Vw tdi slow down shudder 

You could definitely hear the difference on your video. You’ve got to love it when you can repair a car with just a few clicks on the old keyboard and an understanding of what your working on.

I would say the real cause was not addressed. You found a way around the problem, but the problem remained. My guess is that for some reason the computer miscalculated the amount of fuel. And the reason was in some sensor, I guess the O2 sensor. The computer can change the values ​​so that the sensors give the correct value to the computer, but this is not correct, because the crack through which some of the sensors get additional air remains. Sorry, but I don't consider playing with the car's computer to fix the car, rather to cover up the problem, making the next mechanic's job even more difficult because you hid any symptoms that might point to an air leak. But if the car was for quick sale, good job with fixing the problem :) and as a warning to others, even a properly working car can bring surprises later.

My car is a 2006 audi a4 2.0 tdi can someone who does remaps do something like this to higher my iq

Clean that poor intake Or least stop the emissions at least Long live the beetle ‘99 336k

I have something similar. The IQ is way low but at idle it jumps about along with the voltage on the modulating piston. My cold start duty cycle is also doing erratic things on idle. Once some throttle is applied everything stabilises but the IQ is still very low. Injection timing is adjusted spot on. This all started when i swapped from the old MSA15 ECU to an EDC15VM+ ECU (ALH) so i could run my AHU on a VNT turbo. Prior to this it was all ok. I had to use a different loom which i belled out a couple of times to confirm and record what was what. I can only think it's a wiring issue but i have no fault codes.

YES !! After injection pump o-ring replace, and timing to perfect.. thganks for those vids too, it idled rough.I will be trying this in the morning.. Thanks.

Why is slowdown shudder happening? Is there something mechanical with a pump internals or bad fuel that lowered IQ value to almost 0?

Love the triple grab at the non existent handle lol

DO IT!!!!!

Thats not totally the right way that still to low of an iq the iq is supposed to between 3-5 for stock if I recall right

nice video ty. i have audi b6 2003 1.9tdi and mine does that sometimes when i stop at red light or something. that adaptation what did it do to egr cicle and for fuel consum. couse i sow similar video abaut egr cicle and for that the number u entered must go in max value. gretings from croatia (ps sory for my bad writing)

I’ve a 1.9 ATD 2003 beetle and it’s yellow 👌🏼 I slowed my idle down from 985 to 816 using vcds

Hello! I have a 1.9 tdi agr 90 hp stock, the IQ is 2.8 / 3.0 MG with a temperature of 92 ° at idle and with everything off, are these values ​​correct? If I increase the IQ more (close to 3.6 / 3.8 MG) I will to achieve better performance? thank you so much

Ok. But the cause of the shudder? Worn/clogged injectors, bigger nossle injectors intalled.....?

Hi injection quantity is bouncing around 1.5 and 2.5 mg it supoossed to be around 3.0 to 9.0 mg what could be the problem all 4 injectors are reading within range audi a4 b7 2.0 tdi 2006 thanks

This video just make me realize that if you own a VW product you really need a VAG COM scanner or something close to it.

I have done about everything but this to a BHW it has the shudder at idle and when slowing down, camshaft has been replaced, balance shaft delete, new engine mounts, trans mounts and it still shakes and shudders the doors steering wheel and glass, I’m going to have to look into this

Solve it . Good video !!

This video fixed the exact problem my ALH was having. Thank you for uploading this!

You had to do some Hammer mode.. Because 2mg is in your case the minimum adjust number. In my case (Same engine) the stock number is on 3mg.

Hello i have similar problem on a 1.9 PD engine but it stops when the engine is warm (the injectors are tested its not them)

Bonjour monsieur Une fois de plus je vous tire chapeau pour cette magnifique vidéo Honnêtement avec vous j'adore et j'apprends beaucoup Que dieu vous protège

But wouldn't the underlying problem really be bad injectors? While that worked for now its really not fixed and the next guy that puts injectors in it will not know what you did and correct it.

thanks, I already solved a problem of three, I am missing two, the start of the actual injection varies a lot and the deviation of the injection quantity in the cylinders is, cylinder 1 = 1.88mg / str, cylinder 2 = 1.88, cylinder 3 = -1.88, cylinder 4 = -1.88. can you help me please, THANK YOU.

Great video thanks for sharing your knowledge..

As my car is doing the same shaking at idle

Bonjour Merci pour ce tuto Excellente journée à vous monsieur

Does it also give you a bit more power ?

Thanks for this video, very useful.

Hello I have a problem with a golf 4 ALH . The cylinder head gasket was burned and I went to the mechanic to open the engine and yesterday the pinched cylinder head gasket. I made the flat at the cylinder head plus changed valves etc. I made it head tail. The mechanic looked at the engine saying k is a bit worn out he suggested I segment it plus bearings bearings etc made tail head .... I also bought the new clutches plus the refurbished turbine at the clutches The problem is k THE MACHINE NEVER MAKES NO POWER I changed the flowmeter sensor sensor map sensor n75 sensor n18 Log in running turbine puts pressure on parameters but does not fire or run Vacuum checked everything ok Without errors I was at several mechanics and did not give up. no power PLEESE HELP

Where are you located?

Really enjoy your videos

Excellent - thank you !

will this be the same for the BLS tdi 09 plate ?

Thanks for showing us your secrets of the trade. Good job

How did you get the lowest and highest values, in order to know what to set it at? Awesome video. Learning more and more for my vcds. Thank you buddy 💪
