Throttle Body + EGR Cleaning - Seat Leon 1m / Golf 4 / Toledo 2 / Bora (code AZD & BCB)

In this tutorial I will show you how to clean the throttle body and EGR valve on the 1.6 16v engine (codes AZD & BCB).
You can use this tutorial for Seat Leon 1m, Toledo 2, Vw golf 4 & Bora.
You don't need to calibrate the throttle body after installing it back. But the battery must be disconnected the entire time you're working on the throttle body & EGR valve.
Don't move the butterfly valve! If you move it, you may need to calibrate it with a VAG Com interface.

Thanx Sorin. I salute u my main man. I used this tutorial to clean throttle body and EGR valve in my VW polo 9n.. BBY engine..

[@Dobsikus]

Great video, it's exactly what I need as info for the procedure on my Golf Mk IV! Last summer after fixing my door lock (something unrelated) those ba****ds deliberately tore the head of one of the 10mm screws holding this pipe to the collector. I could not get the metal out so I just left it with one bolt since then. Now I'm constantly getting "EGR System P0402 - 35-00 - Excessive Flow" error and it seems obvious that I need to re-drill and recreate the hole somehow to tighten it properly again... Thanks to your video I'll be able to take apart everything and also clean my EGR valve as a bonus. :)

Sorin, really good tutorial.I did it as explained. Just one important information was missing: at removing the egr pipe (at 4:30) the existing of the 5th screw in the middle of the pipe was not mentioned, I had only removed the 2 screws at the throttle and at the egr valve. I wondered and was searching a long time why the pipe was not removable. just jiggling had no sucess :-)

[@Sorin_DIY_Mechanical_Nerd]

hi. I've mentioned the screw at 3:55. you need an 8mm wrench for it.

Are you getting code 'P0171 System Too Lean Bank 1'? Mine is running lumpy/lean but I can't find any vacuum leak or other cause.

[@AlanHead]

@@terencejay8845 I had that error but it cleared after replacing the coil pack for one of the cylinders, giving it a dose of injector cleaner, and a couple of tanks of super unleaded. Cutting out was still happening occasionally but unplugging the EGR valve has fixed it temporarily (obviously it lights the check engine light and also triggers the "emissions workshop" message too)

[@mulczas88]

Hello, For BCB engine you can clean all throttle body without VAG COM adaptation by software. When you will drive around a few kilometers your throttle will be adaption automatically by ECU. I tested this solution.

[@Sorin_DIY_Mechanical_Nerd]

you're right, for most cases... that's what I said in my video, I never had that problem. but if you read the comments for my both "throttle body cleaning" videos, you'll see that some people had problems with the throttle body after cleaning it. maybe they moved the interior valve, or something.. the removal/cleaning procedure is similar for other 1.6 and 1.4 l VAG engines as well. I don't take responsibility if something goes wrong during the cleaning process, or if the throttle body needs calibration. that is way I said - the throttle body MAY need calibration.

Thank you Sorin, excellent video tutorial, i will give this a go on my 1.4 16V BBY Skoda. Have a P0401 Insufficient flow error so must be done. One question is was wondering about, you clean the TB and the EGR valve but NOT he EGR pipe connecting them. I haven't started yet, so cannot see if it's dirty, and also can't find a video where the pipe is cleaned, i would suspect it has as much carbon build-up as the EGR valve and the TB, does it make sense to get some Carb cleaner down that pipe?

[@Sorin_DIY_Mechanical_Nerd]

Hi Soren. Thanks for the video! I have a question - i broke off the head of one of the bolts for the pipe under the throttle body - is it dangerous to leave it like that ? Do you think i can take it out somehow?

[@Sorin_DIY_Mechanical_Nerd]

hi. that is not good.. it's a little dangerous for the engine, because the pipe it's not sealed properly. the engine can take false air (with dust) through there. the engine idle may fluctuate. you can try to drill a small hole (or 2) in the rest of the bolt. you need a good quality drill bit. then force something in the hole, like a screwdriver, and unscrew the bolt. or you can remove (or "eat" through) some plastic around the bolt, about 2-3 mm. then grab it with pliers and unscrew it.

