 brand new MAFs so I installed the first and tried starting, the thing just threw out...
Hi Pete,
Many thanks for that, I have done a couple of my latches (rear) in the past and I wish I had seen this video before! All the latches do what they are supposed to and the internal handles open the door easily, they just dont latch when...
