Turbo boost.......problems

There is quite a lot of information about MFTS and fan switch if you search the forum.

Basically, many cheaper MFTS units read totally wrong, it is this that feeds the temp gauge in the cluster. Get a Behr unit fitted - what brand do you have now?
The rad fan switch in the base of the main rad controls when the fan switches on and off.
The temp sender in the back of the head sends temp information to the ECU

Today I made several checks, as you can see there is a very important difference in degrees Celsius, the radiator switch that activates the fan works perfectly at 90Cº, however the thermometer marks a very high temperature unreal.

I changed another MAF (had 3) and I have put an old one of the ABY that changed it years ago by precaution and ................ seems that it is going much better, I have not been able to prove it well But the feeling has been quite good ........


Thanks LHD tomorrow I will look at the manufacturer, is there any better quality?

Only use Behr MFTS

Good luck!

Edit: There will always be a little difference between the MFTS and the rad fan swich, because the MFTS is in the head (hot area) and the rad fan switch is at the bottom of the rad (colder area) - not that it makes much difference but it means the gauge won't show exactly the 95°C and 102°C for the 2 rad fan switch points...

One other thought, have you checked out the inlet air temperature sensor (IAT) on the inlet manifold?

Hi Mike, yes, check your resistance (Ohms), also clean with spray cleaned with residue 0, thanks for helping.

Hello friends, this is the MTFS that I bought and that is not going well, is it of good quality?

Thank you.

Meyle products are Chinese rubbish I'm afraid.

Argggg ......... that is why it does not work well, tomorrow I will dismantle it and see if I am changed to another brand of better quality (I doubt)

Thanks for answering Nuvo.

Hello friends, checking the throttle butterfly I broke a plastic that holds the cable, I point it in the photo, someone knows how to get it?

Thanks.

About the same price as a Behr MFTS.....

On Monday I will go to a scrapping to catch some of AAN.

MFTS, I have already put back old, I will take to be changed for another time.

Hi, we continue adjusting it and every time it seems that it is better, the accelerator tensioner did not just return to its housing and I have already put it well.

The pressure increases little by little and not as radical as before ..................... now I have to increase the revolutions much more to achieve the same thing as before.

Why could not the car be so radical now?

Greetings and thanks, any advice will do me good to investigate

Hello friends, this week I have been manipulating the potentiometer of the accelerator.

I noticed that the potentiometer that my car was mounted years ago (ABY) is the one on the right of the photo and that belongs to a 3b and that for security replaced a few years ago without knowing that the one that was installed was not part of that motor.

This week I got the potentiometer of an AAN, which from what I've seen the references are the same.

As I installed it (I installed it well) the car started to do strange things (at idle), suddenly began to accelerate alone and the N75 to make fast pulsations (VagCom connected) and output potentiometer 100%, all this being at idle , E moved several times to the accelerator and was solved, but I started to do so .......... and in VagCom error 00518 and 00516 ............... .... so I have deduced that the potentiometer of AAN was broken and I have put the one of ABY again.

I have adjusted everything pretty well and it seems to go better the S2, to see this weekend if I prove it well.

I had an issue with mine a long while back where the switch for throttle closed wasn't working. Easy to test though