The Throttle Body Butterfly is held in the closed position by a spring, you can push it without any worries. I didn't disconnect the battery while working on the Throttle Body and didn't have any problems. I didn't work on the EGR yet, but it's the next item on my list. Why didn't you take out the EGR Pipe? You should have cleaned it too.

[@test88742]

Hi, many thanks for your videos! I have the same Leon 2003 1.6 16v with 170k km. Mine is consuming quite a lot of oil but I dont see it leaking anywhere. Do you have any ideas what could I check / replace? Breather filter oilfilter, what could affect to oil consumption?

[@Sorin_DIY_Mechanical_Nerd]

hi. you can try another type of engine oil, with a higher viscosity. for example if you are using 5W30, when it's time to change the oil, try 10W40. you can try MOTUL, it's recommended for this engine. then compare how much oil is consuming in the same interval. remove the ignition coils, check if the coils or the spark plugs are covered in oil. the rocker cover gasket may leak, and the oil is collecting there. I saw this problem on my engine and other engines. you can clean/degrease your engine bay, especially the oil pan. take the car for a ride around the city, rev the engine a bit. then check the oil pan gasket and other gaskets with a paper napkin. if it's leaking, even just a drop, in time it will accumulate. check the oil filler cap gasket, I've made a video about it... ..or the piston rings may be faulty and the engine it's just burning the oil... mine is consuming about 300 - 400 ml of oil in 9000 km.

[@test88742]

Many thanks! Lets see if I can put 10W40...in my location it goes every winter to -35 but of course I heat the car before starting. Spark plugs were clean and I didn't see oil leakin from the engine but I will follow the situation more carefully. Maybe I will soon change the oil to 10W40 and put new oil filter.

Hello! If I remove and clean the components, you need to re-calibrate it with this specific device, or can the ignition be plugged in several times in the video? Why is it necessary to disconnect the battery? Thanks for the answer!

[@Sorin_DIY_Mechanical_Nerd]

hi. you need to disconnect the battery, so the onboard computer will not know that you unplug the throttle body. I removed the throttle body from my car 3 times. I also helped other friends to clean it. I followed all the steps and didn't need to calibrate it. but I noticed some people commented, that they needed to calibrate the throttle body after cleaning it. my throttle body did decalibrated from other reasons... so I can't assure you 100% that it will not need calibration. it also depend on the engine code, other types of throttle bodies may need calibration. it should not decalibrate, but you will do it on your own risk... if it decalibrates, you need a vcds interface to calibrate it.

[@Sorin_DIY_Mechanical_Nerd]

hi. these errors can occur for several reasons. if you have a cable throttle body, you need to check the cable when the throttle is closed. the cable needs to have a bit of a slack in it. another common problem is a fault in the wiring, plug, connector at the throttle body. you need an auto electrician to check them. or the least common reason, a fault inside the throttle body. I think the problem is in the wiring/throttle connector (this is just an opinion).

Hi, I cleaned the throttle body that was very dirty on the back side and I saw the return of the egr is very dirty too. When I put some load eg lights, steering or clutch, rpms go down for a bit.

[@Sorin_DIY_Mechanical_Nerd]

hi. after you drive for a few km, the idling revs will self adapt. but there will still be some small variation of the idling, when you activate different loads on the engine, this is normal. this is not affected by the EGR.

[@Sorin_DIY_Mechanical_Nerd]

hi. did you disconnect the battery? if the EPC indicator persists, there could be a problem with the throttle system (pedal, wires, on-board computer, throttle body). if the idling fluctuate, the throttle body most likely needs calibration with a VAG-Com interface. it happened to my once. if not, there could be another problem with the engine, that affects the throttle body. in this case you should check the error codes with a VAG-Com interface, before you try anything else.

Sorin - DIY Mechanical Nerd.. Yea I've done all you mentioned above. ODB gives P0106, which indicates problems in intake manifold pressure. I changed MAP sensor and it didn't solve the problem.

Hey Sorin, i have a golf 4 BCB engine, i have EGR error code, if i try to clean the EGR valve, will the error dissapear by it self or do i have to delete it?

[@Sorin_DIY_Mechanical_Nerd]

hi. if the EGR valve it's just stuck, after you clean it, it should work fine. but if the EGR it's faulty, you will need to replace it. either way, the error should remain stored on the on-board computer memory. but it won't affect the car in any way. it is recommended to delete the error, after you clean the EGR. drive a few days. then check if the (same or other) error reappear. this way you will know if the problem was fixed. if the EGR is working fine, and you don't delete the error, after a few months the error may disappear. I had a comfort module error, that was keep reappearing. after a few months it just disappeared by itself. hope this helps...

why is it getting so dirty after 20 k klms is it because it is recirculating the dirt around the pipe work and to stop pollutants getting into the air we breath ,, just woundering thats all ,, good video Sorin

[@Sorin_DIY_Mechanical_Nerd]

hi. the recirculated exhaust brings ash and other stuff back into the throttle body. this dirt sticks to the throttle body and intake manifold with the help of the oil fumes and crankcase gases coming from the carter tube. there is a tube in the back of the engine air filter, which brings these gases back into the throttle body. if you see the air filter colored with a brawn substance, it means that the engine is begins to be worn and it produces a lot of these gases.

What camera and microphone are you using?

Am vazut la altii ca lasa egr ul in benzina ... Sau dau cu spray de frane.. Tu ce părere ai?

[@Sorin_DIY_Mechanical_Nerd]

Salut. Un spray de curatat carburator/clapeta de acceleratie ar trebui sa fie de ajuns pentru a curata clapeta de acceleratie si EGR. sprayul curata doar depunerile pe partea exterioara, clapeta/valva. daca sunt probleme cu partea interioara si anume circuitul, motoras, rotite, degeaba folosesti mai multe sprayuri sau sa le lasi in benzina, ca nu se repara. curatarea e doar pentru intretinere, daca e deja defacta piesa, trebuie schimbata.

Should u dry inside with cloth or something? Or just leave?

[@Sorin_DIY_Mechanical_Nerd]

you don't need a cloth. the excess cleaner will evaporate very fast.

Hi what about the pipe!?!? Great instructional video!!!

[@Sorin_DIY_Mechanical_Nerd]

it's very difficult to get the pipe out from the engine bay. the pipe was not clogged. I've clean it a year ago, by tilting it and spraying cleaner through the top of the pipe.

[@anastasiosmichalakopoulos6044]

Thank you for your response!!

Is it the same for 1.4?

[@Sorin_DIY_Mechanical_Nerd]

Hi. The method is similar for some 1.4 16v engines, like the engine code AUB. But there are some differences, like screws sizes. You will need an allen wrench set.

Can I also use breakcleaner?

[@Sorin_DIY_Mechanical_Nerd]

no. I've tried, it doesn't work.

Hi Sorin, I have an AZD. I accidentally snapped the head of one of that bolts that holds the egr pipe to the intake, could this cause my (P0402 - egr flow excessive) fault code? i would really like to get rid of this code, if anybody could help please.

[@Sorin_DIY_Mechanical_Nerd]

hi. I don't think that's the reason for the error. I think the EGR valve is faulty, it doesn't close properly, or it remains blocked on "open". ether way I suggest you first replace the EGR valve support, clean the EGR, delete the error, drive it a few km outside the city and scan again. if the error persists, I think you need to replace the EGR.

[@santrax1066]

@@Sorin_DIY_Mechanical_Nerd Okay thanks for the reply Sorin, I gave the EGR and throttle body a good clean following your video. I cleared the code and it came straight back when I started the car, i'll have a go at replacing the EGR valve next. Great video btw.

Throttle body needs to be re-calibrated anyhow once the wire is disconnected. And btw i hate Volkswagen engines ! egr and all that crapp

Couldn't agree more, their a load of shit, mines just cost me 1500 to get sorted in the end I just sold the piece of shit and bought a toyota.

[@daljitsingh2143]

If you disconnect the battery and don't press on the throttle plate but clean it using a degreaser (alcohol based) you don't need to recalibrate it. If you know how to then do so following the right procedure

because I like all animals, especially my cats and dogs :D

[@frankhoward7645]

Great video however I have one suggestion. Once you've disconnected the ground cable from the battery, there is no reason to disconnect the positive cable. You're wasting your time.
